Stepper issues
-
@Phaedrux after changing the esteps like paul suggested the feed rate worked but when I checked config.g the rate was still at 93, I then calibrated using your guide and ended up with a figure of 98! I'm still stumped at what caused it but it's working at least.
I do now have a new issue mind in the form of AutoPID! am I right in thinking once you have carried out the tuning and send M500 it should save the values to the config-override.g? as it doesn't seem to be working every time I restart the printer from off I have to carry out AutoPID or my heatbed faults with slow heating time!
One step forward two steps back!

@jumpedwithbothfeet I think you may be encountering an issue in RRF3 where config-override is not written correctly.
Can you send M115 and report the version string?
Are you using a rpi with your Duet 3?
-
@Phaedrux Yup RPI3B+ with Duetpi gui

Alright, I'm not sure if that particular issue has been resolved yet, but there was just an update released the other day for the Duet3+pi which you should look into updating to as there has been a lot of work done since version 3.0.

@Phaedrux no worries I was holding off updating till I got a basic grasp of how everything works, ill make that my first job now, if it sorts out the override happy days, if not I believe I can manually edit the override.g with the Autotune figures If I read the guide correctly
-
@jumpedwithbothfeet My Bad.
and apologies.
I forgot to tell you that part about changing the config.g and saving it.I'll go back to my corner now!

@PaulHew not your fault bud, I’m the novice here I think I’ve even messed up the firmware upload it’s taking forever to install!
-
@Phaedrux the firmware upload I suspect has locked up, I have “please wait while updates are being installed...” there are no system files on display and it’s been at least 30mins so far is there anything I can do or should I just wait?
-
Seeing as you're using the raspberry pi I believe the means of updating would be to use apt update on the pi. I believe you'd also need to have the unstable repository added.

@Phaedrux does that not only apply to raspbien? I’m running duetpi running sudo update/upgrade was one of the first things I did when I installed the board.
-
I think you'd still need the unstable repository added to get the latest.
-
@Phaedrux i think it did it, i ran M115 again and got this -
