Unofficial 3.4 Maestro Beta: Extruder Drive Issue

[CCS86]

Hey @dc42 I just flashed the unofficial beta build to give IS a shot on my Maestro, but didn't get to test it yet.

With IS and PA disabled, it was evident that the extruder drive wasn't functioning correctly. Even my prime line misbehaved with a pulsing extruder action, and high pitch whine from that stepper. Once the print started (a simple spiral vase square box), it continued to make high pitch "chirpy" sounds from the extruder stepper, and didn't push much plastic at all.

Stepper analyzer shows some definite weirdness:

M122 below. Let me know if I can gather anything else useful for you.

@ccs86 what pressure advance setting are you using?

@ccs86 what pressure advance setting are you using?

Zero at the moment.

Here's my full config:

@ccs86 I think i hit the same bug but on a duet2 wifi running the latest beta. It seems that high pitch is starting when printing lines considered "bridges" from prusa slicer at the first layer that was at 0.13mm (variable layer height print). Also i notices some more clicking on other test print i was doing as per previous beta build. I get nothing when issue M122 on that firmware.

Awesome, working beautifully so far!

Very simple first test: 30x30x30 square, 3 perimeters, 80 mm/s, 10k accel, 12 jerk

All shapers seem highly effective at cancelling the ringing. But all visibly slow the effective acceleration a lot and cause significant corner bulge. I would love to be able to just tune that out with PA, but have found the current implementation very ineffective on my bowden printer.
