Extruder issues with 3.2-beta 3.2 - Duet 3 MB6HC

deckingman

@MikeGeppert Did you use the same steps per mm when you configured it as a U axis as you did when it was configured as an extruder? Also, which firmware version ?

Veti

3.2-beta 3.2 -

please update to rc-2

Phaedrux

3.2 final is now available as well. https://github.com/Duet3D/RepRapFirmware/releases/tag/3.2

MikeGeppert

@deckingman Yes same everything, literetly just replaced the "E" with "U".
I did have to use the "G1 U10" as opposed to using the extruder command buttons on the WEB interface.

MikeGeppert

@Veti gosh I couldn't tell you. I guess I can look. It came with the kit I bought. It is a 24V pancake stepper. 4 wire. Like I said it runs great if I change all the "E" commands to "U" so I ruled out any port, wiring, stepper motor issues.

MikeGeppert

@Phaedrux The config file is pretty big and has lots of comments in it. I copied and pasted alot of the G-Code documentation to remind me what they do and what the parameters are. I can post tonight.

For the Extruder I was just using the Buttons on the Web interface.
For the "U" setup I used the console and "G1 U10". I did try "G1 E10" also when setup for the extruder and still got the issue.

Now that I know the wiring is good and the stepper motor work like a champ I am really confused.

MikeGeppert

@Phaedrux OOO Cool - I will thanks...
Is that what @Veti is trying to say with "rc-2" comment?

Phaedrux

Veti was talking about release candidate 2 for 3.2, which is now defunct now that the final release of 3.2 is available.

dc42

To be clear: if you use the buttons in the web interface to command extrusion, the extruder just vibrates?

Please note, most of the extrusion speeds in the web interface are far too fast to extrude through a nozzle. They are intended for filament loading/unloading.

Please post your config.g file.

MikeGeppert

@Veti The stepper motor is a Stepperonline 17HS08-1004S

I am shooting for about 900mA.

@Phaedrux Here ya go (This is the version that has the "U" defined, the "E" is commented out):

@Phaedrux Hmmm the update did not go well. Trying to recover the system now.

MikeGeppert

@dc42 Thanks for the response.

If I do a "G1 E10" I get the same effect.
I actually removed the stepper from the extruder and it is just sitting on the bed now. I am looking at the gear on the motor.
If I set it up as a "U" it turns as expected with "G1 U10".
If I set up as a "E" it vibrates with almost no torque. I can put my finger on the gear and feel almost no torque at all.

Phaedrux

Can you send M98 P"config.g" and post the response?

Your spacing is very odd and I wonder if there is a non-standard character in there causing something to barf.

Could you maybe try a basic config generated by the online config tool just to rule out the config?

https://configtool.reprapfirmware.org/Start

MikeGeppert

@Phaedrux Is this right? I was expecting an rc2 somewhere:
1/5/2021, 10:42:56 PM M115
FIRMWARE_NAME: RepRapFirmware for Duet 3 MB6HC FIRMWARE_VERSION: 3.2 ELECTRONICS: Duet 3 MB6HC v1.01 or later FIRMWARE_DATE: 2021-01-05

Phaedrux

Yup that is correct. 3.2 RC2 has been replaced by 3.2 final, which you appear to be using.

MikeGeppert

@Phaedrux said in Extruder issues with 3.2-beta 3.2 - Duet 3 MB6HC:

M98 P"config.g"

1/5/2021, 10:44:40 PM M98 P"config.g"

Kind of unexciting? Its got a green background I think that is a good thing?

MikeGeppert

@Phaedrux Great Thanks!
Same issue. "U" works, "E" not so much...

Phaedrux

Hmm.. no, there should be a few messages if everything is good and some errors if it's not. I think something is amiss with your config.

Can you try a basic config generated by the config tool?

MikeGeppert

@Phaedrux Sure - give me like 30 min or so.
