there's a lot of work that can and should be done on this printer, but it's all gonna be limited by the fact I can't stand up for more than 5 minutes

well, there's something going on with the z-axis, but it printed more or less.

I've also got to switch to a different power supply for the pi that's running octoprint, and upgrade the pi to a new OS (which requires backing up and restoring existing octopi settings) because my python is EOL.

so it's working, but I'm still sighing a lot

anyway I loaded new filament and I'm printing a chep cube again!

wow it's terrible

okay I printed a CE5P calicat after attempting to fix the z-offset issue. It still is horrible.

possibly this is mostly a temperature issue: I'm using the stock temperatures but I think I upgraded this to an all-metal hotend that needs to run higher?

include the photo, foone

reprinted with higher temp. it's better, but still bad.

so probably there's another issue. I remember I did a lot of rebuilding of the hot end in the final days of using this before, so who knows what's clogged in there?

I printed on a raft because the z-offset is still fuckt

a higher temp (220°C) and 110% flow rate seems to be working well enough.

had to dig out my flir phone to take pictures for silly cellphone reasons.

Anyway, this is the 220°C 110% flow calicat. It looks way better, right?

So I foolishly started a 9-hour print and yeah it's still shit.

also octoprint is yelling that my pi is undervolting. I'm specifically using a dedicated 5v 2.5A wall-wart, how is it STILL undervolting? ugh.

I need to throw away and replace every part of this setup and I don't have the time, money, energy, or space to do that

Thanks to everyone who has given suggestions for how to fix this. Unfortunately most of them require me standing up for longer than I can manage, so I've mainly just fiddled with settings (since I can do that from my bed).

but when I can, I'll be:
* calibrating the extruder
* trying to clear clogs in the hot-end
* calibrating the z-axis offset (which is a multistep nightmare in this setup)

I need to upgrade the octopi install so I might switch to a newer pi. I have one somewhere, it's just probably up in my office where I can't really get to it (stairs)

installed a USB power blocker to try and fix the undervolting. it didn't work.

So I'm gonna have to find another power supply for that

I'm gonna try cold pulling next because that's easier than getting to the extruder

okay I tried switching to a different USB power supply (5v 2A) with thicker usb cables: No difference, still undervolting.

I also cold-pulled the hot end a few times, to see if that'll help.

the extruder is still difficult to reach

printing another calicat to see if that changed anything
