  1. Is there a thread where we share all our best Cura Profile Settings or where can I look up These (e.g. There was once a Profile for Thin walled objects like Vase) ?
  2. Thanks a lot for the tips! I changed the Filament and now it works again. It was a new roll of white PLA from German RepRap. The Diameter seems ok ~2,90 but it didn't work for some reason (maybe also humidity???). On the other Hand I'm still not 100% sure if that was the main reason because in my Panic Phase I changed things in parallel (nozzle, Extruder bolt). When I have more time I will try to examine the Filament again - but for now the risk is too high because I have 4-5 hours prints to do!

    Skewed/leaning Prints

    I have had this too, before. Like gr5 said, it is a rubbing/friction issue. Be sure to oil your rods from time to time. I always have a tube of oil besides my UM. I am a bit paranoid, but I oil the rods every 3 hours or so...
  4. Hi community! i am facing a problem which i can't solve by my own anymore, so please help! I have been using my UM since over a year now, without any Major Problems. But now since a few days my Printer will stop extruding after printing a few layers (see pic). After I stop the machine then, I could still extrude the Filament by Hand. So this is what I have done so far: - Demounting the nozzle (see pic), in my opinion no clogging - though the Filament Looks weird, it is hollow until the upper end of the hotend brass part, before demounting the nozzle I retracted the Filament by Hand when it was still hot. (see pics) - Tightening the Extruder spring until 12mm length - still I see chewing on the Filament (see pics) - Smoothing the bowden tube with oil - PLA printing with high Quality Profile, at 240°C (normally 205°C) What else could i do to print again? The last days i was printing objects with a lot of retraction, could that be a reason? I am using: - Hot end v2 - Extruder spring design v3 Cheers and thanks, Andreas

    NetFabb 4.9.4 - Update Issue Thread

    I wouldn't wanna say that netfabb is bad. Quite the contrary, I am using netfabb for 90% of my prints. In my opinion it is outstanding when it comes to very detailed small prints in ultra quality. Cura isn't there yet. The only ting i would like to claim is the customer support. It could be much better (Proactive information on updates, reaction time on requests,...)

    NetFabb 4.9.4 - Update Issue Thread

    Hi Alexander, thanks for your hints! A reset of the machine settings made it work again! And retraction seems to work! A few more questions: The start sequence is a bit weird - the head moves to the very right X position, starting to draw Y lines. Does this have to be necessariliy or what is the clue behind? Im asking because this movement leads to a endstop hit (at least I guess it does) and therefore the print starts at a complete different position than defined. The other question is about temperature of the new material styles. They all run with higher temperatures than before (e.g. Ultra starting at 205°C, before at 190°C). Is this on purpose? Thanks for your response! cheers, almi

    NetFabb 4.9.4 - Update Issue Thread

    Hi Sonarok, you are not the only one facing problems with new new 4.9.4 version! This isn't the christmas present it was supposed to be. It is producing really weird gcode concerning the E step calculation. The E steps seem to be running to infinity! Printing with this gcode leads to a massive extrusion of course! Please help me! What am I doing wrong or is there a huge bug in 4.9.4 ?? Also the update was released without any documentation... This isn't very customer friendly! Although I appreciate the effort to come up with a new version right before christmas... But I am not able to print anymore with netfabb!!! Here is my example of gcode: M106 M109 G28 G92 X0.0000 Y0.0000 Z0.0000 E0.0000 G1 E0.0000 M107 M104 S193.0000 M104 S185.0000 G1 X-4.0000 Y-4.0000 Z0.5000 F480.0000 E28.3945 G1 X20.0000 Y-4.0000 Z0.5000 F480.0000 E176.7891 G1 X20.0000 Y20.0000 Z0.5000 F480.0000 E473.5782 G1 X-4.0000 Y20.0000 Z0.5000 F480.0000 E1067.1564 G1 X-4.0000 Y0.0000 Z0.5000 F480.0000 E2234.3127 M104 S193.0000 M140 S0 (begin layer 1 at 0.060) M140 S0 G1 X1.5010 Y1.5010 Z0.0600 F10800.0000 E4468.6255 G1 X2.1026 Y0.9954 Z0.0600 F600.0000 E8937.3701 G1 X2.7801 Y0.6042 Z0.0600 F600.0000 E17874.8594 G1 X3.5326 Y0.3332 Z0.0600 F600.0000 E35749.8398 G1 X4.2898 Y0.2000 Z0.0600 F600.0000 E71499.7969 G1 X5.0740 Y0.2000 Z0.0600 F600.0000 E142999.7187 G1 X5.8480 Y0.3362 Z0.0600 F600.0000 E285999.5625 G1 X7.0221 Y0.8575 Z0.0600 F600.0000 E571999.3125 G1 X6.4350 Y1.4440 Z0.0600 F600.0000 E1143998.7500 G1 X5.6740 Y1.1100 Z0.0600 F600.0000 E2287997.5000 G1 X5.0260 Y0.9880 Z0.0600 F600.0000 E4575995.0000 G1 X3.7220 Y1.0990 Z0.0600 F600.0000 E9151990.0000 G1 X2.5550 Y1.6430 Z0.0600 F600.0000 E18303980.0000 G1 X1.6440 Y2.5550 Z0.0600 F600.0000 E36607960.0000 G1 X1.0990 Y3.7220 Z0.0600 F600.0000 E73215920.0000 G1 X0.9860 Y5.0050 Z0.0600 F600.0000 E146431840.0000 G1 X1.3200 Y6.2510 Z0.0600 F600.0000 E292863680.0000 G1 X2.0560 Y7.3040 Z0.0600 F600.0000 E585727360.0000 G1 X3.1140 Y8.0440 Z0.0600 F600.0000 E1171454720.0000 G1 X4.3240 Y8.3720 Z0.0600 F600.0000 E2342909440.0000 G1 X5.6760 Y8.2540 Z0.0600 F600.0000 E4685818880.0000 G1 X6.8360 Y7.6980 Z0.0600 F600.0000 E9371637760.0000 G1 X7.7200 Y6.8100 Z0.0600 F600.0000 E18743275520.0000 G1 X8.2540 Y5.6760 Z0.0600 F600.0000 E37486551040.0000 G1 X8.3760 Y4.3380 Z0.0600 F600.0000 E74973102080.0000 G1 X8.2560 Y3.6940 Z0.0600 F600.0000 E149946204160.0000 G1 X7.9198 Y2.9292 Z0.0600 F600.0000 E299892408320.0000 G1 X8.5071 Y2.3424 Z0.0600 F600.0000 E599784816640.0000 G1 X9.0278 Y3.5170 Z0.0600 F600.0000 E1199569633280.0000 G1 X9.1640 Y4.2902 Z0.0600 F600.0000 E2399139266560.0000 G1 X9.1640 Y5.0738 Z0.0600 F600.0000 E4798278533120.0000 G1 X9.0278 Y5.8480 Z0.0600 F600.0000 E9596557066240.0000
  8. Hi all, thanks for your solutions! Indeed one of my short belts went sloppy. And additionally, my rods were dry after hours of printing. So I guess this all led to loss of steps. I will now try to make the short belt tensioner posted on thingiverse, and will use machine oil for oiling my rods instead of the grease shipped with UM, because out of my experience this grease will be pushed away by the bearings soon. Thanks for your great support! almi
  9. Hi all, please help me out with the following issue. I have a relatively huge object to print. After 2-3 hours of printing the Ultimaker somehow looses its positions of Gcode and moves sidewards into one direction. First I thought of an issue with the endstop, but then I printed another small object with the same issue which cannot reach the endstops at all. This happened now 4 times witth the same object, always at about the same height. Is it a mechanical problem or a fault by the slicer? The gcode was done by netfabb. Could it be an underrun of cpu buffer? Please help me. Thanks, almi

