Bukito General Assembly / Re: Y motor moves only one time after reboot
« Last post by leo on April 10, 2014, 05:29:22 AM »
Are you getting a "commads waiting" message, or any errors in the console? Does it take move commands for other axes before/after that?
No. There are no errors and "commands waiting". I use Flight Check manual and manual control. Y-motor takes only one command independently of other commands.
I can move other motors before and after Y-motor.

Is it possible that short current brokes a piece of Bukito's "brain"?

Hardware & Mechanics / Dual Extruder Problem
« Last post by Lwanmtr on April 10, 2014, 04:14:05 AM »
I have a big problem on my Duo.  Extruder 2 is slightly lower than extruder 1.
Using the paper method when i level, #2 grabs the paper before #1..
If i level to extruder 2, then extruder 1 is too far and the filament just gets all squiggly.

This is resulting in #2 dragging accross my prints, pulling them off the bed.  Until now I hadnt noticed it much, but have a larger build and
its killing it every time.

Is there any way to adjust the hot tip?

And yes, I've made sure the x rail is level with the frame, and double and tripple checked the bed leveling.

Thanks.

I have a bukobot Duo from the kickstarter campaign.
I've never gotten it to print well.
The provided settings in the wiki have been tried and they do not give a great print.

I'm using:
Filament: Green ABS IC3D,
Temp: 230C
Bed: 110C

The surfaces are printing kind of unevenly (I've tightened up the X/Y "belts")
The corners are blobby like it is over extruding or dwelling on the corners for too long.

The extruded filament is measuring at .019" or .48mm.

My settings screenshot are attached.  Thank you!

I guess ill need to get one of those caliper thingies to measure filaments each time...hehe

Yeah, I found the speed in repitier, trying different speeds to get the right speed, at least for the current filament.

I was trying to slice at .05 and slic3r kept bombing on memory
Slice3r is pretty fast (if you turn off 'avoid crossing perimiters'..otherwise on larger builds it takes a couple hours.

I just downloaded Cura and am looking at it.  Looks good..if you can get some profiles, that would be cool.

Bukito General Assembly / Re: Extruder motor not working

Ah. We've seen that once or twice since shipping the first batch, and I've since built a test rig so that we can check all of those cables before sending them out in future batches.

There is a flow rate multiplier slider in Repetier Host for adjusting while printing, or you can use the extrusion multiplier in Slic3r's filament settings, though if everything else is working properly and you have the correct diameter measurement for your filament in Slic3r, these should not be necessary unless you are using a filament like TPE, which compresses into the drive gear enough to reduce the drive gear's effective diameter while pushing it.
