  1. so, I'm glad now, that I was babysitting the printer... suddenly (i assume) there was a Z=0-movement - I've hit the power switch a millisecond before my glass plate was shredded. I've printed this model maybe 50 times (this specific gcode maybe 10 times), with no issues other than the Heater Error (which is why I changed to TinkerGnome's Firmware for the PID-Settings [alternative Fan-Shrouds] ) regarding the ribbon cable placement see this photo I can NOT recommend to seperate these 2 ribbon-cables to fix the issue of unpredictable movements on TinkerGnome's Firmware V16.08.02 Maybe @
  2. I've cut the shrinking tube and the mesh cover (carefully with scissors), seperated the cables so that they are running in parallel (not on top of each other; 'bout 2cm apart from each other) and fixated them on the bottom plate with gaffa. printer is running, so i can not take a photo at the moment. ...and to the bad news unfortunately: I'm in an 17hour print, and 5 minutes ago I had a single random travel to X0 again (print continues, but surface isn't perfect anymore and again I lost trust and I'm babysitting the rest of the print-time) :(
  3. I ran into the same issues when installing tinkergnome's firmware V16.08.2 unexpected and unpredictable moves in X, Y and even small Z-hops. I also had a "Remove Material" triggered randomly while printing a model. So I rearranged the 2 ribbon cables from them mainboard to the SDcardReader and OLED that there is some distance between the cables. Problems solved, printed many hours without any issues!

  6. you can not use the Spiralize-Function (in expert settings/black magic), because Cura is slicing it for a single perimeter und tries to extrude a 5mm thick outer wall with one single line (which is continously moving in z+), so it wants to extrude way too much material and you will get immediate clicks. best shell thickness i get by spiralizing is 0.8mm at a layer height of 0.1mm so mnis' way to go would be to turn off spiralizing and go for 5mm wall thickness (better aim for 4.8 or 5.2 as its a multiple of your nozzle size and your material flow stays at 100%) at 0% infill.
  7. this week i tried to print in old PLA. it was my first batch of generic PLA, about 18 month old. I stored it dark and in airtight plastic bags with silica inside. over this time period its diameter from ~3mm to >3.10mm. it's quite brittle and i have to print a few degrees hotter than "fresh" PLA, around 225-230° sometimes even up to 240° depending on the model and detailing. it tends to carbonize much faster when the flow of material is stuck and when the diameter is going quite over 3mm it gets delicate with the original bowden tube. I use this old PLA mainly for spiralizing vases which
  8. servus Daniel, auch ich tippe auf die Schraubklemme am Mainboard.
  9. Spirit, thanks for your input on this thread, looks like you were able to deal with your issue by applying this workaround. regarding the feet I already printed spacers and levelled the chassis to my table, so that it is at least standing an all of its feet and is not wobbling and moving around, but it had next to no effect to my bed-levelling-issues. your second part of the fix, which involves the spacer is actually the same approach as the washer/nut-combination under my left-rear-side, which made this trouble corner less unusable. but i cannot get my rear-right corner to the right
  10. hello everyone, maybe this picture is worth a thousand words (buildplate is levelled as best i could) @timelapse: my bolts are exactly the same and not lifting the glass plate
  11. a short status update on my side: I made a "workaround" by putting a nut under the heated bed, pressing the heated bed with the glass-plate a little bit up on my lowest corner. you can see this on the second photo of my last post () so i can increase my printable area a little bit. problem is that there is a thermal coupling now via the nuts, so the bed takes a little bit longer to warm up and energy is wasted, and it's no final solution at all. sadly I'm still not able to use the whole building plate. so no large prints for me. I have an open support ticket (#UHK-927-78261) reg
  12. @gr5 thank you for your time to reply the box seemed to be okay, maybe a subtile smell of elephants, but next to no surface scratches. inside the box, everything was in place. first thing i noticed when assembling was that the included filament guide wasn't fitting into its suposed hole, cause the backplate seems too thick. (but that would be very suspicious) my the chassis of my machine is definitely warped, it's sitting on 3 feet as you can see here: http://umforum.ultimaker.com/index.php?/topic/6050-um2-housing/&do=findComment&comment=60758 the initial layer thick
  13. i don't know how I should measure it exactly, the thickness of the glassplate is constant as I my calipers tell me, i also orientated the glass plate 90 degrees and flipped it with the same results.
  14. thanks for your replies, @nallath adjusting on the fly would be kinda hectic because you have to adjust the level back an forth everytime the head moves to one of the "trouble regions" and furthermore there are no relevant levelling screws for the level of these 2 corners @Didier Klein yes, something is way out of plane the glass-plate is flat (definitely) could be the L-shaped part which attaches the buildplate to the Z-rods could be a bent x-axis could be a bent chassis i can only see 3 relevant screws which are accessable without taking the frame apart... I#m awa
  15. I am trying to level my bed. and I'm constantly failing to the point where I lose interest... I ran about 20 levelling cycles with varying every variable which i think has influence the correct levelling (glass plate orientation, heated/cool bed, heated/cool nozzle). the 3 points of the levelling wizard are levelled near to perfection by using 80g/mm²-paper. But no the rest, i have 2 troubling regions, where on one the nozzle is touching the glass and on the other the distance nozzle-glass is too far for the filament to stick I hope you can understand what I mean by looking at thi
