Not really much to say about this. Started some work on the CNC machine, here’s the Z axis bed and the start of the X axis.
The CNC machine is going to have a fixed gantry, with the cutting bed moving to provide the Z axis. All axis are going to use stepper motors and screw-threads to provide movement (the bed screw thread is not attached yet.) The cutting bed has 8 bearings running on stock steel square section to provide smooth movement.
So far things are looking good. Need to scavenge some thick MDF from somewhere to build the gantry and y axis, and need another stepper motor for the bed, may pop out this weekend for a spot of dumpster diving >:).
