Quick question about 3+2 and probing on a Haas

[Kyle F]

Hey everyone, one of the machines I program for is a Haas UMC-500 and I regularly use our renishaw tool probe to pick up work offsets.

From there I'll use a typical g254 dynamic work offset to access various other planes for 3+2 milling.

I recently got CIMCO probing and it's been incredible, but I had to get a few post modifications.

First issue was that my post was outputting a "S0 M05" line so I got the S0 removed, no problem.

Second issue was an alarm of "TCPC OR DWO IMCOMPATIBLE CODE" caused by G254 being active when it tries to start the probing cycle.

To get it to work all I had to do was hand delete the G254/G255 and all was well. I relayed this info to my reseller and they modified my post. Now I can post the program fresh out of mastercam with no hand edits ( exactly how I prefer lol )

So my code looks like this:

N1 (OPERATION - 1)
(PROBE 1.84 BORE FOR X0. Y0.)
(STANDARD OMP40_A-5000-3709)
G0 G17 G40 G80 G90 G94 G49
M11 (UNCLAMP B)
M13 (UNCLAMP C) 
G0 G90 G53 Z0.
T47 M6
T1
M05
G0 G54 G90 C0. B0.
X0. Y0.
G43 H47 Z2.73
M10 (CLAMP B)
M12 (CLAMP C)
G65 P9832
G65 P9810 X0. Y0. Z2.73 F50.
G65 P9810 Z.8819
G65 P9814 D1.84 S1.
G65 P9810 Z2.73
G65 P9833
G49
G0 G53 Z0.
M01

 

BUT it got me thinking, what if in the future I want to use G254 to reference locate a datum or feature and probe at something other than B0. C0. ?

so this morning I added a quick probing cycle to check a feature at a plane and the code outputs like this:

N2 (OPERATION - 2)
(STANDARD OMP40_A-5000-3709)
G0 G17 G40 G80 G90 G94 G49
M11 (UNCLAMP B)
M13 (UNCLAMP C) 
G0 G90 G53 Z0.
T47 M6
M05
G0 G54 G90 C-90. B30.
M10 (CLAMP B)
M12 (CLAMP C)
G254
X2.38 Y-2.6447
G43 H47 Z3.8201
G65 P9832
G65 P9810 X.0896 Y-.8728 Z1.5 F50.
G65 P9810 Z-.1181
G65 P9823 A105. B180. C-105. D.7561
G65 P9810 Z1.5
G65 P9833
G255
G49
G0 G53 Z0.
M01

Which leads me to believe I still need some tweaking, cause I imagine I'll get an alarm from that G254 being active.

Long story short, I am unsure exactly how I should ask my reseller to modify the post for when I'm probing at an odd plane. I've never had the need to do it honestly but I'd rather have it sorted *before* I need it so I don't get hung up waiting.

Is it as simple as adding a G255 before the probing cycle, and then re-activate G254 after probing is done? or even maybe not re-activate it at all and just make sure I do forced tool changes between probing cycles if there is ever more than one in a row on a certain plane?

I posed this question to my reseller when they were modifying the post previously but they just kind of ignored me LOL so I feel odd asking them to "fix" it when I don't understand the mechanism of how.

I'd appreciate any input or advice! Thanks y'all

Dude I run into this as well the probe will not run in 254, its not cool. 

I have used incremental movements once I set up and turn the probe on. Not real comfortable with this but it works. I'll be following to see what more experienced minds do. There gotta be a way right. 

 

Sorry this isn't a solution just an affirmation that its an issue.  Good luck ill keep tabs.

I honestly think it may be as easy as just deactivating with G255 before the first G65 probing cycle. After the probing cycles it's just homing the machine via G53 so I can't see that posing any problems.

Between my next setups maybe I'll give it a try and report back.
