M221 - Request for help for proper extruder drive mapping DWC

I think you should read the entry for M584 on the creation of new axis.

https://duet3d.dozuki.com/Wiki/Gcode#Section_M584_Set_drive_mapping

I'm not sure what your U and W axis are being used for.

I don't think it matters so much in RRF3, but maybe use V instead of W.

Also ensure you're defining all your axis in the subsequent axis commands. You're missing the W axis from M906 for instance, and you're defining E in two separate commands and overriding the Idle current from I65 to I20.

@code7 I second what @Phaedrux said about using V instead of W. It always used to be the case that axis had to be created in the order XYZUVWABCD. It may be different in RRF3 but I'd stick with using V instead of W just in case.

Also, as @Phaedrux said, you need to have motor/driver commands for all axes that are defined in M584. That includes M569 (drives 5 and 10 are missing from your config.g).

Not that it's relevant to your extruder issue but you've only set axes minima for Z and there is no axes maxima.

At the end of your config.g there is a G2 A0 but nowhere else is there any mention of an "A" axis. Suggest you remove that command or replace the "A" with a valid axis letter.

Once you have put all that right, check on DWC STATUS Page that there is only one extruder drive displayed and that it is drive 0. If it isn't, hit the "Change visibility" button and deselect all drives, then select just drive 0.

Thanks for both of your suggestions. I have implemented all of your suggestions but am still having this problem. I would like to be able to map the DWC Extruder to E10 but don't see that this as an option and wonder if this possible? Danal (God bless him) helped me design a custom extruder circuit that runs off of E10.

Phaedrux

Copy and paste your updated config.g into a post here so we can see all your changes.

Here is the updated config.g. I've also removed all references to the U and V axis as they were for testing.

Can you explain a bit more about what you're trying to accomplish? What is driver 10? What did Danal create for you? Was it working before in RRF2? Do you have a config example from then?

@code7 said in M221 - Request for help for proper extruder drive mapping DWC:

M574 U2 S1 P"exp.E2_STOP" ; configure active-low endstop for high end on Z via pin zstop (configured this pin for a Spool Rewind dummy endstop. Can use XYZ endstop as well with +)

You still refer to U axis endstop here.

deckingman

@code7 What @Phaedrux said plus can you explain what hardware you are using?

By that I mean what board and any expansion boards.

I'm making a guess from you signature and the config.g file that you only have a Duet Wifi. In which case you only have 5 drivers (0 to 4). You might have a Duex 5 but it doesn't look likely from the config.g. A Duex 5 would give you 5 additional drivers which would be drivers 5 to 9.

So driver 10 would need to be somehow connected to an expansion board or the expansion header. But although it would driver 10, it can't be extruder 10 because XY and Z take up the first 3 drivers (0 to 2). So what I think you are trying to do is connect extruder 0 (the only extruder) to driver 10 which is an external driver connected to an expansion board or the expansion header.

But this all conjecture and deduction on my part so we need some more information about the hardware. A picture or two might help.

code7

@Phaedrux

Thanks, I removed this line.

This was created in RRF3 to automatically speed up the extrusion feed rate based on an external trigger for closed-loop control. I was hoping to do this within the firmware, but Danal said the FW and Controller would not be able to react quickly enough.

code7

@deckingman

Yes I am using a Duet Wifi with the external controller and motor driver wired through the expansion header. I am no longer using the E0 pins on the board so maybe it would be simpler to not use the expansion header pins for the external controller/motor driver?

Probably. But I have zero experience of using external drivers so personally, I am unable to help. If you can connect the motor directly to the onboard driver, then it becomes a piece of cake.

code7

@Phaedrux @deckingman

Do you know why sending either M221 S150 D0 or M221 S150 D10 has no effect on changing the feedrate?

Phaedrux

Well D10 wouldn't work because there is no 10th motor driver. Not sure why D0 wouldn't work unless it is working, just not being reflected in DWC. What do you get if you just send M221 D0 by itself? Does it report the currently set feedrate?

I have to admit, I'm still pretty lost on what your setup is and what's going on. sorry.

code7

@Phaedrux

Sending M221 D0 returns the current set feedrate: Extrusion factor for extruder 0: 150.0%
But sending G0 E10 F100 still feeds the extruder forward 10mm at a feed of only 100mm/min as verified with an external timer.

Phaedrux

I'm not sure if M221 will modify a G0 command in the way that you're expecting since it's not being detected as a coordinated print extrusion move with an X Y E value. I could be wrong, but if you're sending G0 E10 it will give you G0 E10 regardless of the M221 set.

Try giving it a G1 X Y E command instead and see if it then applies M221. I'm not sure, but that might also need to be executed from a print file.

@dc42 would have to clarify.

code7

@Phaedrux

You are correct and this explains everything. M221 will only modify a G0 or G1 if it contains a coordinated print extrusion move with an X Y E value.

Would it be OK to remove most of the intermediate posts on this topic to save future users from having to read through them?

Sure appreciate your help.
