Hi Folks,

Some help would be most appreciated.

TCC v3 seems to add the following code between tool changes:

G91 G28 Z0. M09
G28 Y0.

Particularly the g28. At the moment I edit this out after generating the g code file. How else do I stop this happening. Have I missed something in "settings"?

Secondly it seems that I can't edit this code in the g code window. I can only edit the G code when a single operation is highlighted and then the offending code is not visible.

Any pointers in the right direction would be great.

I am New to TurboCAD but not G-Code.

This G-Code is used to return an axis to the home position for tool change.
Ex. G91G28Z0M19
G91 Incremental Motion
G28 Home
Z0 Z postition Home for ATC
M19 Origin Spindle

Usually after a tool is finished being used one would send it home in the Z axis and sometimes Y and Z to change tools on some machines.

Is the TurbCad post sending a tool home before you are finished using it? Like maybe when you are doing a pocket in steps or set D.O.C.?

This may be a simple fix in the TurboCAD Post.
