  1. The UMO, UMO+, UM2 and so on share the same motion components only the arrangement is slightly different depending on the model so in that regard the problems and solutions would be very similar. I think ill give hydraulic oil a shot and see what that produces. Im trying to track down what is causing a layer shift between 7 and 8 mm only on X axis no matter the model. I suspect this is a factor but I cant seem to figure out what the catalyst is for a layer shift to happen several millimeters in to a print.
  2. On my Ultimaker Original Plus I have been fighting this odd binding issue. When the X and Y along that run along the belts are aligned (I do this very meticulously) the bushings bind against the right side rod only moving away from the front. When motion is applied in towards the front of the unit no binding is present and is very smooth. If I clean the rod after a print the binding is less present but you can slightly feel it. After a print the binding is back. So what im trying to determine is - do the bushings need to be replaced? - did the rods get bent? -do I n
  3. Awesome! Flashing the firmware is a simple affair. Firmware can be downloaded from Ultimaker or you can use a custom one like Amedee's awsome firmware builder found here. Flash in connect the board to your PC via USB and flash in Cura: System -> Maintenance -> Firmware update
  4. Listing here http://ebay.us/ZAXe9H?cmpnId=5338273189 compatible with the Ultimaker 2+/2Ext+, Ultimaker 2 (inc Go and Extended variants), and the Ultimaker Original+. Wanted to give you guys first dibs on it if anyone desperately needed one. Need to be flashed before use as I had VERY custom firmware on it. I replaced mine with a Duet2 Maestro. All working with zero issues. Does have some browning around the stepper drivers but this seems to be common with these boards after some use.
  5. I have been playing with firmware as of late on my Ultimaker Maker Original Plus. Yesterday a print failed to thermal runaway. My first thought was it was something I did wrong in the firmware to cause a bad reading. So Today I attempted to go through some general health checks on the printer. Make sure fans work, hotend, and so on. When I attempted to to heat the bed it generated a thermal runaway error yet again. Time to hardware bash and check all the connections. Only took 5 seconds to find the problem. (see Pic). This printer is roughly 3 years old? On close inspection I noted
  6. Looks like a simple google "understanding marlin" turned up most of the good info for understanding the basics.
  7. I suppose what im trying to achieve is a firmware with the same feature set I currently have while having the ability to add sensors or just simply continue on without starting over from scratch. It seems however that is exactly what needs to happen. I can start with the Armedee or Ultimaker base firmware and modify from there. I simply need to get over the learning curve of Marlin in general. Can anyone recommend a good intro source to understanding marlin's layout and definitions other than the Wiki and git?
  8. Howdy folks its been a while. Since I have modified my UMO+ heavily I have found joy in custom firmware and its merits when the need arises to make changes. My favorite has been AmadeeBulle / Marlin found here https://bultimaker.bulles.eu/ . Up to this point this very well made firmware builder has suited my every need. I have hit an impasse however due to my own personal limitations. To the novice like myself Marlin can be a bit daunting. The builders have me somewhat spoiled. Now I need to modify it again yet my builder of choice offers no such option. From my understanding I only have
  9. Good point amedee. I was eluding to the cooling on my setup in particular. I have a Original Prusa MK2 with E3D v6 hotend and prints small PLA models fine. Seeing as that's virtually the same hotend only a 1.75mm version I am suspect that the fans simply are not cooling the PLA enough. Perhaps my choice in hotend mount and fans has something to do with my results. Do you think a fan with higher flow would help?
  10. Following up with my project. I have added a 40mm 5v Noctua fan to the E3D cooling duct with a shallow adapter. This works as well as I would have hoped. The fan is now board controlled and all 3 fans are whisper quiet. I have tested this out with a few PLA prints and I can see what ultiarjan was talking about with the upgrade effecting PLA print quality. Any small prints with the eSun pla + is simply to hot to hold a form and ends up with some deformations. Large prints however perform fantastically. So PLA is still fine for this as long as its something larger than a Benchy. I have yet to
  11. Pulled the fan off to be sure its 24v and yes it is. So connected to J20 (Fan 19-24v) out. J14 Fan_pwm is being used by the part cooling fans. This means the v6 fan is on always with power. Would be great if I can figure out a way to temp control that fan. You recommendation to the custom firmware was spot on. Thanks for that.
  12. Well technically I have two of them now. I have a 12v version that came off my Prusa and I assume a 24v that came with my kit? I ordered the 24v kit. I reread the wiki again and I guess I missed understood. So there is a second 24v output on that board?
  13. So I made the plunge to update my UMO+ with a V6 hotend. There are many ways to go about this it turns out and none of them are exactly straight forward. So I chose my mod and proceeded. I chose a dual fan mount for my hotend https://www.youmagine.com/designs/e3d-v6-hot-end-mount and some new blocks to compinsate the new clearance requirements https://www.youmagine.com/designs/ultimaker-xy-blocks-with-banana-tensioner I decided on some Noctua fans for the efficiency and low noise. 40mm NF-A4x10 FLX http://noctua.at/en/products/fan And of course the E3d V6 kit. http://e3d-online.com/
