My 4x8 Plasma Table Build

[vacextar]

Well, this is what I have so far. Frame is pretty much built per Ron's drawings. Been plugging away at it evenings and weekends and now I'm just waiting on my package from candcnc to arrive so I can finish things up. Bought a computer off craigslist....P4, 2gb ram, XP Pro, 80gig hd, 17" LCD, keyboard & mouse for $120....thought that was not too bad.

Well I put 20 gal of water in for the first time tonite and only had one pin-hole to fix. I've got all the paint and primer for it.....just need to figure out how and when to get it painted. Can't do it inside my shop....was planning on doing it in my new addition.....but it is not heated and temps are supposed to stay in the 50's or low 60's for the whole next week. What to do?......

Close your eyes and paint it.......... I waited 3 weeks for weather, and it almost killed me. LOL
CNC withdrawal is NOT pretty!

Ok....I'm to the point where I've got everything hooked up and the motors all driving in the proper direction in Mach. What I can't figure out is how to get them to move the correct distance. In the MDI window, I can type in G00 X1.0......and instead of moving 1 inch, it moves over 5 inches. I see in the manual where it tells me how to calculate the numbers, but where do I put these numbers into Mach? Does anyone already have these numbers that work with the Precision plasma racks & 12 turn/inch Z, and Bladerunner 300-4 set-up?

Any help would be greatly appreciated! Thanks!

Should be in your configurations section.

Am I changing the setting in the motor tuning part where it says "steps per". Right now it is set at 5300......I tried changing it to a lower number and it reversed the direction the gantry moved.......?

Vacextar,
Look at your preciscion plasma blueprint, Ron has some suggested settings printed on it. If you cant find your print he has them on his site.

Doh! Thanks! That would have saved me some time. I did get everything figured out finally. Not exactly sure what happened the first time when I changed the number in the "Steps Per" box....but that's what threw me off. I calculated the number I wanted to put in there and when I went back to the MDI window and commanded it to move, it moved both slower and in the opposite direction from what it was moving before, so I figured I must be changing the wrong number. Messed around with it some more and....well, still not sure what happened that first go-around.....need one of those "palm to forehead" smilies.
