Re: [CAD_CAM_EDM_DRO] Re: To tool change, or not tool change

A few years back, I had raised a similar question. I was reflecting on how it
seemed that the various newer PC based control software offerings all offered
Tool Length Comp. and supported tool change G and M Codes.

These offerings would obviously apply for at least someone with tool holders
and Not for individuals who have to chuck tooling in a conventional collet.
Even to date, There is very little available (mechanically) for the "hobby"
and small machine market even though that control software is often targeted
directly to that market.

There are toolholder options from companies who make high frequency spindles
(like Perske), but the cost factor certainly does not reside in the hobby
arena.

It would appear that this would be a very good project for an enterprising
individual to develop and build a spindle that may work with some existing
toolholder, even if it was a belt driven spindle.

I've even thought it would be interesting to replace existing main shafts of
some popular trim and regular size wood routers with a longer shaft that can
be set up to accomodate some kind of holder and ditch the collet. I never
took one apart to see if you could "press off" the associated "Motor" parts.
A "Long Spindle" option would sure make a lot of people happy who do 3d work
in soft materials.
