Post Processors for SZGH-CNC990TDb

Is there a post processor for the SZGH-CNC990TDb CNC controller for the Autodesk fusion 360?

It appears to be a clone of a Fanuc control, but we would need to see exactly what it needs for code. Do you have any proven g-code programs you can share, or even a digital programming manual for the control?

If those are not available, I'd suggest starting with the Fanuc Turning post processor

This is a new Chinese controller.

Looking at the manual provided, I'd suggest starting with the Fanuc Turning post processor. It may require some final tweaks to get the code accepted by the controller, but we will have to cross that bridge when we get there

Is it possible to damage the machine if I use a fanuc

1) Turn your rapids and your feedrates way down

2) Set your work offset well away from the part

3) Keep your finger on the "feed hold" button.

For the most part, g-code is g-code. While the industry takes great liberties with what is considered "Standard", there IS a somewhat base standard, and that's RS-274 code. Fanuc, Mach3, Haas and other controls are based around this language. Looking at your manual, this also appears to be based around that standard. The worst that "should" happen is that it alarms out on some line of code.

Again, set it off the part a ways and run slow

Did you get a PP for the SZGH control?

I have altered the Fanuc one to suit my needs and it seems to be working fine for me as the standard Fanuc one is close.

Threading needs a bit of tweeking, I added a section to select the correct gear depending on the spindle speed. I also changed the G28 moves as I prefer to move to a known G54 position which I can set via the User Properties tab.

Oh BTW mine is a CNC1000TDC but I think the G Code is the same.

No, I have a postprocessor for this controller for the Siemens NX software

If you can edit the postprocessor to be fusion compatible

This is the PP I altered to suit my CNC1000TDC, it may or may not work for you but I think it should.

I also edited out some of the lines I added because they are specific to my lathe (gears) and to the way I work (tool call and move at end) and you will likely not need them.

Note that there are quite a few user properties I added that need to be altered to suit your lathe, for example the ones with the red star. The ones with the blue star are ones I have just edited out as they were the position for a final move at code end and likely you will not use them.

I also edited the lines at the start of the code to show tool comments as they are more useful to me than the info that was previously displayed, so if you have comments in your tools like the image below

It will add the comment to the code like below.
