First of all, I’m not an engineer so sorry for the non-technical description.
On to the problem. I just upgraded to XL. Prior to the upgrade my machine cut perfectly straight lines in any direction. Now, not so much. Any cuts directly along the x-axis are wavy. I’ve discovered in the forums that this may be caused by mis-adjusted, worn, defective v-wheels. Hmmmmm, a mystery to me why moving to a new extrusion would suddenly cause the wheels to wear out but, okay, C3D has kindly offered to send me some new ones. Great!
Meanwhile, while I wait for the new wheels I’ve swapped a few v-wheels around to no effect, still have the same problem. Today, while continuing to noodle the issue I looked closely at the new x-axis extrusion and noticed the rail the wheels ride on has a much rounder apex then the old one. The two, original y-axis rails also have nice, sharp apex. My question is…Is this significant, possibly the cause of my problem. Any other upgraders out there notice their extrusion having rounded rail guides?
