@timschneider, many thanks for your thorough testing and for diagnosing the cause of the problem. I'll mark https://github.com/Duet3D/RepRapFirmware/issues/927 as fixed in 3.5. If/when we release 3.4.7 the fix will be in that version too. I've already back-ported the fix to the 3.4-dev source code.

dc42 created this issue in Duet3D/RepRapFirmware closed M112 doesnt stop all movement #927

@hpiz both duet3 6HC and duet 3 mini 5+ have a VFD header. 6HC next to the erase header , mini close to the middle of the board.

See the wiring diagrams at https://docs.duet3d.com/en/How_to_guides/Wiring_your_Duet_3

I'm one of those crazy people, instead of buying a few proper cables, I decided to just make a whole new machine. Got Igus continuous flex 16awg for my medium current cables. Been building for a month, gonna take another 1-2 but it should be a nice upgrade.

-3.5kw ATC spindle
-400w Servo Motors (2 on Y for gantry, 1 on X)
-Dual 2510 ballscrew Y drive
-1605 ballscrews on X and Z
-400w Stepper for Z
-2ft x 4ft working area

It's a beast.

@hpiz said in Yet another CNC improvement (Outside machine limits):

I just tried this with some manual gcode entry.
Starting at X-11
G1 X-50 F50
waited a few seconds until it was about a 1/4 done with the move
G4 P0 M5
Spindle stopped immediately.

That's expected. GCodes received over HTTP or from PanelDue are not synchronised. GCodes read from a streaming source are synchronised. So to test the synchronisation, put the M3/M4/M5/G1 commands in a print file or a macro file. Let me know if you find a sequence that doesn't work as expected.

Another option could be to use M0 with an additional parameter to terminate printing without waiting for movement to complete, and to terminate any moves currently in progress.

I see that Marlin uses M410 to stop all steppers immediately. But the documentation doesn't specify any other effects of M410, such as aborting an SD card print, turning spindle motors off etc.

@adarshsimon said in Allow slower minimum movement speed:

@bot "two moves of a print movement" means two axis have to move or two movement commands of a single axis would do?. Thanks in advance.

If you did two consecutive printing commands along the same axis but at different speeds, jerk would be applied between them, even though it could be avoided.
