@Phaedrux Thanks I will have to try that. It would mean the slider on my web interface wouldn't work but that doesn't matter as long as the print gcode is handling it. I saw a YouTube video on the compressor by AvE and I thought it was perfect for what I needed, only I didn't think of how to control it. 😅https://youtu.be/eEF-owkyI-o First part came off the printer today, functional but I have a lot of tuning to do. now I can add post possessing gcode on the to do list as well.
