Sorry for the late response. And thanks for your help. It's greatly appreciated. To understand correctly the U. In my above post with my probed P1 to P4 the biggest difference is P1 and P3 at 27 thou. So if I had a U 0.02 that would have generated an alarm. Yes I have a printed copy of Inspection Plus manual at work and a copy on my home PC. I need to read more and experiment. We build subway and street cars for mass transit. We have a big SNK 5 face mill. When they machine the truck frames they always have so many issues and some failed inspections and then the truck needs to be reloaded and fixed. Pain in the xxxx. The SNK has a spindle probe and it has never been utilized. So hopefully when we get another contract of truck frames the probe can be used to make life a weeeeee bit easier. The other problem is, no one is experienced enough to program the probe. The shop programmer has no idea. What software would be used in conjunction with MasterCam. I think work would benefit from bringing in an outside person skilled in the area of programming the probe to do all the checks needed to make sure the truck frame doesn't fail inspections after it's removed from the machine.

@Colin Gilchrist Ok So i changed the Z.25 To Z-.015 It ran without an alarm So i probed all 4 corners individually to see what is what P1 = -17.4552 P2 = -17.4767 P3 = -17.4825 P4 = -17.4657 After running the G65 P9820 The G54 Z populated with -17.4676 I'm stoked that I'm getting closer Biggest Z is P3 So i need that + .015 Ah.... a doh moment I need to change the minus 15 thou to a plus 15 thou And boom I get the right # Wish I could come spend some time with you guys to really get this macro stuff figured out. My only other ? Is Do I need to add the U and if so what value And I'm not a 100% sure what U is doing Mike

This is actually what i ran this morning It gave me a 1092 probe open alarm What I want to accomplish is Measure the 4 corners Take the longest measurement (which will be my lowest corner) Say Z -22.115 ( biggest Z / lowest corner) Have my new Z offset be Z-22.130 So add 15 thou to longest Z Hope that makes sense Mike

So when i ran the code i ended up getting a 1092 open probe alarm as soon as it reads G65 P9820 line I tried to upload a pic but it errors out File is small enough I can email the pics if anyone has time to look Thanks Mike

Morning Not condescending at all

@Colin Gilchrist @crazy^millman 2013 Haas VF4 with probing and tool setter So finally got the batteries needed for Probe and Tool Setter. I got it all setup and working. Today the weldment job showed up so I played around with the probing of the Z surface. I had it probe the 4 corners in Z and input each corner to a Z work offset ( G55 thru G58 ) Then i picked my biggest Z # for my G54 work offset. ( This part done by me manually inputting the new Z #) So I went thru this post and came up with this code to try tomorrow. ( also went thru the Inspection Plus on P9820 ) G20 G40 G80 G17 G103 P1 (Block Look Ahead) T25 M6 ( Probe ) G90 G0 G54 X.5 Y-.5 G43 z2.0 H25 G65 P9832 (Probe on) G65 P9810 X.5 Y-.5 Z.25 F100. (Protected Move to P1) G65 P9820 Z.25 I6. J-.5 I6. J-.5 I.5 J-5. S1 (P2 TO P4) G65 P9833 (Probe off) G0 G90 Z2.0 G91 G28 Z0 G103 ( Activate Look Ahead ) M30 On the p9820 line I'm not sure what my Z should be.....the Z.25 will locate the probe .25 above the previous Z0 Am I in the ball park with this. Just so we are on the same page. After probing the 4 locations in Z, I want the biggest Z # to become my G54 Z work offset #. Thanks for any input Mike

Hey Colin, I didn't take it that way...all good. Thought I should supply some info on me. I will do my best to go thru the inspection plus book. The Haas youtube channel is such a great service to us looking for answers via video. Always checking that page out.

Morning I'm totally familiar with g-code and can program We are a union shop... Machinists in one programmer in the other one...( No one wants this tech to be used for the better. It's been sitting in the drawer for a year +. I'm very intrigued and interested in learning this. I do have the inspection plus pdf printed off. I'm very comfortable on our Haas . I'm sure there is stuff still to learn but i'll deal with that when needed Also been machining 25 yrs and i mess around doing side jobs with Fusion 360. So I have a good understanding Obviously not as good as you all...;)

Yes I'm just going thru his links... To tell you the truth I'm even more confused ... LOL Also at work we have a designated programmer and he uses MC . No idea if his software has anything for custom probing cycles. What I'm doing at work is kind of all on my own with no support. We have a 2013 Haas VF4 with probe and setter. No one ever uses it and I've been the soul person running it for almost a year now. I think once I can get some of this figured and understand it, I may be able to find lots of places to use the probe other than work offsets.

I started to write that out today and when I went to try it, batteries dead in the probe...:( Now I need to wait till batteries come in. Could you share this information...

I guess I should of left more information Part is a weldment . The top surface needs to be faced. Just enough so it's a clean machined surface. I'd like to figure out how to do it with the probe. ( This macro stuff is completely new to me. ) Been messing around with #5221=-41.8508 (G54 X) as an example and have that all sorted out. So my X...Y...Z offsets are now populated via the macro. So with this weldment I would like to probe the top surface (Z) in all 4 corners . Then have the lowest corner become my desired Z offset #. Hopefully that makes more sense. Thanks Mike

Great information here. Can anyone shed a direction to figure out how to probe 4 corners and have the lowest corner inputted into my desired Z work offset' Thanks Mike
