    Heated Bed Problems

    in Third party products & modifications

    Posted

    Hi,

    Are you printing PLA or ABS?

    I also had small warping with PLA, but only minimal. I printed directly on a glass plate.

    For PLA you need a bed temperature of around 50° C. I print first few layers without fan, that it sticks good to the bed, then I had no more warping...

    Be careful when using a fan on a normal glass plate. My glass broke this way, due to the different temperatures on the glass.

    Now I use a special glass, temperature resistant to 800° C and no problems... :)

    For ABS the bed should be around 100° C and you need Kapton that it sticks well to the bed.

    Its just a trial and error thing. Test a few bed temperatures and switch the fan on/off to get a feeling.

    Overall the heated bed added a very big value to my Ultimaker!

    Hi Alx

    Thank you for the reply.

    Well, the only problem for me was that the documentation is not so easy to understand. -At least for me. ;)

    Would be good if the deuligne is included in Erik Zalms Marlin.

    Otherwise IMHO deuligne wont make the race against Ultipanel, because it runs only on an "old" firmware...

    Thanks

    Problems with printing - please help

    in UltiMaker 3D printers

    Hi Michal,

    That does not look good, but my prints at the beginning where looking also like this.

    Its not a good feeling to have such a nice machine beside you, look what nice objects others produce and you can't print. -I know that feeling very well... ;)

    Also I dont think its a temperature problem. You can print PLA at 195 C.

    From the pictures its a bit difficult to say. Are you sure that your first layer sits good on the print bed/tape?

    I had this too, when the first layer is not good you get "modern art" like in your pictures.

    On your picture in the middle:

    Do you have the teflon tape on your brass pipe inside the heater block? -This PLA that comes out above the heater block should not be there.

    For sure this is not your printing problem, but it can cause mistakes in high quality prints.

    Let us know if you find the problem and good luck!

    Regards

    Tristan

    Extruder Motor problems, with Marlin Beta and new Netfabb

    in UltiMaker 3D printers

    Posted

    Hi,

    I have updated my Ultimaker with Marlin from Erik Zalm and downloaded the new Netfabb with 250'000 baud connection.

    In a test print, all goes well at the beginning, but at infill, the extruder motor starts to turn really fast! So fast like i have never seen it.

    The bolt turns itself into the filament and no more is extruded. Also it would be too much filament for the current printing speed.

    Anyone had the same problems?

    Regards
