The late-arriving shorter 152 mm belt is proving to be annoying. The 156 mm belt is too long, but I want it to work so I can wrap up ("wrap up" hahaha riiight) mechanical design and assembly this weekend:

That spacer is 6 mm thick, so the 152 mm belts wouldn't be short enough anyway. And having less space between the bracket and the plate makes it tougher to tighten the stepper mounting bolts. And I need to mount the modularthings boards anyway, so a bracket redesign is in order. The first go went well enough but required a bit too much clearancing to work:

Ahh CAD assemblies. Some of this was misjudging the stepper overhang, some of it was related to the grub screws on the pulleys, all of it ended up looking like hot garb. A fresh print with minor tweaks looks nice; note updated pressure knob color too, to match the spindle (and avoid matching the X-axis grey knob):

Both modularthings boards mount nicely to the bracket backpack, to which I also added some diagonal support braces that at least look intentional if still a bit janky. And! Note the LED color on the stepper board, which is usually much brighter green: I reflashed the boards to update their names and didn't have any issues, a testament to good firmware design and the loveliness of platformio:

The stepper board lacks a shell, and also runs slightly different firmware, and has a big integrated switchmode power brick hanging off the top, so it will probably stay not-matching. Which is fine. The bigger issue, I suppose, is that Jake uses a slightly different shade of grey PLA for his spacers, but... that is also fine.

More to come shortly; if I can summon the energy I might try to spin motors tonight, or it might wait for some night this week (again, pending energy, of course). I think I have everything I need in place, perhaps short a single ribbon cable connector, but otherwise should be able to do a full test soon soon soooooon!
