Hello, I'm currently working on a new 3D printer based on this OpenBuilds project (Voxel OX - Extendable 3D Printer and CNC Platform) What I'm using: - Ramps 1.4 - Nema 17 stepper - 12v 19amp power supply The problem is that the steppers don't seem to work correctly. When I test them, some only works when moving with 0.1mm steps and stop moving when moving by 10mm. I'have also noticed that the noise coming from the stepper is a bit loud. I don't know what to test or where to go to fix my problem. Could you please give me some advices? -> Extruder doesn't move at all -> Some stepper look like being more precise and constant -> I can provide you video if needed. -> I have already play with the potentiometer on the Polulu Thanks for your answer! Edouard
Hello, Here are 3 videos presenting the 3 axis. I'm sorry for the quality and exposure. It's maximum light in my desk and my smartphone is very ****** (I'll get a new one soon and could provide you then new videos if needed) But the main problem is presenting: the noise and the way parts move.
To me it sounds like your steps are set wrong. Tell any of the axis' to move 10 mm (at a slow rate as not to miss a step) and measure how far it moved. If you need help setting the steps in the marlin firmware I can help you. Also adjust the vref of each axis. Steve
