Hello

I have built a Hobby CNC router and I am using Keling 382 oz-in steppers for the 3 axis. The lead screws are 1/2 inch 10 tpi ACME. The power supply is a 24 v 16.7 amp and the driver board that I am using is a TB6560. I am using Mach3 for the software driver.

Jogging the motors in all axis they run very smoothly with no problems but every now and then I get a stall out while running. (you know the sound the wild harmonic buzz and the motor stops for a split second) I'm new to the hobby cnc scene and also new to the motor tuning scenario in Mach3. Below is the way that I currently have the steppers setup in Mach3 and any and all advice would be greatly appreciated as I am very new to the tweaking of this program.

Steps per inch set at 4000

Velocity set at 50

Acceleration is set at 25

Stop pulse is 4

Dir pulse is 4

TB6560 board is set to full amperage and 1/2 step on the dip switch settings

Thanks For your Help
