RE: Problems with sensorless homing
Ok so I tested as you reccomended, got best results with X60 and Y90. I ended up bumping The current up for the Y from 1000 to 1200 and tested again and found Y80 to work well. I then had to up the Y threshold to 5 to get it to move and seems to work as expected when it hits the home. However I’m still having issues with the y axis wanting to go the wrong direction sometimes. I bumped the threshold up to 7 and seems to be more reliable. I’ll test this out a bit and let you know if I’m still getting the problem or not.

RE: Problems with sensorless homing
Oh I forgot to mention before switching to duet, on the factory arduino 2560 mega board with tmc2209 drivers I was running the Y axis at 1000ma normal and 50% of that for homing and didn’t have any issues before.

RE: Problems with sensorless homing
Maybe that’s something that should be also changed in the web configuration tool as that is not something I added. I had my concerns about that as I know you don’t generally want it and I had removed it on my other printer still running marlin but left it in as I figured maybe duet had a reason for it. How can I find out the best current setting, I’ve tried between 40% and 90% in increments of 10 already and didn’t have any luck. Here are my motor specs.

RE: Problems with sensorless homing
It’s a completely new setup, I deleted the old files and did a restore to 3.1.1 for my initial setup then used the web configuration tool to generate the setup and then made the changes I needed.

RE: Problems with sensorless homing
@bearer I don’t see why it would be intermittent like it is if that were the case. The homing files were also created by the web configuration tool and I only modified the current %’s. Also it seems worse after sitting over night too. The only information I could find suggested it could be missing a step from a bad cable or driver that would cause it to rotate the wrong direction but I’ve replaced the cable already and both cables I know worked before switching to the duet.

RE: Problems with sensorless homing
@Phaedrux not sure how to post picture on here but here is a link to the post I made on the Facebook group and have posted the pictures there. Yes I had used that guide to set up the sensorless home if, I didn’t try adjusting the steps/s initially. I have now tried between 200 and 400 with 40-60% current. Seemed like it might start moving a little bit better but then it didn’t was to stop once it hit the limits, regardless of what threshold I tried.
