Help finishing mplmaster for haas live tool lathe

[370]

A couple of you guys helped me a while ago with my vf5 and now that i have that kinda working i started on the new live tool lathe. I know about the whole switching it metric and changing the c axis diameter in the control so it reads degrees per minute, but nfortunately i can't do that on this workcenter. So my issue is how the hell does one get real c axis feedrates out of mastercam for a haas. The control doesn't support inverse, dpm only works in metric, and i can't seem to find how to get the ipm feedrate to change along the toolpath. If i use ipm what would i set the caxis diameter in the control to? I've gotten good results out of g112 but that requires i edit the hell out of the code and lie to it, i have to post it out in g17 right side plane pretending to use the y axis as haas uses x and y for face interep instead of x and c, i think given enough time i could figure out how to flip the c to y it's gotta be in the g112 area somewhere, but then also need the x values to go back to radius instead of diameter as x diameter in g112 on a haas makes a whole lot of unrecognizable scrap, but it can only do that during the g112, it still needs to be in diameter for the initial positioning before the g112. if i could just get the c-axis feedrate figured out i could say to hell with g112 and be done with it. forgot to mention it's x5 mplmaster and i have almost everything else fixed already unless i'm missing something, g76 is fixed, mcodes are fixed, p live tool adress is fixed, drill retract height is fixed, comments that were to long is fixed, machine rpm limits and travel limits are fixed, it's just down to c axis feed, and the radial drill cyces but not worrying about that yet. I'm kinda proud of what i've got so far, been using it as a learning experience and just want to finish it off. thank you in advance.

ok i got the c for g112 changed to y( that was easy after i ctrl-f'd it), still need to find the x radius tho, and i will need to fix the c feedrate yet because it doesn't have g107.

ok g112 is good now all i need is that c axis feedrate for all non g112 c axis movements

I'm working on Haas c axis post too. I started with Generic Haas SL 4X MT_ Lathe post. I think is less ediths needed.

i wouldn't know about that one i've just been funning around with the mplmaster. it really is a decent post once you change a bunch of stuff, a lot of the changes were simple remove a # here, change a variable there. I've asked haas WTF they won't let you change setting 102 to 114.5 when working in standard units. If i could flip the machine to metric i could just feed in degrees per minute and be done with it but NOOOOOOO. Oh man it's late, at least using the g112 i can get it to change feedrate that way but anything else is just straight not gonna be right if i use the C. Do you have any issues with your post that maybe i've already fixed?

I have a few issues but right now I have no time to do it. But the Generic Haas SL 4X MT_ Lathe post is the one comes with Mastercam.

For Haas live tooling you need to have IPM feed rate.

 

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

 

force_ipm : 1 #Force IPM output for all toolpaths

 

find this section in your post and add " force_ipm " to the line

 

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 <----------- add " force_ipm " to this line

else, pfclc_deg_inv

the problem is that the ipm feedrate is not interpretted correctly by the control. if yo program 20ipm it moves the same speed wether you are on a 1"daimeter or a 10" diameter all based on what you have set for the c axis size setting. if there is some way i'm supposed to go around that, that i don't know then that would do it to.

also instead of changing it in the post i just set the op defaults that way through mastercam so i can still turn in in/rev.

Which line did you fix in the post to get your resutl
