    UM 1 en heated bed en firmware probleem

    in Nederlands

    Posted

    Hallo Herman,

    De 'nieuwe' heater connector is zeker niet voor de Heated Bed, de onderste groene (waar je nu het relais op heb zitten) is de juiste.

    Wat ik zie is dat je de thermostaat van de HB in de juiste connector heb zitten (R4), heb je wellicht een ander type hotend vanwege dat je deze in de R21 connector heb zitten i.p.v. de R32?

     

    ColorFabb Copperfill

    You can print with CopperFill with an UMO and UM2.

    The point is that the copper particles are transferring the heat of the nozzle upward the filament just like BronzeFill, only faster.

    When you print too slow (beneath 50mm/s) the heat will crawl faster upwards then the filament throughput, when the filament gets warm at the height of the teflon isolator it will stick to it resulting in a clog.

    To prevent the speed will go beneath 50mm/s, disable the 'minimum layer time (sec)' in Cura by setting the value at 1.

     

    Using new ColorFabb XT Transparent PLA

    Ilsaarin, you say it bubbles which means the nozzle is too hot.

    Lower the temp of the nozzle, I'm able to print with the new XT at 234 degrees as 50mm/s speed on my UMO.

    The old XT even at 212 degrees!

    As a test, heat up the nozzle at 220 and raise heat up slowly every 30 seconds by 2 or 4 degrees at a time, until the XT comes nicely out of the nozzle.

    Then print a simple object (single wall cylinder as example) to test out the best temperature for the material for your nozzle.

    You don't have to stick to the advised temps, I never do.

     

    XT versus PLA/PHA

    And it is also what ColoFabb claims, so good to know it's for real ;)

    I had a chat with them during last month's UltiEvening, and they said they might consider an High temp XT in the future (I would love that as temperature is the only reason I am still using ABS)

     

    Yep, it's real, I also wanted to know if it's true, that's why I tested it.

    To my knowledge ABS has also a GT of 75 degrees or am I mistaken?

    Are you sure on those numbers? I actually thought XT had a higher glass transition temperature.

    I know from Colorfabb it is odor free and it is food-safe.

    It is also suppose to be 50 times stronger then PLA.

    It is also good with bridging. I was shown this impressive 12 cm bridge on an UM2.

     

    GT = 75 degrees, tested it with hot, temp measured, water.

    I've managed to achieve a bridge of 14cm with a UMO, it could be larger if you take the time for it to tweak settings.

    And about the material itself, it is indeed PET, specs can be found here:
