Wildly inconsistent first layer while using Octoprint
Been scratching my head at this and wondered if anyone else had experienced it. Loaded up a file on Octoprint and as it drew the first layer I noticed it was extremely squished so I backed off the live z until it looked good. With that z setting saved I stopped the print, cleaned the bed, and restarted using the new live z.
HOWEVER, now instead of being at the new height it still prints very squished and must be adjusted further, over and over again.
So I shut down Octoprint and loaded the file onto the MK3s SD card. First layer came out beautiful and smooth, so I'm kind of at a loss.
Anybody else seeing things similar to this?

Re: Wildly inconsistent first layer while using Octoprint
You need to let the bed fully cool before you start another print. The heat compensation for setting the initial height is a bit off. I've been having this problem since I got the printer in early February, and I'm currently running the 3.2.0-RC2 firmware. Just let it cool and it'll print exactly the same every time.

Ouch, that's gonna be fun while printing ABS. Thanks for the info though.
Re: Wildly inconsistent first layer while using Octoprint
The RC2 firmware has commands to manually calibrate the temperature compensation.
Check out the later pages for info on the process. Should solve any temperature issues without having to wait for the pinda to cool down.
The final release may be coming soon so it might be worth waiting to flash as they're still working out a few bugs.

Thanks for the info! Definitely gonna be waiting for the official release, that's why I'm still on 3.1.3. I do appreciate the info though! I will read through that thread now.
