Thank you for the link David! Will follow through the thread in the morning.by crussty - Controllers

Doesn’t look like a lot of documentation on the RRF precompiled binaries. Is this based of the Duet or Maestro branch? Specifically, does it support th new 12864 LCD structure that is evolving for the Maestro?by crussty - Controllers

These look very handy. One question: with the smaller board, do you loose usage of all servo pins? Thanks, - crusstyby crussty - For Sale
Re: Mini differential IR height sensor board - 11 years ago
That sounds similar. I think this is either a bug in Repetier or I'm missing something obvious. Watching the logs doing dry runs, I have been able to confirm that when it moves to the center to start print, the head stops dropping when the probe triggers and not at the probe + offset level. But back to the day job for now, this will have to wait until this evening I'm afraid. I will throw a pby crussty - For Sale
Re: Mini differential IR height sensor board - 11 years ago
I agree and think that is what is going on. I have it set now so that Repeater thinks that there is no Z Min so it's defaulting to using the Probe. I'm trying to figure out a way to get it to offset the Z Min height to -1.75. To It's credit, the probe triggers spot on every time... I may end up having to move the probe to Z Max pins and put the Z Min back on but shouldn't have to do that. Nevby crussty - For Sale
Re: Mini differential IR height sensor board - 11 years ago
Hi David, 1 & 2 verified as correct (wiring wise and 2 flashes at least). I am wired into the Z-min end stop and the end stop has been disabled in firmware. My understanding is the probe acts as/replaces the end Stop? 3. Assuming you mean M119? Verified that with M119 the probe shows L when raised and H when at triggered height (1.75mm). 4.

Re: Mini differential IR height sensor board - 11 years ago
Forgive me for asking, and slap me if I'm missing something obvious here... I'm using a Cartesian style printer with Repeater firmware on Ramps. The IR probe is mounted -35mm to the left of the nozzle on the X and inline on the Y. With the nozzle paper height above the glass bed, the bottom of the board is 1mm about the bed (rested it on a 1mm spacer and tightened up the mount). After sendingby crussty - For Sale
Re: Mini differential IR height sensor board - 11 years ago
Thanks for the quick reply! I'll try direct first and see what happens. It's very reflective of at least visible light. If no luck, I'll go for black paper, or maybe even cork gasket material if I can find a large enough piece. - chrisby crussty - For Sale
Re: Mini differential IR height sensor board - 11 years ago
David, Quick question for you: my bed is glass over a very reflective phenolic base. It creates a virtual mirror surface. For the probe to work, I understand I will need to reduce this reflection. I'm looking into finding a material I can sandwich between the two pieces and wondering if the board triggers better/more accurately on specific colors? Example, lets just say I was going to put a pby crussty - For Sale

Thanks David, anxiously waiting. I have been wanting an IR solution that works with glass for a long time!by crussty - For Sale
