I have a cnc router that can control the aspirator and dust hood via custom M codes that I've added to the ladder. Depending on the job, material, and tool involved, I may want either of these to be on/off, or up/down. For the time being, I have stolen the machine active air (aspirator) and turret active air (dust hood) coolant function to represent these function in my custom post processor, which gives me the control that I need. The downside it that it really seems like a kludge and I end up having to explain repeatedly to other folks how to use these functions. Is there a way to rename them or add another set of cooling options that I can appropriately call aspirator and dust hood?