    Support structure options

    Thanks, Robert that is the solution! Cheers, Andreas
  11. Hi all! Maybe somebody could help me with the support structure settings in netfabb. I want to avoid the first layers of basic support on the platform, which netfabb always does, no matter what kind of support settings I choose. It is because this basic structure leads to fails in the first layers of my object itself, and it is not necessary at all, because my object doesn't have overhangs in the lower parts, it is totally flat at the bottom and fits perfect on the plattform. Though, my object has 90° overhangs in the upper part, so I need a support structure there for sure. How can I avoid the basic platform support structures, but still have a real support structure at the upper parts of my objects? Any settings which I have missed? Thanks for any hints and tipps, Andreas
  12. Hi community, I am facing problems using the blue translucent PLA bought from the Ultimaker Shop. Thankfully with this material you can see any extrusion problems very good because when a problem occurs, the color changes from blue to a sort of white transparent, as you can see on the picture, my part has this on the top section (picture left side), but also on the bottom (where the part was lying on the platform, picture right side). It stopped extrusion after it changed the color. I was using netfabb High Quality profile to slice, and changed the material profile "PLA - High" to a temperature range of 230-238. Printing was done with RepG 035. What could I do to improve that? Increasing temperature to 245? Driving even with lower speed than the High Quality profile netfabb defines? Thanks for any tips and inspiration. almi

    Back Lash compensation needed!!

    Thanks Owen. I now solved the issue. The M501 command only works with the Marlin firmware. In my case, for what reason ever I thought I had Marlin on, but actually it was a Sprinter version. Now that I have Marlin on, I receive full EEPROm information after the M501 command. So now I can try the X, Y Axes compensation. Thanks, almi

    Back Lash compensation needed!!

    I also tried to retrieve the EEPROM parameters in RepG (By sending an M501 command via GCODE dummy file) and got following: "Couldn't show onboard paramters, driver doesn't implement onboard parameters" Now I am using the Marlin Build 3 from Bernhard Kubicek. What driver do you use? sending: N4 T0 M105 *71 [22] received: ok t:51.27, raw:105 b:0.00 [22] sending: N5 M501 *2 [22] received: ok [22] sending: N6 M108 S0 *79 [22] received: ok [22] Scheduling machine state change event: READY [22] Machine state changed to BUILDING [22] Yes, I have a Realtime Control feature. [22] Sending machine state change event: BUILDING [22] Machine state changed to READY [22] Supports RC [22] Couldn't show onboard parameters: [driver doesn't implement onboard parameters] [22] Yes, I have a Realtime Control feature. [22] Supports RC [22] Sending machine state change event: READY [22] Done building.

    Back Lash compensation needed!!

    Owen, thanks for hints on calibrating the X,Y values. I would wanna give it a try on my machine, too. But of course need my actual values. Your tip was "send M501 to view what they are currently". I have sent M501 in printrun and it won't show me any information about the actual EEPROM values. What went wrong? Any initial command to be sent for retrieving the data? Thanks for any hint and cheers, almi
