Sccomp

[Randy Morton @ Clem Industrial]

I am looking at the new X4 Mpmaster.pst file.

 

Running a helix bore (or similar) with wear comp on, the output to turn on G41 is good. But the output to turn it off (G40) is not so good. It runs the G40 on an Arc move, which is no good for the mills we use here.

 

code:

---

....

Y.7016 R.7016

G40 Y0. R.3508 <-------- No Good

G00 Z.25

....

So, in trying to get the arc onto a seperate line causes a whole heap of issues in the post because the same callout, sccomp, is used for both G41/42 and G40. So if that gets moved/modified it affects both ends of the cutter comp system.

 

The code below shows how it turns it on from the MPMaster.

 

code:

---

pccdia          #Cutter Compensation

#Force Dxx#

if prv_cc_pos$ <> cc_pos$ & cc_pos$, prv_tloffno$ = c9k

sccomp

if cc_pos$, tloffno$

Any ideas of how to move this to a less conflicting line? Either one by itself, or one with a G1/G0?

If you check perpendicular entry you should get the G41/G40 on G1 moves instead of on arc moves.

 

HTH

I do have it set to Perp Entry (sound wrong said that way...lol). If I try (just for trying) to output without Perp Entry with wear on I get the big alarm pop up that Cuttercomp is being applied on an arc move.

 

Thus, it applies cutter comp OFF on the arc in and arc out. The way I have it, it is comping improperly only on the out move.

i use the same as mastercam guru , so the G40 output on the G01 line to return to the center (be sure to check "start to center"

Dunno why mine is different...

[gcode]

try this

perp entry off

start at center on

set entry/exit arc sweep to 90

Hey G,

 

Thanks, JP beat ya to it tho, just in an email instead of on here.
