Hello,
This is my goal.
I want to add a laser to my CNC machine so I can do hybrid projects with vectric aspires new hybrid laser module.(https://www.vectric.com/products/laser-module)
I’m wondering what I need to upgrade to be able to do this.

Currently my diy CNC is using Mach 3 on a the cheap popular mach3 5 axis break out board.

My machine consists of 4 Axis. 1 Dual Gantry and lathe. Spindle (PWM), This currently uses all my pins. 5 stepper motors = 5 axis worth of pins then the pwm for the spindle.

Eventually I may want to upgrade to Servo Motors and ATC and Auto Zero (Touch Plate).

It seems like mach3/4 can not accommodate me for this yet and I may have to learn some gurble madness. Any help in the right direction would be greatly appreciated. What controller/new set up I should need.
