[3.4.0rc1] cold extrusion not prevented
-
Hello folks,
I think I have found a bug in the current 2.4 release candidate: cold extrusion is not prevented.
M302 gives the following result:Cold extrusion is forbidden (use M302 P1 to allow it), min. extrusion temperature 160.0C, min. retraction temperature 90.0CThe extrude- and retract-buttons in DWC are grey as they should.
However, when i send "G1 E10" or use PanelDue the extruder turns perfectly fine - but it shouldnt with the hotend at 27°C!Here is my Config:

@marvineer cold extrusion prevention doesn't currently work on extruders drive from CAN-connected expansion boards. https://docs.duet3d.com/en/User_manual/RepRapFirmware/CAN_limitations

Thanks, seems I have missed that! I guess I will take that as "i have done something wrong" - until version 3.5
