I'm having problems with CNC machine not cutting as it should. I'm using CamBam and a licensed Mach 3 with a cheap China CNC machine. Not sure whether its CamBam or the electronics in the CNC machine, but I suspect its the latter. Was contemplating on replacing the drivers (TB 6600) and the interface Breakout Board. Any advise or help would be very much appreciated as I am new in this hobby. Attached are some pictures that may help.

Where did you get the licence from, did it come with the machine?

Mach 3 came with the machine. I did not use it and bought a legal software with a license as mentioned in my earlier post, which is installed on the computer. So its not an issue with Mach3. Hence I think its got to do with the electronics that came with the machine...dodge stuff I suppose. Any help would be appreciated. Thanks
