The line can be ' G91 G28 Z0 M6' for a tool change on a automatic tool changer or 'T2 M6' for a manual tool change.

G28 needs an axis designation e.g. G28 Z0 or G91 G28 X0 Y0 Z0

It sounds as if your touch plate thickness is set at 2" thick

Select the item in the menu tree and click on its properties, there will be a list with height, width etc, just enter new values and press enter.

Hi TomR,

are you using a licensed or the demo version of Mach3, the Demo version has limitations.

The red high lighted block is the problem area, if you are moving from one fixture to the next you do not need to go back to xyz zero.

Just add the fixture offset to the first move line of the second/third fixture code.

The code looks fine, if you remove the G91 G28 Z0 & G28 X0 Y0 A0 lines that will stop it going to machine reference at the end but there is nothing in the code to make it dive into the table.

That would be the sensible thing to do but you can use any offset with any tool.

H0 & D0 should be more like H1 D1 and are used along with G41, 42 & 43

G43 H1 sets the tool height offset to offset 1 in the tool table. Hnn can be in the range of 1 to 254

G41/42 D1 tells tool compensation to use diameter offset 1 from the tool table to adjust the tool path by the rad of that tool offset.
