Makes me think I need to check my Haimer just to be sure! Thanks for the info and experience.

Well done! I love backup equipment and machines myself, it's always good to be sure that you can get the job done if you have some malfunctions or something like that. I have a Haimer "look a like", I belive it's Haff&Sneider brand. Does the job. I'll keep watching your videos, for me they are quite good. All the best!!!

That was great! Thank you. I'm looking at the same machines and considering the same purchase decisions that you made. Tormach vs Haas vs Fadal etc. Would you be willing to teach us how you inspected the Fadal before you purchased it? I'm not a machinist. Maybe teach us how you learned to test the machine and operate it in order to test it. Great videos man!

where did you buy the parallel rectangular blocks?

I’ve got the same problem, my 3D Haimer taster drop from spindle twice 😢 due to assembled wrong pull stud, now it shy 0.12 mm ( around 0.005’’) error on X and Y axis with new needle. I saw your link forum and try but it not worked. I’m really appreciate if you help me with your experiment fixed your sensor, thanks

Ever consider drilling and reaming a hole, then indicating and generating an adjustment factor for each approach direction?

I checked mine and found it 0.018 in X and 0.012 in Y!!! Thanks for the insight.

That’s why I make these videos! Thanks for the support! 🤘

I think the answer would be to use a dedicated 3/4" end mill holder and calibrate the Haimer in that holder. Then never remove it from that holder. ER collets are good, but not perfect.

Glad ya found the issue,,,,,I use a wiggler on mine..id be breaking that fancy tool all the time..have you seen the Hallmark Touch Probe?

D J yes, I’ve followed threadexpress as he developed that a few years ago. Looks good!

I wonder if the ER Collet is contributing to the error. Something could have shifted when you crashed. Replacing the tool in the collet could have realigned the Haimer with the Collet Taper to the CAT40 taper. I'm wondering if the calibration only adjusts the XY offset of the ball. The axis of the probe tip shaft might be contributing to the sin error in the x and y axis. Can you measure the probe tip shaft runout in a couple of locations? Also, by using the universal sensor and not the integrated sensor, there is a couple interfaces which could contribute to the error. Be careful about placing the magnets on the C-Thru. Extremely difficult to reposition.

The numbers would be consistent & repeatable - it does not matter if it's out as long as it stay the same amount out very time. the issue here would suggest that depending on the direction the of measure internal vs external there is variation in the numbers. this is one of the reasons Renishaw probes normally use spindle orientation when probing to make sure the same side of the probe is doing the measuring.

how much did it end up costing to get haimer fixed?

I think it ended up being around $250 to repair. Can’t remember if that included shipping or not. If in the US, you only have to worry about shipping it to the US distributor. They’ll ship it to Germany on their dime.

I spent a solid 8 hour day dialing my Haimer in. It is within .0005" all the way around... It makes all the difference. No more assuming or guessing. I would agree that a back up probe is essential if you're running production work. BUT, I still know guys who do everything with a wiggler and feelers. It takes them an extra minute or two on setup, but they don't set up every part and every cycle. They setup and run op 1 for 500 parts, then op 2, etc... I do prototypes, so if I don't have a good probe, it slows me WAY down.

Whoo... I thought at first this was going to be a "How I booger hacked my watzitz and saved a ton of money (don't look at the actual numbers, please don't look at the numbers)" video. This was good; a little confused at first, but then you started making sense. Found the problem, rembered what happened, decided what to do about it. While it wasn't cheap, getting a spare is only smart. I don't even own a business and I have two Interapid .0005 test indicators as well as spare edge finders (with the old school Starret wiggler kit as the final say) as backup, if for no other reason than I've had co-workers crash my stuff. I'd love to claim that I've never crashed an indicator or a Z set tool, but anyone who's been a machinist/CNC machinist as long as I have would call me out on it. Fortunetly, I personally have only crashed one of each.... Most likely because I had bought them new in the first place, and don't want to have to buy them over again. As opposed to people I've worked with who refuse to buy their own and couldn't care less about anything that the company supplied...

Thanks! I really appreciate the feedback and encourage people to look at the numbers and make data driven decisions - heck, even challenge me and my numbers to make sure I’m not just making up “good” numbers for the video 😆... thanks again! 🤘

I sure like my Tschorn!

Why do you think you need that expensive whizz bang contraption to do your work? Machinists have been doing ultra accurate and production work for 200 years without that thing.
