I am doing my first Smoothie board conversion. I have a 60W GWieke Laser engraver with Z axis. I am NOT new to CNC conversions. Done quite a few from benchtop mills and lathes to large machinining centers.
I have a 5XC
A few questions
I would like to know if it is possible to fire a relay, that would power the exhaust fan and air blower prior to starting the cut, say allow a given number of seconds for both to come up to speed, and then a delay a given number of seconds to turn them off. (to allow finishing exhausing of smoke/fumes.
In the CNC milling machine world we could use M3/M5 with delays or G4Px pauses to start and stop a spindle for example…
In a CNC milling machine, we would use a 4th axis to drive a rotary indexer. I noted that many that use a Laser Engraver, disconnect their Y axis and connect the rotary axis in its place temporarily.
Since I have the 5XC board, is it not possible to use the 4th stepper axis to drive the rotary axis? or is this unconventional in the Laser Engraver world? I will be using Light burn.

Thanks in advance!
