Maybe place the probe in one of the lowest slots to reduce the fall height if it drops in the future? And perhaps you could add some cushioning at the bottom of the tool changer.
looking at it in the future its would probably be easier to do the gantry alignment to by loosening the coupling on the shaft that couples the top and bottom rails and rotating the side that needs to be adjusted by hand then tighten the coupler once its in the correct position.
My understanding of probe designs, is that they use ground balls, in a triangle configuration inside the probe, as it touches, these will either disconnect from one ball/side at a time or in the case of vertical z axis probing, should be all three at the same time. The advantage is that it will take alot of force to damage one of these hardened and ground balls inside the probe. Since you always have too recalibrate when replacing probe ends its likely to be in a range of what the calibration takes care of. But I guess if it was me I would probably setup a probe and repeat macro so i could see if its still operating within its accepted repeatability range for the probe.
I just don't understand why people try and fix their machines themselves. The time and labour required + the cost of things going wrong is such a false economy compared to getting an engineer out. I know that engineers aren't cheap (about £800/day here in the UK), but they get the job done quickly, so you're back up and running, and they take the blame if stuff like this happens....
I don't necessarily disagree but I think it could be that the mindset of the engineer who wants to make this career, also likes fixing things themselves. In software engineering, lots of people spent days and days customizing their personal editor, keyboard etc, knowing that it's often nowhere near 'worth' the efficiency (ignoring ergonomics -> less injury), but because it taps into why they made the career choice, and in the hope it might help their knowledge later
Here in Italy we have, for example, very few technicians at Mazak (I run Mazaks), the guy told me they went from 5000 to over 11000 machines operating in the country, while techicians stayed mostly the same, and, more of that, a bunch of them advanced in career and now work only from the Office and not on site, while not hiring enough guys Who would do on site jobs. Therefore, sometimes it takes a week or so, before you can have the right guy in the shop, so you totally need to be able to fix some more common problems yourself. It also allows you to better know your machine, and sometimes you might be better at knowing some stuff, like sensors location, wiring than the average Mazak guy who has to service dozens of different models and simply cannot remember everything.
Sometimes taking a look fixes a thing in 1h, when asking someone to come by would be days. Sometimes it ends up taking a bit, yes. Personally i cant resist
A few years ago I was hired to run an older large horizontal Mazak mill. Found out the tool carousel was losing track of its position. First thing I did was take out the probe and then every other tool that was mounted. That was an old machine that was hard to get any parts for. Best practice for JohnGrismo would be to get or make a 3d printed dummy tool to do testing with.
the are both Drives there is no slave. Please make sure the pulley is not slipping and also you should align both linear carriage to a known position before setting the coupling
I hate the magazine. It broke once on an Okuma horizontal milling machine (1 belt) and the rotating mechanism ran all the way to the end of the belt. Into the cover. BT50 150+ Magazin
It's incredible such an expensive machine has issues like this... T-slots frames for such a critical part; cheap 3d printer parts in a half a million or more machine.
On this week's episode of "the kern is being an asshole"😅😅😅😅 maybe a great idea maybe a really bad idea, but what about changing the belt and pulley to a chain amd sprocket? Just a thought
Testing with the most expensive object in the tool changer for absolutely no reason 😂
Mount the probe on the speedio , calibrate and run a few measure cycles in the ring for repeatability check.

When you're in prison never drop the soap.
When you're in the machine shop never drop the probe.
In both situations you are screwed.
That gave me a chuckle.

He talked about it on the podcast, Kern did not have the assembly in stock in Amerika i think

My heart dropped as soon as I saw the notification 😭
Same here !😯
"Boss, we could easily make this machine stop dropping probes."
"Nope, we make a lot of money selling new probes."
They make plenty from operators crunching probes, no need to make the machine join in too.
On my homebrew wood cnc machine, I have a few layers of foam insulation under the tool rack "just in case"

It has come to it. The probe dropped. Ouch.

Why didn't you just changed the lower belt a few teeth on the lower axle?
Who's chip is this? Kinda like a girlfriend asking Who's hair is this. Lol
