Thanks Paul, I got it dialed in and this looks basically what I ended up with. Just had to adjust my z depth a bit to get the correct offset from my center location. After reading the manual I found the info about adjusting the overtravel as well so I added that in. Machineguy I'm not sure if I'm using the terms correctly but the code I've quoted above is what's loaded by Renishaw into the Haas. I wanted to add this code to my program to make the probing automated rather than having to probe each part manually. Thanks for the help. Chad

Thanks Paul, but I'm realizing my description of my setup wasn't good enough. The material I'm machining isn't just a square piece of stock. I'm machining a slot in a piece of 1" round tubing. The tubing has several compound bends that make the web macro difficult to use. My x zero isn't actually the center of my material but the center of the slot I'm machining. Sorry for the poor info. I'm also realizing that the single surface probing macro is only the beginning of what I need in the macro. I want to probe a single x surface and have it update my fixture offset, what I didn't think about is that as I touch off that single surface that's not actually my x zero, I want to add a given amount to that measurement to make that point my new x zero for my offset. Essentially, I want to probe a single surface in the x direction and have the macro add a given amount to move my offset a given distance from that probe position every cycle and make that my new G54 x zero.

My x and y zero is the center of my material. Z zero is the top surface.

Please bear with me as I'm new to all this, I've been reading and searching for a while but can't quite find what I'm looking for. I'm brand new to Haas control and probing, and I'm trying to write a short probing cycle to insert at the beginning of my program to locate a single surface. So, I load my part into a set of soft jaws and probe the first part to set my G54 zero a run my first part. My soft jaws will locate each additional part accurately in the y and z direction, but I need to probe the part in the x direction in order to update the new x zero based off that surface. There's a bit of variation in each part so using a stop is not accurate enough. I've read through the provided Inspection Plus Manual, but can't quite get exactly what I need. Using the Inspection Plus Manual this is what I came up with (below), but running the cycle I get an error as it tries to probe the part. T20 M6 (select tool probe) G54 X0 Y0 G43 H20 Z3.5 G65 P9832 G65 P9810 Z1.5 G65 P9811 X-2.9 S1 G65 P9810 Z3.5 G65 P9833 Basically I want to probe a single surface in the x direction and have that measurement update my fixture offset accordingly. Machine is a 2015 Haas VF2 Thanks in advance for the help, Chad

SCC1, you were right I did miss a step, in the final process using the updatepost.dll I was still selecting the X2 version of my post. Once I selected the newly updated X4 version all is well. I figured it was something simple, just sometimes I need a little help. Thanks again. Chad

I'm sort of new to the site and Mastercam so please bear with me. We just upgraded from X2 to X4 and when I updated the post and ran a toolpath through the post processor it's not coming out in the proper format. I tried running the program on our Mitek that uses a Vickers/Acramtic controller and get an error when it tries to cut an arc or circle. The Code that Mastercam used is not one our machine recoginizes. Upon looking back at older programs the G code that is output for an arc is totally different than what I am getting now. EX: G2 X-8.075 P.075 F30. = Doesn't Work G2 X-8. Y.7266 P.0234 F25. =Works/X2 format The post was a generic one that was modified some time ago for I think version 7 and updated and ran with versions 9, X, and X2 successfully. This was all before my time and I'm a bit green when it comes to this stuff. Thanks in advance, Chad
