// la10compat: LA10->LA15 conversion
|
||
|
|
//
|
||
|
|
// When the current mode is UNKNOWN autodetection is active and any K<10
|
||
|
|
// will set the mode to LA15, LA10 is set otherwise. When LA10
|
||
|
|
// compatbility mode is active the K factor is converted to a LA15
|
||
|
|
// equivalent (that is, the return value is always a LA15 value).
|
||
|
|
//
|
||
|
|
// Once the interpretation mode has been set it is kept until the mode
|
||
|
|
// is explicitly reset. This is done to handle transparent fallback for
|
||
|
|
// old firmware revisions in combination with the following gcode
|
||
|
|
// sequence:
|
||
|
|
//
|
||
|
|
// M900 K0.01 ; set LA15 value (interpreted by any firmware)
|
||
|
|
// M900 K10 ; set LA10 value (ignored by LA15 firmware)
|
||
|
|
//
|
||
|
|
// A LA15 firmware without this module will only parse the first
|
||
|
|
// correctly, rejecting the second. A LA10 FW will parse both, but keep
|
||
|
|
// the last value. Since the LA15 value, if present, corresponds to the
|
||
|
|
// truth value, the compatibility stub needs to "lock" onto the first
|
||
|
|
// seen value for the current print.
|
||
|
|
//
|
||
|
|
// The mode needs to be carefully reset for each print in order for
|
||
|
|
// diffent versions of M900 to be interpreted independently.
