It makes no sense keeping watchdogReset as a separate function which
must be called, since it only contains one instruction: "wdr".
Not only was the code larger by 32 bytes in total, but also much slower
(call+ret take 4 cycles together for no reason in this case).
Surprisingly, doing just this on FW 3.9.3 solves issue #2954 on the one
affected EINSY board, even though it makes not much sense (there must be
some other timing issue).
Another request from our Service dept. - the user shall be prevented
from skipping the intro wizard, because otherwise some preset/calibrated
features will look like not done - especially live-z calibration.
And since there are users, who send a machine to service to perform 1st
layer calibration only, they must not omit the Z-calibration at the
start after shipping.
As the `M0/M1` moved to the beginning of the parser
- parser would not be able to "find" `M1nn` command if the query was `M1` instead of `M1 `
- to be able to "stop/halt" without sending a string and display default message use gcode `M0`
- as there are no `M0nn` gcodes the parser can query `M0` without additional space needed as in `M1 `
- If `M73` `R,S,C,D` values set the LCD Info screen clock switchs between Remaining and Change time
- If Remaining time is 0 while Change time is >0 the clock switchs between Change time and actual printing time
- If Change is 0 while Remaining time is >0 the clock shows the Remaining time
- If both are 0 the clock shows the actual printing time
- `M73 C` values are shown in "Normal" mode
- `M73 D` values are shown in "Stealth" mode
- Changing the speed will try to calculate the espected times and show `?` behind `R` or `C`
- Add parameter `C` to gcode `M73`
- LCD Info screen switches to change time if last `M73` gcode contains `C` parameter
- Examples:
- `M73 P5 R120` will display on LCD ` SD 5% 02:00R ` if it is printing at 100% speed
- `M73 P5 R120 C60` will display on LCD ` SD 5% 01:00C ` if it is printing at 100% speed
Slicers can generate "Time to change/pause/user interaction" using `C<mins:0-65535>` parameter to "overwrite" the remaining print time.
To switch between time to change and remaining time just send in intervals `M73` with or without `C` parameter.
The functions find_bed_induction_sensor_point_* have conflicting
extern and inline declarations.
These are used outside of the compilation unit only, and thus there's no
point in defining them inline.
This causes a compilation failure at O1 and above, which is strangely
avoided at Os.
... looks like I've been able to reduce the code by 80B by using the
clamp999() function. There are other spots this function can be used as
well, I didn't touch those yet.
upon request from our Service dept. - it is to do the same stuff like
Shipping prep., but keep the printer's stats intact. Still, this has to
be verified and may undergo some further changes.
Acceleration settings need to be saved in UVLO, since these are often
changed/set during a print. This is especially important for travel and
retract acceleration, which is usually set once per-print.
Saving and restoring is not 100% correct.
We save the current front-end value, which might ahead of the backend
when UVLO is triggered. Print acceleration, likely the most significant,
should be saved in the block buffer to be accurate.
Acceleration needs to be restored after the UVLO Z repositioning is
performed, using an M204 command. This is correct, however we don't save
the _temporary_ max acceleration limits set via M201, which could be
higher than the saved limits (via M500). This could result in lower
clamped values compared to the original print.
Maximum acceleration/jerk/feedrate limits should _all_ be saved in UVLO
in the future.
Allow to separate extrusion and travel acceleration settings using M204,
as Marlin 1.1.x and 2.x does using M204 T.
This allows to reduce the number of instructions required during
printing, since resetting the acceleration for travel moves is no longer
required and can be done a single time during the print.
Provision for this parameter was pre-existing, but not implemented.
M204 has two forms: the lagacy format (Marlin <1.1):
M204 S[print-acc] T[retract-acc]
and the newer format:
M204 P[print-acc] R[retract-acc] T[travel-acc]
The distinction in the MK3 FW is done based on the presence of the P
parameter. If P is seen, the new format is adoped. In the new format
however, M204 T was ignored until this change.
To keep backward compatibility, M204 S[acc] will set both print and
travel acceleration, which is identical in behavior to recent versions
of Marlin.
