  • Our 3D Printer Fleet

    Thanks to a recent donation from kylejdyck we now have at least 5 semi-working 3D printers in the Makerspace.

    Unfortunately most of them require a little TLC, as we've been having problems.
    A concentrated effort to do some repair work on these would have the Makerspace an unprecedented robotic fabrication army to do our maker's bidding.

    If anyone would like to take these on as a project we could really have an awesome set of tools. A good strategy might be to designate certain printers for specialized tasks based on the strength of each printer.

    Here's a quick rundown of where we stand:

    Prusa Mk2S MMU
    • Built into an enclosure that works really well for high temperature prints like ABS
    • Currently experiencing problems with bed adhesion
    • The hot end temperature keeps dropping off when the part cooling fan is running, this needs to be fixed.
    • The MMU (Multi Material) is virtually never used, and is less reliable than a single extruder.
    • We may or may not have enough parts to change back to the single extruder.

    Prusa Mk3
    (Belongs to Vaughn )
    • Currently has a 0.6mm nozzle installed for fast printing
    • Just had a tune up last night with some software upgrades and z-axis adjustments that has it running sweet.

    Delta Go
    • A new donation from Kyle "The Delta Go has the upgraded effector where they added a part cooling fan and new bearing-style rods. I've had a couple issues with some of the plastic pieces assembling the new rods, but I still have a couple parts left that could fix it."

    i3 Clone
    • Also from Kyle "The i3 clone I believe needs a new hotend as it doesn't seem to extrude consistently. I might even have a replacement I could include."
    • Kyle actually dropped off 2 replacement hot ends. These might be a good fix for the Prusa Mk2.

    Aaron's Printer
    • Sounds like this is almost working but there are a few problems in tuning it.
    • Not sure whether Aaron plans to leave this as a shared printer or not?

    Looking for member input here, what do you want to see? Any of these that you'd like to take on as a project?

    Agree on swapping the mk2 to a single extruder - I've had a few failed prints and it seems the filament I'm using is jamming at the spot where the different extruders' filament paths join.

      My intention is to take on the i3

        Hey Dave, how did you make out on the i3? Any updates from your Hack session last monday?
        When its good to go please make some recommendations on software for preparing prints and any other tips and tricks.

      I have been working on/ fighting with that i3 I bolted it down to a piece of plywood to stop it from being floppy, switched out the hot end and tried printing whistles.
      The whistles didn't turn out well, I figured out the plastic isn't coming out fast enough (80.5 instead of 121.9) and the hot end wasn't running hot enough (180 instead of 210).
      Currently I can't figure out how to get the machine to remember the changes I make. I am thinking of learning how to add the gcode to any print to get around that. Ron_Ron may have a memory chip that can be added too.

        Yesterday I tightened the y-axis belt, manually reset the extruder feed to 122 and nozzle to 210 and got a half decent print from it. If you want to use this machine you should manually set those numbers or include them in the gcode

          What program are you using right now to create your g-code for the machine?
          What unit is 122 on the entruder feed? Steps per minute? 210 for the nozzle is temperature I assume, sounds right for PLA.
