Well...

This is my workbench



The machine



The plate



Electronics



Power Supply with Controller and Stepper driver



The cheap CNC board Controller



Do not take care of ugly look. This is just a experimental prototype.

My target is make PCB board for little production, but the cheap CNC Controller have some problem...

With Mach3 at high speeds (but not so much ...) the controller go to a irreversible loop, moving the axis back and forth in a little loop.

Due of this I had to throw away a lot of PCBs. So I decided to upgrade the board with a KFLOP board.

In this thread i walk through the project, step by step.

First step:

Some experiment with KFLOP.

The custom board is for buffering Output, STEP, DIR and ENABLE command, and serial connection RS232 for remote KFLOP control

Second step:

Make a PowerSupply KFLOP dedicated board.

The project on CAD:






Gerber to G-CODE conversion





Some step at Simulator to be sure...



The final result after engraving:
