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).
