@Phaedrux Thank you for the help. Now I run as many times as I want, even with the Input Shaping plugin. No more crashes!

@fcwilt Did that now and discovered the issue. Yet another poor crimp by me. It threw me off since it worked the first time I tested it. Now the heater works

@oliof
I understand. It's barely visible, as tiny black hole. Was under the impression that it would be white.

I guess they decided to mark it with the white dot above the chip, on the PCB instead.

@fcwilt @droftarts Yes exactly. Was able to fix by doing another delta calibration (and saving it) after doing the steps you both mentioned. Z0 is now correct. Will try to do another print now.

@Velvia

Do I understand it correctly? Thanks for all the help @oliof

@fcwilt @droftarts
Thanks for all the help!

@droftarts

Thank you! It worked. Now it's:

M308 S10 Y"mcu-temp" A"MCU"                        ; MCU temp on temp sensor 10
M950 F1 C"out6"                                    ; create fan 1 on pin out6 and set its frequency
M106 P1 S255 H10 T30                               ; set fan 1 value. Virtual thermostatic control is turned on, turn on and off
M912 P1 S-10.8                                     ; MCU temperature calibration

@deckingman That was the issue. Huge thanks!

@deckingman Didn't catch that! Will change. Thanks!

Identical gcode from one day ago works fine. Only difference now is that I updated Prusa to 2.6.0. Otherwise everything is the same.

Can I run separate input shapers for different tool heads? For example M593 P"zvddd" F47 for T0 and M593 P"mzv" F42 for T1, if I put them under each specific tool in the config file?

@T3P3Tony It's a 24v bed. It says it's a 120w bed, so 5 amps? Have not tried higher frequencies than 300

@infiniteloop It's definitively the bed. It's from where the cables are soldered to the bed.

@achrn Thanks for the input. I guess I'll just have to live with the low clicking noise from a low PWM.

@infiniteloop I did. I've tried everything between Q2 and Q300. Nothing helped, just changed the tone of the noise. However the low "clicking" sound from Q10-20 is better than the singing/whining from 100+

Using M307 H0 B1 still causes it to make the sound. Can I use Q parameter (PWM) at some really high value? Like over 20k so I don't hear it?

@achrn Is there a solution I can use in RRF?
