Thanks, Hood. Now I know how to see what my other problem are when I use a sharpie attachment. It will help with the analysis.

Freehold, if it will pause the machine, is what I would like to see. All I have to do now is find what and where it is.

The machine is a PhlatPrinter. All axis' are driven by timing belts. The y axis as a 1:1 and the x axis has a ration, which I think, is 1:2. The y axis is a gantry and runs on v-grooved ball-bearings. The x axis are two rollers that are covered with anti-slip tape. They move the material on the x axis direction.

After reading all this I wonder why there is no 'pause' option. It's obvious that it could be a popular feature.

I made more test today.

With the machine on I jogged and set the dial to zero. I turned the machine off In Mach I put in x1 and x0. I turned the machine on the put in x1 and x0 and had nil backlash.
I turned the machine off and jogged in Mach. I turned the machine on and put in x1 and x0 and again, nil backlash.
I made the same procedure as in the first post, just to make sure it repeats it self and had the same result as in the first post.

I can't explain the problem and I don't know where to look for the problem.

It's a timing belt, Rich.

I never thought of making sure the belt made a full rev and I will check it out, and, BTW, I did splurge and bought a dial indicator, at Harbor Freight, on Sunday.

I found an oddity after I bought the indicator which I detailed in my thread 'coming out of jog error'. I wonder what causes that problem.

Yes, I've seen it, Tweakie, and it peeked my interest. I'll have to look into it since the x axis has a belt and it is very high tensioned. I may try to loosen it up a bit and see what will happen.

BTW, did you happen to see my post here? http://www.machsupport.com/forum/index.php/topic,19205.0.html

I jog back a little and then forward to take out any backlash. I set the dial indicator to zero and push the DRO button to zero it. I type the command x1 and than x0. The indicator reads about 70 for a backlash of somewhere around 0.03. I didn't touch anything, just typed again x1 and than x0 and the dial stayed at the same place, about 70. I did this a few times, the typing of the command, and the dial stayed at the same place.

I repeated the whole above procedure with the same results. Next I typed x -0.1 and than x0. Made sure DRO and indicator where on zero and typed x1 and than x0 and the dial stayed on zero, no backlash.

My question is: why coming out of a jog it gives me a backlash and when typing the commands I have no backlash, nil.

Thanks guys for the answers. I'll go through the procedures again and will come back if I don't get it solved.