Depending if SD or USB/host print the firmware sends
- SD print: `// action:paused` or `// action:resumed` are send to inform USB/Host
- USB/host print: `// action:pause` or `// action:resume` are send to trigger the USB/host to handle it
- USB/host must handle `// action:pause` and `// action:resume` correctly to work
- Tested with Octoprint
- It handles every thing correctly
- Any combination of Octoprint and/or LCD `pause` and `resume` working correctly
- Tested with Pronterface
- It pauses BUT doesn't send the printer in pause position, and so it is not possible to `resume` from LCD menu
- I guess some Macros can fix that.
- Repetier Host/Server documentation shows that it should work. Not tested.
Could save 56 bytes in first step and additional 38 bytes adding `MSG_PAUSE_PRINT` to messages.c/.h
Updated `lang_en*.txt`
@todo Polish translation is 19 characters long (it still fits) BUT should be corrected to 18 chars.
It was left in the code in one of the refactoring/optimization passes.
It really didn't do any harm, but was limiting the performance of the
skipping algorithm.
+ some verification code added - will be removed after successful tests
fastio relies on macros for pin definitions, so we cannot use the const
declaration in Sd2PinMap or the arduino's definition.
Declare SDA/SCL_PIN into pins.h based on the current MCU, which is
identical in all our variants.
Remove the conflicting/unused declaration in Sd2PinMap.
- Start saving instructions as the whole PR was >1KB long.
- It turned out the compiler was unable to understand the core skipping
cycle and an ASM version had to be used.
- Add seekSet aware of the G-code filter
This is an extension/optimization of PR #2956.
It uses the cached 512B block buffer to avoid heavy-weight read() in SdBaseFile.
Even though this principle allowed the AVR to skip ~600KB of data within ~5 seconds,
the impact on code base is huge, especially into well proven and long-term stable
parts like reading a file from the SD card.
The sole purpose of this PR is to show/verify the possibility of the AVR CPU
in relation to adding thumbnails into MK3 G-codes.
Moreover, this PR shall not be merged unless the missing/commented features
are restored - especially file seeking and M84 search.
PFW-1175
If there are large blocks of comments in the G-code,
the printer may get shot down by its own watchdog.
Watchdog is generally set to 4s and updated only
in manage_heaters (and some other spots in some specific cases).
So far, the code reading the file and feeding it into Marlin
cycles indefinitely until it finds valid G-code lines and fills up the
command queue.
If the block is large enough, the printer cannot read it completely
within those 4s.
A simple workaround - bail out after some consecutive empty/comment
lines to enable other parts of code do their job (especially
manage_heaters).
Tested on MK404, previous FW fails with 600KB of comment lines at the
beginning, this patch survives. The printer even draws some update
on its status screen before starting a real print.
Introduce new macros TMC2130_MINIMUM_DELAY/STEPPER_MINIMUM_DELAY for
blocking pauses.
If MINIMUM_PULSE has defined to be zero, avoid the delay call entirely.
Farmers request having the Change filament menu item always visible in
the main menu and located after the Live Adjust Z (which disappears
after the first few printed layers).
- code_seen("string") -> code_seen_P(PSTR("string")) saved >100B of RAM!
- serial print "." -> '.' saved some code
- extract commonly used string
- SERIAL_PROTOCOLLN("") -> SERIAL_PROTOCOLLN() as no argument is
necessary
Motivation:
- save some RAM joining the autoreport flags into 1 byte
- encapsulate the magic of setting bit masks/features into a class with
a stable public interface
- remove the UI and related stuff to setting a farm number (the
communication protocol must remain intact)
- remove confirmation after print finished ("Print OK")
Both requests are highly welcome, since they allow for lowering the code
size by >1KB

Prevent bad readings/issues if someone changes the bed thermistor that is "better" with lower min values and creates a custom firmware.
