I added the plumbing for a 30 l/min air system with a flow control and an adjustable power switch. I routed all the plumbing into the harness loom. I always try to get it as clean as I can. The compressor is a kit that brovr makes and came with everything except the adapter I made with my fdm printer. I am going to get some clear resin in for my SLA and reprint it. I am just waiting for the SSR to be here for automatic operation. With some help on here I got the eprom to hold the GRBL programming for the limit switches and allow the automatic use of the air system.
