Help with Generic Haas SL 4X MT_ Lathe post

[MSL]

Hi all,

My post is outputting inverse feed for C axis. How can I change it to output IPM when I'm doing live tooling. This is for a Haas ST Lathe. I started with Generic Haas SL 4X MT_ Lathe post.

Thanks.

Ara.

The MT_Lathe posts are setup to output IPM or Degrees per Minute. They don't output Inverse Time. (So what you are seeing is DPM output).

 

To force IPM, I added a switch variable to the top of the Post:

 

force_ipm : 1 #Force IPM output for all toolpaths

 

Then in 'pfcalc', add that variable switch to the logic statement:

 

pfcalc		  #Feedrate calculations, gcode 0 does not evaluate
  if abs(c_wnd-prvc_wnd) < vtol$ | c_axistype = three | drillcur$
  | ipr_type=zero | prv_pnt_at_zero | gcode$ = zero | force_ipm, pfcalc_u_min
  else, pfclc_deg_inv

Hi Colin,

My bad, My Generic Haas 4X MT_ Lathe post outputs degrees per Minute.

Haas requires IPM for live tooling.

By the way, your class is awesome. lots of good information.

 

Thanks. I'll give it a try.

Thanks Ara. Let me know if adding that condition doesn't work...

Hi Colin,
