Hey guy it’s me again, machine was working beautifully lately, today I left it drawing and suddenly noticed z axis dropped, it seems the top blue part is not attached rwell or so, it can still run up and down by the motor.
But, when I put Sligh pressure even from the bottom, the whole z axis moves up so something got loose for sure.
I think I figure it out, it’s connected well to the rod going down, so the one with a spiral texture on it. But it got disconnected from the rod going out of the motor(smooth looking rod)
Either a little tighter on the upper screw closest to the stepper, or if you think you might break it, a little superglue. If the coupler ever breaks the plastic can be scraped off the stepper shaft without hurting it. Also, once you have it back in place, run the black plate that’s under it right up against it(go up). That way the bearing takes the weight, not just a piece of hanging plastic.
It looks like you might have tried to lube all your bearings, for the most part you should consider them sealed and not able to be lubed. Some lubes do not interact well with PLA plastic, your parts could start to degrade. The coupler issue could be from that. All that lube is just going to make milling debris stick to your machine.
its basically using 4 different pens, normal 2 cent pens from the office shop, and use them to make a full color drawing like that one.
about the lube, as those drawings take ages, at night I heared horrible squeaking noise coming from the Z axis, it was 2 AM and i wasnt very careful with my aiming. the noise did stop at least and i cleand up the mess later on.
And Jeffeb3, I’m not really selling organized yet, just sold few pieces and some were used as an album cover by an Irish band
At the moment busy trying ti apply for art funding so I can push it all a bit further and make a more serious series of drswing or even paintings if I can solve some - brush going to dip in paint every few strokes - problems
