Hey Everyone!

I'm a n00b to the laser game, but not to CNC machines

Let me say first my laser is a 900x600mm 100 watt Chinese machine. It's yellow/grey in color (does this even matter?) Has a Ruida controller and manual Z axis.

My question is does anyone have experience upgrading from the stock stepper motors to hybrid steppers & drivers. I'm looking to get some more speed out of my machine because of the higher power i need to engrave at a faster speed. I'm maxing out at 600 mm/s. It may seem fast but over a large its really not.

I'm not really sure what NEMA size my stock motors are but the measure 42mm squared with a 5mm shaft.

Also can I use one of the stock steppers and driver to automate the Z axis for auto focus?? I realize I need to add the sensor/limit switch to the laser head. Thanks for any advice or comments!
