When looking at the G code for the file I’ve programmed, the initial Z indication(G0) is .750" but my toolpath input for the initial Z movement is .040" so that’s what I expected. However, the first Z movement was .750" and I can’t figure out where that number came from.
I designed and created the toolpath using Carbide3D and I’ve saved the Gcode in both .nc and .tap for use in Mach3.
I realize that I can edit the G0 to what I want (.040") but I’d really like to know is, where Carbide3D is getting that G0 of .750" ?
This one has me baffled…any suggestions would be appreciated.
Good morning Will, thanks for the reply…
Here is the file. I hope the attachment is ok, otherwise I can send it as a txt file. : TMW-L-R arms_v02-CRASHED.nc (67.0 KB)
I’m using Carbide Create…into Mach3…for a Taig CNC.
I think I have found, at least, part of the problem. I now think the the Z distance is correct since the .750" is a positive number and means the end mill is above the work piece, not plunging into it.
What I have found, that is not correct, is the feed rate of 20.0 ipm. I think that is WAY too fast for
the 1/8" x 1/2" end mill I’m using. I thought it was more like 8 ipm…not sure how it got to 20.0 but will fix it and test-run the program again.

Just a quick report to anyone following this thread. I think I’ve got it all solved now.
I had 2 toolpaths in the ‘Groups’ box and did not ‘disable’ the one I didn’t want to use. Not sure if that caused any of the issues I was seeing but something I learned.
I was not using the proper Tool Selection and Tool Edit procedures. Video tutorials helped me solve my problems.
In the final analysis, my use of the ‘Tool Library’ seemed to be most of my problem.
Will…again, thanks for your reply to my call for help.
