Im running the MPCNC with ESTLCAM saving the cnc program directly in ESTL CAM(new support for arduino is great !) onto an sd card and then inserting the card into the lcd controller unit I bought with the kit, has the firmware that came already flashed.
My question is what dictates the speed the z axis moves. I need the z axis to plunge quickly, I gradually increased the plung feedrate in ESTL but when I got to 8mm/s it seemed to stop actually going any quicker than this. Is there something in the firmware limiting Z to 8mm/s ? Is it unwise to try to make it go any faster than this ? I’m drilling very small holes (0.6mm) through stacked soft plastic straight up and down so there’s not much resistance at 30,000rpm.
Any info/advise appreciated, I’m quite new to milling.
