Bug: RRF 3.3beta2 - G92 B0 changes E axis position

Phaedrux

Yes sorry for the delay. You've given us a lot to chew through.

DocTrucker

@Phaedrux cheers, happy that they've been picked up on and me trying out some less common processes may have brought some fruit for the beta testing. With any luck the issues will be a different perspective on exisiting issues that helps with other current challenges.

Edit: Are you a part of the official Duet team now too or helping out keep things in track on the website?

@DocTrucker, when this code executed from the trigger, was anything else happening? I am wondering whether the change in E value may have been caused by a command executed on another channel.

DocTrucker

@dc42 in this example I was running through the code line by line in the command terminal on DWC while the machine was idle.

@DocTrucker, thanks. Please can you try the firmware build at https://www.dropbox.com/sh/6203euyyobllic5/AABTHIbn7F_maK9p-oy7vq3Ea?dl=0, which includes a fix for the other G92 issue.

DocTrucker

@dc42 Thanks, I will try to have a go on it over the weekend, Monday at latest.

Error: M997: In-application programming binary "0:/firmware/Duet2_SDiap32_WiFiEth.bin" not found

I don't normally have a firmware folder?

I re-ran the tests today and this is the shortest way of replicating the issue:

Can we have another 't' in attempting please?

3.3 adds the use of a /firmware folder to help clean up the sys folder.

Are you also using DWC 3.3 beta2?

You may need to create the folder manually and move your firmware files over.

@phaedrux said in Bug: RRF 3.3beta2 - G92 B0 changes E axis position:

It's sufficient just to upload the IAP file through DWC again.

DocTrucker

I'll have a go first thing tomorrow. Things overran today.

@dc42 Problem remains...

@doctrucker, thanks, I've reproduced that. Looking into it now.

dc42

Fixed in next 3.3beta.

@dc42 great!
