General Mach Discussion / Slaved Axis pitch diameter difference

« on: November 21, 2010, 08:24:52 AM »

I have a rack & pinion gantry that has a 10’ travel on the "X” axis that is slaved. If the pitch diameter on 1 of the pinions wears a few thousands more than the other and you have 10’ of travel the gantry ends up out of square the farther you get away from the home switch. Is there a way in Mach to comp for 1 side of a slaved axis traveling slightly different than the other on a slaved axis?

Thanks

General Mach Discussion / Smooth Stepper & Backlash

I thought Smooth Stepper was going to have an update for backlash a year ago? Sure would be a good option.

There was a post a few weeks ago stating that progress with the backlash option in SS being close to complete. Any updates?

General Mach Discussion / XP Home Setup

« on: September 22, 2009, 03:27:26 PM »

I am getting ready to install Mach3 for the 1st time for a machine using XP Home SP1. I have Mach3 installed on a PC to tinker with it to learn it. Are there any tips for setting up XP Home up for a machine? I am not going to use Win Update & will not use the machine for ANYTHING but Mach...No internet connection or other any programs. I have an 8GB solid state drive.

Thanks

Hood:
Since you have a pico with a SS do you use backlash comp?

What BOB's are good with the SS?

Do you use the C23 BOB.

I am updating a gantry & was wondering if the HOME SLAVING smothstepper problem has been fixed.

General Mach Discussion / "X" travel on gantry question

« on: August 16, 2009, 09:07:55 PM »

I am replacing an DOS 486 system with XP & Mach3 & have a question.
 
We have 120" of travel on our slaved "X" axis steppers with rack & pinions. If the pinions wear at a different rate than each other (which is common) at the end of the 120" travel we get an accumulated error making the "X" slightly out of square. To mimimize or split the error we manually square or "HOME" our "X" axis at the 60" or midpoint point of gantry travel which helps split the acculated error. We don't have "HOME" switches now but will eventually like to install them with Mach3.
 
Question....
1) Can I set HOME manually like we do now with a screen button while in the center of the "X" axis travel?
 
 2) When I get a little farther along with the retrofit can I set "X HOME" with optical switches in the middle of the "X" axis travel??? I don't think I can have a mechanical "HOME" switch in the middle of the table with the gantry continually traveling back & forth over the "X HOME" area.
 
3) Will Mach3 allow a total axis travel setting using a negative from "HOME" on one side in the parameters?
 
Thanks

Ron:
Did you get your screens the way you want them? I am setting up a retrofit for our waterjet & waterjet screens are needed.

Thanks
