You need to change the steps per inch number in Mach under config -> motor tuning to mach your laser.
I believe you can set up two profiles, one for each machine but I have not done it so you will need to look it up in the manual.
The other problem is that the current required by your Nema 17 may be far less than your Nema 23. If it is you are going to burn out your steppers unless you changed the current setting of your controller.
