Duet3D 6HC + Toolboard missing filament on curves
-
Reducing the print+retraction speeds I'm able to print w/out lost messages on 3.3 alpha. My extruders are on my 3hc expansion, and the filament depositon was the squiffy part of all of my lost prints, whether it be for some reason jamming constantly with known good settings ( I run identical extruders on different platforms w/out issues with same settings/filament) or getting the kind of gaps/curves that are shown here.
Going to run a longer, toolchanged print to see if there are still issues.

@jbarros, please try the latest unofficial 3.3beta main and expansion board firmware. It solves all the issues we are aware of except for a very slight reduction in actual vs. requested extrusion.

@dc42 I just did a test with another part that was giving me trouble before and it looks way better (see the nut inserts on the top right).
I do notice some ringing that was not so pronounced before (see the round middle part).I am using DAA which you say was the culprit:
M593 F50.0 ; cancel ringing at 50.0HzCan I assume the "fix" also reduced some of the DAA "power" ?

ohmy I thought I was going insane until I saw this post.
I thought it was a problem with my extruder motor or the extruder itself... or the filament tensioner... I went ahead and recabled everything and twisted the CAN data wires, added ferrite bead... thanks god I saw this post before I rebuilt my printer all over again
This is just to say that I'm experiencing the same issue with a toolboard.

@matt3o I too was going crazy for a while thinking I had slicer setting issues or something but it ended up getting worse and then I saw another thread with CAN issues on an expansion board and I started to be suspicious
You can try the beta firmware here:

Note: you have to upgrade both 6HC and 1LC -

Probably will need to but didn't want added variables now

No, the fix didn't reduce the effectiveness of DAA.
The bug was an oversight when I implemented DAA. Adding DAA meant that the deceleration of a move was no longer always the same as the acceleration; so I introduced a new deceleration move parameter, and I went through the code changing "acceleration" to "deceleration" where required. At that time, CAN support was experimental and not released. Unfortunately I was using a standard build configuration without CAN support when I made the change for DAA, so the "find all references" command in Eclipse didn't pick up a reference to "acceleration" in the CAN-specific code that should have been changed to "deceleration".

Per your previous comments, rounding issues?
Do you know the loss % and do you believe it's fixable? -

Do you know the loss % and do you believe it's fixable?It was well under 1%. I think one user reported it as 0.18%. I've already fixed it for the case that pressure advance is not in use.
