@supertb1 worth a shot

[lirwin17]

Hi @supertb1,

Sorry, I'm not 100% clear on the actual issue here. Thanks for providing your M122 output, from tuning error: 0x1f, it seems like no runtime tuning has happened. Similar to when an axis is un-homed, a driver that is untuned will not move, so if the issue is that the axis isn't moving then that would be the expected behaviour in this instance.
However, if you have run tuning, there is a deeper issue here.

Details of tuning can be found on this page. Specifically, the two 'what do I need to do?' sections (1, 2) are compulsory before the system will move (eventually these should be part of the online config tool, but not just yet for the beta test)

If you weren't aware of this page in the docs, that's really useful for us to know because it tells us we need to draw more attention to that page

Thanks!
Louis

[supertb1]

@lirwin17 and it fails to manually tune

[supertb1]

@lirwin17 with just raw encoder reading and step maneuver it throws fault: M569.5 P50.0 S500 A0 R0 D1 V64 and maintains that the motor is not in closed loop mode

[supertb1]

@lirwin17 with just current motor steps and target motor steps selected performing the step maneuver yields: M569.5 P50.0 S500 A0 R0 D6 V64 and maintains that the drive is not in closed loop mode

[T3P3Tony]

@supertb1 i think you first need to tune the motors

M569.6

as outlined here:
https://duet3d.dozuki.com/Wiki/Tuning_the_Duet_3_Expansion_1HCL#Section_Tuning

If you are using a quadrature encoder (i.e. your M569.1 command includes T1 or T2), then from the table above, manoeuvres 1, 2, 4, 8 and 16 are required - this means that they must be run every time the printer is powered on. This can be achieved by using the following command:
M569.6 P##.# V31 ; Where P##.# is the driver address to tune

[lirwin17]

@supertb1
Hmm there are are a few M122 outputs so I've lost track a little...

The first ones show Closed loop enabled: yes, but then some later ones show no.

The problem seems to be that when you come to run the tuning move, that yes has flipped to a no...

Please could you run through the following:

• power up (so config.g runs)
• run a manoeuvre command - it might be best to start with the simplest one V1

And at each point check M122 to see when yes flipps to no. Is it showing yes after config.g has run, or is it only when the move is run that it flips to no?

[supertb1]

@lirwin17 That yes to the closed loop enable was there before I updated the 1HCL board to the latest firmware and now at power up it reports "no" to the close loop enable
