General Mach Discussion / Re: Backlash Compensation not affecting axis travel.

I hadn't even thought about that.  I've got a license, so that may be it.

I know about the 500 line limit, but is there a "list" somewhere outlining just what does and doesn't work in the demo version?

It would be a nice thing to have when testing with the demo version. Then a "potential customer" would know it's a demo issue rather than thinking it's a bug in the software.

Well, you've got me really curious now.  I'm having a hard time seeing how the Windows install could affect something as specific as backlash compensation and not manifest itself in other ways. Can you point me to the post you are referring to?

I don't know if it would be much less trouble for you than a Windows reinstall (or whether it would make any difference), but you could try downloading the older version of Mach that I'm using 3.042.020.  It's available via FTP.

I'm at a loss.  I just tried it on my machine (stepping at .001/step) and, when changing direction, my stepper jumps to take up the backlash amount I have set for the axis.

The only difference is my Backlash Speed is 75% and my Shuttle Accel is .02.

I do seem to remember problems with backlash in some older versions.  I'm using R3.042.020.  Which version are you using?

This may be too simple, but is the "Backlash Enabled" box checked?

I also have V19 and I use the basic Mach3_Mill post.  I didn't like the one "with_offsets".  It puts tool offset activation codes (tool radius if I remember correctly) and I'd rather put those in the code myself.

I don't remember seeing a Mach3_macro post when I got mine, so I can't comment on that one.

General Mach Discussion / Re: Elapsed Time output stopping during run

« on: October 15, 2010, 11:17:24 AM »

Thanks again Hood!

I don't think the look ahead problem you describe is causing my problem.  I was running the same program multiple times the other day and, on occasion, I would notice the the timer would be stopped at widely different times during the program run.  Sometimes the counter would be stopped at only 10 or 12 seconds.  Other times it would be stopped at 20+ minutes?

Like I said before, it's not a big deal.  The failure of the elapsed timer doesn't seem to be affecting any thing else. I'm just one of those anal types that likes to have a reason for things

Thanks for the reply Hood!

I'm not at my machine right now, so I can't say exactly what my look ahead value is.  I do know that it was set based on research I did regarding CV mode and I doubt I would want to change it.

I am curious why the look ahead value would affect the elapsed time counter.  In particular, why would it just stop?

I've recently noticed that, sometimes during the run of a program, the Elapsed Time counter will be stopped.  It will have a value, like it counted up to a certain point and then stopped.  It's no big deal, but it makes me wonder what's causing it.

I'm using Version 3.042.020

Anybody got any ideas?

General Mach Discussion / Re: F for feedrate

« on: September 04, 2010, 06:51:40 PM »

The short answer is no.

The long answer is that the feedate for each axis on a given mutli-axis move is the propotional amount needed for each axis to complete the move AND satisfy the programmed feed rate.  If you change the feed (speed) of only one of the axes, the you would change the path of the motion.....if that makes sense.

For the benefit of others, what was the problem?
