General Mach Discussion / Need help getting my stepper motors to run smoothly
« on: January 30, 2020, 05:58:33 PM »
I have built a cnc router and i am at the point where i am trying to get Mach3 to make the stepper motors run. I am using windows xp. I first got the motors to move but very jerky. This is in all of the motors. X,Y & Z. No matter how i set them in the motor tuning nothing changes. Run the driver test and it was very erratic. So i went through the optimization.txt file and did most of the steps. The only one i didn't do was set computer to standard PC vs ACPI PC. Everything else i did. I even had the hard drive reformatted when i reinstalled Xp. After all the optimization i rebooted the computer then went right into mach3 mill. Pushed the arrow buttons and had nice smooth movement. Boy was i excited to think i had it figured out. Well after about 20 to 30 seconds it went back to jerky motion. This repeats every time i reboot the computer. If i reboot and let it sit a minute then open Mach3 the movement will be jerky. I think i must be something in the computer but I've run out of ideas and cant seem to find anything online to help me out more than what i have already done. Any help would be appreciated. I'm using Sain Smart TB6560 motor driver, parallel port breakout board,with nema 23 270 Oz stepper motors.
