  1. Thanks for input, I will give it a try and run some different extrusion lengths using a slow speed, and see what results that gets me 🙂
  2. Hi I've spent the evening working with estep calibration on my UM2+ Below are the results. I hope you understand the data 🙂 The time the extruder ran was as perfect as I could measure each time. (And it seems my response time is always very close to 0.15 seconds 😉 ) First of all a notice on what I assume is some kind of bug. The first extrusion run after every M92 change of the estep value, gives a way off result. So, I have tested three extrusion lengths 100mm, 200mm and 300mm. It seems the longer extrusion run, the less filament is extruded. So, at the third and last setting in the data below, at E100, I tend to get 101-102mm, at E200, it's more or less spot on, and at E300, it is 2-4mm too short. So, where talking about +- 2%. Is that a normal variation? Though the variation seems to be related to the extruded length, so it is not random. Starting off with default estep = 369 E369 E200 F500 216mm E200 F1000 206mm E100 F100 203mm E100 F100 102mm E200 F1000 204mm 12s E200 F1000 204mm 12s E200 F500 204mm 24s E100 F500 103mm 12s E100 F100 103mm 60s E200 F750 205mm E200 F750 205mm 16s E200 F750 205mm 16s M92 360 E200 F750 137mm 11s !!!!!

  3. Hi Will Tinker "get rid" of the materials functionality in the printer, so that the temp and retractionsettings etc from Cura will take precedence?
  4. Still a problem that it isn't expained by the tooltip....

    UM2+ FW

    Ok, thanks! Then the used UM2+ I got today has the latest FW. Good :)

    UM2+ FW

    Hi What's the latest FW version for the UM2+? Thanks!
  7. Thanks, I'll keep that in mind!
  8. Thanks. I have no specific reason to suspect anything was tampered with, I just wondered about the numbers, and that it seemed to be a big difference. And then there could be a good explanation, if the printer has been used with USB interface, I understand it may have been running for close to 400h rather than 9h. I guess the amount of original filament remaining, will give me a hint on this 😉
  9. Any risk the hours meter has been reset, by firmware update or the like?
  10. Thanks! That's great. I think I'll be buying this one then :) So 3 meters of filament i 8h44m is about 5,7mm filament / minute I guess that is a normal consumption then.
  11. Hi When the printer shows the following runtime stats, what does that actually mean? Machine on for: 389:57 Printing 8:44 Mat: 3m Thanks!
