Swissi,

I had the version 4 of your post processor working great for my machine. Not upgrading to 5, I am getting an error: Direction is not supported for machine configuration.

I have my 4th axis on the right side of my machine and use the X+ for the rotary axis in the post processor configuration. This seems to be what is causing the issue.

If I switch the rotary axis to X-, the processor works fine, but my axis turns the wrong direction.

Let me know what I am doing wrong or if there is an issue with this release.

Thank you for all your great work!

If I choose XY Positions at end of job and select G28 OR G30 I get the following:
G90 G53 G0 X0. Y0.

Shouldn't the G53 command be a G30?

I can't reproduce your problem. When I select a G30 X/Y position at the end of the job I do get the correct code.

The end of my job file looks like this:

Code: Select all

N96040 M9
N96045 G28 G91 Z0.
N96050 G30 X0. Y0. <----
N96055 M30
%
Can you provide more details about what exactly you are doing?

I figured it out.

I had saved a machine that was pointing to the v4 post processor. Apparently the machine definition overrides what's in the Post Process popup. It's strange because I deleted the v4 post processor. Maybe it just wasn't passing some of the variables.

I have a request. At tool changes and at the end of a program I would like to see the spindle shut off BEFORE the final retract in Z.

I'm changing tools manually so I'd like the spindle shut down ASAP when it's done cutting so I can open the door, get my impact wrench lined up, etc. As it is now the machine finishes the final cut, moves to safe Z, then shuts the spindle down.

I've made the changes to my personal copy of the post, but I'd like to see this change made to the newer revisions.

Would this mean the spindle would shut down while still in the cut?

I mean after the cut is completed. Currently it turns off the coolant, moves to to Safe Z, turns off the spindle then goes to the tool change position.

I’d like the coolant off, spindle off, go to Safe Z and then go to the tool change position.

It turns the spindle off 2-3 seconds earlier and I don’t feel like I have to wait for the machine to start my tool change routine.

There's usually a lead-out or similar clearance move before the tool is retracted, so I don't see a problem stopping the spindle before the G28 Z0. I've yet to see a toolpath where the last move leaves the tool in contact with the workpiece. Perhaps there are circumstances where that happens that I'm not thinking of.
