Speed
Quote from riley1234198 on January 20, 2020, 7:41 pmIs there anything in the config to tweak to get the engraving speeds faster? The board has been working awesome but when i try to run over 6000MM/M the steppers sputter and jerk. I read on other forums that they run 150mm/s and 200mm/s at 6000mm/m=100mm/s is all i can push it.

I believe I went up to 13000mm/m in my setting before the steppers started skipping when I was set at 1/16 microsteps. But different machines will behave different, Stepper motors could be slightly different models as there's a gazilion different K40's on the market. Assuming you have a K40?
A few things to check would be tension on belts, how clean / lubricated the linear rails are & how smooth the axis's move, verify the correct voltages on the stepper drivers (I think .365V is where I set mine) See what you have $110, $111 max rate set at and check what your $120 & $121 acceleration settings are. I ended up going to 1/8th micro stepping and believe I was able to go up to $110=25000 $111-15000 and I decreased the acceleration I believe from 8000 to 3000 as mine seems to run smoother there. Hope this gives you a few places to look.
