Hi all 
does somebody know of an open source project for CoreXY 3D printer? my scrap built printer has reached its physical limits, so I’m planning a new construction, and I’m fascinated by the CoreXY movement 
I will send you over my files. It is a wip so the cad version I have now is outdated. I plan to finalize it after I finish testing my latest changes.
What’s your preferred cad format.
woah, Thanks! I’m a solidworks user, so .sldprt would be great! (i have openscad but I never had the time to learn it) I hope I can help you testing the design and adding parts, if you want. I have a year experience with solidworks and designing for printing…
@Arturo_Farolfi I will work on updating the assembly over the next week with my current status. I would love help upgrading the model and making improvements.
Here is a link to my models back when it was hbot. It has since been converted to corexy. But they could give you an idea of my build before I get things updated: https://plus.google.com/109092260040411784841/posts/eTSfSxfnWRw
Model links are down in the comments.
@Arturo_Farolfi here are some pictures of the new y-end pieces I am working on (with some scrap rods between them to confirm fit and parallel). missing/deleted image from Google+
This is going to add 3" or more to my usable Z once I finish designing the x cart where I will be placing dual extruders.
fantastic work +Eric Lien ! sadly I’m limited to solidworks 2007, so I’ll have to use the step files… anyway, i have a final due this week, so I’ll be busy for a couple of days, then I’ll be back.
While not as elegant as Eric’s bot. This a CoerXY open source printer.
@Wayne_Friedt , the u conduit is a conventional H bot, not a true core xy
@Eric_Moy Thanks for the correction. Sorry for leading people astray with my subpar information
mine is still a work in progress, but does print very nicely… http://wolfmanjm.github.io/wolfhbot/
@Wolfmanjm why did I not know about your well documented machine before? I’ve always drawn a blank when people have asked about corexy designs in the past.
@Tim_Rastall well I haven’t publicized it much as I am constantly hacking at it. My Delta (aka wolfstock) is done and several people have built it. I am quite happy with the corexy now, but I think one more redesign of the X gantry is in order, then I’ll finalize the parts. One problem I recently ran into was the X carriage was printed and warped due to wheel pressure, I just cnc milled a replacement out of MDF which works great so far.
Jim jim jim! Nice work
@Wayne_Friedt , sorry about sounding so curt, was texting the reply before a movie was about to start, shame on me for being “that guy”. Anyhow, did not intend to sound like a DB. I’ve done a lot of searching for decent core xy designs in an attempt to build, but there appears to be no documented designs, until @Eclsnowman , and @Wolfmanjm apparently.
And Jim, most excellent instructions on your page, wow. Glad you linked this as Google apparently does not find it
@Eric_Moy No no its not a problem. Mt last statement looks kinda smart assish but it really was not. I had looked at that Uconduit bot when i was first getting into printers so it was a while back.
@Brigham_Valdez but that’s a hbot right, not corexy? Not sure what makes it a better proposition than @Wolfmanjm 's design, particularly as Jim has done such a good job of documenting it.
@Paolo_Amboni let me know, i’m curious! (anche in italiano se preferisci)
