Z height probe macro

[Guest]

I am trying to write a macro to Z height probe.

 

I am going to touch all tools off of the table and I want to use our probe to touch the top of the part, calculate the distance between the table and the top of the part, I set a variable so I can set stock removal amount and set the calculated amount into the correct work offset based on the W callout in the G65 line.

 

Before I try this out can any of you macro guys tell me if this will work.

 

code:

---

%

(G65 P8300 C2. R.1 W1. Z-.25)

(C = RETRACT HEIGHT)

(R = AMOUNT OF STOCK REMOVAL)

(W = WORK OFFSET NUMBER)

(Z = PROBE HEIGHT)

O8300(Z AXIS POSITION)

(CHECK)

IF[#23GT6]GOTO2

#3004=2

G90G31Z#26F40.

G0G91Z#503

G4P200

G90G31Z#26F.5

G4P100

#100=#5063

#101=#5203

#102=ABS[#101-#100]

#103=#102-#18

G91G0Z#503

G90G1Z#3F60.

#3004=0

N1IF[#23EQ0]GOTO3

#122=5203+[#23*20]

#[#122]=#103

GOTO99

N2#3000=190(WORK SHIFT OFFSET INVALID)

N3#3000=193(WORK OFFSET OUT OF RANGE)

N99M99

Should the original work offset be set to zero before this runs? What workoffset is active when you run this? You might want to make a check to be sure it is before it runs.

Do a search john, I know I had posted sumfin about this about a year ago.

If I ca dig out the V9 post its yours, just gimme a couple days.

Thnaks Hardmill,

 

I'll do a little more hunting in the mean time.

 

Thanks tryon also, I think you are correct about zeroing first

I have not had any luck digging this up Hardmill.

Make sure you put the machine explicitly in G01 Feed mode when using a skip signal with a feedrate.

 

The G0G91 will cause a problem if you don't.
