Hello everyone,

I’ve bought on eBay a CTC I3 Pro B, and I’ve been playing around with it for a little over a week now, so yes I’m a N00b at this. Getting to the point, my printer doesn’t want to print in a circle, its elongated at two sides. I’ve included a picture so you can see what i mean.

After doing a little research into this, I’ve tried tightening the belts with no success, running the printer with different programs Slic3r and Cura with no difference in the print.

I’m not all that confident at programming so I’m not so sure about upgrading or flashing the firmware in case I do some irreversible damage.

Has anyone else has issues like what I’m having and what did you do to combat them?
