  1. Thanks gr5. The last photo is without glass, sorry me for the photo not very good. The glass seems good. I have problem to hit the right z measure and i dont know why but I see if I change the distance between glass and alluminium the z change. I'm more worried about the difference between the back and the front. whenever I do the manual leveling I need to try a lot of time for hit the correct measure of rear plate. If I do about 14mm in all 3 points I cant complete manual leveling because in to front the bed is crushed to the nozzle. Really thanks for your support.
  2. Thanks @Smithy. I just resolved in this moment. Strange but I redid the manual bed leveling and now print start correctly.
  3. Yesterday evening I turned off the printer after printing without a problem a "cube!" ? Today I launched a print, always for the check my axes, but more bigger (100x100x50). I use active leveling set to automatic. The printer first checked the leveling and then the printing started. Extruded the usual small amount of filament in the left front and then started to make the brim. It makes a strange sound, I hope you can hear in the attached file, and does not extrude. it made only a small portion in the back. I stopped the print, extruded the filament with the manual function, the printcore extruded well and relaunched the print. Same result. Is not my day! ? Thanks. Print sound.zip
  4. I have another problem with my UM3. The build plate to calibrate it correctly, I have to put it higher enough on the back of the two front left-right sides. I also printed um3-buildplate-distance-tool (https://www.youmagine.com/designs/um3-buildplate-distance-tool) and also usign this I need to compensate in rear. It is very cumbersome to do the manual leveling, I have to do it in attempts until I find the right rear position. I encounter this problem from the first day. The glass looks straight as well as the alluminium in the direction of the y-axis. Curved in the x-axis direction. Is this normal? do I have to change some parts? Thanks.
  5. Hello, after factory reset the UM3 start wizard setup, first asked for printcore and all works fine then start removing filament. Stop, I waited for 20 minutes, power off and on the printer, restart wizard, printcore ok, filament... waiting.... I can’t do nothing, only power off .. thanks
  6. @Smithy nice idea, I will try but... I will lost all my settings... ?
  7. Thanks @XYZDesignPro. I would be happy to have your results. I printed other parts more complex with same problem. I think cube can be the easy way to check if printer is good. My settings: 0.25 or 0.4 nozzle (no difference) 0.1 layer Printer speed: outer wall 12mm/s,inner wall 17mm/s, 20% infill, ultimaker pla at 190 with 0.25, 205 with 0.4. I have this difference from the first print I made and I do not think it's ok! ? Thanks
  8. I worked all day trying to solve the problem. All 4 assis had a lot of play and I did 2 times the suggested procedure on the ultimaker website "maintence - check for play on axis". The result is not good, the difference between the two axes x, y remains always about 0.15 mm. It does not seem right to me that a new printer needs to be repaired for the correct operation byf the customer. I just have a china printer for that! ? Thanks @Smithy for your good support. I hope reseller will change my printer with new one.
  9. Thanks @Smithy. I make many measurements at various points including the measure that you suggested to me. Unfortunately, the result does not change. I will check my axis like you suggested me, but... is eally new printer and not cheaper.... I thought I did not have these problems with ultimaker. Thanks for you support.
  10. Hello, I just printed a new cube with cura with this settings: printcore: 0.25 print speed : 30 default all other settings. Filament is Ultimaker pla. Picture axis order is: x,y,z The printer is new and I need to understand if this is normal or my UM3 have some problems. thanks. Giovanni
  11. Hello, first of all I'm sorry for my terrible English. I'm just arrived in the ultimaker world, my um3 have one week and I am excited about the print quality, a little less than other things. The first day I did the calibrations and then printed many cubes of various sizes and other shapes to check the measurements in the 3 axes. I used only Ultimaker filaments (pla, abs) and printcore 0.4 or 0.25., Cura as slicer with default settings. I only lowered the speeds bringing the maximum to 50mm/s and the walls to 20-30mm/s. In all the tests I did, I always have the Y axis a bit more then X axis about 0.1 / 0.16 mm. In this phase I would like to calibrate the various axes with similar tolerances without worrying too much about the exact measurements. The exact measurements I would do later, depending on the materials using the slicer with "horizontal expansion" or by scaling the model. All impossible things to do if you do not have the same tolerances on the 3 axes. I have already read all your various measures concerning the measurements and I checked the tension of the belts, the fluency of the print head and the lubrication of the axles. Everything seems good. I would like to avoid changing the steps and however I did not understand if I should modify the um3.json file or the file 9066.json. I can not find documentation on this but if I understand correctly the um3.json file should remain as it comes with the firmware and all changes must do on the file 9066.json. But I'm not sure. Finally, no recovery system is provided !!! (strange decision!) I exclude to change the original cad file, I use the printer for prototyping parts that will then be produced with traditional methods, so it would be risky to produce parts with incorrect measurements. Thank you for the help you can give me. Giovanni
