I just might do that, there's a little bit of worry in me about the spindle not being able to be turned off through the master-switch in case something goes wrong. For right now though I've made a little setup where the VFD is right next to the operator.

The CNC has three axis, the spindle is controlled by an external Chinese VFD though I'd like to see if it's possible to control the spindle through Mach4. There are no limit-switches or home-switches on the machine, I have switches available to be used but they aren't installed.(If you're careful with your gcode, do you even need them?)

It seems on the parallel port board, the PUL+5V and DIR+5V are attached to terminals P2-P7, then everything else is tied up into a wire nut with two wires going to GND. It seems like that's all removed because I just take the PUL- and DIR- and put the two wires into the one "com" port.

Hello!

I'm pretty much a "noob" in this CNC world and was hoping I could find some help here. I've recently came into the possession of a built DIY CNC and it's using this board: https://www.steppermotorcanada.ca/db25-1205f.pdf

Though I'm wanting to update to Mach4 to be able to use a computer I plan to 3D model on using Fusion 360 which is Windows 10. The CNC came with an uninstalled SmartBOB-IsoUSB PMDX-424 board. The drivers used are: https://www.makerlab-electronics.com/product/stepper-motor-driver-dq860ma/

Is this possible? I wasn't able to find a wiring diagram, maybe it's supposed to be straight forward.. hah.
