I recently purchased a 3D Touch Probe from topcom. Great little unit however I’m seeing a little issue when probing the Z axis.
When I run the toolchange macro to initially get the tool height of the probe, I notice the probe “depresses” a little when it makes contact with the toolsetter pin, that is, it moves upward a little as force is applied on contact.
I notice after I probe and change the probe for my first tool, the z is off about 0.25mm. I’m guessing this is from the “depressing” which happens.
I take it I can’t use this probe with the toolsetter?
You are correct in that a 3D Touch Probe and the bitsetter will not work well together without some tweaking. I think most folks that use the touch probes do so with other g-code senders. You would likely end up with macros dedicated to 3D Touch Probe operations.
If you want to get into physical modifications, you could try swapping the bitsetter spring for a lighter one or swap your touch probe spring for a heavier one. I expect neither option is “officially” recommended by either vendor
Good luck on the journey though, the addition of a 3D Touch Probe was well worth the effort when I was using it regularly.
Here is a thread with an awful lot of info on the subject
I actually followed your threads back then, that’s how I got into using the 3D Touch Probe in the first place. I gathered the macros for gSender from those threads and everything has been working fine. I thought you were also using gSender at the time, did you add an offset to remove the amount of “depress”?
Curious then, what toolsetters are the 3D Touch probes actually designed to work with? The probe tip itself isn’t conductive so it would always need to be used with a physical switch like the toolsetter.
