Mach3 and G-Rex / Re: Mach 3 Backlash problem

« on: April 27, 2011, 09:41:02 PM »

Hi Rich,

Thanks, I am pretty sure that the steps are fine because the machine was working fine before I changed computers, I checked the Y axis and it is not binding, I can turn it all the way to the front and all the way back by hand and it is not sticking nor is X.  With the backlash on I am getting a squealing sort of sound with it off I don't, I'll need to recheck the amount backlash.. I tried to cut a circular ring with .2855 ID and .400 OD and it's not perfectly circular the ID is 0.273 and OD 0.418 it looks sort of slanted on the perimeter...? I did recently tram the machine but it was within a couple thou all around so I don't think it's the tram, I've increased the shuttle acc to .05 seems to help with the squealing and a tuned down the steppers but the main thing is that it's not cutting anything to within acceptable tolerance?

Mach3 and G-Rex / Mach 3 Backlash problem

« on: April 27, 2011, 10:41:46 AM »

Hoping for some help to get back up and running. I was running ok but decided to upgrade to a faster CPU I am running windows XP  mach 3 version (Mach3 R3.043.022 ) the motors were tuned before to 154 velocity and 20 acceleration... without the backlash on I get no weird sounds but with it on I get this:

and my parts are not measuring as per the drawings for example a .304 hole turns out to be .293...

Really hope someone can help, not sure what ether relative info needed but shoot away, I am also still relatively a newbie

Thanks,

Mach3 and G-Rex / Mach3 Probe Emulation Need Help

« on: March 03, 2011, 06:06:18 PM »

Help!

I have been trying to get my homebuilt probe working for some time without luck, I am sure I now have the wiring right but the probe routine doesn't work.  I have reverted to testing by using a key to simulate the probe tripping under inputs using emulation,  however I tried assigning P and when I press the P key the led does not light up?  Anyone have this problem? I have also tried other keys same problem?

Thanks

Finished Screens / Mach Blue Probing by Big-Tex

« on: February 19, 2011, 10:05:54 PM »

Hi All,

I am in the process of trying to get my homebrew digitizing probe working for my mill.  I have made the probe using "cognitive inovations" instructions...now I need to get a screenset with the probe script..on Artsoft's home page under screensets the Mach Blue Probing by Big-Tex is available, is this file working as is or would I need to edit anything?  I was reading this thread on the Zone:
http://www.cnczone.com/forums/mach_wizards_macros_addons/56079-xyz_probe_modification.html

On the first page are the directions but the last link doesn't work...just wondering if anyone can confirm the file contains all of the modifications or is working...I would prefer to use the original Mach screen as I have gotten used to it, any advice would be welcome..

Thanks,
