If you have Dewey's gui embedded into Axis you can just press any axis key and it enters the current value. So you jog up to a start point then press the axis key and it enters the value. John

Rick G OFFLINE Moderator Posts: 1069 Thank you received: 15 Karma: 80	John, Sort of a G71 with a gui? If I have a finish path for a part that I want to run I am setting a start position to work down to it by the entered maximum cut per pass. I am re setting the machine position with G10 each pass until done. Been up about 4 hours now. Rick G

BigJohnT OFFLINE Administrator Posts: 4944 Thank you received: 85 Karma: 134	Been up 3 here lol. I think I understand... if you have a profile you cut the profile at the start OD then increment it in by "depth" until the last pass is at final depth? Is G71 a roughing routine or something like that? John

Rick G OFFLINE Moderator Posts: 1069 Thank you received: 15 Karma: 80	Exactly. Does the same thing as your od sub but a more complex shape is possible that is contained in another sub. I believe G71 is a roughing routine in other interfaces and I believe someone might be working on it for EMC. Rick

I just did some googling on G70/71 and I think something like that is possible and desirable to have. So instead of the OD turning part another subroutine with the profile is in the middle...

G71 subroutine for roughing using cutter comp and G92 offsets for X leaving a uniform amount of material for finishing and calling the "profile" subroutine for the path to follow.

G70 subroutine for finishing using cutter comp and calling "profile" subroutine with the finish tool.

If you embed Dewey's GUI into axis you can combine subroutines to form a complete g-code file. So you can go to the G71 Tab and fill out the blanks and insert it then go to the G70 tab and do the same. Then "finalize" and run.

Is this what you had in mind?

and I thought today would be slow and easy...

That makes sense, I did not even look at the finish run but that would be perfect.

I have not embedded Dewey's GUI yet as the machine that runs the lathe has no web access, but will soon.

As a matter of fact I am building a new shop here and am going to take advantage of the mild temp to run some wires an insulation today. When done I will have much better access for all the machines.

If you get a chance can you try the files I sent you?
