Issues after upgrading to 3.5.4 | Duet2wifi

alil2096

Hi All,

yesterday I've ugraded my Duet2 wifi from 3.2.x (i think, I don't remember the correct version), to the last stable release, the 3.5.4.

After that, I 've a lot of problem:

fans don't work. Before the update I was using one always on fan for cooling the heatsink (using one of two pins always on) and one fan for cooling print on fan0 pin. After update no one is working. I've partially resolved wiring the always on fan directly on the power supply (24V); for the second fan I've tried to change the pin (from fan0 to fan1 and fan2), but none of them work.
Z probe issue: after the change my probe doesn't work well. The pritner start to print with about 1mm of air between the nozzle and the heatedbed. I've tried to recalibrate, but I haven't solved
z motor: my printer is a custom coreXY, and I've two motor nema23 for z-axis. After the update it seems that the motors do not have enough power to raise the plane, but I have not changed anything in the firmware or hardware. The motors now act as if they are delivering little power

Here my config.g:

I disabled the fans now and put the Z probe value back to 0, but then I wanted to try and it gave me the motor problem. They are not warm and until yesterday work well.

Any ideas?

Thanks,

Please send M122 and post the response.

For the fans, I can't think what would stop all the fan outputs from working other than the fan fuse blowing, or the jumper that sets the fan voltage being removed. Did you use the fan voltage jumper to jumper the erase pins, to flash the firmware, and perhaps put it back in the wrong place? See the wiring diagram https://docs.duet3d.com/Duet3D_hardware/Duet_2_family/Duet_2_WiFi_Ethernet_Hardware_Overview#wiring-diagram and check 'V FAN JUMPER SELECT'.
What kind of probe? You have inverted the probe in your current config.g. What value does the probe report in DWC? I don't know what has changed with probing between 3.2 and 3.5 (something may have done) but if the probe is reading correctly, try just recalibrating the G31 Z offset. See https://docs.duet3d.com/User_manual/Connecting_hardware/Z_probe_testing
Your speeds on Z are quite high, particularly Z jerk (M566). Are the Z motors turning a leadscrew? Older RRF versions may have been limiting this. Try M566 Z20, and work up from there. You may also need to reduce the Z speed (M203) and acceleration (M201).

Additionally:

You have a number of lines in config.g that refer to a 'U' axis. Remove the U parameter from the following:

M350 Z16 U16 E256:256 I1							; configure microstepping with interpolation
M92 X133.33 Y133.33 Z640 U640 E6550:6550			; set steps per mm
...
 
; Axis Limits
...
M208 X370 Y330 Z398 U398 S0							; set axis maxima

You are running the extruder at x256 microstepping. Most likely, changing to x16 microstepping with M350 E16:16 and changing steps per mm to M92 E409.375:409.375 will offer no reduction in print quality, while dramatically reducing the time the MCU has to spend calculating extruder stepper pulses.
