    Upgrading from UM1 to UM2 , worth it?

    in UltiMaker 3D printers

    Posted

    Hi,

    I run a small online printing firm, and use 4 UM1, printing in PLA.

    Fully upgraded, latest drive, V2 head, and all have heated beds.

    These have proved very reliable, and I enjoy the quick loading, print speed, and quality.

    I wish to "speed" things up, and improve quality. as I constantly have a Queue of jobs.

    -----------------------------------------------------

    Is the UM2 worth the upgrade?

    Will it print faster? better?

    I normally print at 0.15mm layer height at 70mm/s , 40 perimeters, 200 travel

    How easy is it to load?

    Slicing with simplify 3D.

    I welcome your comments.

    Cheers

    Dave

     

    enable output pin when print finished and get an email.

    I want to enable an output pin, when print has finished.. I have tried to use the second heater o/p. but cant get this to work.

    M42 P4 S255;

    G4 P5;

    M42 P4 S0;

    Do i need to do something in the firmware for this to work? I heater 2 enabled by default?

    If i want to use another available pin, do I need to "define"it, if so where.

    -----------------------------

    Basically once I can get an o/p to do something when finished,, I'm going to link it to an arduino with ethernet sheild... using this I can get an email, when print has finished using "pushing box"... I'm using 10 printers, and this would be an awesome feature.

    ----------------------------

    I would really appreciate some help with this,

    David

     

    Hotend upgrade V1 to V2

    in UltiMaker 3D printers

    Posted

    I'm running a 2 Ultimaker original

    One has a V1 hot end the other V2

    I want to upgrade the V1 hot end as I can definitely see the difference in performance, and I keep getting the odd blockage in the V1.

    I don't understand why I cant just change the block tube and nozzle? I find it frustrating that Ultimaker sell a very expensive kit with wood and everything else.

    PLEASE could someone explain why and what I need t0 change to get it to perform as the & be a V2 hot end?

    It looks like the wood is I have on the block is updated with the curve designs.

    Can I just fit https://www.ultimaker.com/products/nozzle & https://www.ultimaker.com/products/isolator-tube

    In theory this should improve my retraction, ooze?

    Thanks

    David (still learning)

    Fantastic response, you really go out of you way to be helpful :wink:

     

    Both machines have the latest firmware via http://marlinbuilder.robotfuzz.com/

    I assume this is okay and has the bug fix.

     

    I still get blobs which happens when the head lands on the next bit to print, or slightly before it.

     

    I'm using faberdashery white at 230 c and tried lowering it to 220 slight improvement.

     

    Ive pulled FW to 35 speed and set cura to 4.5mm at 35mm

     

    both machines are now using the v3 bolt, and one has the v2 hot end.

     

    I've looked at your z settings, and will see what this will do. but the main prob is the ooze between places.

    edit: gr fixed link above and restored lost sentence

    Thanks for the reply..

    Printers 2x ultimaker original.

    I've been messing about with retraction speed. and most people talk of 30-40mm/s

    It sees that my Firmware has a limit of 25, which I can adjust with the ulticontroller.

    so if I set Cura to 40, and it is set to 25 in firmware, is 25 the max it can go?

    also would be REALLY keen to see what you guys have in your set up for xy speed, acceleration etc..

    thanks in advance

    Ulticontroller and other Speed settings

    As GR5 suggested in another post, I want to set my speed to 100mm/s and then use the % of the ulticontroller to adjust the speed, hence 50% = 50mm/s etc.

    Q. Does this effect the retract speed? and travel speed?

    ---------------------------------------------------------

    I understand that really I should try to keep infill and perimeters the same speed, to reduce lag,

    Q. but what would be a comfortable and safe difference outside 80% of infill speed?

    --------------------------------------------------------------

    Im using Simplfy3d and all settings are mm/min, so I assume its just a simple matter of divide by 60 to get mm/sec?

    i.e 6000mm/min = 100mm/sec?

    thanks
