Duet 3 + Tool Board Extruder/Retraction Issue

@dc42 said in Duet 3 + Tool Board Extruder/Retraction Issue:

If you are running tool board firmware 3.1, then it could be that you are getting hiccups on the tool board (which you can check by doing a M122 report for the tool board). If that is the reason, then upgrading the tool board firmware to 3.2beta1 should fix it.

It looks to me that it's retracting, but retracting too late in the game. this could explain the blobs at the end of the line and under retractions on the middle of line. Tool Board does reports hiccups constantly.

I will gladly upgrade the firmware to the latest beta if I can do it safely from the DWC. If it fails, I would most likely have issues with recovery.

Why so many blocked and suspended CAN bus messages?

In future can you copy and paste the text of the M122 rather than a screen shot?

Sorry, here we go.

So you are getting a lot of hiccups on the tool board, so perhaps try the new beta?

is 7mm/s correct for your retraction speed?

Retraction speed is 7 mm/s, any value higher that that was performing extremely worst when stepper connected to the tool board.

I didn't install beta yet. I'm willing to do so, but a little confused in the instructions for installing unstable version using SBC and DWC.

What about bunch of blocked and suspended CAN bus commands on the Duet3 board itself?:
CanReceiv(suspended,3388) CanSender(suspended,1392) CanClock(blocked,1436)

Those do not refer to messages. The clue is the "Tasks:" label at the start of the line.

Can you please point me to how to update to latest beta? What files do I need to download update DWC (looks like it's required for new beta) what bin files do I need to update Duet3 and tool board?

I'm looking at this guide right now:

This is for a specific case for updating to 3.0 final from 3.0 beta 12.

To update to the 3.2 beta2 using a SBC you can add the unstable repository on the pi and then use sudo apt update sudo apt upgrade as usual.

@evomotors
Do you still face the same issue in extrusion ?
I'm planning to drive extruder from other board too.

Phaedrux

@user3d I believe all tool board extrusion issues are solved in recent firmware, though the firmware version must match between mainboard and toolboard.

Not toolboard. I'm planning so with EXP1XD
@phaedrux is it recommended?

dc42

@user3d I am not aware of any issues using a EXP1XD to drive an extruder. The EXP1XD and the TOOL1LC use common source code, so the issues we fixed for the tool board are also fixed for the EXP1XD.

User3D

@dc42 ok. Thank you
