Which is the better control, and if its the > rs485, what module does that need RS485 is likely to give more info about what is going on inside the VFD, but will have worse real-time performance. So not as good for CSS on a lathe but probably OK on a mill. (Except it might introduce some dither on where the reverse is when rigid tapping) But RS485 is only an option if there is an existing LinuxCNC driver, or you want to write one. I am using this to hook up my high-speed spindle: https://www.amazon.co.uk/DSD-TECH-SH-U13-Alligator-Compatible-black/dp/B082KKG55T With the alligator clips cut off. No, before you say it, they probably won't deliver to you, but you can probably find the same thing from a US vendor. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1912 _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
