Extruder issues with 3.2-beta 3.2 - Duet 3 MB6HC
-
@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. -
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?
-
@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 -
Yup that is correct. 3.2 RC2 has been replaced by 3.2 final, which you appear to be using.

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

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

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

The lights blink like I expect when I run the command. What should give an output?
-
If everything executes cleanly you should get something like
M98 PCONFIG.G HTTP is enabled on port 80 FTP is disabled TELNET is disabled Warning: Heater 1 appears to be over-powered. If left on at full power, its temperature is predicted to reach 893C.Well, actually, looking at your config it looks like you may not have any of the network commands and your heaters may not be overpowered.
-
And for good measure can you post the results of M122 as well when configured as E?
We could also start sending the basic axis setup commands by themselves to see what the firmware thinks is configured and see if it meets expectation.
M201, M203, M566, M584, etc etc
But I think we may get good results from a clean config.

Ok so a generated Config file seems to work.
Hmmm - I will start modifying it slowly to see what broke it. -

With the generated config file it also does not print anything to the console.

That may be normal. In SBC mode there aren't any network commands present to echo back, and your heaters may not be over powered so no warning.
Can you post the generated config?

If you're trying to get percentages with this, just use M913 instead. I set my current to the rated max with M906 and then use M913 to set it to a percentage of that.

I found the culprit:
M906 E900 ; Works
and
M906 E{1000*0.9} ; Gives the issue.Interesting that these seem to work:
M906 X{20000.8}
M906 Y{20000.8}
M906 Z{2000*0.8} -

One more note:

Thanks so much for the help!
The original Config file now works with the one change:
M906 X{20000.8}
M906 Y{20000.8}
M906 Z{20000.8}
; M906 E{10000.9} ; This seems to not work
M906 E900
;M906 U{1000*0.9} -

My homing macros try and set stealthchop and sensorless homing. To do that I have to cut the current to 30% using the M913 command. So if I cut to 80% at first in the config file, do I then cut to 80% * 30%? Then set back to 80% when done?
