The small Z table from LightObject also uses a moderately sized Nema 17, it should also be OK with the built in drivers.If you have our Cohesion3D Rotary or the one from LightObject, it should work directly off the board with the built in drivers, just plug it into the A motor port on LaserBoard and set your steps per mm and max speed values in the config file (get these from the rotary manufacturer).
If this is a larger machine than a K40, just know that you will have to change some settings like the driver currents in the board’s config file.
You should be OK with the built in drivers. If you have an M2Nano style board, it has built in drivers for X and Y.Here are some quick tips to know whether you need external drivers: You should look at the motor rated currents, but as a rule of thumb, I say that Nema 17 Steppers up to 48mm long are OK, as long as you are not putting way too much load on them. They can work up to a point, then you will need external drivers. These are Trinamic stepper drivers rated up to 1.2 amps (RMS value, which is different than the peak which is how most motors are rated). 4A External Stepper Driver and External Stepper Driver Cable : LaserBoard has built in stepper drivers for X, Y, Z, and A.
