I’d love to get the z probe from Carbide but it’s been a few weeks since Copper was released and there’s no update on when it’s going to be available or whether it’s even actively being worked on.
Has anyone tried the Z probe offered over at Inventables? It goes for $30.
Carbide has pictures up on their Instagram that show what I think may be either a final test run or the first production run of their probe offering.
I tracked down the one Carbide is apparently working on, it probes not only Z but X and Y as well. Looks pretty amazing.
Are the new touch probe connections to the Carbide Motion controller made via the existing “probe” inputs? Conventionally touch plates have been a simple 2-wire connection, but I’m wondering how this active probe design sources power? I’m putting a wrap on my new dual CM controller project and would like to know.
Also, if you know the rationale for an active/amplified touch probe over the existing logic-level convention would you mind illuminating me with that information too please?
Thanks in advance…
There was a comment about that a while back in this forum. IIRC it was related to increased sensitivity (?)
This model is a has a 3-pin connector. The connection will depend on the version of your GRBL board. On the 2.4 ver, there is a small 3-pin connector called “reserved,” and it simply plugs in there. If this connector is missing, there is a small pigtail that allows you to connect to the “Probe” (2-wire) connector + a 5V Pin (to add power). There is ALSO a ground alligator clip that is placed under one of the 6mm bolts on the GRBL cover.
I hope this helps.
Thanks @RichCournoyer
Is the non v2.4 pigtail chassis mountable?
I do recall the commentary about the active design being more “sensitive” and would like to learn more. I believe the touch probe input is a direct logic-level input pin to the mCU and I’m wondering what the active design improves over this convention (i.e. what is the inherent marginal connectivity/operational problem that the active design is trying to overcome?)
You already scratch it, gosh!
Looking forward to your report.
Jim,
Way to much information to ask at this time. Be patient. I was simply saying it’s soon and not to answer any technical questions.
2). See it work (with some early software: Link
Rich, what are you running for a z-axis there? Doesn’t look stock?
Thanks @RichCournoyer… the pigtail pic is exactly what I wanted to see (not chassis mountable per se). I understand on the TMI aspect too… it’s really a Jorge/Edward/Rob/Apollo Q, and as the saying goes, “inquiring minds want to know”
