You'll need to be very up front about what replacements will cost so people feel at ease with the design.

    It doesn't seem completely necessary for the tip to be anything other than carbide.

    Another thing I've always wondered, what about making a probe that's both conductive and mechanical? Have a mode switch on the side so that when dealing with metals you can use conductive for perfect accuracy and for non-conductive materials use the mechanical mode?

    EDIT - I believe I heard in the video your stylus is ceramic?
    Hi Advil - Thanks for your post.

    Re your questions. If you view my other youtube videos on the subject last year - or you may have already? there is information on some of this.

    Just quickly. I may offer a premium model with a Carbide stylus tip and a economy version with a hardened steel ball tip - still very durable.

    A broken stylus would be very unlikely ....but I agree with your point and plan to offer replacement stylus assemblies for a reasonable price.

    In order to keep the price down I plan to only offer the mechanical touch type at this stage.

    Cheers Keen

It looks awesome, I have all the faith in the world that if you've made it, especially from the ground up, it's fantastic!

    Nice Design Work Keen,

    I would think many of us might be interested is this is affordable, as most can't afford the high end probes from Renishaw and others. Nice work

    I was able to remove a lot of the stylus deflection by getting new stylus's from renishaw. the one I have now is a 4mm X 15mm rod and 6mm ruby.

    Hi Gravelleknives.

    What sort of cost was that stylus?

    $60 iirc. The rod is carbide, its plenty stiff enough and a lot more forgiving with minor probing errors.

    Hi Gravelleknives. Sorry to persist on this but was that the price of a new stylus from a Renishaw agent or via another outlet...ebay etc?

    Re: NEW DESIGN CRASH RESISTANT LOW COST TOUCH PROBE

    Looks very interesting. How are you going to cope with shipping where the probe may spend several days in some arbitrary orientation?

    Hi Dave

    The plan is that the Probe will be user serviceable. I plan to link buyers to a non publicly listed technical video explaining applying the fluid and other technical details, and to perhaps supply the Probe with the end cap off, or on loosely...and a tube of the fluid - it only takes a minute to apply the lube and screw the end cap on.

    This will also mean buyers will have viewed and understand the construction and should be more comfortable with any future user service should that ever be required. For example should any contamination from coolant or dirt etc occur, they will still have the fluid and can clean it out and relube. ..or fit a replacement part if a massive crash occurs etc.

    Cheers Keen

    You might be able to vacuum package them which would probably not allow the fluid to move.

    Re: NEW DESIGN CRASH RESISTANT LOW COST TOUCH PROBE

    How about an access cover on the side and just put a few drops of ACF-50 on the contacts every few months?

    Hi Advil.

    That was my earlier design, but now the contacts operate in their own mini reservoirs and the greater bulk of fluid does a much better job of cleaning, lubricating, and stopping oxidisation.

    The end cap can be removed in a minute to access the contacts and apply the initial fluid top up after postage arrival.

    Keen;
    I tried to email you last week but may have missed a response. Is your probe going to be commercially available. I will be interested if one when and if they become available.
    Great work!

    Re: NEW DESIGN CRASH RESISTANT LOW COST TOUCH PROBE

    Put me on the interested list as well.

    Our mill does run under Path Pilot now, but it is a Novakon Pulsar, so does not yet have any point to plug in a probe.
    I will have to research how that is done.
    We currently use one of these. https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1
    It's pretty accurate, but pretty slow as well. It is only as accurate as the operator.
    It does double duty on the Tormach lathe and does a good job there too, but again pretty slow.
    I would love to take advantage of Path Pilot's probe routines.

    Lee, I use pin 15 on the BOB for my probe. Works great on the Pulsar with Path Pilot.
