@T3P3Tony @chrishamm
thank you for the fix! it is now working as expected!

@T3P3Tony I will test these first opportunity I can. Current eta is Monday

@Gamefanatic3D please will you test with 3.6beta3:
https://forum.duet3d.com/topic/37289/software-version-3-6-0-beta-3-now-available

@Argo Beta 3 is now released:

https://github.com/Duet3D/RepRapFirmware/releases/tag/3.6.0-beta.3

@NikA @resam I already identified and fixed this problem a while ago. A bug fix will be part of the next beta.

@Bendy88-0 Thanks for your report. I've highlighted it to @dc42. I've upvoted your comment, which should allow you to post images (it's a spam deterrent), should they be needed.

Ian

@dc42 Thank you for the update. I will wait for the next release.

@Paski to confirm for anyone else reading this following our email exchange:

That backlash is too high for successful calibration where the encoder is being used for motor commutation. There is inevitably backlash in a system where there is a coupler and then a leadscrew between the motor and the encoder. Using an encoder on the motor is effectively required for a well behaved system, adding a second encoder on the axis for position loop closing is supported but that can't be the only encoder.

Also, depending on axis length, and the position of the 1HCL, the SPI cable may be too long to be reliable, although thats not the specific issue in this case

Hi @dc42,

I was running in standalone mode.
Thanks for the "M409 K"boards[1].drivers[0].closedLoop" command; it revealed an incompatibility with the DWC, which was resolved after an update.

BR.

@ketirange Turns out a motor connector and cable was faulty, and after replacing it im able to perform a calibration move.

@DaveA @Leonard03 its been fixed in source and will be part of beta 3

@Leonard03 thanks for your further feedback. We have changes to PanelDueFirmware and RRF already made to reduce the interaction of PanelDue and DWC and we will release these soon.

@leone thanks again. Looks like the maximum allowed acknowledge delay should be about 900 to allow for maximum length messages. However, I'm still a little surprised that you had the maximum delay exceeded 10 times in succession.

@dc42 Yes, it is a Duet 2 Wifi board.
