Thinking box. Building a CO2 laser

[Robin Hewitt]

The 6040 uses 200 step NEMA17 motors which are really zippy at 12V.
There are no cutting forces, you really want to keep this as light as possible, especially if you want to scan a cross hatch engraving.

I see. What about the step angle?
I see there are 0.9, 1.2 and 1.8 angle.
Should I go for an nema 17 also for the x axis ?

Sorry cross purposes, I am trying to do too much and, apparently, failing miserably

I am talking about the cheap Chinese laser, you are talking about converting a cheap Chinese router table in to a laser

Please ignore everything I said

hehe
I have ordered the rail kit from mjunit Link here want to build co2 laser cutter/engraver from scratch :) I think that is better than ordering theese systems.
Regarding the motors and drivers, I am a bit confused... There are a sh*tload of different nema 17 and nema 23 motors.
They recommend nema23 motors since they have 8mm shaft. And the kit contains 8mm couplings and mounts for nema 23. But I am lost here...so many motors to choose from.

What do I need to look after regarding motors and drivers?

I would be gratefull for any tips regarding motor + driver :D

Just received the parcels today. Well packed.


Here is layout


Will build a frame of aluminum extrusions 2020 and 2040.

More later..

PS.
Any tips regarding motors + drivers? ;) It has 57mm mounts.

Wrong motors...
