Hello, I recently completed my build of the SMW3D 1500x1500 ox. I am fairly new to CNC, but not a beginner as I've had my C-beam running well for a few months. I bought the stock package that included the Gradus M1 board with Bigfoot drivers. After the mechanical build, I've had issues with accuracy (pocketing holes) that I'm in the process of trying to figure out. Now my ox doesn't seem to have the power to engrave/trace anything. I'm using a V-bit (1/8" diameter) that I'm engraving at .5 mm deep. When I cut air, the machine does what it is supposed to, but when it attempts to cut the wood, nothing moves. It seems my drivers are under powered now - before they would at least cut into the wood, but now they can't hold power to engrave at less than 1 mm. Below are some pics of what I'm attempting to cut, and what actually happens. I've also included a pic of how the holes are coming out (I am attempting at putting into the spoilerboard)..... This is where I was originally, so if anyone can help with this too, I would appreciate it.
