Some progress tonight
Oct. 18th, 2011 09:56 pmTonight I installed one of my XLR power jack mounting plates on the MakerGear Prusa printer, wired that to the electronics (I used RAMPS 1.2 style wiring even though I have a 1.3 board, it was just more convenient).
I then took my power supply out to the garage and spent a LONG time with a nibbler enlarging the two fan holes to a full 55mm diameter (I don't have a chassis punch that large, and chassis punches are EXPENSIVE - the only reason I have any are that I inherited them from my father-in-law) and also enlarging the hole for the power jack.
I put the male end onto the 10' power cord and buttoned the whole thing up. I didn't seal up the power supply because A) the fan is hitting the chassis so I need to deal with that (probably I will just put some washers in there) and I'm currently printing a 2nd fan grille to cover the open exhaust port.
My fan grille object on Thingiverse is moderatly successful; it was a featured object the day after I posted it, and it has been incorporated in two other projects that I know of. The knobs appear to be getting used as well. I sort of wonder if people are using the microphone stand mount - it's been downloaded a few times so I imagine it is but nobody's posted a photo.
I also did a little Dremel work on the extruder body I printed yesterday (I had a few values slightly off - the perlis of working with non-standardized (AKA CHEAP) SAE hardware on a project designed primarily for a non-US (metric) market). I found that the new hobbed bolt is not only a LOT smoother, it also has a monstrous grip. I do have to recalibrate my firmware for the new bolt diameter, but that's a project for another day. I should be able to resume printing on the new printer very soon now. Hopefully these extruder improvements will bring it up to snuff.
