General Mach Discussion / CNC Router "Stutters/Loses Position" on Faster Feed Rates
« on: November 28, 2017, 11:07:41 AM »
I am new to this forum, so I apologize if this is posted in the wrong section or redundant.
Earlier this year I put together my first CNC router. https://www.smw3d.com/r7-cnc-diy-kit/ I used a Mach3 usb board https://buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach3-USB-Board with the other components from the kit.
Everything was working great until I started a cutting project that lasted about 1 hour. Running at 30 IPM, it will lose either X or Y positioning and try picking it up again from 1/8" off to 4" off. I also notice that when I bump up the jog rate to 150% for positioning the router, it will stutter or pulsate. Slower feed rates do help eliminate this.
I believe I set up my motors correctly in Mach 3, but has anyone else ran into these issues, or have suggestions on what it could be? It's really frustrating being almost done with a project and then have it ruined because it loses position.
Thanks!
