Re: Cracks in print and clicking extruder motor

That definitely sounds like clogging. I've also experienced that with models that have a lot of retraction tend to clog the nozzle more. My solution was to run at a higher temperature after cleaning the nozzle really well (burning out the nozzle with a blow torch, dragging a wire through a few times...

Re: Cracks in print and clicking extruder motor

The extruder clicking sounds like either a clog in the nozzle, or the nozzle's heater isn't up to temperature. The extruder isn't able to push the filament through the nozzle, which causes the clicking. I have encountered the latter a lot with my printer. It is usually a faulty cable (it has happene...

Re: Stepper Driver Comparison for upgrade

I just installed the SSS drivers on my 2014 Series1 beta machine (B0049).

Re: Stepper Driver Comparison for upgrade

Elijah, What jumper config changes are needed? I just received the new drivers for my 2014 Series 1 (B0049). I tried putting them in, but the z-axis was moving the opposite direction from what it was and made an awful noise when doing so. Installing the old drivers made the printer proceed as was no...

Tomographic Data

I just thought this was neat that it can be done using the Series 1, so I thought I'd share it. I finally got around to printing some of the data from my thesis. It is the structure that a conductive polymer (P3HT) takes on in a plastic solar cell. I think it makes a rather nice piece of scientific ...

Re: Tracking down vibrations

Reducing the current did not fix my problem. I reduced it enough to cause major skipping and the thing was still incredibly loud . I'm only printing at 60mm/s. I'm not sure what to try next.

Re: Tracking down vibrations

I remember a while back there was mention of getting upgraded drivers for the motors. Caleb, do you think this could help? I'm not sure what is limiting the current to the motors, the drivers? or the RUMBA board? both? I have a 24V machine, but I'll give reducing the current a shot. I had to turn it...

Re: Tracking down vibrations

Ok, so after more futzing with it, I'm pretty sure it is the linear bearing on the x-axis vibrating. But, that seems strange to me. I've also noticed that it doesn't vibrate when it is moving, only when moving and extruding. This would suggest the extruder motor, but I've checked it and damped it an...

Tracking down vibrations

I was wondering if anyone else has a very loud printer because of vibrations during movement. This has always been a problem for my printer at speeds above about 50mm/s, but for the life of me I can't find where the vibrations are coming from. It is the loudest when doing long lines in a diagonal di...

Re: BuildTak is awesome

I think you might need to get the nozzle closer to the bed. I know if my nozzle isn't close enough to the bed, I get terrible adhesion, regardless of the substrate. I have my nozzle touching the bed, and dang near touching when the height is set to 0.2mm. You could give that a try.
