  1. Hi I had an issue mid June were the Y axis of the print head was no more held by the sliding blocks and dropped down after 6 months of usage of the printer. I replaced them under warranty, thanks to the French Ultimaker distributor. Today I discovered that one of the sliding block that have been replaced is now not snug any more and the Y axis is going to get out of it, after only 2 months of usage. As it becomes recurrent, it is very annoying and let me think about a design flaw. For a 6 k€ professional grade printer it is a bit of a problem having it
  2. Here's the repaired file of the Printcore Lever. It is optimized for a low shrinkage material, certainly would need testing and tweaking for materials like Polycarb or ABS. UM3CoreClip_PL repaired.stl
  3. I have successfully fixed my print core using the model from Thingiverse in my previous post. The model has to be fixed with Meshmixer (Make Solid feature). I have printed it with ColorFabb HT Clear. But in order to get the dimensional accuracy, I haven't tried to get a clear print (increased material flow and high temps would have increased the dimensions) It should handle without any problem the high temperatures in the enclosed printer. The only point is the stiffness of the HT. It would have been better to print it with transparent PC, with
  4. Hi Smithy Thanks for the feedback. Indeed it's on Thingiverse. I'm just back from my annual leave and didn't had the idea to thingiverse for the model. I will have a try with that one https://www.thingiverse.com/thing:3003778 As I print often with a fully enclosed printer material like ABS, ABS/PC, CPE+ or PC, I'll go for a CPE + print. I let you know
  5. I have the exact problem from time to time with 1 S5 and 2 UM3E. Doing a Cura Connect Reset on both the S5 (hosting the Cura Connect Server) and the faulty UM3E does the trick at the moment.
  6. Hi there I have an issue with a fairly new AA 0.4 Printcore, supplied with my S5 end of Dec '18. It's the secondary AA print core, so it hasn't run many hours and it is in very good condition. The transparent lever has broken, while in the printhead. I have managed to extract the print core out of the printhead and I would like to fix it without buying a brand new print core. Is there any spare parts available for the print cores ? Or is there any CAD file that part, so I can get it printed in SLA ? Thanks for your valuable feed
  7. I have managed to print FormFutura TitanX (ABS) on my S5 without any glass chipping, consistently using Dimafix. If you spray a thick layer of Dimafix on the glass plate, it will protect it and while hot provide the right amount of adhesion. It also works fine with PC and CPE+ For CPE, I still use 3D Lac, but the bed leveling has improved in the last FW version and I nearly don't have anymore first layer too squished on the build plate. Which is the cause of the chipping with CPE.
  8. @burtoogle Thanks for the answer. In the mean time, I've been through the Gcode file, the old way, with Repetier. Indeed when the Z hop only over printed parts is on, there is a z hop inside the part, but no between two parts with the S5. I will check the gcode file generated for the UM3E, as the print is good.
  9. Hi @burtoogle So basically I need to tell the printer to make a Z Hop all the time and it should work, making a Z hop with each retraction ? Then I have two questions : 1) Why the Cura simulation is correct, making the Z Hop with the S5 ? 2) Why the S5 is not performing the Z Hop instructions a least on the first layer ?
  10. Hi to all I have a job which is dual extrusion (ColorFabb XT and Ultimaker TPU) which runs smoothly on UM3E. Unfortunately I can only print 6 pieces at a time for approx 8h print. I need to speed up the order, so I have tried to print 12 pieces at a time on my S5, so I've duplicated the settings on the S5. If I look at the print simulation on Cura, the first layer looks perfect, with a retract + Z Hop when moving over the already printed part of the first layer. Printed on the UM3E, the behavior is the same as simulated in Cura, but on the S5, the
  11. Indeed, very close to the print I get. Except the top layers seems to be fine on my prints.
  12. I have done some more testing on a calibration cube. First I have printed a cube using the CC 0.6 profile instead of an AA 0.4 with modified line width. The result is a bit better after tuning the print temp a bit, as speeds are much lower 45 mm/s default speed instead of 70 mm/s in the AA profile. There is a pretty standard elephant foot at first glance. Not as good as the prints done by @smartavionics, but better. Then I have printed another cube with the AA profile, with 0,55 line width, to match the 0,6 nozzle, and same speeds as i
  13. I have cleaned my extruder, but it was pretty clean already. Nearly no deposits on the knurled wheel. Yesterday night, I have printed a big flat part (300 * 190 * 10 mm), using the same settings as the last posted for the calibration cube. No bulging nor elephant foot at all. I am still using the same spool. I am not convinced it is an extrusion issue. Though I must admit your prints were really good. I will try to use the CC printcore setting on a calibration cube....
