The lathe post processor  I used in Fusion has the following info when opened:

The following is the directory of where Mach3 Turning CPS files are  located on my computer:

C:\Users\user\AppData\Local\Autodesk\webdeploy\production\890691bd91ea0296c1b94572fdc7dda4ba2e48f0\Applications\CAM360\Data\Posts
---------------------------------------------------------------------

Note that I did modify the CPS file to remove unwanted code that it generated and frankly you really need to know how to do and  what to look for.
There is an "hour long video" on how to modify a post processor, but guessing only that video was on You Tube....so could be wrong.

Sorry, but, it's been over a year since I used Fusion.
RICH

Thanks, slightly different, this is the current one..

I will seek the video and have a look. It would have been handy if the Autodesk guy said where the problem was

Ooh, exciting 

Managed to successfully edit my post, it now outputs what i want, instead of G28 X.. Z.. it checks the post properties for "G53 home" values, if i enter one i then get G53 X.. Z..

Sounds simple but took a few hours to learn what does what and where to stick brackets etc 

The post had the G53 bits but was not used where i wanted it, just for a parts-catcher 

Just got a reply from CS-Labs regarding G32...

N22 G32 Z-29.816 F1.5
N23 G32 X10. Z-30. F1.5
 
You can't use two G32 commands one after another. You have to divide them with G0 or G1 command.
The limitation is caused by Mach3 construction.
Mach3 wasn't originally adapted to the G32 function executed by an external controller. We made it possible but with the above limitation.
 

That explains a lot i think, i don't know if adding a G0 in the code will affect things or if its better to stick with no taper at the thread end???

I'm setting up my servo drive for the 4th axis, I have not fitted the ENC module yet - should i be able to run the motor without the ENC module??

The drive will lock up as expected when enabled but i cannot get any movement at all.

The manual is vague on servo spindles and I have no idea of what to set and where - ports & pins, motor tuning, CS plugin etc.

The 'net seems just as vague as well

Any chance someone with a CSMIO IP/A controller and a servo spindle could enlighten me as to what settings i need and where please?

If the post comes, i'll be able to fit the ENC module but i thought that was only for sync when threading??

you can run spindle without ENC module.
you have to set analog Output in CSMIO plugin config.

see chapter 10.6

btw witch servo Controller are you using?

Yeah done them, i'll go back out and re-check though.

Do you have to enable Spindle DAC as well as spindle axis? The manual shows both which seems a bit odd as i thought the DAC was for 0-10v VFD outputs?

Do ports & pins plus motor tuning have any bearing at all???

btw witch servo Controller are you using?

AASD Chinese from AliExpress

are you running this Controller in step/dir mode or 0-10V analog mode?
