M571 not recognizing extruder moves

too

Hello,

I am trying to set up M571 "output on extrude" on my current machine, however I am a bit stuck.

The output of the pin never changes, whether I am extruding manually or from gcode.
I have tried several ways and different pins all without success

M571 S1 P"0.out8"
M571 S1 P"out8"
M571 S1.0 P"0.out8"
M571 S1 P"0.out7"
M571 P"out7" S1
(you get the idea)

I can successfully invert the output pin with the ! modifier and measure my VIN voltage, but the pin is not changing when the extruder is active.

The extruder is driven by a 1XD board with CAN address 23:

M569	P20.0	S1		; X forward on 20
M569	P21.0	S1		; Y forward on 21
M569	P22.0	S0		; Z forward on 22
M569	P23.0	S0		; E forward on 23
M569	P24.0	S0		; U forward on 24

I have figured out that I cannot use the 1XD as output, I get the following error when I try:

M571 P"23.out1" S1
Error: M571: Remote ports are not supported by this command

I suspect that I haven't configures the tool correctly, but I cannot figure out what to change:

M563	P0	D0		; Define tool 0

If I enter the drive number differently I get an error:

M563 P0 D23.0
Error: M563: bad drive number

Does Anyone have an Idea?
Thanks!

@too

Have you tried executing config.g using M98 P"config.g" from the DWC Console to see if any errors are reported?

Errors in the file during boot are usually not seen.

@too I've looked into this. Currently the M571 feature does not work when the extruder drive is driven from a CAN-connected expansion board. I will work on a fix.

too

Hey @dc42, just wondering if you have managed to fix this?
I couldn't see anything about that in the changelogs..

dc42

@too I'm sorry, this has not been fixed yet but it is on the list.

too

@dc42 alright, that's good to hear... Any idea when this will be fixed time-wise?

Any idea for a workaround in the meantime?
Could I add a second driver to the extruder axis that is mapped to a driver on the 6HC to make this run? I'll go ahead and give this a try..

too

I was hoping to get this working by adding a second driver from the 6HC to the E axis without luck. I am now not sure if this is because of some limitation of RRF that I didn't see or if I am implementing this wrong:

Is there any workaround or quickfix that you can come up with to control a pin according to extrusion moves? Could I somehow use a driver_Enable signal configured in a certain way?

Phaedrux

@too said in M571 not recognizing extruder moves:

M584 E23.0:0.0

You've defined 2 extruders, but I only see settings values for one extruder.

Do you have a tool configured to use that extruder?

too

@phaedrux Yeah, so far I have only been using / configuring single-tool machines. The Extruder tool on 23.0 works fine. but because its on a CAN-extension board the M571 command doesn't work.

The tool is defined to use both drives: M563 P0 D0:1
I have tried to configure the Extruder tool with drives 0.0 and 23.0 and had partial success: If I write M584 E:0.0:23.0 then the output on extrude pin switches, but I don't see any STP/DIR signals on 23.0.
If I write M584 E:23.0:0.0 however, I get no output on extrude pin switches, but I see STP/DIR signals on 23.0...

Reading through the gcode wiki again I noticed that I probably need to define a mixing ratio, as our slicer doesn't output multiple E values...
I have added the corresponding command to the config.g:

; set tool mixing ratio
M567 P0 E1:1

........ and now it finally works!
I have added this block onto the end of the config.g

; SETUP OUTPUT ON EXTRUDE
; additional "virtual" E driver
M569	P0.0	S0
; updated driver mapping
M584	E0.0:23.0		R0

Thanks for sending me into the right direction @Phaedrux !

@too I'm sorry this has taken so long to resolve and I am glad you found a workaround. I am implementing a fix for M571 when the extruder is driven from a CAN-connected board in RRF 3.5beta2.
