  1. I've something weird going on. Yesterday I changed material from pla to abs and made a single color print. When the print is finished the printer retracts all the filament out of the printer and then the head will go to home position. Today I had the same behaviour. I did not have this issue printing with pla. I sliced the model with S3D, but I haven't changed Gcode or anything. Is this a firmware thing? or am I doing something wrong.
  2. @harmenschippers - where do you got the power supply at this price? AFAIK it is (usually) much more expensive... Can you share the source? @tinkergnome - I've bought the power supply at "Koning & Hartman" (dutch store) and the exact amount was €77,15 ex.vat.. ...and can you share some details about how to make the adapter? That would be great! I will share the details how to make one when I'm back this weekend. I've to go in about 10 minutes :-). I will make a drawing and post that later. I will also look up the number of the plug I used. I ordered it from mouser and was around €5.

  4. I recently bought a new PSU just to the test if the printer can work with the original power budget settings. The PSU is a slightly better than the original. - Power supply original: MeanWell GST220A24 - Power supply new: MeanWell GST280A24 (around €75 ex. vat). It comes with a six pin molex plug so I made a 6 to 4 pin adapter cable. You see the only thing changed is the watts from 220W to 280W. Maybe an upgrade of the power supply will improve the stability of the power usage and not using the max of the power supply (if that is the problem). It could be an option to think about when yo
  5. (maybe a stupid question) Do you set the z axis also for extruder 1? if yes, I haven't done that. Just calibrate your buildplate with extruder 1 just how you normally would do and then set the z axis for extruder 2. if not, I haven't said anything...
  6. Have to agree with what foehnsturm has said - there have been a couple of us who have had this problem at the start - once a suitable value has been entered into the Y offset it works superbly For help, my offsets are: X 18.20 Y -24.95 - Maybe good starter input positions? I've done this to solve this issue. Pages 7 and 8 covers most of this problem.
  7. Thanks, I will try with less temperature. For the dual print I used Cura, but normally I work with S3D and for the single color prints I prefer S3D. Good idea SyntaxTerror and I'll add my settings which I've never had problems with on having a shutdown. Using your board (VMT) with extrusion upgrade kit on main head (UM2 Ex) and original UM2 head /extruder as second head - I have changed the temperature probe and heater (40W) to UM2+ specs. My power settings: 160/150/45/45 - hope this helps. I think it's a great idea as well. Maybe it's also good to note what kind of power supply w
  8. I did it ...Got my first dual extrusion print. It came out pretty well. I think I have to calibrate the settings it a little bit. There is a lot of extra filament coming out of the second extruder. I don't know how it's called. When the second head will start it's part of the layer there is always coming some filament out of the nozzle and that messes up the print a little, but I'm still satisfied. My power settings at the moment are 125W/170W/80W/80W. I also pre heated the bed first to 60 degrees, before I started the print. Not intentionally, but I figured that when I was slicing up t
  9. I changed the values for the next print myself in the json file and now it didn't occur. Thanks :-). I hope this one will make it to the end. The settings I gave just gave a immediate power shut off after the bed was heated up. So now I changed the values to 125W/160W/50W/50W. Would it help to get another power supply? or should it just work with the given power supply from MeanWell 221W.
  10. I've installed the firmware and did the calibration. I came across the well known bugs and solved them. The first print I made today went well till the last 1/4 of the print. The UM just stopped. TheFox had this issue as well. I now have changed the power budget from 140W/150W/40W/40W to 125W/150W/40W/40W. Tomorrow I will try this setting. Or do I have to alter the numbers a little more? Also I have this issue... I couldn't find an answer in this thread. Is there a solution for this problem?
  11. Hey Guys, I'm almost done with adding the Mark2 modification on my Ultimaker 2+ extended. It's been going very well. I only have to do some wiring and then I hope I'm able to start calibration this week and do my first 2 color print :-). Just wanted to say that I've printed every part with Ultimaker PC filament and everything went pretty well, but I had to print every part individually for good results. I also printed part "head-a" a little different. I turned it 90 degrees so that the 4 mounting holes are on the bed. I only added support for the big overhang. I also noted that I don't h
  12. Hi, I have a question about printing the needed parts. In the manual it is recommended to print the parts in high temp PLA. That is ok, but will it deform when I want to print something in PC? If yes, is it better to print all the parts in PC? Also somewhere it says that it is a good option to print some parts with semiflex material. What do you recommend and is easy to order for someone living in the Netherlands. Thanks in advance! Really looking forward making this Mark2 upgrade on my Ultimaker 2+ Extended (with 5th motor driver, I checked!)
