    Hi,

    i need some help . I built my second 3d printer using ultimaker controller board.

    My first printer used rods for x and y.

    This printer works on v rails ( sliders that move with wheels on the v rail extrusions ) instead of rods. Everything is working fine, except i noticed that i tried to

    print a test part, it is a square with rounded corners which consists of 4 identicalcircles, and the circles do not print correctly.

    Please see the image attached.

    I have searched on the web for possible solutions.

    i have tensioned the belts, i have calibrated the steps for the motors.

    i am using a 30 tooth gear with 2mm gt belt, the steps for x and y are 53.33

    The bed is leveled properly, i use fuller gauges to level properly.

    i don't know what else i can do.

    Can i implement something within the firmware ?

    I am stuck, i really don't know where the problem is.

    what can be the issue i am encountering ?

    I would appreciate your comments, anyone ??

  2. Hi,

    I have built my second 3d printer based on the Ultimaker 2.

    I have edited the Marlin firmware for the Ultimaker2 to correspond to my

    printer ( x,y,z travel limits, directions of stepper motors, and homing to limit switches,etc.

    I have tested with pronterface and everything works well mechanically.

    I did all the connections to the ultimaker 2 controller board, when i swtched power on

    and tried to do a test print, it reset on it's own,and tried again , but same thing happened

    it reset again.

    I thought that maybe it was the power supply which is the same one that ultimaker 2 uses

    so i switched it with my other printer ( which works well ), but still did the reset issue.

    i have changed the controller board thinking that maybe it was defective, did all the connections

    again, but it still resets.

    I am able to heat the nozzle, able to heat the bed, extrude and change material, fans all work with gcode commands ,i was even able to print after a few resets, but it is annoying, and i am trying to pinpoint where the problem might be

    Is there a problem perhaps with the cartridge heater or temp sensors ?

    If so, then why am i able to heat the nozzle or heat bed ? If indeed those were defective

    Can anyone please help me or have any suggestions, i don't know what it might be.

  3. Hi

    I have been doing some tests with my custom 3D printer which is similar to the ULTIMAKER 2 extended

    version. I am using the same controller board and nozzle components plus fans for the hot end.

    I am using a gear reducer estruder. please see attached pictures.

    the FIRST problem i am having is that every time i print , the fans dont't seem to want to start unless i

    nudge them a little, then they work. But that should not be the case

    does any one have any helpful solutions.

    i am using the marlin firmware for ultimaker 2 with some changes accordng to my printer

    travel limits and endstop locations and the motor axis directions.

    aside from that i made no other changes to the firmware.

    The second problem is that the next day when i want to go print something, the plastic does not extrude

    so i have to abort the print, and heatup nozzle through the lcd display and push from the extruder

    until the plastic oozes out of nozzle, then everything is fine again. But this should not be the case.

    i had done the tests for calibrating the esteps and entered that value in the firmware ans uploaded to printer.

    when it prints everything is fine, just that if i close the printer and later on or next day want to print

    before it prints it never purges the material, and have to always push from extruder, heat up nozzle etc etc.

    Don't want to do that,should be automatic.

    what should the spring tension be for 2.85 mm filament , tight or loose ?

    How can i tell what is correct ?

    If anyone can help me , i would appreciate that very much

    ThanksIMG_0789.thumb.JPG.a606e672fb208ac07a7453ee6271674d.JPG[/media]HTB1ek7eNXXXXXc5aXXXq6xXFXXXg.thumb.jpg.f83b8d78e1dd4a5e6a7df6b722f0fbae.jpg

  4. I need some help, i am not electronic savvy.

    The question is i have 2 identical fans ( SUNON, 12 VOLTS ) ( 50mm x 50 mm )

    Each fan has these specifications

    Power current:  105 mA

    Power consumpion: 1.26 watts

    I want the 2 fans to  cool the controller board. I have built a PLA housing for the 2 fans to sit on top of board.

    I am also using the same power supply GS220A24-R7B -- DC VOLTAGE 24V same used on the ULTIMAKER 2.

    I have attached images below. The specs for the power supply is highlighted in green.

    I have already connected the 2 fans in parallel, but when i plug the connector onto the

    board J20  ( fan 19-24 v )  the fans do not want to spin, i feel the motors on the fans

    vibrating but no spinning.

