    So i build ultimaker 2 clone with third party board (skr 1.4). I'l like to get replay from peopole who own generic ultimaker 2. 

    How machine operates when you press arrow up or down on z axis.

    Does build plate moves up when arrow up press or it's inverted.

     

    I did set it up. so it home to max limit switch at the bottom.  So when i press home it's homing to bottom ( max limit switch) but if i press arrow up my build plate will move down.

    if my arrows controls build plate correctly then when trying to home plate moves other direction.

    Trying to find out is this ok or i need to do more research.

    Thanks in advance.

    @Anthrix Really inspired by your clone build. I'm curious about your MK52 bed plate. Did you create a custom strain relief file for the wiring? Also, was wondering the size of the solid spacers you used?

    Ultimaker With Skr 1.4

    @Porkpie Thanks for the mounting base files. 

     

    I was looking through your GitHub, trying to teach myself and understand all the information you have shared. I admit some of it is going over my head, but I'd really like to tackle this upgrade. I read your post on eevblog about the diodes you added for protecting the MOSFETs. Can you recommend specs for the diodes?

     

    Also, you obviously have serious electronics experience creating those PCBs for the PT100 and PWM fan.  Are there ready-made boards available that would fit the criteria to use on the SKR board? Duet PT100 daughter board?? Just wondering. Thanks!!

    Error Tried printing out of printing area

    in UltiMaker Cura

    I wanted to let you know I think I've solved my issues. Here is what I've done.

    • I have no cover installed over my main board electronics (not sure if this is part of it though).

    • I recently had changed my ribbon cables and secured them away from each other. However they were longer than the original ones.

    • I decided to cut my ribbon cables to the length shown in the Ultimaker Master files. With that change I noticed the issue wasn't as bad. Maybe I was on to something.

    • I have 2 SD card readers, one conveniently on my office desk and another that I have to reach over to plug into my PC. One I purchased from China Aliexpress and the other locally.

    • I decided I'd try shielding my ribbon cables, so I wrapped them with aluminum foil and taped it in place. This led to the printer producing a 100% print.

    • I attempted to repeat this success and loaded another file to my SD card from my Aliexpress SD card reader. The print failed. Upon returning the SD card to the PC, Windows 10 report an error with the card and recommended repairing it. I did that. Reloaded the SD card, again using the Aliexpress SD card reader. Back to the printer and it failed in exactly the same spot the previous print had.

    • Next I formatted the SD card and instead used the locally bought SD card reader. Wrote a file to the card and proceeded to print again. Success! Another 100% print!

    • I have know determined that I have cured multiple issues.

    1. The ribbon cables for some reason needed shielding.

    2. The Aliexpress SD card reader corrupted the Gcode.

    Was this problem really ever solved? I've read through all 3 pages and I'm dealing with the exact same issue. I've tried a new SD card, separating the ribbon cables if there was indeed crosstalk. I'm using TinkerGnome 16.01ex.

    I can't print anything without failure. Pretty desperate to get this solved. Any help?

    UM2 Extended Random X-Y movements

    in UltiMaker 3D printers

    Posted · Edited by Guest

    Hello, I'm hoping someone might help me with a clone I built?? Please?

    The issue I'm having is randomly during a print the printhead will travel out to either the X or Y limit, then go back and return printing as if nothing happened.

    You can see in the attached photo the few times it did this. I also experienced a Y-axis shift but I'm confident I can track that down.

    I just finished building it. It has the 2.1.4 mainboard from Aliexpress. I'm running TinkerGnome 16.01. Not sure exactly what else I can add to help. Thanks in advance!

    UM2 stepper motors?

    in UltiMaker 3D printers

    Posted

    Hello, I'm new to the 3d printing world. I like tinkering around with stuff. Currently, I'm trying to learn all I can about how these printers work.

    My question is what stepper motors are used in the UM2, for the X, Y, Z axis and feed? The reason I ask is there seem to endless different motor specs out there and the UM2 seems to spec out as printing quite precise, so I'm just curious. Thanks in advance!
