I've been using my haimer 3d on my Tormach for about a year now and I just realize that the needle doesn't start on "0" everytime I use it. Never drop it, but recently broke a probe. Should it start at zero? How do I adjust it? Thanks!

Mine doesn't start on "0" either. It probably doesn't matter though because the important thing is that it ends on "0". If you haven't already, try measuring an edge with the face of the dial pointing toward the front of the machine, then move it away from the edge, rotate the Haimer so it's face points to the right, and find the same edge again. It should give you the same reading. Turn it 90° two more times and make sure it's giving you the same measurement from all four directions.

When you change probe tips you should adjust the Haimer to make sure its tip is concentric with your spindle. The way you adjust it is by putting a dial test indicator against the Haimer probe and adjust the four allen set screws near the top of the Haimer until the DTI doesn't move when you rotate the Haimer in the spindle.

If you figure out that the "0" point is off, you can rotate the dial by just grabbing the bezel and turning it.

+1 Hirudin. Good reply.

Mine isn't at zero either. Like he said the face is attached to the bezel so rotating the bezel adjusts the face. Mine is exactly the same amount off yours is. If I correct it then the haimer over travels. Another easy way to test is to jog into a surface and zero the axis as soon as it touches. Then continue jogging 0.079" if u have the 4mm ball, and see if it is on zero. It should travel exactly 50% of the ball diameter.

The Zero can be adjusted via 4 small grub screws around the outside of the dial, not the eccentricity adjustment on the mount. Haimer provide two hex keys, the larger for the mount, the smaller for Zeroing the dial.

If it does not start at Zero, it is not going to be at the centre of the 4mm ball when you reach zero after two needle turns. The adjustment is quite sensitive

Maybe before you break your first tip... Mine would be wrong if I start at zero... Then again... I may have broken a few tips in the last 5 years...

NICE pile!! I'm seeing a case of top shelf bourbon in that picture (dollar equivalent and lost pain reduction medicine). Between this post and the insert mill trying to morph into a plasma cutter you have truly inspired me

The absolute best way to insure that you WILL break a tip on your Haimer is to not have a spare on hand. I broke a tip on mine about 8 years ago with no spares on hand so I bought 6 more. One to replace the one I broke and 5 more as spares. I haven't broken one since then.

[Steve Seebold]

I have learned it's easy to prevent tip breakage.

1. ALWAYS watch the dial when you're moving the machine. Make sure your machine is moving in the right direction to prevent tip breakage.

2. NEVER make a rapid move when the tip is on the part.

3. NEVER try to set up a part when you're tired.

4. NEVER be talking on the phone when you're using the probe.

Hi Brian. I gather the Probes are not cheap...are you sure the Haimer is as cost effective as a Starrett edge finder etc? I have been thinking of getting a Haimer - because it takes me about 5 minutes to set up XYZ accurately with my Starretf mechanical edge finder - but if I need to keep replacing the probes I am not so sure. I suppose if the Haimer is really a lot quicker it may be worth it, but I have used the mechanical edge finder hundreds of times and it is accurate, and nothing breaks. I admit It is slow and takes quite a lot of concentration though.

"as cost effective"? Yes. I've set up thousands of parts saving 2-3 minutes per set up. Even at $10/hr it's cost effective. mind you those are over the course of 5 years.

If u like your starret stay with it. If time isn't an issue and you like using it no reason to change.

I am more concerned with speed and accuracy and the haimer saves me time and prevents mistakes. Not to mention I set up off bores a lot and that's impossible with an edge finder. The haimer saves me time. Worth every penny.

wow!
Probe tip still holds record for most expensive tool I have broke yet!
I choked on 1 at 60$ and ordered a couple extra in case of another operator error. From my count I see 10 at 60$ , ouch.
I banned phone use in shop after I broke my 1st tip , guessing this is only temporary fix and I will be breaking more from what I see in this picture.

The vast majority of those were broken late at night after working my normal 10 hour day job then machining till midnight and working 7 days a week. My average work week was over 100 hours and I definitely suffered (as did my tools) from the lack of rest.

Damn shuttle wheel just likes braking them I suppose... Or I do. I've broken three on the renishaw on the HAAS since April and those run $100 each. One of those wasn't my fault but the other to were making a fast movement with the wrong axis selected. Woops. Ish happens.

The short probes are only $42 from Tormach and those have worked out pretty well for me. It took about 5 broken tips before I learned what to watch out for while using the Haimer. No. 1 for me is making sure I've selected the right axis before doing a high speed move.

For you folks that have them do yourselves a favor and read the manual and apply the info therein toward setting it up properly. The info therein is a lot more reliable than most of what you read in on-line forums.

Haimer has quite a racket in replacement tips. Bodum has the same racket in the $20 replacement glass for their French press. I use a Starrett edge finder for Y&X axis, a Starrett dial indicator for Z...takes about 60 seconds with no expensive tips to replace. In addition the Starrett dial indicator tool is used with an elephant foot to quickly find Z axis datum with tooling balls and ground rods which takes way less time than a Haimer with a spherical tip.

Wow, this makes me feel better. I haven't been able to live with myself after breaking my 3rd haimer tip.

Thinking about this a little more I am more convinced that you're right and that I was wrong. I now think it should probably point to "0" at both points (the start and the end).

I took my Taster apart yesterday to try to get some coolant out of it. I'm going to try to put it back together and recalibrate it...

The instructions that come with the Haimer suggest turning the dial, not adjusting those screws.

Ie, the screws are another adjustment not mentioned in the Haimer manual. I supposed it could have been that way, but it is not now.

Could you possibly post some pictures of the inside?

Who do u think got little machine shop to start stocking them so I didn't have to wait 4 days for them to get here from Tormach

Thanks for the clarification! I'm glad that I'm not the only one... I'll adjust and test my Haimer per recommendation on Monday.
