ABB IRB140

Hey everyone

Next year, I will be building a CNC myself as a school project.
The idea is to use an old ABB IRB140 and mount a spindle on it.
I dont know anything about CNCs nor have I worked with one.

My question is, where to begin???

I welcome all information or help.

Thx in advance!!

First see if you can work out or find documented the Denavit-Hartenberg parameters for the robot.
Also look at the sample robot configs which include a visualisation of the robot, For example:
linuxcnc/configs/sim/axis/vismach/puma/ in the config picker.
