Cold Extruding After M302 P0
-
Hi there! I have a Voron with a MB6HC Main Board and a 1LC Toolboard. I seem to be able to extrude and retract via ...
G1 E1 F1500... after starting the printer. It will also extrude and retract after posting ...
M302 P0If I post ...
M302... I get ...
M302 Cold extrusion is forbidden (use M302 P1 to allow it), min. extrusion temperature 160.0C, min. retraction temperature 90.0Cbut it will still extrude even though current extruder temp is 22 deg C.

Firmware version?
-
@Phaedrux Firmware is 3.4.6 on the main board as well as the toolboard.
-
Im not sure if this has anything to do with this issue, but Im also able to move, for instance ...
G1 X345 Y345 F6000 H1... even before I have homed any axes. It moves to the far right corner, as requested, and stops when it gets to the first of the two X, Y, endstops. Calling M564 shows ...
M564 Movement outside the bed is not permitted, movement before homing is permitted.I honestly forget if this was how it has worked in the past, and I apologize if this is normal behavior.
-
A move with the H1 parameter is used for homing one or more axes - so naturally it has to ignore the homed state of the axes.
As to M564, it takes an H and/or an S parameter. The H determines if moves on un-homed axes are allowed. The S determines if moves outside of the min/max limits are allowed.
With no parameters it simple reports the current state.

@fcwilt Okay, that makes sense regarding the H1 parameter. And I apologize if I wasn’t clear regarding the M564. I was just calling that to show that I wasn’t allowing moves outside of the build volume.
I’m still confused regarding cold extruding though. In my printer running a Duet 3 mini with no toolboard, the same cold extrude command gives me a warning/error, which is what I would expect.
-
@Charlie see here https://docs.duet3d.com/en/User_manual/RepRapFirmware/CAN_limitations
Cold extrusion prevention is not enforced on extruders driven from CAN-connected expansion boards. We expect to remove this restriction in firmware 3.5. -
Got ya.
In general I keep the restrictions on moving un-homed axes and moving outside the min/max limits in place and only change the settings in certain limited cases and restore the "normal" settings as soon as possible.
