  1. Hello,


    Hope this is this correct place to post, So my UM2+ has been sitting for a month and when I went to level the bed the rear thumb screw is soooo tight I can only move it about 2mm each way so i can not get the bed level and I don't want to break something whats the best why of freeing up the thumb screw so it will move like it use to?

  2. Ran into a weird issue after doing a couple prints using the change filament the homing of the head fails it hits the end stops then goes crazy like it did not hit the end stops.


    worked after powering off and on but does it again after doing alot of prints then trying to change the filament.

    But you can experiment with both settings anyway and check what happens.


    Okay the bed was already set to No PID ("bang-bang"), Played with the power budget total seen no real change. the screen text still jumps even while not printing if you are going through the menu's its very random and happens more often while printing.


    If its not something to worry about and will not harm the printer I'll set the LED and Screen timeouts so i don't see it.

    Do you use the PID mode for the build plate? I heard that this generates a lot more electrical 'noise' than the 'bang-bang' mode and i wonder, if the flickering is related to this?

    If so, can you switch the PID mode off and check, if it makes a difference?


    I'm not sure what mode the bed is on I'll check after this 5 hour print but its stock what ever its set too once flashing and doing the factory reset.

    In addition: during dual prints the power supply is working at it limits, perhaps there's a small voltage drop now and then that can cause the display jittering?

    Another test: try to reduce the value for the 'Total budget' in Preferences -> Power budget and check if it makes a difference.

    What do you mean dual prints? My printer is not running the mark2 mod, I'll check the Total budget thing out.

  5. Flashed Tinker V17.10.1 on my UM2+ and noticed when its doing lots of retractions and fast travel moves the screen starts going a little funny like all the text jumps to the left and back, also noticed the LED lighting flickers for a couple seconds every now and then.


    EDIT: I wounder if this is related to this?



    Is this normal?


    Also can't run the auto pid tune I get failed temps to high.



    I managed to get it to work by turning on the part cooling fan and cupping my hand to direct the air to the hot end for the first cyclical and got very different numbers from stock and using them number over stock lead to the print head not been able to stay on 210c it mostly stayed around the 206c


    Stock: p 10.00 i 2.50 d 100.00  Auto PID: p 8.82 i 0.67 d 29.19


    Is this because I had to direct air flow for 0/5 to 1/5? 

  6. @tinkergnome Would you have any idea's on whats happening here when trying to build on OSX I can't work it out I downloaded the Arduino.app version that is defined in the package.sh file made sure it was in the right location etc.

    Only two things changing are the e-steps to 311 and material load speed to 50 mm/s.  These are the settings required for the bondtech extruder.  Yes, bondtech does provide a firmware but it isn't tinkergnome.  A few people have recommended it, so I wanted to give it a try.


    I was going to compile it for you with the changes for the DDG but @tinkergnome has the material load speed in steps and not mm/s FILAMENT_FAST_STEPS not sure what 50mm/s is in steps



    Also get an interesting error when trying to run the package.sh on Mac

    The initial layer height is always fixed because it's needed for proper bed adhesion. It also stays 1 step size above 0 to prevent empty layers. Since the default layer height here is 0.1 and the max. offset is 0.15 (totalling to 0.25), the initial layer heigh of 0.27 is still a little bit taller, so it appears in the spectrum. But the actual yellow part of the model will be 0.25 (except the first layer ofc). So indeed it's intended.


    Ahh that makes sense, of course not sure how that slipped my mind for some reason my brain was thinking that gauge was only showing the adaptive values not the overall model :/

    Did you notice that "Adaptive layers maximum variation" does not work properly.




    Or is there a reason that it is wanted.


    Just had a quick look and it seems to be grabbing the initial layer height lowering that value then gave me the expected max layer height.


    @ctbeke is this correct behavior?

  10. You could insert the snippet after the first line of skirt/brim gcode that way the head has already moved away from the prime area and has only done a small amount of movement on the bed.


    But that would not work if skirt or brim is off.


    anther way would be to loop over the whole gcode output and change the Z values but that would be really slow to process? for large-ish prints 

  11. I'll give this a test tomorrow,


    One thing does this move happen after the head has moved away from the priming area if not you will want to move the X for UM's or the nozzle with smash the bed clip this is what I use when printing in PETG.

    G1 X40 Z0.05 F4000 ;Z Offset Hack, also move the X to not smash the bed clip
    G92 Z0 ;reset zereo for Z Offset Hack

    nightly builds

    I'm not even sure Ultimaker make the nightly builds public.

    Does the UM team let you know when a new testing build is available

    Pretty sure they will post in here if a new build is made available (well hoping so) 

  13. What's the difference from A1/B1 to A2/B2 I can't see it?



    Because I myself don't have room to run it under the printer I found this to be the only way to get the polybox to work, I wanted it to be beside the printer so I could read the display but it can't be done as it puts to much pressure on the filament turning to the right then going up, even with hanging spool holder inside.
