We’ve built both the rotators, and created the rotator controller board. (https://photos.app.goo.gl/9WuyWBMQMkqVhmFQ9 – https://photos.app.goo.gl/gKrqERhN8ehH1bFS8) We’ve tested it with steppers using EasyComm commands through Minicom and they function, and the rotators function with a drill on shaft. However when putting the two together (the rotator with the electrical stuff) we are having issues.
The construction is very constrained and I think it’s putting a lot of strain on the stepper motor. The motor drivers get VERY hot, and while it may rotate things a few times, eventually, it stop working. You can hear the sounds the stepper is making as it tries to move but it’s not moving things. Removing the stepper from the construction entirely and testing it on its own shows that it won’t rotate even with no load on it. I haven’t tested them again long after to see if it was just the drivers overheating, or if the steppers themselves are broken (I’m guessing it’s probably the former though).
Any tips on getting the final steps done?
