I've recently bought a CNC Mill and it doesn't work

General CNC CNC Routers

Hey,

I’ve bought a 4 axis CNC mill for a little bit of wood working, but I tried using Mach3 (which was recomended for the CNC and it was on the included CD& USB-Stick) but it won’t budge, then I tried GRBL Control and again no movement, nothing.

Possible plan B would be to just buy another controllboard (GRBL or one that works with Estlcam), but if this works just fine and I did something wrong I would prefer the “plan A”.

Do you have any posible solutions?

Here’s the site I bought it from and some pictures of the controll circuit down below:

Can you describe what you have done to try to make it work in detail? It’s hard to guess what might have gone wrong otherwise!

In addition to what @mcdanlj requested:

  1. Picture of the control panel while powered up.
  2. Manufacture/model for controller
  3. Links to schematics/ wiring diagrams
  4. Links to user manual for machine/ controller

Some simple checks?

  • Does the PC have the driver installed and does it connect to the controller
  • Is there any movement at all under any user input conditions?
  • Is the Estop button “disengaged”?
  • Are there any manual functions available that you can use to test movement without the PC software?

Ok, somehow it worked now.

It looks like I have just used the wrong input controlls every time. :sweat_smile:

And after finally finding and using the correct manual it was much easier.

Are you good now?

Yes, everything works fine now and thanks for your help.

If you get sick of Mach. That CNC machine is very much like the machine I have and mine has a DB25 connector on the back of the control box. I wired an Arduino Nano to a DB-25 adapter(wire screw connectors) but there are direct to Arduino shields( https://www.cnc4pc.com/db25-motion-controller-arduino-shield.html ). You can see the control labels and pin numbers on that page.

I’ve use bCNC, F-Engrave, CNCjs to control it since it’s just GRBL and most all software can communicate with GCode. I’ve used Kiri:moto to generate tool paths. http://grid.space
