KEEVO V2.0 Hello again, I finally was able to update the project and bring it to a state which I now consider finished (although no printer is really ever "finished" :- ) ) I am very happy with the end result and has proven to be a reliable machine. keevo2_turntable.gif mod_embed_images_loadimage('bdf108931a08509a64815032b16bdada', '/forum/thumbcache/cf4/cf2/5cc/758/f15/ec8/40b/8f2/689/f38/30_800x400.gif', 'http://nuverian.net/files/keevo/keevo2_turntable.gif', 'https://reprap.org/forum/addon.php?397,module=embed_images,check_scaling=1,url=http%3A%2F%2Fnuverian.net%2Ffiles%2Fkeevo%2Fkeevo2_turntable.gif', '', 875794, 800, 400, 'Loading image ...', false); 1596205858174-isofrontphoto.jpg mod_embed_images_loadimage('c0854d0a58efa87294becd900545f821', '/forum/thumbcache/fbb/bb2/f22/11a/004/dea/d98/351/890/2d7/92_800x400.png', 'https://forum.duet3d.com/assets/uploads/files/1596205858174-isofrontphoto.jpg', 'https://reprap.org/forum/addon.php?397,module=embed_images,check_scaling=1,url=https%3A%2F%2Fforum.duet3d.com%2Fassets%2Fuploads%2Ffiles%2F1596205858174-isofrontphoto.jpg', '', 875794, 800, 400, 'Loading image ...', false); 1596205880742-backelectronics.jpg mod_embed_images_loadimage('f48f9134bbce73bca9f90035b36ee7cc', '/forum/thumbcache/5e3/11e/951/10d/f15/79c/2d1/8b4/505/6ce/92_800x400.png', 'https://forum.duet3d.com/assets/uploads/files/1596205880742-backelectronics.jpg', 'https://reprap.org/forum/addon.php?397,module=embed_images,check_scaling=1,url=https%3A%2F%2Fforum.duet3d.com%2Fassets%2Fuploads%2Ffiles%2F1596205880742-backelectronics.jpg', '', 875794, 800, 400, 'Loading image ...', false); 1596205858166-coolphoto.jpg mod_embed_images_loadimage('036f3b806c25e828a6a634f040c3cc10', '/forum/thumbcache/181/c3f/ee4/cbe/742/550/84c/adb/5d7/7e3/9a_800x400.png', 'https://forum.duet3d.com/assets/uploads/files/1596205858166-coolphoto.jpg', 'https://reprap.org/forum/addon.php?397,module=embed_images,check_scaling=1,url=https%3A%2F%2Fforum.duet3d.com%2Fassets%2Fuploads%2Ffiles%2F1596205858166-coolphoto.jpg', '', 875794, 800, 400, 'Loading image ...', false); Some KEEVO printed parts: 1596206048155-keevo-printed.jpg mod_embed_images_loadimage('f56e654c1eec1efec785a0273818709b', '/forum/thumbcache/cd4/57c/a94/c7a/bcb/cc3/4cf/d3e/fea/cfb/12_800x400.png', 'https://forum.duet3d.com/assets/uploads/files/1596206048155-keevo-printed.jpg', 'https://reprap.org/forum/addon.php?397,module=embed_images,check_scaling=1,url=https%3A%2F%2Fforum.duet3d.com%2Fassets%2Fuploads%2Ffiles%2F1596206048155-keevo-printed.jpg', '', 875794, 800, 400, 'Loading image ...', false); I hope you like it.

Thank you, I am glad you like those! If you end up building it or a derivative I would be glad to know how it turned out :)
Regarding direct drive, just because of the typical weight/space reasons, plus I don't really print flexibles which I see as the only good reason to use a direct drive.
Even so, if I ever am to convert keevo to a direct drive, I would first try out using a flex3drive though for sure.

Yeah, I actually see the main benefit of the flex3drive being that you can use a full-sized stepper motor instead of a pancake one and your stepper motor doesn't suffer from the heat of the hotend and bed. I'm working on another closed printer and the direct-drive system I was using got so hot it melted the plastic extruder. So now I converted it to bowden with an all-metal extruder and it works. In time I might come back to making it direct drive again, but flex3drive looks interesting as well. If I can justify the cost some day I just might!

Found back the old drawings from 2014 or so so I have some basis to work with :)
Here's a video of the machine working as a laser cutter:

Wow, looking good. I might, in time, rebuild my CoreXY design when I have the funds and the time. It looks like you got it down. Do you have more examples of the prints it makes?

Thanks!
Here are some recent prints I did for 1/72 wargaming scenery (thus quite small).
These are printed rather fast, with 0.5 perimeter width (and nozzle) and 0.3 layer height. I am an impatient guy :)

Wow, looking very impressive. Now that's inspiring to me to rebuild this printer... I have a wonderful frame, but the insides are just not constructed well. I think the outside size is like 390x390x390mm so it won't be a super large build volume, however, I might be able to reuse the parts from my MendelMax to fit inside. Two linear slides for the Y-movement and two rods for the X-movement. For the Z-axis I have three acme screws laying around that I could use, and some leftover linear rods to guide the Z-stage.

Is there any reason why you didn't opt for a direct drive extruder?]]> Ohmarinus CoreXY Machines Mon, 10 Aug 2020 17:38:15 -0400 https://reprap.org/forum/read.php?397,875794,875983#msg-875983 Re: KEEVO V2.0 https://reprap.org/forum/read.php?397,875794,875983#msg-875983

Hi nuverian, it seams a very nice machine. My prototipe is simlar to yours and you solved some issues I have in a good way.
I've just a question: until yesterday there was some picture of the XY motors mount aligned on Y axis like your older Tribotron. In the current project you aded an idler and motors are been shifted. Is there a technical reason for that.

Hey, Thanks. I am glad you like it and it helped in your design :)
I accidentally uploaded the old version gif in my initial post (where the motors are mounted on the back), this is why I editing the post to re-upload the correct gif (which is the one shown now that has the motors shifted and placed in the backside inset).
The main reason for the new motor placement is so that they are placed within the back frame inset and thus not take more space on the back (sticking out). As such the whole printer has less depth (y) and can be placed closer against a wall. Thus it is a matter of making the machine a bit more compact. Additionally, the old motor brackets were ever so slightly bending over belt tension, whereas the new motor brackets do not.]]> nuverian CoreXY Machines Wed, 05 Aug 2020 11:40:35 -0400 https://reprap.org/forum/read.php?397,875794,875849#msg-875849 Re: KEEVO V2.0 https://reprap.org/forum/read.php?397,875794,875849#msg-875849 I've just a question: until yesterday there was some picture of the XY motors mount aligned on Y axis like your older Tribotron.

Nice!

Thanks!
