Thanks. Actually the machine has a EthernetSmoother that has a breakout board and a 0-10v signal that says it has a dedicated on board 0-10v signal that can be used to control a spindle.
Being new to CNC or 3D printer machines myself, we have another person who uses a software package to create a 3D image of something we need to make on Hass CNC machines. After the 3d image is created he downloads that into the Hass machine.
With what we are looking at trying to do now, he will still be creating the 3D image but at the moment he plans to use a program called Slic3r to create the G code and then download into the EtherSmooth Stepper. My question is since he planes to use Slic3r which appears to be geared more toward 3d printers how will it, or how does it know when the program finishes slicing the 3d image to create the G code to control the on/off and speed of a spindle?
