onstep: Howard Dutton's smart hand controller github OnStep is a computerized telescope goto controller, based on Teensy or Arduino control of stepper motors. It supports Equatorial Mounts (GEM, Fork, etc.) as well as Alt-Az mounts (including Dobsonians, and the like.) OnStep was designed, from the beginning, as a more or less general purpose system and provisions were made in the firmware to allow for use on a variety of mounts. stellarjourney , Unified driver thingiverse groups.io trinamic's stallguard and coolstep hoshimiya's coolstep : Gary olsen Fysetc E4 ( esp32 wroom + tmc2009 + wifi + bt) Group Cloudynights Graydigitalarts faq https://learn.watterott.com/silentstepstick/faq/ Config generator: baheyedin
