Setting up Home & Limit directions

[widgitmaster]

Thanks again Gerry, that video helped get me started!

It's awsum to hear those steppers whine while moving the axis!

I'd consider all those videos mandatory for anyone using Mach3.

I agree Gerry; however, there doesn't seem to be one for "Motor Tuning"

I have a 5 TPI ball screw for each axis, and 200 step/rev motors.

In "motor tuning", I have set:
Steps Per to 1000,
Velocity to 250,
Acceleration to 75
Step pulse to 4
Dir pulse to 4

I'm not sure if it is optimal or accurate!

If you're microstepping, multiply the amount times the 1000 steps. For example, 1/8 stepping would be 8000 steps/unit. 1/10 steps (Typical Geckos) would be 10,000. Velcocity and Accel need to be determined through trial and error. Find out the fastest they work reliably and then back off about 20%.

How do you define the home postion in Mach 3. Not to sure how the steps are to define the home. Any suggestions would be helpful.

Is there a video for the Mach 2 version. I have been using Mach 2 flawlessly for two years now and due to a complete computer crash and the resulting new computer, I've downloaded the current offering of Mach 2 which is a newer version that I previousy had. I'm having trouble establishing my machine home now and need some help. Any ideas?
Thank
