I currently have a CNC for wood working from China, its the largest working surface table they could send that could fit in a container. Everything is working fine, but I noticed when the X & Y axis's work together to create circles or a radius, it seems to be slightly erratic and not smooth at all. The holes and radius's all seem just fine and accurate, just a little concerned that something is not quite in tune with each other. My smaller Jcut CNC (4' x 8" working surface) seems way more steady and smooth. Almost like the 2 stepper motors that are on each side of the table for the bridge drive are the ones not in sinc with each other. Is there a fix to smooth out this behavior?
