    I have been having some issues with the a BigBox V1.1 Hybrid Titan model crashing the bed into the print heads. The previous owner Installed a PEI sheet on the glass bed. It homes great and levels sometimes and others it seems as if the IR sensor does not see the bed and it drives the bed into the nozzle and i have to power it down to fix it. Has anyone had these issues? I am very suspicious that the white grid lines are causing me issues.

    I would like to upgrade the firmware on the unit. Is there a preconfig firmware for the bigbox duel hybrid titan v1.1 ?

    Oh yes... that issue...
    Do you have the thruhole version of the IR sensor?
    Do you IR part look like this?:[​IMG]

    I straiten mine but was not reliable so I upgraded to the SMD version of the same IR sensor:
    https://www.reprap.me/ir-probe-for-duetwifi.html

    Since then mine has been 100% reliable and the repeat-ability is super.
    the Duet board has a script for testing just that and running that gives:

    M98 P0:/macros/ProbeRepeatability
    G32 bed probe heights: 0.054 0.055 0.054 0.054 0.053 0.053 0.054 0.054 0.054 0.054 0.050 0.053 0.053 0.054 0.052 0.051 0.053 0.053 0.052 0.052 0.053 0.052 0.052 0.054 0.051 0.051 0.052 0.052 0.053 0.053 0.053 0.054, mean 0.053, deviation from mean 0.001

    So this as you can see was my solution to the unreliable IR sensor.

    I have the sensor that you shared the photo of. I removed it made sure everything was strait and readjusted it. It works better but it is still wonky it seems like those white grid lines cause most of the issue. If i could find someone with the newer SMD sensors in stock I would replace it .

    You can buy the newer type of sensor from my escher3d.com site, or from duet3d.com, or in the US from Filastruder. However, the newer type will probably still pick up the white grid lines. Can you define the grid probing mesh to avoid them?

    Actually I think I have decided to buy the buldtak flex system if I can just figure out what darn size I need to order.. everything I'm seeing is either to large or small. The newer sensor seems to do better with the buildtak surface if I'm not mistaken?

    Here is the correct size for the flexplate system. I have it and it is tha best thing since sliced bread!

    My experience with BuildTak is that it's just too sticky. The flex system might change that. My experience was applying a piece of BuildTak to the original BB glass bed, then printing. Removing the part made me fear about applying so much pressure for removal that the glass might shatter or break in the my hands.

    I'm curious what the total cost for bed and plate is for the buildtak flex system though. If you can combine the super stick with ease of removal that could be interesting.

    For me the aluminium bed from Clever3D was the overall best single upgrade so far to the BB.

    Do you need a duet board for this to be compatible? Or will i be able to do a straight swap for the old I. R sensor.

    The best thing I've done with regards to the old sensor is move it to the side of the bed. Can't recommend that enough.

    The new sensor is a straight swap for the old one, except that AFAIR the variant that E3D took for the BigBox had a right angle connector whereas the new one uses a straight connector as standard.

    Hey David, got a IR board stop working, 4 red lights on start up no issue but no trigger for IR light when you get close. I can trigger it with an external IR emitter so I guess something on the IR LED side has failed. Have you got any info on some test points to locate the offending part that I could replace save me waiting a week for a new one to arrive in australia.

    You can use a multimeter in diode test mode to check the IR diodes, by measuring between the series resistors adjacent to the diodes and the nearby ground test point. They should show a forward voltage of about 1.5 to 1.6V.

    Just like to report how good the fFlastruder.com support is, contact them about the problem and they sorted me out immediately. Thanks goes to Tim for the great and speedy customer service they have always provided.
