Hi tricky

I am working my way through a TCL project and now have it working although much refinement to do , but It does handle external threading fairly nicely.
I used the original stepper motors and spindle motor but the lenze controller fell over and I had to get a DC drive for the spindle motor. Used this one https://inverterdrive.com/group/DC-T...0-Isolated-1Q/ Dont be tempted to the non isolated version- they can bite

Kept the original 24 V power supply initially. Not sure at this stage if it will be up to the job. but it worked for me . (Good enough to start with)
I was trying to keep it cheap as it was to be just a learning project so got a pair of stepper drivers and a BoB from Ebay (cheap as chips )

Mach 3 will not give you reliable threading I tried it with UC100 controller in USB .
I have been guided to Linux. Mach 4 claim to give threading but it is a mountain to climb and a costly licence particularly if you cant get it working. Linux is free and works on a relatively low grade machine .

If you are throwing out the boxford boards there may be interest on here!
