Haimer 3D Sensor vs Wiggler (Edge Finder) -

Описание: Comparison of the Haimer 3D Taster Touch Probe and a standard Edge finder. Is the Haimer really worth the money?

In my opinion, for general shop work or for the hobbyist, a wiggler gets you easily within 0.1mm, especially if you don't run around like an idiot like I did in this video! Any more than that or if you're on high volume work, the Haimer will take any uncertainty out of the job.

A further advantage is that for CNC work, the Haimer, when correctly set up, provides a datum for all the tools in your tool table. We typically set the Haimer as Tool 0 and set the datums from that.

It's been said in our workshop that if you can afford a CNC machine, then you can afford to pay a couple of hundred quid for a touch probe. Having used one, I wouldn't go back now.
One thing to check however is that with collet type tooling (rather than Clarke's Autolock tooling) is that the milling cutter hasn't been pushed up into the collet due to insufficient clamping force. If this does happen, then accurate setting of the Z is impossible!
