Hello (again!), A huge relief I got all 3 motors working (wiring and my general panic I guess). I receive this error on calibration. I wonder if it has to do with the torque being too much? William has assured me they have never had this problem. So perhaps I am wrong? I do watch the x-axis at…

I should point out that I loaded sangaboard.ino and then ran some commands like mrx 1600 (which I interpret to mean take 1600/8 steps == 200…all worked)…

If this is the first time with this microscope I would skip the stage calibration and use the webapp to look at the image and to try moving the sample around. Does it move, does it focus, and is the illumination centred. The camera calibration needs no sample and a reasonably well aligned illuminati…

Thank you @WilliamW ! Q: Do you have the STL to the updated small gears that seem to grip better? I’d like to try them…I recall there was a SCAD file just hoping for an STL like the others? Thank you.

This one? Tighter fit small gears - Contributions - OpenFlexure Forum . The compiled STLs from the merge request linked in the third post are not there anymore, I think the built documents are trimmed after a certain time. I think there will be STLs somewhere in the current master on Gitlab, but I on…

Thank you @WilliamW . Yes, that’s it. I now have the 3 axes moving as (I think) expected I cannot seem to focus. It seems WAY off and auto focus gives me the above error. I keep clicking on auto focus (fine) and it does move the x axes a bit before throwing up it’s dialog box. Any advice on fo…

The fast autofocus is usually the best, unless you have a tricky sample. For any of the autofocus methods you need to be reasonably close before you start. Does the z-axis motor move if you make a z-movement of say 400 steps in the z-axis? Which optics have you got? The lens will need to be perhaps…

Thank you very much for your reply @WillamW! [image] WilliamW: Does the z-axis motor move if you make a z-movement of say 400 steps in the z-axis? Yes. Given the movements (as i understand it) are 8 sequences in a step, 2038 steps for a full turn on a 28BYJ-48 motor I was assuming 400 “step…
