Extrusion/Retract by button results in never ending "busy"

[mmueller70]

Hello!

Today I updated my Duet2Wifi with Extensionboard and Paneldue to the latest Firmware 3.5.1

Everything seems to work fine, but whenever I want to extrude or retract by pressing the button on webcontrol or paneldue, the result is a "busy" and nothing happens. Only reaction: the requested speed ist set on webcontrol. nothing else happens.

My tools are using 2 drivers simultaneusly for extrusion - one in filament changer, one as main extruder. I also tried configuration with only one driver per E-axis, but the result is the same.

Sending an G-Code like "G1 E2 F100" works.

Any hints?
Greetings,
Markus

@mmueller70 I suspect that the very high extruder acceleration you have configured in your M201 command has triggered an issue in RRF 3.5.1 that we have fixed in the forthcoming 3.5.2 release. Try reducing extruder acceleration.

Thanks, that worked!

@mmueller70 I'm glad it worked. We've now released 3.5.2-rc.1 in which this bug has been fixed.
