  1. Probably a transistor etc. which drives the heated bed is permanently turned on instead of relying on the signal from UM2 to turn it on. Alternatively the transistor is receiving a false signal to it's input which is turning it on. You need to get a technician to have a look and replace the component or you could replace the whole printed circuit board yourself, assuming the transistor is on there. You could try uploading the firmware first in case it's an error in the code. This is a less likely fix but costs nothing to try. Also look at the electronics to see if any wire has come loose or if there is something bridging contacts. Good luck Owen
  2. So I duplicated your settings in Simplify3D and the print lines still seem extremely noticeable. Im not sure if this is just as good as it gets or if I just need to keep tweaking. I just heard so much about the Ultimaker printers that I expected them to be equal or better than the zortrax. I decided to print a little batman bust and when looking straight at it, it looks lovely, all the details are there.. but when you slightly shift your angle you see how pronounced every print line is. Now Im not expecting perfection, but I expect the depth from one print layer to the next to be a little more subtle.. I guess my zortrax has just spoiled me on how well it prints and how seemingly invisible the print lines are. I willing to try whatever and keep printing these test pieces if anyone has any additional suggestions. I don't think that's too bad a print for ABS as it doesn't print as well as NextGen or others. Where you see the very noticeable lines at the top of the shoulders is purely a function of layer height. Lowering layer height will greatly diminish these. You can go down to about 0.04mm layer height or less. Less quite often doesn't make much difference though it might on this section. In S3D you can also print different sections at different layer heights so that you can print fine where you need to without slowing the whole print down. Use the variable settings wizard under the tools menu and change the layer height for each process. Maybe find a smaller model to experiment with.
  3. I've been using S3D with enclosure and door maintaining 45 degrees C Nozzle 250 Bed 100 Fan off till 10 layers (when doing 0.15mm layers) then at 20% Same models were splitting before I used the enclosure Using just enough fan for better overhangs and tops At 50mm/sec. at 0.15mm layers but also printing finer layers and slower speeds with good results I'm sure CURA would print good with the same settings
  4. Unplug anything new that you've plugged in and see if it starts.

    Pause at height to change nozzle size

    Yep possible by that method with Simplify3D and should be in Cura. I printed some Dog Tags. Bottom half 1.7mm high with White XT 0.6mm nozzle. Top half 0.3mm high starting at 1.7mm height of course with Black XT 0.25mm nozzle. The top part had a void for the text so the white showed through. I did it by hanging around when the bottom half finished. Turning the heatbed back on (though you could get the gcode to leave the heatbed on). Swapping the nozzle and purgeing the new filament and then starting the new print. All done in 0.1mm layers. Need to ensure your nozzles are the same height and the top half has Brim turned off. Owen
  6. My pleasure and no offense taken.
  7. Hi Just one drop of oil on the 8mm shafts but not very often Owen

    Post your latest print!

    That vapour polishing doesn't always look that great due to lost detail but it looks perfect on this print.

    Tips and Tricks: XT with S3D

    Sorry to hear about your terrible day fergazz :( I think you might be able to import these settings but if you can't you could just read them and set your settings like that. UM2+ is capable of printing much more volume then the UM2 but also mine tends to over extrude when I print XT which is why I set the extrusion multiplyer to less than 1 but you should leave it at 1. With those settings I printed out White XT and Black XT which both printed well. Good luck.

    Tips and Tricks: XT with S3D

    Hi fergazz These are my settings that I used the other day with good results. Bear in mind I have UM2+ and had my extrusion multiplier set to 0.95 instead of 1. Also I was only printing at 30mm/s. You could see if these settings work for you and then add more temperature and speed as desired.

    is ther a forrum search

  12. I have already upgraded my printer with the |Robert| feeder, an Olsson block hot end with a 30 watt cartridge, and 3dsolex high temp PTFE coupler. Is the included stepper motor different to the UM2 motor? My setup should be able to print at much higher speeds. Even at 35mm/s effective extrusion rate (20mm/min extrusion -> 35mm/s @ 0.4 width, 0.15 layer height) there is under extrusion in the 100mm command. The UM2+ feeder is geared.
  13. I think this is typical characteristics of the the um2 feeder and umo even though there is no noticeable slippage or skipped steps. The upgrade to um2+ greatly alleviates this problem. Other things to do is make sure you have a clean nozzle, have an easy unrestricted entry into the extruder, have the tension adjusted right on the extruder, check the ptfe coupler in your hot end and then always print at a moderate speed like 25 to 35mm/sec.
  14. You should be able to heat the block up with the printer without the nozzle in their and then use your needle again to clean the block.

    Print is not as it should be

    Try turning the print 90 degrees on the bed and see what happens
