Hi Aciera,
See replies by your questions
When you get the 35mm offset in X after G54 G0 X0 Y0 does the DRO show X 0 or X 35? **Shows 0 , Have to go G0 X35 to go back to original position**
Try this: MDI command G54 G0 X0 Y0. If it does not move to the center (ie you get your 35mm offset) do MDI command G92.1 (this removes all G92 Offsets) and try G54 G0 X0 Y0 again. ** No change to position or DRO values**
Note what is happening in the DRO for the X axis does it read 0 or not.
[edit]
Maybe also have a look in the linuxcnc.var of your config and check that parameters 5211-5219 are zero. ***These are all zero. Only 5221-5223 have values***
Attached are a few more screenshots. The following is the order of actions before taking each screenshot.
Started Axis program
homed all axis
G54 G0 X0 Y0 to get back to where we had been experimenting
Touched off each axis X Y Z just to be sure.
Screenshot F
Started file executing. Machine moved to the wrong start point
Stopped execution after 2nd corner
Screenshot G NOTE the TLO X: -35.707. This is the same value that shows in the bottom of the radius error messages I have been getting.
G54 G0 X0 Y0
Screenshot H
G54 G0 X35 Y0
Screenshot I
Touch off X
Screenshot J
Opened file again – Display stayed the same as J
Started file executing. Machine moved to the correct start point
Stopped execution after 2nd corner
Screenshot K (DRO values for all the G54 lines and TLO lines stayed the same)
What does TLO X: stand for?
The versions of software I have are Xfce 4.8 and Axis 2.7.0

Hi
first you shoudt realy update your linuxcnc system
in Terminal
sudo apt-get update
sudo apt-get install linuxcnc
the TLO stands for TOOL_Length_Offset G43

Aha, do you have a tool offset in the tool table for tool1?

no
Tool1 is in most cases the ZERO tool
you only need this if you got a ATC or a FIXED toolclamp system like BT40 MKxx to change different tools
otherwise you need to mesure by G38 your tool after changing in the programm
or do a Programm for eatch tool
there are multiple ways to get things going

I dont use the AXIS GUI but the user writes that he has a problem with an offset of 35mm in X that should not be there and, well, i see that tool1 is loaded hith a TLO X of -35.707 in the screenshot.
So I would assume that there is an x-offset in the tool table for that tool and maybe that offset should not be there.
[edit]
Also I see that this tool has a z-offset of 0.511 and a diameter of 0.125 which I think is why he is getting the arc error.
So IMHO the values in the tool table might be the problem.

Please explain more. Are the possible tool off sets in the Fusion tool setup, or is there tool off set settings in Linux.?
I see in Fusion I have not been using the tool number system and all my tools start with 1- then the description
"So IMHO the values in the tool table might be the problem." what is IMHO?
Sorry I am ignorant on a lot of these things
Thanks

Linux = operating system, so it has no offsets
LinuxCNC = machine controller that runs on Linux operating system, Has tool offsets, machine offsets, etc.
IMHO = In My Humbled Opinion
Tool offsets can be seen and edited in the "File>edit tool table", menu in Axis GUI

"IMHO" means "in my humble opinion"
In LinuxCNC there is a tool table where you define the different tools:
linuxcnc.org/docs/2.6/html/gcode/tool_co....html#sec:tool-table
I'm not near my machine and I'm not really familiar with the axis GUI so I can't check how to open it at the moment but you might want to look in the LinuxCNC menu bar.
Maybe the "Machine"-tab.

Thanks tomy you write faster than I do.
