Nice find! I've been looking for an affordable Office Mill in my area for a long time. Good luck and looking forward to seeing you get back to the Morgan press.
good video. I especially like that you pushed Z+ to get a small gap below the tool before doing anything else. It's a habit that I'm CONSTANTLY trying to drive people into adopting. I also really like that you showed a verification code which is another thing that is invaluable. I usually go with a final value of Z3.0 since it gives a big stopping distance that can be easily measured with a handy 1-2-3 block. Myself I just leave the TLO values set to whatever was used to qualify them (like your tool setter) then measure the relative distance up/down to the work origin using the last tool that happens to be in there. It's not quite as "universal" as setting things to the table then shifting them up to the workpiece, but after a couple more months/years you may say ehhh too much typing :)
Thanks, I appreciate it. I picked up the Z+ trick in one of the many videos I watched trying to understand all of this. The test code also took some research, and a fair amount of trial and error before it all clicked and made sense.
Thank you for pointing out the native units are .0001in. Keep in mind that if you do a "Dwell" (G04 Pxxx), the default unit is in MILLISECONDS, and you must likewise use a trailing decimal to indicate that you want integer seconds. [G04 P10] is 10 milliseconds. [G04 P10.] is 10 seconds
i guess im asking the wrong place but does anyone know of a way to get back into an instagram account?? I somehow lost my account password. I love any help you can offer me!
@Grady Santiago thanks for your reply. I got to the site through google and Im waiting for the hacking stuff atm. Looks like it's gonna take a while so I will get back to you later with my results.
Next tool will work even after you raise z jog as long as you dont select anything else. On tool changes I always type tool number and atc. You can ch setting to change tool shortest direction. To do the z shift , I origin the z operator position at last tool length measured. Then move same tool to top of part and put that number
When setting the height offset I press "z" then "origin" when the setter is on the table surface and this sets the operator number to zero. It's the number nearest to my hand and closest to me. So then when I touch on the top of the job I'm not looking at the number furthest from me.
Are the values in Geometry equal the distance from Z zero machine coordinate? I've seen a different method to set offsets. When the tool touches the surface of the part, for example tool number 1 you place the cursor into the Z position of Work Offset Table then you press PART ZERO SET button, then you go to the tool length table and move the cursor into the first tool of the Geometry column, then press 0, press F1. Would this method work?
I'm using this approach because I don't have to touch off on each part. All the offsets in the tool table are relative to the machine bed. And I have a few known Z offsets (relative to the bed) for G54, etc. that are based on locations in the vise (with different parallels). That way I can make sure I have the right offset in G54, use the bottom of the part, and off I go. No need to touch off end mills again. Hope that makes sense.
I didn't. The measurements are relative. So I'm measuring the distance between the table and the "zero" point. That difference is what I enter into the controller. Likewise, the offsets for the tools are also relative to the table.
Lack of dogs is pretty common for smaller, lower power spindles. This is ISO-20 with a 5hp motor. The dogs are required to deliver more force into the end mill. But the Haas OM-2A is a precision machine, and not meant for heavy cuts.
JohnSL I had the same problem.. started with Mach 3 and then path pilot. Haas wants to see every tool touched off of the z zero for some reason. Doesn’t make sense with probing approach.
There is a way. Set a master tool to zero and have all other tools set from that. Just like you would on a Heidenhain machine! So when you touch on with your master tool (say it's your dial) then all your tools will be set. Or you can set each tool for each job with the tool measure button! Also, your G54 Z offset can be set in the program with a G10 command. As long as you remember that your G54 is the distance from the machine home to the top of your workpiece and that your offsets are the distance from your zero tool. So a longer tool would be plus and a shorter tool will be negative.
The G54 work Z is always relative to HOW you set tools. Z axis always involves tools. You could do top of part with Z axis set to zero. You could do off the table and shift G54z to difference between touch off position and part z. These are both air gap methods. The other way is called gage line. You can use a gage tool to find distance from spindle face to part and measure tools off line. Thats how the Renshaw system works

Soon, very soon. I've assembled the engine hoist--I just need to unpack a few more boxes so I have room to unload the Morgan and put it on the table.
Exactly what I was looking for, thanks!

@Grady Santiago It did the trick and I actually got access to my account again. I'm so happy:D
Thanks so much you saved my ass!

Oh cool, that's one fewer key press as well. Thanks.
Thank you for the interesting video. I like the Edge Precision tool setter.
Thanks!

I did not understand how you found the height of the 3D tester? if you did it off the video then it's clear, but how?
I didn't. The measurements are relative. So I'm measuring the distance between the table and the "zero" point. That difference is what I enter into the controller. Likewise, the offsets for the tools are also relative to the table.
I dry run in air by shifting z axis with g92 the last offset work table
🔥🔥🔥🔥🔥🔥🔥🔥
Thank you verymuch
You are welcome
I don't think i ever worked on a cnc where the spindle didn't have dogs...looks weird..
Lack of dogs is pretty common for smaller, lower power spindles. This is ISO-20 with a 5hp motor. The dogs are required to deliver more force into the end mill. But the Haas OM-2A is a precision machine, and not meant for heavy cuts.
Tool 1&2 look like 3/8”
why oh why can one not just set the work offset for Z by pressing the part zero set button as is done for X and Y... drives me nuts
I know! I was convinced there must be a way since Mach 3 and PathPilot support that. But, no.
JohnSL I had the same problem.. started with Mach 3 and then path pilot. Haas wants to see every tool touched off of the z zero for some reason. Doesn’t make sense with probing approach.
