General Mach Discussion / Re: Motors do not turn continuously

Thanks for the fast response Fastest 1 and Hood! I don't have any prior experience in Mach3 and this is my first CNC router kit project .. Nor have I very familiar with stepper motors and sorry for the confusions ..

  Continuous jogging mode should be just that, continuous.

   What is your motor tuning set to?
for all 3 axes, I used:
Steps per: 1280, Velocity (mm/min): 400, acceleration (mm/sec^2): 125, G's is 0.3237738, step pulse 1-5us: 0, dir pulse 0-5: 0

   Is it a 1.8 degree stepper or .9? Could it be the stepper stalling?
It is a 1.8 degree stepper. I'm not sure what is a stepper stalling?

   Have you ever had this combo working before? Do you have any prior experience with Mach3 and or motion control?
No. I don't have any prior experience ..

   What voltage are you running the TP6560 on? (is it a TB or TP?)
TB6560 (http://www.shapeoko.com/wiki/index.php/File:HY-TB4DV-M_Ebay_CNC_Controller_4-axis.pdf)
Sorry for the typo!

   Are you saying the stepper makes 1 revolution or 1 step if you hit the key once? If it is a step, how are you measuring it?
Now after I looked up wiki .. no I didn't meant a step ..
In step mode, if I start with X at 0, and I hit the arrow key once, the motor continuously turns until X reaches 1. So I meant ,it completes 1 unit of movement, not 1 step. Since I set the units to be mm, I guess it should have turned 1 mm distance?

   Do you any micro stepping value set or is it adjustable?
I don't quite understand this question .. where is this setting?

If motor tuning is not set correctly, how should I modify them? Are there any equations to follow or should I just guess and try?

General Mach Discussion / Motors do not turn continuously

On continuous jogging mode, while I am holding down an arrow key, my motor turns only for a little bit before it stops, and once it is stopped, the motor is still making the noise as if it is turning. Similarly, if I type in a G-code, for example X100, the x-axis motor turns only for a little bit before it stops, even though the reading on the screen is still changing and the motor is still making a noise as if it is turning. What is going on? Is it a setting/configuration issue or a hardware issue, and what correction should I do?

By the way, on step mode, when I hit an arrow key once, the motor does turn one complete step.

I am using Mach3 running in windowsXP, and I use a TP6560 4-axis driver board, 3 Nema 17 motors (xyz only) on a 7x7 zen toolworks kit.