    Can someone please help me, i don't know why they don't want to spin.5a331fec1d5e5_SUNONFAN12V.thumb.JPG.232fa6a348b038104120b22b204021c9.JPG[/media]5a331fec7824d_POWERSPECS.thumb.jpg.cd05e64ee227b1361606314b16402da7.jpg

  5. Hi

    I want to cool my ultimaker 2 controller board. So i designed a housing

    to hold 2 fans 50mm x 50mm. These are SUNON fans

    12v  1.26 amps each. I have connected both fans together, positive wire from one fan

    together with the negative wire from the other. the other 2 wires plus and minus are

    with connector. When i plug the connector to the board marked ( FAN 19-24 V )

    and power it up, the fans dont spin. I see that the fans are trying to spin, but ever so slowly,

    barely nothing but trying. Am i doing something wrong ?? I am not that electronic tech savvy.

    Can someone please help me.

    I have attached a picture.

    Thanks

  6. Hi

    I have made a 3D print to house

    2 fans 50x50 mm to cool the ultimaker 2 controller board

    I have already connected them

    And I plug the 2 pin connector

    On the 19-24v female connector

    On the board , how do I power them up using pronterface ??

    They don't start at all , am I connecting to the proper connector ?? Is there some other way

    Please help , I would appreciate any suggestions

    Thanks

  7. Hi

    I need some help.

    I have an Ultimaker 2 controller board, and i want to test if the stepper motors work

    by using pronterface. I built my own 3D printer similar to Ultimaker.

    I tried plugging the Y motor only on the board, nothing else is plugged in.

    Just want to test it in pronterface if motors work.

    But when i use pronterface, i keep on getting MAX Temp Error,

    click Y axis , nothing moves.

    Is there some modifications that need to done to trick the board into thinking

    that there are no temp sensors or heatbed ??

    I would appreciate if someone can help me out.

    Thanks

  8. As promised here is the ongoing project.

    I am using Aluminum extrusion profiles series, aluminum L brackets, all Stainless steel

    fasteners, many components were custom designed and i outsouced the maching

    all in Aluminum with anodized finishes. Most of the components I ordered are from MISUMI and Mc MasterCarr. For the Z axis i am going with a linear V rail system ( OpenBuilds Type but my gantry plate is custom made),  i have not assembled the glass and alimuinum plate holder yet, waiting for copper grease tube .It is far from finished, but I am eager to see the final results. There will be frosted panels mounted on all the sides, i have outsourced those as well along with some led lighting to give it a nice overall look.

  9. The firmware (not cura) does homing.  Cura just writes out a simple gcode to tell the printer to home.  The printer's firmware is supposed to know which direction to move the axis to hit the homing limit switch and which switch goes with which axis home position and once homing is complete the firmware should know the position of home: (0,0) on an ultimaker.  Something like (-100, -100) on a delta printer typically.

     

    Thanks for the info

    But i am new to all of this, I designed the entire project of my 3D Printer in Solidworks.

    It took me about a month to complete, with whatever free time i had available.

    I will try and post a pic as to how my printer currently looks.

    There are delays in completing it , because the shipping of some components takes forever.

    I will be using the Ultimaker controller board latest version for the hardware.

    But somewhat confused as to how will i proceed when i connect all the cables to the board.

    Can someone guide me step by step ??, i would appreciate that.

    My printer will have somewhat slight differences as to where the centers of the rods and limit switches are compared to the Ultimaker 2 extended plus.

    Do i just start Cura software and hope that all will fall into place.

    I am not sure about that.

    I will also try and post a top view cad drawing showing the dimensions of the rod centers , heatebed, nozzle assemble in all 4 corners ( maximum movement before any interference occurs )

    Maybe this would help in someone trying to help me.

  10. OK, that sounds great, i will definitely try it out when i finally receive my board because

    if i can setup my 3d printer just by using cura that would be more simple. It's just because

    i spent a lot of time searching and came across Marlin, Arduino and pronterface and was geting confused as to what i should use. For example , can i test the board to check that the step motors run and turn accordingly ( just alone without the shaft connected to linear rods ) once i power up the board, and only those motors are connected and the others are not ( i.e fans, heatbed, heater cartridge, sensor ) or do i need to have all connected.

    thanks

  11. I really need some help and advice, so any comments would be greatly appreciated.

    I am currently building my 3D Printer, it will be somewhat similar to ultimaker 2 extended

    but not exactly.

    I would like to know when i finally assemble the frame structure, and then hook up all the wires

    to the controller, what is the next step. I don't know what to do.

    How will i setup the software according to my 3d printer configurations limits, x , y, z travel min max

    extruder, heatbed, fans,etc.

    Usually limit switches are installed where on the x,y, and z axis, is this the 0,0,0 origin ?

    And home position location should be where ?

    i would really appreciate if you can help me out, i am very confused

    as simple as possible, i hope it will be simple.

    Thank You
