I wanted to say thank you that solved my extrusion issue. Thank you very much!

@ObiJohn damn I missed that in the docs yes i had the allow cold extrudes command in the config. I have commented it out so we shall see. When I was trying to extrude I was at temp 195c on the extruder. but we shall see

Hello all I updated from 3.4.5 to 3.5.0 b2. I have a duet 3 6hc with a toolboard 1lc connected via can at address 121. after the update i can no longer extrude from the toolboard connected stepper. if i revert back to 3.4.5 it will work again. I am also haveing issues with both versions stopping in the middle of a print saying it is finished when it has only done a very small part. what do you need going forward to fix these issues? here is the M122 and the M122 B121

M122 diagnostics has no outputnot sure if this is a dwc issue or a firmware issue. Any help would be appreciated

@dc42 I was wondering is it possible to get finer adjustments in current. Part of the issue with a 4 into 1 nozzle is the 4 motors need to be balanced. If the balance is not correct you get unpredictable extrusion. The better the control over the current the more accurate the extrusion balance
