Counterweight System for Trick Laser Rostock MAX METAL by 626Pilot

Last crawled date: 3 years ago

CAUTION - SAFETY FIRST!!!
You'll need to keep any small children/curious pets away from this counterweight system. Cats are especially problematic, as they may swat at the weights or try to chew the fishing line! If the line breaks, which is a possibility you must keep in mind, the weight will immediately drop, and may cause permanent injury or even death. Please keep this in mind while deciding whether or not this system is safe enough to use in your environment. If you can't keep potentially curious/destructive parties away from the printer, you might want to consider moving it!

INTENDED USES
This is intended for use with my magnetic arm drivetrain system and triple flying extruder platform, which have not yet been released. This section will be updated when they are.
In the mean time, if you happen to have your own flying extruder system, effector-mounted extruders, or anything else requiring that you take significant weight off the carriages, you can use this system to do so.
.
PARTS YOU'LL NEED
You'll need these V-groove bearings, these 500-gram weights (or whatever is suitable for your application if you're not building my flying extruder system), and some of this 50-pound braided fishing line. You'll also need M3 screws, 15mm or longer. You may want to use nylon locknuts to secure them in place. In that case, get screws that are long enough to accommodate the locknuts.
Parts are fixed to the frame using Unbrako #10-32 x 1/2 low-head caphead screws and 80/20 Inc T-Slot HW 10 Series 10-32 Roll-In T-Nut w/Ball Spring #3922 N.
.
PRINTING
This is all supposed to be printed as a single piece, and will definitely require support. There are three separate STLs, so if your printer can do multi-extrusion, you can have the base and arms in different colors. If your printer only does single extrusion, it's okay. In either case, you'll need to figure out how to do multi-STL prints with your slicer if you don't already know.
Use at least 3 outside loops, and at least 20% infill.
.
FISHING LINE ROUTING
The fishing line should descend from the back of the inner V-groove bearing, and it should clear the endstop mount and anything else. The fishing line MUST NOT touch ANYTHING on its way down to the carriage. If it does, the line may fray and break! In fact, it may fray even if that's not the case. It hasn't on my printer, but I can't promise it won't on anyone else's.
