  1. Hi all,


    I'm currently upgrading my um2 motherboard to duet 2 WiFi and was wondering if the ultimaker 2 firmware had any limitations due to the CPU e.g. acceleration. 


    I was thinking instead of just replicating the exact setup within the duet firmware,  I could improve the configuration due to a better CPU.  I know I have seen something somewhere onsite talking about the axis can stutter if all are moving at the same time and ??? is set to high.



  2. Hey all,


    My hotend heater blew the other day and since then no matter what I change multiple times temperature sensors or heaters (30w,35w and 40W) with base pid settings for each watt the autotune always fails by over shooting over 20c.  I have tried all suggestions on the forums for pid, but there is a consistent overshoot speed.


    I think my mosfet might be damaged, so I want to build a firmware using heater and temperature device 2 as default. If it is the mosfet at least I can use the 2nd connection as a redundancy so I don't have to buy a new control board. 


    Can anyone advice the source code reverences need to be changed? and would this just be in the Configuration or Configuration_adv as well?



  3. Hi all,


    I'm trying to wire up a replacement nema 17 motor, where voltage amps etc are fine.  its just the wire config is different.


    I have checked the control board schematics, but can't figure out which is -a -b see below







    Can anyone tell me which is which please?  im trying to rewire an e3d with the following motor config








  4. Hey guys,

    I'm trying to understand why a combination of Ultimaker 2  extended and Simplify3d causes out of print area with my custom area settings only on SDCARD, if you could give any pointers it would be appreciated.  I have also noted this only happens in simplify3d, cura etc are fine.

    I have found if I use any G1 command for XY axis in the start script it will cause the error only on SDCARD, removed it works fine in Simplify3d or print from usb

    I do have a custom print area setup due to metal sliders and e3d mount:

    Ultimaker 2 extended custom 1.75 e3d mount and metal sliders

    Firmware: Tinker 17.02.01, others tested

    Print Area: x 0.00-205.00 Y 10.5 - 218.00 Z305.00

    Software: Simplify3d 3.1.1

    Testing start script: " G1 X xx and Y xx  commands fail"

    G21 ;metric values

    G90 ;absolute positioning

    M82 ;set extruder to absolute mode

    M107 ;start with the fan off

    G28 X0 Y0

    G28 Z0

    G1 X15 ; tested x15 50 60

    G1 Z50.0 F500

    G92 E0 ; zero the extruded length

    G1 F150 E25              ;extrude 9mm of feed stock

    G92 E0                  ;zero the extruded length agai

    M201 Z250


  5. Hi Guys,

    I'm finally building an ulimaker 2 extended + after getting the parts over the last 6 months.

    Now its taken 2 days just to get the case right and realise the ultimaker 2 build guide there are differences, dyslexia and bulding a 3d printer dont mix :-(

    is there a knack to hooking sliderblock belts to the oppsite shaft pullys? iv tried but I cant push the shaft towards the other side of the frame and already popped one of the bearings out from the panel.

    are there any videos todo this? i'm a very visual person.

    Best Regards
