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

« on: November 10, 2010, 11:08:35 AM »

Just received this message from Brian:

"The Backlash is not working with the SS at this time. Greg was here about 2 weeks ago from Warp 9 and I made the code to do back lash for him. So you should have it very soon!
Thanks
Brian"

I forgot to mention that I am using Smoothstepper.  Bill and Hood, I hope I didn't make you chase your tail on a bug you knew about already.

Thanks for help.
Eric

To try an older Version, what files do I need to save to 'carry over' from one version to the other?  I know there is an xml 'settings' file.  Anything else?

Thanks guys for your help in looking into this.  I can't seem to find the thread about 'reinstalling windows' but I believe it was RICH (my apologies if not) who was helping a client or two.  I read through so many that they all look the same now.

However, I did just find this post.  I will try this and see how things go.

Just to assure you, I did pay for a license.  Brian actually came and helped with the setup of the machine (Thanks again, Brian!).  Also, I said it was a retrofit, but it was more like a brain transplant, just the computer/controls were updated, and original steppers are on machine.

Thanks for your help Bill.  I tried your speed/accel settings but that didn't do it.

Version: R3.042.040 (Ha, 'demo version'...still waiting for license file, or IRS, to come to me.)

I must say I saw a post that had a solution similar to mine, and was fixed.  Unfortunately the solution was a windows reinstall.  I'm hoping that is not the way to go.

Ha, I was supposed to say "I tried both", which I did.  Yes, it is currently 'checked on'.

Also, My current settings:

z-axis: 0.004
all other axis: 0
Backlash Speed 20%
Backlash Enabled: checked
Shuttle Accel: 0.05 sec

Thanks.

Hi Folks,
I've been searching for a few hours on this forum looking for the problem I have, but none seem to work for me.

I have ~0.004" backlash in the z-axis, but after entering value and restarting Mach3, the milling machine does not respond to the compensation. The values are 'saved', and I have tried different Backlash Speeds, Shuttle Accelerations, axis, and even different compensation numbers.

I have an indicator setup, and step the axis in 0.001" increments, when reversing it takes 4-5 'steps' to register movement.  Also the machine is a retrofit, and with previous software I could here extra 'steps' the stepper would take as it reversed, but have not heard that noise, even when trying different compensations values on different axis.

Does the compensation only work when a toolpath is running?

Thanks for your help.
Eric
