@dc42 yeah it is only ever the bottom sensor that exhibits that behavior. I am fairly confident my connector crimps are good as I have tried to shake/shimmy the harness around while heated and attempted to recreate the readings but they were stable. I just hate that the problem is so inconsistent and hard to replicate. I will start by replacing the sensor and double checking my connections on both sides and see if that fixes the issue.

@t3p3tony No I only have a single part on the build plate, albeit a large one. I will upgrade to 3.3 and see if that produces similar error messages.

@r3d, this is now fixed in the 3.3beta source code. I have put a binary at https://www.dropbox.com/sh/oxyezimiusnosxa/AAAgjLNKuTL8oEcXgihZqojXa?dl=0.

@R3D said in Toolboard Stepper Driver mapping:

....................and all of the motors driven by the tool boards are using sensorless homing.

Just spitballing, is there a way to force a tool as active without running the tpre#.g files?

Well this is definitely going to be a game changer for me, I will have to do some testing on one of my other test rigs to play around with this.

Thanks a million @OwenD, I am constantly amazed on how helpful the Duet Community is and i hope one day I know enough to be able to help others out as you have helped me.

The XYZ axes M584 is correct, but M92, M566, M203, M201 it is not possible to define multiple Z values. XYZ values are defined for those M G-Codes per axis, only one value each. Only for the extruders multiple values are allowed, because the are interpreted as if they are separate axes. deckingman explained it nicely, but I cannot find the link in the forum.

Wiring stepper (stepper disconnected from the driver!): there is a simple method to find the pairs: keep all 4 wires separated, turn the shaft to find out the torque force. Then short two wires and if you cannot turn the motor any more, they belong together. You cannot find out the rotation direction with this method, however.

Works, Thanks a million @dc42, now on to calibration.

@droftarts Well it will definitely be one of my first places to check from now on XD