The firmware will now be in the range of the PINDAv2 thermistor independant from the bed thermistor (which may change and need adjustments)
- Changed DETECT_SUPERPINDA to SUPERPINDA_SUPPORT as on miniRAMo the thermistor readings below 30°C
aren't accurate egnough to determine if SUPERPINDA is connected or not
- Add LCD toggle menu Settings -> HW Setup -> SuperPINDA [Yes/No] to overwrite SuperPINDA detection
- If EEPROM_PINDA_TEMP_COMPENSTATION is empty = 0xff then detect SuperPINDA by checking thermistor
- If EEPROM_PINDA_TEMP_COMPENSTAION is 0 then forec enable for temperature compensation menues and functions
- If EEPROM_PINDA_TEMP_COMPENSATION is 1 then force disable for temperature compensation menues and functions
When unloading + preheat immediately followed by a load, the carriage is
raised first up to 20mm, then again to 50mm.
With PR #2318 it makes sense to make more space for the extra extrusion
anyway, so make them the same. This moves the carriage only once _while_
preheating, which is nice.
Preheating already raised Z to avoid scorching the PEI sheet, as does
filament loading/unloading to allow for excess material to be removed.
However, when loading/autoloading/unloading via the LCD with a cold
nozzle the preheating menu is performed before the carriage is raised,
leaving the carriage close to the sheet while heating the nozzle.
Pre-raise the carriage already while waiting, so that the subsequent
move is automagically skipped.
Set bFilamentWaitingFlag only once to perform both the LCD
initialization and raising to the appropriate height.
Should fix#2761
The wiring for the PAT9125 on RAMBo10a boards is not directly connected

After fixing some LA15 issues, the strenght of LA15 increased.
As such, re-adjust the conversion factor so that:
Start K10 => 0.01 (previous minimum was K15)
PLA K30 => 0.05 (was 0.07, optimal 0.045-0.06)
PETG K45 => 0.08 (was 0.13, optimal 0.07-0.11 depending on material/temp)
- Only implement a single syncronous read/write function to read a byte,
since that's all we need currently
- Implement a compact IR_SENSOR probe for PAT9125
- Saves 242 bytes compared to PAT9125_SWI2C
The temperature and fsensor ISR re-enable interrupts while executing.
However, we still need to protect the epilogue of the ISR so that
the saved return address is not altered while returning.
We hoist the body of the function out of the isr in both cases for
clarity (and to avoid a stray return bypassing the lock/cli), so that
the re-entrant portion is clearly indicated.
This should fix the "STATIC MEMORY OVERWRITTEN" error messages randomly
happening when stepping at high frequency (where either isr is
preempted more frequently).
Factor-out MIN/MAXTEMP [BED/AMB] out of the error message, which is now
built at runtime instead.
Introduce two missing ultralcd functions lcd_setalertstatus and
lcd_updatestatus to handle regular strings.
246272 -> 246084 = 188 bytes saved
Partially revert 285b505c73a54e9af01816e3a614de73ad181851 so that
we ensure heaters are disabled ASAP in case of potential bugs
in the max_*_error functions.
Take advantage of the NTC thermistor found on the Einsy as an additional
safety measure, following the steps of the other MIN/MAXTEMP errors.
Introduce two configurable params AMBIENT_MINTEMP and AMBIENT_MAXTEMP
in the variant defines and set them for the MK3/MK3S to -30/+100
respectively.
AMBIENT_MINTEMP is primarily intended to catch a defective board
thermistor (to ensure MAXTEMP would be properly triggered) and thus the
trigger temperature is set just above the sensing limit and well below
the operating range.
AMBIENT_MAXTEMP is set at 100C, which is instead 20C above the maximum
recommended operating temperature of the Einsy. The NTC thermistor is
located just above the main power connector on the bottom of the board,
and could also help in detecting a faulty connection which can result in
rapid overheating of the contacts.
As for MAXTEMP, we cut power to the heaters, print fan and motors to
reduce power draw. Resume is not possible except by resetting the
printer, since the user is highly advised to inspect the board for
problems before attempting to continue.
In max/min_temp handlers remove the redundant disable_heater() call.
Handlers already need to call Stop(), which will disable all heaters
as the first step.
Fix comments in order to mention that all heaters get disabled.
Use "MAX/MINTEMP BED" correctly in both the LCD and serial.
Remove most of the original complexity from advance_spread.
Instead of accumulating time to be scheduled, plan ahead of time each
eISR tick using the next main interval + an accumulator (eISR_Err),
which keeps everything much simpler.
The distribution of the advance ticks is now using the real LA
frequency, which leaves a bit more time between the last LA tick and
the main stepper isr.
