    Well i had a bit of trouble. The new 8pin micro i bought for this unit was not supported by any of my programmers. After struggling for a while i decided to order another part that my hardware supports. Hope to receive it soon....meantime i made a few changes to the pcb to be able to connect my programmer to the board. The lengths of the ball screws are almost finalized

    Update....i managed to sort an old pc to control the machine. Loaded and tested Mach3, all good. The little power supply/converter is now programmed with the correct 8 pin micro. Will test it soon

    Success....the little unit is working very well. I am getting a stable speed ref to the VFD. Everything is linear and spot-on, without tuning i managed to get 150.3 Hz when i selected half speed. Time now to complete the last bit of wiring and tidy up the panel.

    The only thing i didn't check is the power consumption on the 5V side....cause my psu can only supply a maximum of 1 Amp.

    Finally completed the sizing of the ball screws, hopefully i did not stuff up the sizing. The ends have been machined and they just shipped them out. I have decided to dump the cheap 5 axis breakout board, ordered a better quality unit. For a start the machine will run off the pc with printer port and Mach3...but i plan to buy a more modern control system, i guess i need to make sure the machine performs well mechanically before i spend real money on the controls

    your electronics skills are million times better than mine, do you have an idea of the final price of that box all hook up? Keep up

    Between home renovating and work the build is slow atm. I did manage to start milling another section of the z-axis. Also made a mounting acrylic bracket for the new bob, hope to receive it soon...

    Just received the new bob, quickly connected and set it up. Happy to report it passed the "worst case" noise test.
    Time now to tidy up all the wiring
