The PINDA temperature compensation is defined for values above 35C. To achieve an optimal first layer consistently it is vital to start the print with a temperature of >= 35C on the pinda probe.
When doing a manual pinda temperature calibration it is necessary to begin homing and mesh bed leveling at an exact temperature. This gcode is perfect for this.
Example startup code:
G28 W ; home all without mesh bed level
G0 Z50 ; raise Z to not heat PINDA before bed is warm
M104 S215 ; set extruder temp
M140 S60 ; set bed temp
M190 S60 ; wait for bed temp
M109 S215 ; wait for extruder temp
G0 X50 Y50 Z0.15 ; this is a good PINDA heating position
M666 S35 ; the new code - wait until PINDA is >= 35C
G28 W ; home all without mesh bed level
G80 ; mesh bed leveling
See my forum post later for more explaination on my manual temperature calibration procedure. I will link it then.
numeric accuracy and to reduce compuatitonal load. With this commit,
the numeric rounding is fixed not only for the M221 G-code
(as implemented by the preceding commit), but also for the volumetric
extrusion in general.
Removed the old FILAMENT_SENSOR code, which served the purpose
to modulate the volumetric multiplayer in real time depending
on the measured filament diameter. This feature will certainly not be
used by Prusa Research in the near future as we know of no sensor,
which would offer sufficient accuracy for a reasonable price.
dcode D12 removed (no longer needed)
homeaxis optimized + xy home calibration support
new eeprom variables
new lcd menu edit types (byte3, mres, wfac), new menu "Experimental"
currents adjusted
or DISABLE_STEPPER_DRIVER_INTERRUPT().
If this is not done, the stepper interrupt would likely overflow,
leading to a maximum 32ms delay before the stepper interrupt wakes up.
In addition, the stepper timer overflow error would be reported
by the debug builds.
A build version and repository is displayed on the welcome screen,
D-codes, stack overflow check and stepper timer overflow check
are enabled in the debug mode.
