General Mach Discussion / Re: Z Axis Issue
« on: June 20, 2008, 05:30:10 PM »
Ok, thanks for checking, so maybe " noise " issue from some interferance on the cable traveling to the Z motor? Or checking my carriage again for any backlash or slop...? I was in the US Marines for 5 years so I would probably love the Army action ya have there. Been in a wheelchair for 20 years but I still love keeping up with the military stuff and going shooting at the range once in awhile.

As far as Tiger Woods goes, I'm glad he has got beat a few times, proves he is human and not a " Alien " from outer space here to take over the Golf world. His finish last week over 91 holes was a marathon I actually thought he would loose, think the play off thing of 3 or 4 holes would be better than making em do the extra 18 holes imo.

Well let me see what in hades can be causing my issue. Any list of ideas I should check you think? Where would you start? It runs great except for this issue LOL.

When I jog it on any axis it moves as intended, I can check any axis with a caliper that measures in thousandths and all seems fine, people have looked at the G Code and said it looks fine, but it cuts too deep on the Z axis 1st pass every time, if for instance the file has multiple depths to it, or layers, the 2nd, 3rd pass etc it does not add any " mystery " depth, but if I make a file where the Z depth is 0.00...it will still cut into the material almost a even 1/16th of an inch every time.  I have no tool offsets set at all that I can see or find, a friend who works with CNC's came over and helped me check all 3 axis with his calipers, we jog it any direction with MDI commands it does fine, when I cut a file, ask it to cut say a word, .0100 deep into a piece of wood, it adds a 1/16 to it..I am stuck lol...

Wave......

My name is Michael, I'm a wheelchair bound former US Marine. I live in Texas and have built a machine based off of the plans for a Joe 4x4 CNC Hybrid. It has a 4' x 4' cutting area, running Gecko 203v's some 425 oz Nema 23's and a CNC4PC Controller Board. I currently have a Hitachi 2 1/4 router on the machine. I will be making various plaques, yard art, and holiday decorations. Thanks in advance for your help and guidance to this new CNC addict :)

General Mach Discussion / Z Axis Issue
« on: June 20, 2008, 02:15:51 PM »
Hello all, thanks in advance for your help.  I am a new CNC Hobbyist, I have built a 4 x 4 CNC from some plans I bought. It is a Joe 4x4 Hybrid CNC if anyone has built one. Now to my problem, I am running Mach 3 Version R2.63, I have everything calibrated fine, I jog the machine with MDI commands on X, Y, Z and if I ask it to move G00 Z 1.0 it moves a inch, all great.  ???

Well when I output a file from VCarve Pro using the post processor of Mach 2/3 Arcs (inch) (*.txt) all is fine, EXCEPT on the first pass, it always cuts about 1/16th too deep. Always, I do not have any tool offsets loaded, I jog the bit to the top of the work surface, zero everything and run the file...1st pass is always too deep. If I make a file with say a 4" circle, pocketed 1/2" deep with a 2" circle pocketed 1/2" deep inside, the circles are spot on, 4" and 2" no prob, the depth of the 1st pocket is always 1/16th too deep, but the 2nd pocket, cut deeper as intended, is spot on depth wise....  ???

SO what would be causing the extra depth on my Z Axis? I hate to bother you all but am at my wits end.  :-\
 
I will post whatever files or screenshots that would be helpful, I just really need to tackle this issue so I can make this thing work right.  8)

Thanks again for your time.  8)

Michael Fuller
