  • Your project is great. Is it possible to add backlash to the program? I use nema17 with a gearbox, there is a backlash

    Yes, Backlash support will be in Firmware release 125
  • Thanks for sharing your great project!!
  • I have built this project and the rotator works a treat. I used the circuit diagram and code as written however made my own board. I was able to print a 3D ring gear and case to fit the shape of the telescope. It is a great project and I am looking now at the dew controller. So far I have made a number of Roberts projects and all work 100% MyFocuser MyRotator MyUsbController
  • Hello Mr. Brown, can you write this myRotator in Indilibs? I use stellarmate with Indilibs and can't use the ASCOM driver! Thank you, Andy