  14. @smartavionics Indeed it is way better than my prints. Maybe a calibration issue As far as I know, e steps are an average value, part of the firmware (I have QR3,0 Bondtech extruders on UM3E, so I have to tweak the FW at each upgrade). But is there an easy way to calibrate it and set it on the S5? Usually we have to send an extrude command of x mm of filament, then measure the real length of filament that have been through. Tweaking the FW should be close to the UM3 procedure. Other option is : the extruder is dirty ... I'll have a look t
  15. Just to confirm that it is not a standard elephant foot, but a slicer issue, I have printed a calibration cube with a 2 mm bottom layer thickness. And the issue is on 2 mm height from the build plate .... UMS5_Cube plein test.3mf
  16. I have printed a 30 mm calibration cube with the same settings as in the cura project. the wall and infill layers + top skin layers measure 30,04 mm, but the bottom skin with the "elephant foot" is 30,58 mm. The issue is only on the 5 bottom skin layers, as my settings were 5 bottom layers, after that, the layers tend progressively to reduce to the target size. Given the fact the line width has been set to 0,55mm, there is nearly a full line width added to the bottom skin layers.
  17. HI @smartavionics I have done some more testing, as in my customer project I need to make some text insertions into a board. As I don't want to file / sand every letter in order to fit the board, I am trying to get rid of the "elephant foot". First I confirm it is not a classical elephant foot, but the skin layers being larger than the walls + infill layers. Second, I have the issue also printing with a 0,6 mm nozzle. I have double checked the filament diameter and flow rate. In fact the filament is 2,82 mm for 2,84 mm diameter set in Cura, so the real
  18. OK thanks a lot. So I shouldn't have that issue. Again, printing with a 0,6 mm nozzle with a 0,55 line width on the same printer / hardcore with the same spool / material flow / profile (except line width) / part doesn't create to a larger part on the skin layers.
  19. HI @smartavionics Using wider lines for the infill doesn't save any time, just more material and weight on the print. And yes I have used wider lines : 0,75mm line width for a 0,8 mm nozzle. I've also made a test with a 0,8 mm line width, but it doesn't change the behavior. I may have a go on your suggestion for a 1,00 line width with the 0,8 mm nozzle, but it will increase the pressure in the nozzle so retraction and coasting tuning might be a bit more tricky. Generally, I am setting a lower line width than the nozzle size for these reasons. I think th
  20. UP ! I still have the issue with the bottom layers being oversized using a 0.8 mm nozzle. As there is no issues printing the same part with a 0.6 mm nozzle it may be related to the slicer. I need to print a big flat part in many chunks and a 0.8mm nozzle would save me a lot of time. Has anyone a workaround ? Thanks in advance
  21. I have completed my order, but with some quality issues on the S5. I have played with the combing to realize that retraction was a good culprit as with no combing, I still have the issue on my cylinders and lots of stringing. So I have increased it to 8mm and 35 mm/s, and the result was much better. I have also decreased the temp by 5°C. These setting provide an acceptable but not good print due to striging and still over sized cylinders. Advice much appreciated !
  22. HI to all I am printing a casing for a customer of mine, but as there are many of them ordered, I print on 2 UM3E, 1 UM S5 and a highly modified Mankati XT Plus (Duet3d, Bondtech, E3D V6) All printers are using 0.6 nozzles with ColorFabb PLA Economy White (3dSolex Hardcore for the Ultimaker). I use Simplify 3D for the Mankati slicing and Cura 4,0 for the Ultimakers. I have an issue printing 2 small 2mm pins which are a bit touchy to print with a 0,6 nozzle, but I manage to have something acceptable : Pretty good results on the Mankati
  23. Thanks for the feedback Yes I've checked the filament diameter and it was the right one. I have also played with the flow rate, dropping it to 90%, but with no success. BTW, the very same filament (same spool, same diameter, 100% flow rate as it's PLA) on the same printer, with the same printhead, but a 0.6 nozzle printing the same part does not create the "elephant foot". I have just swapped the nozzle on my 3d Solex Hardcore. So I believe there is something not properly handled in Cura on the solid infill feature.
  24. Here it is ! Thanks for your expertise. UMS5_Cube plein test.3mf
  25. Hi to all I am trying to print with a 0,8 mm nozzle on my S5, using Cura 4,0. I have used the printcore AA 0,8 profile and printed a calibration cube in PLA, 200 microns resolution I have done some tuning on the temps (nozzle and bed) and material flow, but whatever I set, I still have an elephant foot on all the solid infill layers. So the 5 first layers are consistently at 30,5 mm for a cube of 30 mm side, for the rest of the layers I have a 30 mm +/- 0,05 cube. See picture I forgot to mention that printing with a 0,6 no
