    Not a problem thanks.

    I tried removing the screws. Red light on solid.

    Test 1) power up robo 3d, red light comes on stays on.
    Test 2) don't power up robo3d, plug USB into computer, red light comes on stays on.

    When I get back tonight I will grab one of my RC BEC's and plug just 5v and ground in and see what happens.

    Thanks

    @KTMDirtFace

    Ok can you please check the wiring (referencing your pics from post #337)...looking at the IR sensor (from left to right) is OUT, GND, VCC. You have white, black, red. Ok fine. Looking at the ramps you have +, -, S as white, black, red. I think the + and S need to be switched.

    I think your totally right, must be getting full 5V going into signal for me all the time.. Should be + - S on ramps. Thats strange because the X, Y and Z end stop switches were plugged into - and S I just plugged this one in how they were.. but now I see the little indicators at the bottom printed on the board in my picture.

    Will swap soon as I get home, thats got to be the problem.

    At least there was no magic smoke :)

    Well if you had put the ground somewhere else that might have been bad. Switching the + and S does no harm. I sure hope that works for you.

    Awesome! Let us know if you run into any hiccups with the firmware setup. I have mine up and going on the new Marlin 1.1.0 and I have my source for the older firmwares.

    I think I got it.. My Sensor is about 26MM forward of the nozzle and 5 MM to the right of the nozzle

    So I did this. Along with the other changes Jim made in post #125

    Code:
      #define X_PROBE_OFFSET_FROM_EXTRUDER 5 
      #define Y_PROBE_OFFSET_FROM_EXTRUDER -26
      #define Z_PROBE_OFFSET_FROM_EXTRUDER 0
    Ran a G29 and it seemed fine other than it rammed into the end stop on Y. So I need to change these...
    Code:
        // set the rectangle in which to probe
        #define LEFT_PROBE_BED_POSITION 15
        #define RIGHT_PROBE_BED_POSITION 205
        #define BACK_PROBE_BED_POSITION 230
        #define FRONT_PROBE_BED_POSITION 20
    What should I change them to? im not quite sure I understand the coordinate system on my printer LOL.

    No thank you Jim and all no big deal, its all working well now. I wasn't in any hurry. I looked for the R1 wiring dirgram but not very hard. Now that I see the + - on the ramps board it works great. LOL. My bad

    Danzca6, I'm using R1 Lead Screw Upgrade Firmware from http://guide.robo3d.com/Wiki/ROBO_3D_Firmware_Release_Notes?lang=en

    Anyway I think im good, i just monkeyd around with the probe positions. I think its working. gonna button the printer back up and do some test prints.

    Ok buddy. I ran that one and had to do some extra changes to get it to allow me to adjust my z offset correctly. It's been awhile, but I still have my copy of that firmware if you need help.

    Oh yea i haven't messed with z offset yet. Will get to that a bit later tonight, sensor works great by the looks of it now its just tweaking and Printin!

    Thanks for the help.



    EDIT: when i thought it was probing at the Y axis stop, it wasn't it was my fan hitting the binder clips LOL. So I moved those.

    Ok yep having trouble with my Z offsest, watched Jims video and his post on it.

    Not sure whats going on but....

    Jogged controls to middle of bed, Z homed.

    Cannot lower it past the end stop so I unhooked the IR sensor while it was homed.. I actually got 0.9 mm as an offset with a sheet of paper.

    Put -0.9 in my simpify3d start up script.. thought that was crazy becasue thats about what I ran before ( maybe -1.0 or -1.1 )

    Anyhow tried putting giant numbers + 8 even into my startup script.. that works.

    But negative numbers...does nothing it tries to print well above the bed even higher than where my IR sensor actually triggers.

    Start up script, replace -0.9 with something crazy like +8 and that for sure works.

    Code:
    G28 ; home all axes
    G1 Z5 F5000 ; lift Z by 5mm
    M565 Z -0.9 ; set the offset for auto-leveling mechanism
    G29 ; run auto-level
    What did I change in the firmware that prevents it from going negative?

    I'll go back and look for Danzca6's posts

    Yep... That is exactly what kicked me. I would pull up my code but huge storms coming through and I have everything off right now. I posted all the changes I made and why in post #186

    YOU WIN THE INTERNET.. Thank you

    Its working now.

    Possitive offset after your changes work great... I'm not using a lot of Positive but its working.

    Simplify3d Startup.
    Code:
    G28 ; home all axes
    G1 Z5 F5000 ; lift Z by 5mm
    M565 Z 0.4; set the offset for auto-leveling mechanism
    G29 ; run auto-level
    Need to monkey with my Extrusion steps for my Titan and figure out how to stop the OOZENESS during heatup on PETG, but.... its printing now. I'll try a larger test thing here in a bit. Thank you everyone.

    Added My mount to thingiverse

    Mount for Jim's Mini IR - Titan and YogiG's Titan Carriage
    http://www.thingiverse.com/thing:2328579


    =======================================================================
    Its working pretty well, that first test print above was SUPERGLUED to my bed. So I made z offset more and did this test.. bit too high now as it didn't stick everywhere. However its pretty even all around!. but anyway everything is all working.

    [​IMG]

    And another print.. started.. This works FANTASTIC - No longer have to wait for cool nozzle to start a print. ( So I don't melt my lexan surface )

    Thank you Jim, danzca6 and everyone else that helped.

    IR sensor works great. Thanks Jim.

    Note on my Yogi Mount, I put some slop in there so it wouldn't be super tight.. after a couple prints its now SUPER loose. At least I left you the .Step files waldo :) I got it snugged up with hot glue for the moment lol.

    Where can I get one of these? I'm in Canada I can't order off of printed solid. I've been fighting for the last 3 weeks trying to get my printer into a usable state. I'm ready to smash it with a sledgehammer

    Sounds like this will solve my issues with my uneven bed.
