This is our machine as is. Made mostly out of recycled materials. PC and monitor combined in the top box and the stepper motor driver boards and power supplies in the bottom one. The monitor has a touch screen membrane over it for ease of use of Mach3. The head is the latest addition and is of the floating kind letting the machine zero on the material before each pierce cycle. Only recently mounted the control units to the side of the bed and not altogether happy with it. This is why I’m wanting to built a better all in one unit for all the electronics.