We take advantage of the accumulator to force a LA tick right after the
first main tick, which removes a +/- 1 scheduling error at higher step
rates.
When decompressing, we force 2 steps instead, so that the direction
reversal happens immediately (first tick zeros esteps, second inverts
the sign), removing another +/- 1 error at higher step rates.
If you're using flow to correct for an incorrect source diameter, which
is probably the main usage when using the LCD, then LA shouldn't be
adjusted.
It's still unclear what the effect of M221 in gcode should be regarding
overall extrusion width. If M221 means "thicker lines", then LA should
also be adjusted accordingly.
This stems from the fact that the source diameter/length needs to be
known in order to determine a compression factor which is independent of
the extrusion width, but the FW only ever sees one value currently (the
extrusion length) which combines both.
This makes it impossible for the FW to adjust for one OR the other
scenario, depending on what you expect for M221 to mean.
The e/D ratio should be calculated using the extrusion length.
As such, purify the e_D_ratio from the current extruder multiplier in
order to account correctly for flow adjustments.
Turns out for high-res curved models the numerical error and the
SLOWDOWN handling in the planner can cause enough variance in the
calculated pressure to trigger LA to continuosly, making matters worse.
Clamp LA again, but only during extrusion, so that the runaway error is
limited by the current segment length.
Add constants for the various required delays in tmc2130.h,
which will come in handy for stepper.cpp as well.
Move the delays in the _set functions and remove the pauses
from the various calling points and macros.
Note that the hard-coded pause wouldn't cut it for the stepper ISR,
but it's fine for other use cases.
Introduce new wrapper macros to tick the stepper pins.
Default to the original raising-edge stepping mode.
When using the TMC double-edge stepping mode (aka half-wave or
square-wave mode) the _LO macros become no-ops.
Calling plan_set_*_position should never be done without a sync, since
the current_position can be (and usually is) several steps ahead.
In retract() and inside the autoretract support, call st_synchronize()
prior to calling any of these functions so that we don't corrupt the
position of the backend!
When unretracting, split the Z and E moves in two steps so that the E
unretraction is not slowed down by the Z axis.
Fix the indentation of the affected code.
Before PR #2591 LA was automatically capped during cruising or
deceleration. However we now rely on reaching the current pressure state
exactly to stop. When dual/quad stepping inside the eISR we might incur
in oscillating behavior if we do not handle it correctly.
This might be the cause behind #2757
This now changes e_step_loops to be a phase-local variable, so we now
reset it each phase too (instead of per-segment).
When switching to a new trapezoid step with the right pressure, cancel
any pending eISR right away.
Similarly do not schedule another eISR if the pressure will be reached
by the end of the eISR.
This was done in the past to preserve the current LA_phase. This is not
needed anymore, since it will be reset at each trapezoid step when LA
is re-initialized.
There used to be a single stage where an extruder reversal could occur,
but since PR #2591 reversals can happen up to two times per trapezoid.
Reset LA_phase when ADV_INIT is set, since it is re-inizialized only
when needed a few lines afterward. This improves performance by avoiding
to check the phase continuosly to the end of the trapezoid.
Likewise, always set ADV_INIT during the first cruising step, also to
force a LA_phase reset.
PR #2591 made LA compression always account for retractions instead of
discarding the current compression steps. While this fixed overextrusion
in short segments followed by wipes, it uncovered another issue in how
the compression steps are spread during the trapezoid calculations
leading to gaps in segments followed by retractions (as highlighted by
/some/ prints in #2693).
LA1.5 always computes the required target compression steps for a
segment at nominal speed. Because of how the extra steps are allocated
using multiples of the accelerating frequency, if the segment is
truncated before cruising is reached, an additional cycle of steps can
be inserted before deceleration starts. Deceleration is also not
guaranteed to be symmetric where up to _two_ cycles can be skipped
depending on the stepping cycle, leading to a situation where a
symmetric acceleration/deceleration block will lead up to a cycle of
accumulated compression.
