Issues with servo on Tool Changer after firmware update 3.1.1

[qablos]

I've got the servo moving again, but I am getting a lot of crashes - haven't managed to start a print yet. Seems to a infrequently crash and reset when a macro is called (not always the same one) with " Lost connection to Duet (Board is not available (no header))". Also had it mention the transfer ready pin a couple of times - I've checked the ribbon from my pi4 to the duet.

My status is stuck on "Changing tool" at start up which is odd - calling a T-1 sets it to idle.

If you think the Duet is crashing and resetting, next time it happens run M122 and post the report here.

Also just got:

[RobMink]

How are you powering the servo? On my tool changer I have a separate 5v bus for things like the servos so that they don't overdraw from the duet 5v bus. My RPI4 sometimes indicates a low power situation with JUST it and the duet, no usb in the pi, no servos or other 5v draws from the duet 3 board.

[dc42]

@qablos, thanks for posting that diagnostic data. I'll take a look at it tomorrow.

[qablos]

Just posting this here for context.

The problem is currently occuring during homing the machine. This is not to say that it is exclusive to homing, just that is about all I can try to do right now. Running homeall.g then sending T0/T1/T2/T3 also makes the duet reset.

Scenario 1:

Called homeall.g below first time, it ran fine. Called it a second time and the duet reset.

Thanks, that 3 different types of failure you've posted now, probably related in some way.

I've been looking at the first one and it seems to be caused by the Z probe not being found when expected. [EDIT: so is the third one, it's the same failure at a different program location.]

Please post your config.g file.

[dc42]

If you disconnect the servo, do you still get the crashes?

@dc42 Just tried this:

Running homeall.g once worked. If I tried the second time, instead of the duet crashing it seemed fail to stall detect and crashed to the y hard limit. This happened again when I connected the servo again.

Next time the duet crashed with after running homeall.g twice as before. Seems to mostly crash the duet, sometimes it fails to stall detect:

@qablos said in Issues with servo on Tool Changer after firmware update 3.1.1:

Running homeall.g once worked. If I tried the second time, instead of the duet crashing it seemed fail to stall detect and crashed to the y hard limit. This happened again when I connected the servo again.
Next time the duet crashed with after running homeall.g twice as before. Seems to mostly crash the duet, sometimes it fails to stall detect:

Please clarify: what exactly happened when you ran it with the servo disconnected? Did you get no firmware crash, but the stall detection failed?

The semi-random nature of the fault reports makes me suspect that the issue is to do with the power surge drawn by the servo. That is why I wanted you to try it without the servo connected, to see whether you still get any firmware crashes.

What model of servo is it?

Only head crash was with the servo disconnected.

Servo model is: Hitec HS-70MG supplied on the original beta30 tool changers https://www.servoshop.co.uk/index.php?pid=JP2212122

@qablos [EDIT, previous being flagged as spam]: Only head crash was with the servo CONNECTED, 1/3.

Overall it seems to be largely irrelevant what I'm doing, just playing about with G1 moves and after <10 moves it resets, sends:

"Warning: Lost connection to Duet (Timeout while waiting for transfer ready pin)"

I'm not sure if it's something I've missed on an update note, I've tried my best to read through and can't see anything when I updated but I was upgrading from 3.01 RC5 as I'd had a series of work going on that I didn't want to interupt. I've returned to 3.01 RC5 and dependencies for now and so far everything is working.

[EDIT: I will happily update again if you want me to test anything]
