New iDraw A3 H SE plotting wonky eliipsoids
Just recently set up this machine, trying to figure out why it seems to start some of them in the wrong location and then veer back on to the correct path.
I have tried reducing speed to 10%, increasing the pen up/down delays to 700ms. Reduced acceleration etc. I think the belts seem bass-string level of tight but I don't have a great point of reference. When I slow it all down, I see the pen move to the same incorrect starting position, pause, then go down, then start moving and tracing along the same path.
I am using the 03 size XWT Micro line Pen from amazon, and some thick mixed media paper.
Does anyone have ideas for what could be the issue?
EDIT: RESOLVED
U/truax suggested I make sure the frame was square. It wasn’t. I loosened the screws to re-adjust it and now it’s plotting nicely!
