Connecting to my CNC Machine was created by rusty_parts
Hello, I am totally new here. I've been doing lots of research the past few weeks on getting LinuxCNC running on my ShopBot Desktop machine. I saw somebody here do the same thing under the Show Your Stuff page. I have a computer available with a parallel port through a docking station. I was going to use a Pi4 with a Mesa card but apparently there are none in the world. (Of course, just as I start getting into a new hobby!) Anyways, do I need any other hardware other than the parallel port and the board in my machine? It comes with all stepper motors and I/O installed already.

Short answer: by a Mesa 7i96S, those are awailable.
Long answer:
Parallel port on docking station means it is a laptop, those are no good for machine control due to a lot of power saving features causing latency issues.
If it is a desktop, chances are it is through USB, so those do not work for machine control.
And if you are lucky to have a proper parallel port for a desktop, then i still can not help much as i do not know what the machines uses or how are things wired and controlled.
Could have posted some pictures and awoid reading all of the above! :)
Jokes aside, do post some pictures of the control box and pc with docking station.
BTW, welcome, make yourself at home. :)

I absolutely will post some pictures later! I work for ShopBot as a technical support man and am busy working right now. So once I have some free time I will be back.

Here's a couple pictures of my machines. I have a ShopBot Desktop 24x18" and a Handibot. The Desktop is new to me and came with no VFD or spindle so I am in the process of re-wiring it. I modified the Handibot to accept a 1hp spindle instead of the router that came with it. Both are running on the ShopBot software currently and I want to convert one or both to use with Linux.
