Trouble setting work piece to initial condtions was created by dansawyer
Good afternoon. I am manually writing g-code for a small cnc mill project. The machine appears to be in an unknown state, that is there are origins that are not visible to where I am looking.
First, what I am doing:
1. clear g54 using the machine window command (this adds the g54 value to the azis and clears g54)
2. home the axis(s)
3. use an edge finder to find the x edge.
a. find the edge.
b. use touch off to set the axis to -.1 (the half diameter of the tool)
4. repeat for y and set the touch off value to .1
5. run the progam (the first command is g01 x0 y0 f20
The result is the machine moves to x=0, y = some small - value (about -.3)
What could be causing this? Are there other parameters that restore from previous executions?
Where can I look?
Thanks in advance, Dan

Update:
I created a test program to test various commands and g codes. I am stuck with the following:
Based on an edge finder how to set G54 to zero and the x value to value .1?
The items tested include clearing G54 with the GUI and touch off. Both of those simply create G54 offsets.
How can G54 be cleared with out affecting the cooresponding value?
