SLA 3D Printer Project Log 12: Dropping the Hammer on lack of construction

You know that feeling when you've finally been liberated to make real progress on something?  In a sea of drudgery and busy-bodying in the real world, this is a shot of Dopamine straight to the brain.  This is even more so when you've been procrastinating something for so long that spiders the size of your big toe have set up ambush positions in your cooking utensils (as happened to me when I cleared out my shed; yes, my spine is Petri Jelly, no need to remind me...  *sigh*).

Nails, the classic solution for design ineptitude - that or excessive amounts of glue and filler!

The rush of finally taking action is, as we all know, the best time to find out we've been imbeciles – as I found out when I discovered my top vent had no tabs for locating the parts together!  I had basically expected the builder to be able to glue these together against gravity no matter which way up the join was being made.  Rest assured this will be fixed in the final 1.0 release, but for now, we can get busy with a Pin Vice (Check out the review here!).

If you think this is laborious, try correcting a hammer drill gone haywire...

As I examined the Z carriage to which the Build Bed is mounted to, I couldn't help but notice that there was a slight warp, a horrifying scenario for a part absolutely dependent on being straight and true!  At risk of making the Z carriage too heavy for the Stepper Motors, I knocked together a barn-door solution on a whim...  Unprofessionalism?  What is this, the Intel FABs?

Spare Extrusions fixed in place with Stud-Locked Nuts and Bolts; a nice solution, though I'd be lying if I said I wasn't concerned for strain on the Z motors.

Among the bits that I bought in a project-buying frenzy were some black, chunky tapes with a faint magnetic field.  These are for mounting the UV-Reactive Acrylic Window Panels.  TBH I'm a little worried about their powers of retention given that most ferrous things are barely attracted to them, but at least my Hard Disks are safe :)

Pro-Tip for those doing this:  Dampen the plywood surface where the ends of the tape meet, apply cyano, then affix.  Safeguard against peeling ;)

One final note is how we can expect the panels to be mounted; I've found some Slim T-Nuts for the extrusions that don't need to be slid in before the panel is aligned, so I can mount the panels after the frame is built – you can't imagine how much rage this will save!  On the downside, I've missed out on the chance to become the next Francis...

This thing locks against the extrusion when tightened, so no worries about it spinning in situ.

Locking in action, shouldn't too hard to remove them again.

Stay Productive...
