Hi, I am using a QIDI Tech Dual. Recently, I started noticing this weird issue that has stopped me from being able to print anything. I slice in Simplify3D and upload the gcode to Octoprint. The first thing my printer is supposed to do is move the build plate to the top and the head to the start position. For no reason, the head has started moving painfully slowly, to the point where I have to cancel the job because I don't want to wait for it. I have tried different models and even upgraded to the latest build of Simplfy3D. This happened in the last version as well. I have tried jogging the build plate and the head in X, Y, and there are no issues with speeds at all. The belt isn't broken as far as I can tell and the steppers work fine in jog position.


Can anyone see any issues? I have not touched my configuration for years and it's always worked. Thank you.
