  1. I decided to build a UM2 clone and not surprisingly I am running into problems. Got it assembled and installed the marlin firmware. Using Cura 2.4 and "Automatically upgrade Firmware" When going through the first start up after the last window after you push the button for the last time I get "Z switch broken" and nothing else happens from there. I have metered out the mother bd and am confident it is not a physical switch or mb problem. The mother bd is a 2.1.4. Anyone have any ideas/solutions?
  2. Thanks but it ws a new bd. First time I re-programmed it. I did a build with Arduino. Exported the binary files of which I got 2. One had bootloader in the title. Wrong one to try to program the bd with. Have not been able to communicate with it since.
  3. Here is my latest progress. Managed to program another bd with Arduino. Still cannot program my bad bd. The programmable one has a bad Z switch. Only thing I observe is one bd connects to port 6 the other to port 5 even though I am using the same usb plug on my PC. Could not program any bd with cura 15.4 but could with 2.4 Pronterface only has port 1 and 3. Waiting for my laptop to charge up to try that.
  4. Ok here is my progress. I have used 2 different usb cables. Successfully programmed an Arduino when I though I need to reload the bootloader. Have just tried Cura 15.04 with the same results. The bd still shows up in Device manager when I turn it on and off. Tried unplugging the usb as suggested; did not help.
  5. It is a UM2 I cannot upload the standard firmware now. Was trying to up load custom firmware when things went sideways. Trying to add a Diamond Hotend. 3 in 1 out. I have tried Cura 2.4 and 15.4. Hope this helps. Thanks for your time
  6. While updating firmware on my mother bd something went wrong. Now it will not communicate. The motherboard shows up in printers and devices but when trying to reprogram with Cura it instructs me to plug in the printer. I though it was bricked but from researching this it must not be if my computer sees it. Any thoughts sugestions?
  7. I am using Cura 2.4 to upload custom firmware. The standard firmware updates fine. I cannot find the config hex file in the folder when I open it. My question/problem is how do I crate a hex file to upload?
  8. I wish to print using three colors so am adapting the Diamond Hotend to fit. Just discovered that the original Ultimaker bearings do not fit. Too short and not correct od. Anyone got any tips on using this hotend?
  9. I purchased and assembled a Ulimaker Original + kit. Go it working after a few hiccups. The big problem now is that I getting visible lines in my prints (100 microns) and occasional separation at the lines. These lines have always been at the same height. UM support has not figured it out. The suggested going up on nozzle temp and down on print speed. Worked for a while until I changed filament. I re-did the z axis bearing seating procedure and the line seems to have moved up just a little but is still there. This is my third kit I have built. The previous two were from China and you get what you pay for sure held true. I expected a lot better from this printer. I think this can be a great printer once I get this straightened out but it sure needs some help. Any one else expereaince this or have any ideas?
