y slope with 3.5.0-rc1, not seen with 3.4.6

Adrian52

@balajiramani when I tried the 20x20x20 filled cube with IS disabled there was no debug output (although the y slope is still there).

Here is the output of M122 with IS off.

@Adrian52 I too have the same experience, where IS does not seem to matter.

dc42

@Adrian52 is your config.g file still the same as the one you posted on 23 Oct 2023 here https://forum.duet3d.com/post/325846 ?

Adrian52

@dc42 Probably not exactly - this is my current config.g

@Adrian52 thanks. Using that config.g and starting from your filled cube job file, I have produced a small test case that loses a step on the Z motor and identified the conditions that cause it. I expect to have a fix for it on Friday.

Adrian52

@dc42 thank you very much - looking forward to testing it

dc42

@Adrian52 it turns out that there is more than one cause of this issue. I found and fixed the first one, now I am working on the second.

dc42

@Adrian52 @balajiramani please try the new firmware at https://www.dropbox.com/scl/fo/6afk7iewlw1ycldb8dc4u/h?rlkey=21rm8jcz6aqy3gh523wkmxro7&dl=0. The main board binaries there report version 3.5.0-rc.3+8 and the expansion board binaries are 3.5.0-rc.3+6.

Adrian52

@dc42 the filled cube looks fine - thank you very much.
here is the m122, in case of interest. No hics or step errors

@dc42 I tried it now and it works fine. Thank you for getting dow to the root of the issue fixing it!

balajiramani

BTW, one thing that I noticed with the new firmware is that there seems to be random pauses while printing. Here is a video that shows that. The pause is between 11 and 13 seconds into the video.

Here is the output of M122 taken after one such pause:

@balajiramani maybe open another thread for that issue.

dc42

@balajiramani as @oliof says please create a new thread for that issue.

@dc42 Done. Created https://forum.duet3d.com/topic/35387/random-pauses-with-3-5-0-rc-3-8/1

@dc42 any chance this is not just 3.5.0 and delta related?
We've one printer (Cartesian / IDEX) that's somewhat randomly (but mostly) also producing leaning prints.

For a long time we thought it is ClosedLoop or Hardware related, but running normal steppers etc. now.
Happens both with 3.4.6 and 3.5.1 and always in X-direction.

Kind of sure it's not hardware related by know, but somewhat special setup by now due to all the tests we did.

Let me know if you need any information, or want me to move it to a new thread. Or maybe it's the same error not jet fixed for a different kinematic?

@benecito said in y slope with 3.5.0-rc1, not seen with 3.4.6:

want me to move it to a new thread.

probably would be a good idea to start a new thread. include as much info as you can.
