I was working on a new power distribution box. I did not notice the stepper motor was not plugged in to 12v. The focuser was powered via USB and I then plugged in the 12v DC. (Was not thinking). Now focuser motor just makes a sound when move button pressed. Also focuser seems to reset. Any recommendations where to start checking/troubleshooting? I did verify the 12v DC is working myfocuserpro v1 Arduino Nano NEMA-17 PG27 DRV 8825 LCD Temp probe Best, Steven

FYI. Found the problem and fixed. One of the jumper wires for 5v had a hole in the insulation and it was intermittently causing the TX pin to go high! Put on some electrical tape and everything is running smoothly. Used it last night and it worked flawlessly. Thanks again!

Yes. I messed around a little more last night. I find that if I "verify" the sketch (to make the compile prior to upload a consistent time period) and then hit upload and then in slightly more than 2 seconds plug in the Nano Board, it will program (a fair amount of the time). Thanks for the reply and for the hard work on this project. Best, Steven P.S. Found a potential bug in the Windows app. I changed the "version" in the arduino sketch to add a "1" as I modified the code (motorspeed). When I try...

Short version: I cannot update the Nano with a new firmware from arduino IDE, it just boots into the sketch. Do I need to do something to enable reprogramming of the Nano? Long version: (no reset curcuit built) I was able to successfully build a focus controller using an Arduino Nano. I first uploaded v255 and got it to work (was working on macOS). Once built, moved to Win10 computer. Downloaded new firmware v263 and tried to upload. It would timeout in arduino IDE. I messed around with the reset...
