You're not the first to notice after an update.

aha, seems to be working here it's calibrating now!

Caveman

Nope not fixed, after reboot same issue.

Did you save your calibration with M500?
Do you also have M501 at the end of config.g to load the saved calibration?

I think i figured it out, it has active high endstops and that also changed in rff3.
changed endstops fron x1 y1 z1 to x2 y2 z2 and now everything works as normal also the 5mm moves

; Endstops
M574 X1 S1 P"xstop" ; configure active-high endstop for low end on X via pin xstop
M574 Y1 S1 P"ystop" ; configure active-high endstop for low end on Y via pin ystop
M574 Z1 S1 P"zstop" ; configure active-high endstop for low end on Z via pin zstop

Ah yes, your endstops were set as min endstops. For your delta the endstops are at the top, ie the high end. so X2 Y2 Z2 would be correct.

And how do I set new F value for fans? have delta fans and in my old config I had M106 P0 S0 I0 B0 F6500 H-1 for partcooling fan.

Now it loosk like this M950 F0 C"fan0" Q500 ; create fan 0 on pin fan0 and set its frequency
M106 P0 S0 H-1 ; set fan 0 value. Thermostatic control is turned off

Change the M950 Q500 to Q6500.
M950 Q is the frequency now

M950 is an important command in RRF3 as it defines pins now.

thanks just found it on the duzoki

Have another question, after calibration and everything saved and M501 in config. Do I have to calibrate everytime a reboot delta? Or can I just run a mesh?

Phaedrux

I'm not a delta user, so I can only defer to these links.

but from what I gather It's not uncommon to run a quick calibration before every print.
