Fanuc 4-axis without inverse time

Trying to either figure out a way to make this simul 4 axis post work properly or maybe there is a way to use feed per minute? The code seems to work fine when "F" is reading in the thousands but as soon as i get to a low feed, in this case F85., it is just so incredibly slow. What am i missing here?

Try the attached Fanuc PP, might work for you but as you have not uploaded any file very hard to diagnose anything !

So with some post modifications we got it to work. The only issue is that the codes continues past A360. instead of rolling over to A0. Any ideas here? It's all fine until the machine hits A9999.99 and alarms out with "Too many digits". The machine is reading absolute and rolling over but the code doesn't show that.

What did you change and why ?

 

Generating a Rotary toolpath here the G code does not go past A360, every full revolution it goes back to the start.

See attached example file and the Post Processor used.

This looks like its solved but ill have to run it. Where did you get this post? The only one i see is Inverse time which just runs on past 360 degrees.

This doesnt seem to be working now that im running it. The feed is extremely slow. Also, though i have to look through the code, the tool just ran through the part mid program. Last post ran the part complete but ungodly slow.

What settings do you have in your tool "cutting data" ?

What do you have your Units set to in Manufacture, must be in Inches, the PP will output the G20 (In) or G21 (MM) depending on your Units settings
