Title: Z height unstable
Post by: antennas on September 09, 2014, 02:47:33 PM

Good day folks. When I set the Z either using AUTO ZERO button or manually, it doesn't seem to "remember" it. So many times I Have set the Z to zero then ran the code and it plunges into the work or sits and moves around in the air.
What gives?? Am I missing a setting or something??

MACH 3  Version R3.043.066  is what I am using.

I would love to fix this.

1) Is your zero actually being set correctly?

2) Is there anything in your g-code that can alter Z zero? (G43?)

Well I use an auto zero script from this forum and sometimes when I set it manually it does the same thing. I'll look for a G43 code. I have Aspire that makes my G code.
Thank you Gerry.

I think I found something.

N130 (V-Bit {60 deg 0.5"})
N140G00G43Z0.8000H1

that is some G code from the beginning of the file.  Is that what you meant about G43?? If so how do I stop it from doing that??

Do you have a tool length for tool #1 in your tool table?

All my bits are tool 1 it would seem. I looked in the tool database but is there somewhere else?
