3D printer update: our xy stepper motor assemblies are fully put together and mounted! (pretty sure there's still an adjustment step later, some of the parts seem set up for that)

the instructions used very strong words to advise applying thread lock to the little bitty set screws that hold the spindly things to the motors, but alas, the kit didn't come with any and we don't have any in stock because we've never used it before. it's on the list of things to acquire and do later, like the oil.

that was kind of intense. like, they're just little fiddly bits, but... we've had our night meds, which affects our dyspraxia, and we kept dropping pieces. at one point we were briefly trapped on the floor after retrieving a part, but we are no longer there, so that's nice.

we have a nice wood floor with some give to it, we like it a lot, but it is nowhere near as pleasant as our fancy foam mattress

desire is the origin of suffering and all that, and we don't really have much attachment to material things, surviving a fire taught us that... but we have money so we might as well use it on things that make our life substantially more pleasant, such as floors and beds

but ow. do not try to exchange the one for the other. ow.

anyway! stepper motor assemblies! they are super cool!
although we had already admired the coolness of the individual pieces weeks ago, along with the coolness of the strategy of using little shims to adjust the positions of things on spindles rather than paying for fancy custom-machined parts

stepper motors are honestly just a joy to hold in our hands though. such precise machining.

much like when we fitted the linear rails onto the extrusions last-week-ish, there's a little custom printed part that acts as a guide to position the little spindly things on the little spindles. it was very neat.

we keep being blown away by the ABS printed parts, too. we hope the printer itself can do things even a fraction of this robust. they really feel injection-molded in the ways that matter, the rigidity and also the give and all that.

(they're not injection molded, if they were the factory wouldn't have made us wait a few extra days to get them in the colors we wanted lol)

(and also we can see telltale indicators)

it's really amazing to think that it can print, not just cheap toys, but actual precise parts. fingers crossed! our understanding is there's a high skill cap if you want to get it to make the best stuff

we generally do well with things that have high skill caps, we're sure it'll be fun :3

wow though. so many tiny shims and nuts dropped on the floor. so much time down there with a flashlight. in the end, we didn't lose any... yay

oh yeah, and we're looking forward to putting the belt (belts?) for the xy thing on soon. then maybe we'll understand how it works. it's a very clever system where the motors pull diagonally but they work together to produce X or Y movement. apparently this is a widely used thing, with a name we don't remember... it makes sense to us in terms of vector math, but the actual belt routing will probably only make sense when we play with it

oh, right, right, and we are much better and faster at the heat-set insert insertion compared to the previous ones we did a while back. so that's nice
