  1. As it turned out I simply wasn´ t patient enough. As soon as the buildplate is getting close to the desired temperature (about 2°C below) the nozzle starts heating up as well. This is also the point at which the endtemperature of the nozzle switches from 0°C to the desired 200°C. This is what caused the confusion on my behalf, as I did not expect the end temperature to change at any point. Thanks anyway for helping!
  2. Finally got to try it out and it does exactly what I hoped for. I really start loving your firmware more and more. It´ s also great to see that much support in the community. Big ups to you!
  3. This sounds like a perfect solution. I will try and see how it goes. Thanks again for the help, remind me of the beer if it works!
  4. Even though low temperature printing works great now, I did notice another issue. If I am trying to print with PLA (settings: nozzle 200°C, bed 60°C) only the bed is heating up and if I move the cursor on the nozzle temperature it shows something like 26°C / 0°C. There still is the obvious workaround of setting the nozzle temperature manually but I would be very happy if there´ s a way to solve this properly. @tinkergnome could you help me out once more?
  5. By the way, I also discovered that there is an option to include "virtual endstops". This sounds like a pretty good solution as well, especially as the hardware modification would not be needed anymore. If this means I have to sacrifice a little bit of extra safety I would be fine with it.
  6. Hi everyone! Before I start off: I am working with an UM2+, Cura 4.3.0 on Windows 10 and the tinkergnome UM2+ firmware. I am currently working on a university project. The aim is to convert the regular UM2+ into a printer which can do both regular and bio-printing (bio-printing is in short words the printing of hydrogel in which you can implement cells, so you can print organic material in every desired form). To achieve this I already designed and printed a syringe pump which is driven by more or less the same stepper motor the current extruder is using. This makes it possible to switch from regular to bioprinting by unplugging the extruder motor and plugging in the syringe pump. This leads to my question: In order to keep the syringe pump from crashing every time the syringe gets empty, I want to include two endstops for the extruder motor. I already took a look into TinkerGnome´ s Firmware and I could imagine that it should be possible to include the endstops within the definition of the regular endstops. The desired reaction would be to pause the current print until the material "is changed". What I am asking for at this point is experience. Has anyone ever tried to do this and could maybe even help me out with some code advises? I have some programming experience, but mostly with Java and Python so I could really use some help. Especially as the firmware is pretty huge and I am not sure which files have to be edited to make this work. Also I am not entirely sure how to compile and upload the edited firmware. I tried setting up the regular Marlin firmware (the way it was explained in a YT tutorial) but all I got was a huge bunch of errors on the Arduino IDE, mostly Index out of bounds... I know I am asking for a lot and I could totally understand if nobody is willing to put that much effort into a stranger´ s project. But I promise if you can help me and I should ever run into you in real life I will buy you a couple of beers! Cheers, Max
  7. Hi everyone! First things first: I am working with an Ultimaker 2+, Cura 4.3.0 on Windows 10 and the recommended TinkerGnome Firmware on my printer. This problem needs some help and I would be grateful if you could provide it. As mentioned in the title I recently added a new custom material to my Ultimaker 2+ via the export/edit .txt file/import from SD card method. The idea is to design a material which needs no heating up of either the nozzle or the print bed, as I plugged a selfmade syringe pump to the extruder 1 output in the process of converting the printer into a bioprinter for an university project. Editing and importing the material worked just fine and when I am using the default materials the extruder works just fine as well. As soon as I switch to the custom material though, the extruder stepper motor simply does not move a Millimeter. Here is the edited .txt file (I marked the custom part at the bottom orange) and the fist couple lines of the gcode: .txt file
