Tonight while doing a probe calibration the machine did what looked like a z rapid into the ots touch plate snapped it off and just stopped in its tracks.
Not sure what the fuck happened but I checked and double checked and my inputs are correct. Also this isn’t my first or 5th time. I’m been doing it a lot here Latimer bc of accuracy issues I’m having and it’s all over the place. Some days it’s good some days it’s not. 3 years and has never ran right. I believe I got a lemon. Oh well fuck me.
Has anyone seen anything like this?
Now a couple months back I had issues when I tried to calibrate and couldn’t get the tool probe to come down and touch off. Didn’t want to touch it but now it blows right on through breaking shit. Sorry for the cussing I’m just pissed. Everything I had went into this and haas hasn’t lived up to their end. Maybe I just got a lemon but they never bent over backwards or forwards for that matter to fix the problem.
 
I’ve heard of issues with the laser tool probe having a bug that can cause it to crash.

Haas and renishaw went back and forth on whose side the error was on. I believe it was haas.

I had some weird stuff happen with calibrating and what ended up fixing it is Haas sent me the calibration and pickup macros and I re-loaded them and it fixed my problem. Not sure if this could apply to you.
 
something told the machine to move, and it did

during calibration you put the known diameter tool ~.25" above the OTS with manual jogging, if it failed to start communicating with the receiver due to obstruction or low batteries it wouldn't send the move, and any move the calibration macros would send are not rapids. also calibration of the tool probe also involves manual positioning not just sending it from top height till it hits like a standard tool probe after finishing calibration

something else happened idk what to tell you
 
Hey, hey, let's not get carried away, getting all personal and stuff. Why would you need to know something like the year, model or which calibration they were doing?
My Ford blew up...its really unfortunate it only had 12000 miles on it but did I mention it was from 1933 and not only did I forget to add oil it was parked in a camp fire
 
It’s a 2020. I talk to terry at champions and he emailed me the macros but I’m not completely sure how to load them into the 9000 folder?
I did this a couple months ago and somehow my warmup program got mixed in with a probe operation. I’m sure I did something wrong and caused part at least. But not sure what it was that I did that caused it.
 
I ran the tool probe calibration about 10” above the ots and when I press start the spindle drops 6” fast. Not quite 100 percent rapids like I thought it did when it broke it but way too fast for any probe or calibration routine. Anyways it dropped 6” fast and then stopped and then started to slowly travel in the opposite direction or Z positive.

I’ve got the new breakaway on and touch pad indicated in perfectly and about to attempt to reload the macros and try again. I bought two extra just in case but for 60 dollars for basically a single machine screw I hope it doesn’t break it. I’ll update y’all for sure.

I meant to say this the last night. A couple months ago I had a problem where when I tried either probing and doing the calibration of the ots with the spindle master setter whatever, I would get the master about a 1/4” above the pad press start and instead of coming down slow it went all the way up quickly and slowly started coming down.very slow. Like, you could count the tenths as the spindle traveled down so very slow. Molasses in winter slow. No matter how long you let it go it would never reach the touch pad. Eventually alarm out with I don’t remember.
I did it the same way I had been doing it for almost 3 years but this time it didnt work.
Well I talked to the HFO and they said to clear the offsets for the tool number that I was using for the master tool setter and that actually worked and it worked up until two nights ago when it but me in the ass.
Something has to be changing in the software to make it do this right?
I don’t see how it can change without some outside help?
Hopefully I explained that were y’all understanding.

3.5558 length
.3112 dia
And it was as close to .25 away as I could get without pulling the miti’s. But it still shouldn’t have dropped that fast especially since it’s suppose 1/4” from the pad.
The trigger speed is way too slow for speed it was traveling. I even checked to make sure I didn’t have the federate jacked up by accident but it was at 100 percent.
 
Is this the process you followed? These steps have to be done in order. From the behavior, it sounds like you ran step two with the master tool still in the spindle. The master tool only gets used for the first step: probing the tool setter. It's supposed to start parked immediately above the presetter, not 6" above it.

In order to reload the macros you need to delete all the 9000s on your machine, then load the file they sent you into and it will "unpack" all the macros back on.

Also I agree with following that video step by step. It almost sounds like you have some crazy number in your tool offsets.

Edit: Actually, while I'm here, I need to replace the anvil on my Haas' OTS. Does anyone have a part number, or is it a standard part for a CMM or something of that sort?
 
See I was told do not delete and when I loaded the macros. The controller asks if you want to over write all, they told me to select yes. That’s what I did. The probing it back up and running but what the hell caused it to drop 6” extremely too fast breaking the well, break-away? No one can answer besides corrupted macros so what the hell caused that shit? It’s not like I’m searching pornhub on the controller and got a virus. Plus it’s acted weird a few times and when speaking with haas they tell me not to do whatever that way but to do it this way. I was doing the way I was told to do it by them when something like this came up a year or so ago.
I have a suspicion that the controller was
updated and that is when the corrupted macros happened but I don’t know a way of proving it.
I guess as long as it doesn’t try to drive a home run through the table I’ll call it a victory. Glass half full kind of thing.
New issues have come up like when you probe a tool its diameter usually falls under the nominal like a .375 will be .370, not now. Every tool is over by a thou sometimes more.
I use to use the cam software in tandem with the probe to fine tune the tool wear/actual diameter but that don’t work anymore either.
It’s all gotta be entered by hand which introduces human error bc I’m not perfect.
And With the 4 tenths it is overcompensating for backlash during y axis direction change, it makes it a pain in the balls to get shit dialed in.
Is there a way i can adjust the backlash comp in the controller?
If yes anyone willing give a how to? Can’t find anything online.
So that’s my update and I’m back up and running somewhat precisely precisionless.
I know that’s not a word.

The first approach of the master tool is kind of fast. It uses the first touch to find the presetter, then backs off and does a slow approach to find it again but, more precisely. The problem here is that it shouldn't be 10" above the presetter when you start. It should be about 1/4" above the presetter button. If you're scared of it crashing again, throttle the rapids down to 5% and dial back the feed rate too.

That sounds like it's running the 'Length Only' macro, for setting a tool length. That's not the same as doing the three calibration steps. Are you sure it was the OTS calibration cycle?

Even if the machine had worn out screws and a ton of backlash, I believe all of that comes out in the calibration. The diameters would all be accurate because of how it controls approach directions and switch trigger distances. Again: this sounds like the calibration isn't being done correctly.

And With the 4 tenths it is overcompensating for backlash during y axis direction change, it makes it a pain in the balls to get shit dialed in.

I just checked my VF-2. Depending on how much stiction you believe is in the Bestest tenths indicator, I'm at maybe three to four tenths as well. I don't have any unusual compensation going on that the calibration doesn't allow for.
 
Macro should always send spindle up a and table to position for tool probe. Then it looks for the skip signal. If your macro is missing a critical piece of code that would get expensive quickly
