General Assembly Talk / Re: Has anyone replaced the extruders on their Bukobot?
« Last post by Rocko on June 17, 2017, 03:35:04 PM »
onovanday,

It's been a few months since your post, did you ever move forward on your upgrade?

I'm also frustrated with my machine.  I seem to be spending more time calibrating instead of printing.  I've been considering doing a full upgrade/mod  (hot end, extruder, build platform, auto bed leveling). But by that point it's almost an entirely new machine.  Maybe I should just start from scratch.  In either case, this looks like an awesome extruder with the E3D hot end: https://www.matterhackers.com/store/printer-accessories/e3d-titan-aero-extruder-12v-300mm

The configuration looks like a good match for our x-carriage (horizontal rather than a vertical Prusa-type platform).

It sounds to me like you're putting out a little too much plastic, causing it to mound up around the nozzle so that it bumps into it later. You should check your filament diameter, and you may need to adjust your flow rate.

Thanks for the files Benmlee I'm trying them out now.

I'm frustrated with my machine and I don't like the way the filament is fed into the extruders, so I am looking to swap mine out.

Looking for any recommendation if you've done this.

Thanks!

Hardware & Mechanics / Re: Bukobot duo nozzle height alignment

I sometimes get the ghosting, but it usually goes away after a few layers. 
Have you measured the filament diameter along several points with good calipers and entered that in to slicer?  You might me putting out too much material. 
Try dropping your bed just a bit to give the first layer more room.

Hope this helps,

2nd Extruder is RUINING my prints!

No matter how closely I have the two extruders aligned vertically, the 2nd still scrapes across the existing material either creating "ghosts" of the nearby geometry in the currently printing area, or just piain pulling the print up off the bed.

The 2nd head either ruins the part finish, or ruins the entire print. 

Is anyone getting dual extruders to prints smoothly????

Bukito General Assembly / Re: Y motor moves only one time after reboot
« Last post by whosawhatsis on April 16, 2014, 09:46:08 PM »
So after the Y axis "takes one command", does it move the full distance requested, then refuse to move again? Does it make a difference if the first command is a (positive) jog command (like G1 Y100) or a home command (G28 Y0)? Is the motor locked after the move, or does it move freely?

I have been working a lot with Cura recently as well, and I'm planning to release official Cura profiles for the Bukobot and Bukito in the near future.

We originally had open access to the wiki, but the volume of spam attempts was overwhelming and we had to lock it down. As is explained on the front page (now kind of hidden between things): If you would like to register to contribute to these pages, you will now need to email us at wiki[at]bukobot.com with a USERNAME, Your Real Name and Email. You will then get a return email with a random password to login. Sorry to have to do this, but we've had many spam bots and will keep this until we figure out a better solution. Thanks.
