What happened?

Setting minimum feed rate with M203 to M203 I0 results in minimum feed rate set to 0.6mm/min
Sending movement command eg G1 X1 F1.5 results in no movement and firmware stuck at 'Busy'.
Requested speed is also shown as 0 in Object Model and DWC.

try setting a non zero value like 0.001 as a workaround, does that help? Gesendet von Proton Mail für Android

@oliof No. I tested with M203 I1 too. Any value for I below 0.6 and M203 is set to I0.6.
