  1. Well. Hmm. Thanks for the link. I read through it all and didn't really think it was worth it. Yes. I print as fast as possible. My printer differs from Um2 mostly by structure. There may be more to it! I currently don't agree that lowering the temperature is the best option and said in the same line, I would rather try to keep the speed up and think of adjusting the model to fit the printer. Much as I'm used to from my engineering background.
  2. Sorry if I pay in a bit late here. Part of the reasons may be the 3D software that generates the stl file. I have several 3D drawing software and they all have their pros and cons. And they all generate the transfer to STL diffidently. I come from machining, so g-code isn't news to me. To say it frankly, we should not rely on STL to generate the g-code. Which in fact is more M- code . Smartcam used to be the preferred code. I'm not sure who's in game nowadays. A couple of years ago I touched Delcam. Wouw, what a powerful tool.. Well, we may have to give 3D printers for free to a bunch of 3d software programmers in order to get slicers that are capable of turning filaments off and on per perimeter.
  3. Hmmm. There are many drafting software out there, each with their own benefit to whoever user. Going for budget CAD software that works, my vote goes to VariCad. I work in a company that has so many cad users on all levels, that I can always ask to check out something. Now, being used to use CAD/CAM since apprentice ( early 90is ) and with a solid understanding of physics and a hands on experience with the real capabilities of production machinery ( cut, bend, fold, mill, drill, turn, ...ect) Cubify looks interesting. But go for the 200 $ design rather than the intro version. Variacad is currently around 600 euro for a full version for the first year. Update turns out around 100-150 yearly pending on what you sign up for. My company pays for my inventor and solidsworks. But I don't use them that much. For the 3d printing purpose I am still in the testing. I can see that it certainly matters from which console you generate the STL file. Honestly I would rather do without STL. Its a format that isn't really suitable for the printing we want. It cuts corners, so to say. I grew up with SmartCam... Now there was a machine control system. But yes, it's not free! Delcam used to be a company I admired. The shapes the software was capable of and the direct translation to machine language. Stunning! Then someone bought them out. I guess my finish line should be, don't worry about software if you haven't been trained in using it. Second, there's a STL translator in all, that's what we should worry about in the first place.

  4. Hi, and Happy new year all. How does the temperature feedback work? I'm curious because I'm always off the rest of you regarding temperature. I have to remind you that my printer is a KorBot but should not be a lot different from the UM2. I live in Singapore. Ambient temperature is almost constantly 29 - 33 Celsius in the room where the printer resides. Thinking that the KorBot is out of Korea, and generally UM2 is also from non tropical zone, does that make any influence in how the temperature feedback is computed in the firmware? ? Not sure how to describe it either. A normally good looking print with PLA is 245 nozzle temp, 75 bed temp, 100-120mm/sec and fan off the first couple of layers, then half speed the rest of print. And yes, it's Cura slicing software for the KorBot too. I can't make up my mnd wether to us UM or Marlin settings, but definitely not sure reprap or whatever the last solution is. Thanks for a great insight. BR, Daniel
