Remapping extruder motor turns the extruder temp display to 0
-
Hi
I am rebuilding my old machine with Duet Ethernet and everything starts to be ready but:
I can't get the extruder motor moving. Last time I used the printer there was no problem with extruders that I had 2 that time.
I run an ancient firmware (1.21) because the RRF3 would take too long time to get around.
The problem in a nutshell:
I would like to try to remap the extruder into some other channel (driver 4 for example, I got plenty of drivers because of the Duex5, Y and Z are double motor stages so they are mapped partially on the DUex5 and working perfectly) to try to eliminate the possibility of the driver chip being damaged (allthough it seems unlikely).When I try to remap the extruder, my tempreature reading goes bonkers, it shows 0.
Basically if I touch the E-motor mapping, things go weirdly wrong, but I can't get the sucker moving with the default mapping (leaving E out of M584 of the config.g).
I am starting to loose my sanity.
Only M584 Y1:2 Z8:9 with M563 P0 D3 H1 gets me correct temp readings and XYZ movement.
If I change the tool definition M563 P0 D3 H1 to M563 P0 D4 H1or anything else, I get the message "G10/ Attempt to set or report...Non-existent tool: 0".
Cables and motor checked, connector brand new and clean.
(Here's a practical way for that btw: "short" the cables of one phase from the connector with a piece of wire and turn the motor by hand- does it gain mechanical resistance with the shorting? If yes, all good. Then do the other phase.)
Here my config.g:

G90 ; Send absolute coordinates...
M83 ; ...but relative extruder moves

How many extruders do you actually have?
M584 Y1:2 Z8:9 E4
That seems correct if those are the drivers you are using.
M350 X32 Y32 Z32 E16:16:16 I0 ; Configure microstepping without interpolation
M92 X320 Y160 Z3200 E500:500 STEPS PER MMHere you have M350 E with 3 values for extruders. There should only be one. And for M92 you have 2 values, but should only have one.
M566 X1200 Y1000 Z5 E5000:5000:5000 ; Set maximum instantaneous speed changes (mm/min) “JERK”
M203 X22000 Y22000 Z600 E1200:1200:1200 ; Set maximum speeds (mm/min) SPEED
M201 X700 Y700 Z100 E250:250:250 ; Set accelerations (mm/s^2) “ACCELERATION”Again here you have 3 values for E, but you should only have one.
M563 P0 D4 H2 ; Define tool 0
The main problem is your tool definition. D4 means you're trying to use the 5th extruder drive. Which doesn't exist. And heater 2, which also doesn't exist based on your heater definitions.
Try this instead
M563 P0 D0 H1 ; Define tool 0The only thing you need to do to remap the extruder driver to a different driver is to change M584 E#
A useful way to check for syntax errors in config.g is to send M98 P"config.g" in the console. It will show any error messages that may get lost at startup.

It's really not so bad. The online config generator tool is really good at getting you a sane starting point.
Give it a shot for RRF3 and see how the config.g looks

Oh, those extruder steps etc are from the past, totally forgot to remove then when changing into only one extruder.
Will try with proposed fixes this weekend, thanks!
What I am afraid of in the RRF3 is the changes in the logic of setting things up. I had hard time to get my head arount the more clean Gcode approach of older firmwares and still am far from really knowing what I´m doing so the new tricks look like a proper can of worms

@PropellerHat You can update to RRF 2.05.1, and (I think) you won't have to change your config.g. It's also got lots of bug fixes. https://github.com/Duet3D/RepRapFirmware/releases/tag/2.05.1

Hi
After the proposed tweaks everything looks great!
Extruder does its job as supposed to.
Will consider updating the firmware just a tad
Thanks!