While forcing an the extra step during deceleration is possible by
tweaking the error term (eISR_Err), this doesn't guarantee balance in
all cases. The underlying issue is that the function is aiming a
compression which cannot be reached (nominal speed), and not at the
effective max speed reached in the trapezoid, thus moving the average
result higher over time.
We fix this by calculating the effective maximum speed (and compression)
reached during the trapezoid, which stops compression on the required
cycle irregardless of the error term, balancing the result.
This is the first unoptimized POC: this is not for production: a lot of
calculations are redundand and could work directly in steps/s^2.
This saves nearly all of additional FLASH usage of previous commit. It is only 70B worse than if no skipping is done in temperature compensation gcode G76.
There is no known purpose of this call.
lcd_temp_calibration_set() is switching on/off pinda temperature compensation from LCD settings menu (this is called "Temp. cal." on LCD).
st_current_init() does nothing on Einsy board, it enables and sets motor current selecting outputs on Rambo board (it used to be called digipot in history)

As pointed out by @leptun, with MMUs the combination of old/new filament
profiles in the same print is a likely scenario as we transition towards
LA1.5. Reset the detection state also with K0.
Move la10c_reset into finishAndDisableStepper, which is called in both
via lcd_print_stop() and indirectly via M84, saving some space.
M84 is checked-for to determine a complete file, so it's a superior
candidate to G80 (which some people avoid due to MBL issues).
Allow the LA 1.5 MAX value to be configured in Configuration_adv.h.
Define a customizable LA10<>15 detection threshold in function of the
above limit.
Clamp the result of of the LA10->15 return value to always
respect the new LA_K_MAX.

Handle uniformly compression & decompression at any stage of the
trapezoid.
Compared to before, this now enables LA compression also in the cruising
step (handling the converse of a chained wipe), as well as decompression
during acceleration.
Both of these can happen as a result of jerk moves, but are incredibly
rare. This is mostly needed to allow rapid decompression directly at the
acceleration step during travels between a retraction&deretraction.
We also check for the pressure level in a single place, reducing code
size as well as disabling LA earlier when not needed for the rest of the
block.
Perform the check one step earlier, avoiding 32bit overflow for very low
compression factors.
Fixes#2566 (although for K15 to have effect the conversion probably
needs to be adjusted on the low end)
LA assumes all the nozzle pressure is released at the end of each
extrusion, which makes calculating the required pressure advance during
travels and retracts not normally necessary.
This is not always true in our planner, since the E axis is explicitly
ignored when not in use, but also due to E-jerk allowing a non-linear
jump in speed. And since the compression factor is currently tied by XYZ
axes and not independently calculated, this can result in a wrong
estimation of final pressure in several conditions.
To avoid overburdening the planner, change the underlying assumptions
about backpressure:
1) Pressure is no longer lost when LA is disabled: if a retract is
followed by an unretract of the same length, the pressure will be likely
maintained entirely. This also holds true during travels, as long as the
retract length can overcome all the backpressure (which is the case in
all but the most noodly materials)
2) Pressure is released as soon as possible during travels: we now
enable LA also during travels, but under the sole condition of undoing
excess pressure.
We do that by checking for backpressure at the start of any segment
without an acceleration phase that doesn't have any E-steps (a result
which can happen due to the above). If pressure is not nominal, we run
the extruder in reverse at maximum jerk as long as the segment allows
us, since proper acceleration would be prohibitive at this stage. As the
pressure difference resulting by the above is still _very_ low, any wipe
or short travel will be able to equalize the nozzle pressure *before*
extrusion is resumed, avoiding ooze.
In the current code we initialize the LA state on-demand already at the
right step, which makes keeping track of the tick position no longer
necessary.
Make the advance ISR almost stateless by removing the last vestiges of
the original implementation and introduce a single target pressure. This
will be needed later in order to trigger the LA isr inside the cruising
phase.
I forgot to change also the
- `#ifdef DEBUG_DCODE_3` to `#if defined DEBUG_DCODE3 || defined DEBUG_DCODES`
- `#ifdef DEBUG_DCODE_5` to `#if defined DEBUG_DCODE5 || defined DEBUG_DCODES`
in the `Dcodes.h` file which I added to `Dcodes.cpp`.
Due to this issue the "Debug" version fails during compiling.
Sorry for that.
