I have two x carves and have been very happy with both. I did also buy a gryphon cnc 4 x 8 kit to be able to make some larger projects. After a few months of beating it hard I need to replace the bearings, the stepper pinion gears, and the z axis gear racks. Anyone had to do this before? I can’t seem to find anywhere to buy the makerslide parts, like the v groove wheels, except for inventables. I am going to try and see if they are the same, but it would be great if anyone has some insight.
