I’m going to be upgrading things on my 4’X8’ Chinese CNC but I’m finding a more pressing matter is making it so it can run on newer 64bit systems without fancy proprietary connections between the PC and controller board.

I currently have a controller board by KSI Labs, LLC for Mach3, the BOBs for the optical sensors, PCI card for the PC and 25” cable. It wasn’t cheap but wow it works great and Sergey was incredible getting me all set up and even helped me reprogram my VFD to actually work right since the Chinese factory didn’t.

Things I have and still need when I switch:

Spindle Control variable speed from 700 rpm to 24000 forward and reverse
XYZ homing optical sensors.
+&- proximity sensors/switches for the X,Y & Z
Touch plate
Laser cross hair
Water pump
Touch Probe
Remote pendant (uses a USB stick in the PC)

Soon I plan on upgrading from steppers to servos and adding a vacuum table but those are a whole other project.

So what I need is help getting a great board so I can run Mach4. I’ve searched the forums and see older posts on things. I love the way the CENTIPEDE is setup with almost everything I need on one board and only needing the BOBs to connect the homing sensors.

Any suggestions would be appreciated.
