Hello everyone,
I'm new to the group and was hoping someone has seen this before or would be able to point me in the right direction. I bought a CNC router from ACCTEK in china, and from day one, I've been getting this checker pattern on the surface. I added a aluminum fixture plate to the table and faced it. When i did this pattern came up. I machined some plastic parts and the same pattern appeared on the parts... any idea what could cause this? I have already replaced the x axis ball screw.... i thinking it might be a software issue since its so uniform....
