Today’s project day, so I got a early, for a day off, start. First and foremost, I’m posting this on my computer, rather than my phone and this editor is balls. The bad version of that word. I use it both ways, so I should clarify. The web version of this editor sucks so hard. Soon I’ll move away from this particular format, so I guess its cool for a day.
Step one, clear the table, moving hot things and clutter are bad. Good enough.
I re-attached the bed heater. It won’t hurt, but it’ll be good to run it like it’s live.
It’s currently out of level, but not enough that I’m starting off concerned.
I had to raise the z-axis to get at the board with the right angle. When I moved up the z-axis I saw that the screws on the far motor were all sorts of loose. Those have been tightened. While manually move the z-axis up and down, I’ve taken the opportunity o fire up the bed heater. I’d really like to get a crap print off of there without too much work.
I just did some crappy masking tape flags and am running the printer up and down a it. in straight up- only movement, everything seems fine. Next I’ll send it down bu… right. I just lost steps. Th flags are still aligned, so it’s not happening at the coupler. That’s good, because I never got around to ordering couplers. Also, how the heck is coupler not in this dictionary. Using a level, it looks like the far side is the one that went higher? That surprises me because it’s the near one that seems to run smoother over-all. Watching it, and it totally was the near one, right about the same height as last time. Lets drop it and raise it a few more times. Going down to zero, seems to not lose steps on either end, and going up to 80mm seems fine as well. I’v started marking the rods with marks for where they’re at.
I’ve now adjusted the feed and acceleration rates on the printer down in general. Yes’ll I’ll lose some speed, but that’s okay with me. Currently it’s the homing speed that’s causing me issues. Where the hell did I change that and why?
Right. I’m just going to do the firmware.

Well that was a bust. Everything kinda looked good to go, start printing, and boom. I didn’t manage to do the firmware either. I did get a plan of action though.
I’m thinking the issue is that I have my lead screws a little low. This needs they’re not hitting the holes they go into at the top of the other. Since they’re not connecting to anything on the top, and the lead screws and accompanying rods are in a line, I think that the entire assembly is twisting. Add in my never leveling anything originally, and the shimmying of the table when printing, and we’re looking at a bunch of issues. Do step one will be building a platform for it to stay level and stable. Then I’ll fix the lead screws height. I don’t actually want to do that, because I think I’ll have to drill the set screws out on at least one. Not my idea of fun, but I kinda knew I’d have to do this.
I should also did into that while firmware thing.
Now, not to get too crazy, but I do kinda want to say to hell with it, to it all apart and build something from the parts. Of course, swap out everything I think it’s complete shit. I’m thinking the power supply, main board and drivers would be first against the wall.
