What are some of the the best temp and speed settings so far?



  • Anyone find any good settings yet?



  • Wondering if you are using the software that came on the SD card? It has a profile for the CR-6 SE which has been working great with the white PLA that came with printer. 200C for printer and 60C for bed. It almost sounds like you downloaded software from website...which is what I did cause I didn't notice the toolbox drawer with the SD card. My first print was benchy with website software which didn't stick and after a few tries when it did was a stringy mess. Switched to software on SD card and print stuck to bed and came out great. Many successful prints after including iris box various emmett gear prints.



  • @jim_s This are the settings I am using in Cura 4.7, I pulled the gcode out of what they had for the cr6 in 4.2.1 that came on the SD card. (please note that Printhead X min and Y min have some strange behavior for me. In 4.2.1 they are listed as positive numbers, but you can't seem to use positive numbers in 4.7?) Also of note; the auto bed level seems to have more in common with manual mesh bedleveling than it does with traditional sensor based bed leveling. The bed level can only be run from the touch pad from what I can tell, so it doesn't run it at the beginning of every print, even with the gcode telling it to probe.

  • @djanitor Can you share what you're using for the start/end gcode? I haven't found anything definitive anywhere, except the note to use G28 w/o any params.

    If you're willing to share, I'm sure it'd help a number of folks out! (I'd like to see what you're using, as well, as mine is just a copy of what I use on another printer, w/ the modified G28 line...)



  • @jim_s I am having reasonable luck with the ender 3 profiles. I create an ender 3 in Cura, and then replace the machine settings with the cr6 start/end gcode and then have the the 4 default print profiles from the ender 3 available.



  • I can state that 200 deg is too hot for the white PLA that came with the printer - lots of stringing between vertical parts on a Benchy print - looked like Benchy had been through a haunted house. The external surface was pretty nice at .2mm layer height, though - I think this is going to print really nicely once the slicer settings are dialed in!

    Far and away the quietest FDM printer I've ever seen - the cooling fan in the base for the controller board is the loudest part of the whole thing, and even it is not bad. The steppers are pretty much silent. The auto-leveling is seriously awesome.

    We should probably start a thread with slicer settings - that seems to be a big failing of the release of this thing - nobody seems to have published any profiles for popular slicers (and the Creality Slicer doesn't list the CR-6 as an option), or even any generic starting point settings. I used Slic3r with a slightly modified profile from my Monoprice Maker Select, and that seems like a decent starting point, but clearly some tweaking to be done. (Just done the one Benchy print so far...)



  • Hi @letsbet20, maybe most people haven't received the printer yet.👍
