    Parts arrived from Mouser a day early.........

    Hand soldered one board for component fit & testing......try that with a chisel tip iron.........

    Began program/test fixture today, printed base on 0.3...a little rough but Pogo spring fit snugly & holes align well. Base will have two other layers..........out of town Friday.........fixture & maybe stencil'ling this weekend...............

    I have been a bit busy with other projects lately. I also built the differential ir sensor probe but I couldn't get it working quite right.
    In the meantime my pibot sensor arrived so I thought i just give it a quick test so we can compare precision to other contactless sensors. Could one of you do this probe repeatability test with your differential ir sensor?
    to do the test sent this gcode to the printer: M48 n10 V4.

    I tried two:
    the pibot sensor: http://www.pibot.com/pibot-optical-reflection-endstop-rev143.html ($5)
    I get this:
    20:14:52.927 : M48 Z-Probe Repeatability test
    20:14:54.521 : Positioning the probe...

    20:16:05.343 : Standard Deviation: 0.035861
    I haven't printed with this machine yet so i do not know if this is precise enough

    Inductive Proximity Sensor,LJ8A3-2-Z/BX ,NPN,3-wire NO 8mm (about $2,20), needs a metal to detect so i have a glass printbed with 3 layers of tape on it: bottom aluminum tape,then kaptontape, top painterstape.
    I get this:

    This works good, also for big prints with auto levelling i get nice attachment anywhere on the bed.

    you can find results for other probes in this thread: http://3dprintboard.com/showthread.php?2802-Auto_Bed_Leveling-Z-Probe-Repeatability-code

    Printed Program/Test Fixture for Mini-IR Height Sensor, successfully flashed first assembly.........Next install in Robo.......Note: hand-wired version still installed in Robo and has been functioning well...........excuse the bad print quality....old black PLA setting out for months............accuracy of print was excellent...Pogo pins in Bed of Nails fixture, aligned right-on with .025" round vias......was able to view thru fixture with top bracket removed & pressing down on a not populated PCB............

    Because the sensor sits on the side of the head I have to callibrate the z-offset everytime something changes on one of the z axis, not sure how often that happens.
    That is why I want to split the unit or go smd so that the sensor is small enough to fit in front under the fan.
    Otherwise pretty good results.

    Received some physically smaller IR LED Emitters today, ordered Thursday, arrived today Monday.......Here's the part number........
    First group work fine but are close to 4mm wide.....these are about 2mm......first group a little tight in PCB......sidebar......Dave recommends the 'pink' ones..........I have accounts with Digi-key, Mouser, Newark & Allied........Digi-key & Mouser have the pink ones 'obsolete'..........Newark & Allied are back ordered......The pink ones have a 40 degree viewing............that angle number is large, and the chatter I hear is a lesser angle may be their new production runs.....the new smaller ones I just received have even a lesser angle ~18 degrees.

    The pink ones were chosen to help in side scatter & ambient IR..........the pink epoxy helps to filter the near IR Light from the encapsulated die...so far I have not noticed problems....I'll test further...........

    Mfr. #: SFH 4141
    Desc.: Infrared EmittersInfrared 950nm

    50 $0.238 $11.90
    50 Shipped Oct 30, 2015


    I have had conversations with Puff & Mowi about their M48 tests..........I have spent about two days struggling with that Marlin 'compatible' command.....Now I know why they call it a M Command, its been that....more about that tomorrow & much else...Take Care Robodudes

    I'm not sure the repeatability test is in/on for our particular flavor of firmware

    Actually, I think M48 is in all flavors of Marlin since 1.0.0 so unless Robo actually did some software modification other than just manipulating configuration.h, then it is there. Hint: We know they didn't 'program' anything different.

    #if ENABLED(AUTO_BED_LEVELING_FEATURE) && ENABLED(Z_MIN_PROBE_REPEATABILITY_TEST)


    Man, I've tried this code & another similar code that stated 'functions with Marlin'....Placed in a few places...could not get to compile...........worked with this for two days......no luck, but I'm not a code-i-phyle person......In most Marlin firmware, the following statements show there-self in Sub-heading: Marlin_main.cpp, not so much in config. h................I was thinking about just running auto level 10x & pluggin' values in the the standard deviation formula with all the averages, sq roots etc. then I threw some cold water on my face and said screw-it.............so for now...........I have set the bench up with the stencil & surface mount oven & will begin building right after lunch.............hang in there robodudes.....we will get this..........

    I could be wrong, as I haven't used or looked at Robo's "version" of the firmware in several months.

    Update: I just searched through the Robo firmwares, including the newest for the lead screws and the +PLUS, M48 was not implemented. It is, however, in the 1.1.0 RC2 that Is posted elsewhere in this forum.

    Thanks Here'sssssss Waldo............

    I figured you would be the one that would dig into the code...........I searched & compared versions & located a few firmware's, marlin compatible, ripped out the M48 code, tried it here & there, wouldn't compile.....my firmware is already modded in a dozen places to run on my machine....finally tossed the idea.........I am thinking there may be additional code instructions required proceeding the M48 patch.



    "A new version of Marlin was released just two weeks ago. I had a bunch of time on my hands waiting on a print so I went exploring within the new source code. Let me say first, I am not a programmer, so there is some things I don't fully understand, but I can see the bigger picture, usually. First I compared the current Robo Auto-Level firmware with the same 1.0.0 release, to see what Robo had changed. It is too bad that the Robo guys did such a poor job of adding comments to everything they changed, it would have made it easier. After realizing that this was a futile effort that would just have to be done all over again with 1.0.2-1, I gave up on 1.0.0.

    With two Arduino IDE windows open across two monitors, I then spent the next several hours examining each file, line by line to see what Robo had changed in 1.0.0 compared to what was in 1.0.2. I got most of the stuff all worked out and was able to compile the firmware upload it to my Robo and actually print out the Deprime.STL. Over the next few days I'll go back into the code and document what I changed .

    I think there is only one bug, or it could be that 1.0.2 requires resetting the Z offset. I had to dial in about 200 baby steps to get the first layer correct, it seems to ignore the 'M565 Z-1.0' command I have in my start up G code. Good thing I print 4 loops before the actual print.

    With the first print done, it doesn't look too bad, but that one was printed tethered to the computer, I will try the same print direct from the SD card tomorrow. A couple of pictures are in my printer thread".
