Auto Calibration Problem With Bed.g
paul12 last edited by paul12
I have set up a new delta printer, but while printing a large object the print does not stick to the build plate.
I have tried changing the H parameter in the Bed.g , but it does not seem to have any effect on the auto calibration.

; Use S-1 for measurements only, without calculations. Use S4 for endstop heights and Z-height only. Use S6 for full 6 factors
; If your Z probe has significantly different trigger heights depending on XY position, adjust the H parameters in the G30 commands accordingly. The value of each H parameter should be (trigger height at that XY position) - (trigger height at centre of bed)
M98 Pretractprobe.g ; retract mechanical Z probe
Some point stick perfectly while some wont, i tried giving very larde values for H , but no change is happening after auto calibration.
There is a known bug in current firmware: if you have deployprobe.g and retractprobe.g files then the H parameters on G30 commands don't work. This will be fixed in firmware 2.02RC4.
Btw you should not call deployprobe.g and retractprobe.g explicitly with M98 as your bed.g files does, because they are called automatically.
So, can i revert to a previous version of the firmware to rectify the problem?
I will change the deploy n retract setting in the bed.g.
Also sir when will the firmware 2.02RC4 be available?
anyone please do help me. what should i do to correct the error?
@DC42 sir this feature is still not available?
Yes I fixed it months ago.

does Firmware Version: 2.02(RTOS) (2018-12-24b1) has the fix? It doesnt seem to work for me.
Yes, it includes that fix.
