Cannot tap a hole using the drilling tool

Hello, 

 

I'm having difficulties to post my tapping-job to our Quaser MV154P 3-axis CNC machine. 

Whenever I posted a NC-job, directly created within Fusion360, I would get a error message that said G5.1 Q1. 

I then opened the NC-file, and deleted the G5.1 Q1 lines and G49 lines. 

Now the machine swallows the program, but now I'm having another problem. 

When I start the machine, it runs at normal feedrates until about 3-4 mm above the part. Then it stops and it very carefully drives down the holes. I can't figure out where I'm having the problem. 

 

Attached is the postprocessor im using. And here is the G-code:

Any tip or help would be greatly appriciated. 

 

Best regards, 

Christian

Hi, I noticed that on the old generation machine I used before, the line had to be G5.1 Q1 at the beginning and G5.1 Q0 at the end. I haven't had a chance to try it in the manual, but can you test it this way?

It looks like this post processor hails from 2014 or so. There have been many changes to our posts over the years, and it's likely that something was changed on our side in the last nine years or so..

You have hardcoded smoothing commands, they should be disabled for drilling and probing routines. A new post processor would get you better code I suspect.

OK, I found a Post processor in another topic, which is a bit newer. 

I edited the cps-file to accomodate air-cooling (not through tool) and I disabled the smoothing command, and now everything runs smoothly so far - we havent noticed any trouble (yet) 🙂  

I have attached the post processor.
