[3.6.0-beta.3+1] Extruder stall detection

[Leonard03]

@dc42 that is exactly my setup

M584 X0														; set drive mapping for X axis
M584 Y1														; set drive mapping for Y axis
M584 Z2:4													; set drive mapping for Z axis (dual independent)
if global.MMUmode = true
	M584 E3:3:3:3:3											; set drive mapping for virtual extruders
	M584 U5													; set drive mapping for U axis (MMU selector)
	M584 V6													; set drive mapping for V axis (MMU pulley)
	M584 W7 R1 S1											; set drive mapping for W axis (MMU idler)
else
	M584 E3													; set drive mapping for extruder

and

; Tools
if global.MMUmode = false
	M563 P0 D0 H1 F0										; define tool 0
	G10 P0 X0 Y0 Z0											; set tool 0 axis offsets
	M568 P0 R0 S0 A0										; set initial tool 0 active and standby temperatures to 0C

elif global.MMUmode = true
	M563 P0 D0 H1 F0										; define tool 0
	G10 P0 X0 Y0 Z0											; set tool 0 axis offsets
	M568 P0 R0 S0 A0										; set initial tool 0 active and standby temperatures to 0C

	M563 P1 D1 H1 F0										; define tool 1
	G10 P1 X0 Y0 Z0											; set tool 1 axis offsets
	M568 P1 R0 S0 A0										; set initial tool 1 active and standby temperatures to 0C

	M563 P2 D2 H1 F0										; define tool 2
	G10 P2 X0 Y0 Z0											; set tool 2 axis offsets
	M568 P2 R0 S0 A0										; set initial tool 2 active and standby temperatures to 0C

	M563 P3 D3 H1 F0										; define tool 3
	G10 P3 X0 Y0 Z0											; set tool 3 axis offsets
	M568 P3 R0 S0 A0										; set initial tool 3 active and standby temperatures to 0C

	M563 P4 D4 H1 F0										; define tool 4
	G10 P4 X0 Y0 Z0											; set tool 4 axis offsets
	M568 P4 R0 S0 A0										; set initial tool 4 active and standby temperatures to 0C

Those are from my config. But for some reason, sharing the extruder between tools messes something up

@Leonard03 it looks like you have set up every tool has its own extruder. Is that really the case, or do they all use a common extruder? Or do you have a single common extruder close to the hot end, and an individual extruder for each filament spool to feed filament into the MMU?

[Leonard03]

@dc42 The MMU is basically a multiplexer. It has no extruders assigned to it. Just moving 3 axis (UVW) to send filament from the selected slot (defined as a tool) to the extruder. It feeds filaments from 0-4 to the same direct dirve extruder.
After that tool change, it disengage the filament and the extruder goes to print with the loaded filament.
I can get away defining only one extruder with the M584. In this case, everything works as expected, but the downside is that i can assign only one filament config to all MMU slots.

@dc42 said in [3.6.0-beta.3+1] Extruder stall detection:

it looks like you have set up every tool has its own extruder.

I think so. Every tool has its own extruder, but all extruders are using the same driver (3) and the same physical extruder
