Welcome to the SeeMeCNC Community

So I got the FSR kit from Ultibot (http://www.ultibots.com/fsr-kit/) and I have them all wired up, and installed and hardware wise they seem to work rather well.

Software on the other hand, is where I can't make heads from tails.

I read MHackney's thread about when he got them to work, but there is no cut and dry solution on what to do if you're using a Rambo board with Repetier software. I don't know what config tool he is talking about. I've chatted with him and he said Duet Board is the way to go, and I'll eventually order one of those but in the mean time I would really like to get this working with the hardware I have now.

Can someone please lend a hand on what I need to change, and where? I've made edits to Arduino code before, so it's not foreign territory but I had something to compare to the changed I was making, right now I have nothing.

Thanks!

I should also note, I Did watch this video here

and it seems easy to follow, but I have no idea if thats the same using FSR's as it is with his switch.

The video is in the link I sent you to the Repetier firmware site last night. It does not matter what type of probe you are using so FSRs look exactly like a simple switch from the firmware's perspective. In fact, that is one of the primary features that little JohnSL board provides, it takes the resistances from the 3 FSRs and sets a trigger threshold (which you can modify with the jumpers) that provides a binary on/off just like a mechanical switch.

okay i watched it twice it seems pretty easy. but i don't know what version firmware i'm on. how can i tell?

the status/log will tell you when it boots up. You can also issue an M115.
