I haven't been able to conrrectly configure stall detection for the extruder, I just found this post from some years ago https://forum.duet3d.com/post/102570 so I'm running out of options if CoolStep can't be implemented...

I went over electronics compartment last weekend and couldn't find anything obvious like a loose wire pressing reset button or some shorting on the button itself. Electronics are cooled by fans which are always on which may be enough - but I'm not sure on that one

@droftarts Thanks Ian, I will mess with the pin and see if that does anything. I also have a cr touch and knockoff bltouch at home I can test out or swap the pins from.

@Sazabi Did you try to run the BFTouch using Z_Probe_In in analog mode? Then, you can call deployprobe.g in plain air and actuate the pin manually. Since DWC monitors the analog value in ”Z-Probe” (range 0 - 1000), you get an idea what to chose as your trigger level.

Here’s a snippet from my config.g, your values will be different. The trigger level is set with the P value in G31:

; Z-probe: M558 C"zprobe.in" P1 F200 T10000 H5 A9 S0.003 R0.0 ; mode 1 (analog in), F=probing speed, T=travel speed, H=dive height ; A=repetitions, S=tolerance, R=recovery time G31 T1 P500 X0 Y9 Z1.30 ; configure probe physics; P=trigger value, X/Y offsets, Z=probe offset ; NOTE: less Z-offest = nozzle higher above bed

@3DPMicro I notice you've connected 'en' enable. These drivers are usually enabled by default, and it's possible you're actually disabling it by connecting to 'en'. I recommend checking the TMC5160 documentation to see what signal the enable is expecting, along with what the other CFG pins do in standalone mode.

Yes, a picture of the back would be useful, assuming they've got it correct!

@dc42 said in Struggling with PID tuning on Duet 3 with custom CoreXY:

You can configure heater feedforward to combat that.

I think I figured it out. I had B0 instead of B1 in my M307 line. Seems to be working as it should now.

@bug2k22 I didn't read your post carefully enough and I thought you meant the FFC for the inductive sensor. The FFC for the filament monitor is less critical. You can route it close to metal if necessary, preferably metal that is connected to Duet ground.

@MaxGyver I would use unshielded twisted pair in that situation because it has lower capacitance. If you use shielded, I suggest you connect the shield to Duet ground and leave it unconnected at the driver end of the cable.

Additional ESD protection should not be required.

Thank you both! I'll have an engineer do some testing on it. We've never seen one have this kind of issue before and would like to understand if we (really, myself since it's been on my desk) caused it damage or if it was just a faulty board. I'll go ahead and remove the "Unsolved" tag.

@Aubertin the 3.3v regulator is U10 which you said was getting hot

@JC42 i've used a similar servo and MG90s on a toolboard. I used a buck convertor off of the 24v input to get the 5v the servo required.

Various details about servo's buried in my SV08 thread - starting about here if they are of any use.

I presume you have already seen the standard duet3d docs on hobby servo connection.

@vaike_peeter thanks for your report. I have identified why re-initialising the probe when it was already taking readings caused a reset and I have implemented a fix for that.

just in case OP is still interested: I posted my working config here

@dc42 perfect, thanks a lot! I think the topic can be closed then.

@crap you may want to check and/or re-crimp the connector at the Duet end of the cable, and make sure the pins are fully inserted. Also check that the soldering of the connector on the Duet looks good.

@gloomyandy

Yes, indeed there are.

I was speaking from my personal experience BUT as I have no intention of using the SZP for setting the Z=0 Datum, I have done no testing of that feature.

I'm "old school", I install BLTouch units for setting the Z=0 Datum.
