I have also done this earlier this week. Have you tried this with tool radius compensation as well? G41/42? Had some challenges with that and R180....

I missed this:

Right so called up G10 L2 P06 R180 and it tells me " invalid parameters in linear command"
And "linear move on line 13 would exceed Y's positive limit " And I dont have a Y axis ???????

I believe for that you need to set up a dummy Y axis in the INI file. So maybe you can give that a try before we start going down the kinematics path.

Thank you for that Aciera . All sounds interestig but not sure yet if this is within my capabilities . Give me a bit of time to "read mark learn and inwardly digest" as an old schoolmaster kept trying to drum into me .

Meantime sounds likes Joekline9 may have succeeded in what i am looking to do.. Please excuse me while I look a little deeper into his solution

I did try to set up a Y axis because software was looking for it .
I copied X axis with similar limits , but could not open Gmocappy after that without error report .
Clearly my Ini Y axis was not acceptable
any pointers would be appreciated .

X and Z were originally set up using Stepconfig.

Unfortunately I cant do that Aciera. as I had to delete the changes I tried , in order to progress with other parts of my project.
I could try to replicate them by making another attempt ?

or (thinking aloud) maybe I could see if I could do a stepconfig for a lathe with Y axis in order to give me some clues on a lathe with X,Y,Z, but from memory stepconfig for a lathe only permits X and Z.

Maybe a simpler option would be if joekline9 were prepared to share those elements of his INI file which make this work for him

Right
So I seem to have managed to create a dummy y axis
Included the rotate command before the threading tool change and  clearly  the threading cut has gone to a front tool position on the screenshot  but restarting at line 134 bring up the errors shown

 

Clearly I need to do something to overcome this Y axis error.  Does this axis somehow need to be included in the homing process  and if so how?

Will post ini and hal seperately
