M571 not recognizing extruder moves

too · 4 Oct 2021, 12:00

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!

Attached the full config file:

@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.

dc42 · 5 Oct 2021, 12:58

@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 · 9 Dec 2021, 15:21

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

dc42 · 9 Dec 2021, 21:40

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

too · 10 Dec 2021, 09:54

@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 · 10 Dec 2021, 13:32

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 · 10 Dec 2021, 19:13

@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 · 13 Dec 2021, 08:26

@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

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.
