LDO Voron 0.2 Build - Software Install & Startup Checks

I'm building the smallest Voron 3D printer with the goal of tuning it to print with the highest possible precision. In this episode we set up the raspberry pi and klipper firmware, then run through a whole slew of startup checks to make sure everything is wired correctly and ready to print.

Hey Mark,
I wanted to thank you for this video series. Ive never owned a 3D printer prior to ordering this V0.2 kit. Ive also never built anything even remotely close to something like this. The last thing I remember building was Legos when I was a child… I also had no experience working with electronics or software either. I’ve been able to complete the build after following along with your videos and I couldn’t be happier with it. This build has taught me so much about 3-D printers. It has been such a rewarding experience for me. Once again, thank you so much for taking the time to do this.

Wow, thanks for the kind words. I count it a privilege to help people learn about this hobby. I hope you can use the new printer to make awesome things!

This series saved my bacon so many times with how-to instructions and links to the instructions that are nearly IMPOSSIBLE to find on LDOs web site.
However, you missed a step on the hot end PID tune. The sentence below the title in the instructions says to set the Part Cooling Fan speed to 25%. It even gives a code to enter. The next line after that is the one copied and pasted that executed the PID tune of the hot end. It may be slightly off. I don't know if this tune determines the reaction time of the heaters or what. For this reason, I built my enclosure first because if it needed those fans at a specific speed, it was sensitive to ambient temperature. In that case, it needed to be done in the environment I would be using it in. I did my tune with the cabinet assembled, top hat and the door closed. The room is 68F. I don't want this to affect something in the hundreds of degrees.
Great series. A must for Voron V0.2(S-1), V0.2(S-1)A+, and the identical V0.2R1.

You're right! I did skip turning on the fan when I ran the PID tune during that initial setup process. Like you, I ran it again after building the enclosure and I did start the fan that time.

Awesome to see all the mechanical components moving around with the electronics all configured now! When I upgraded my Ender3 Pro to Klipper I didn't use KIAUH. I used a prebuilt Mainsail image from the Pi Imager tool. After watching this I wish I did use KIAUH it seems very straightforward and simple. I'm constantly getting errors about the Moonraker config and at this point I think it's an issue with the prebuilt Mainsail image although I haven't explored it too much.
I'm excited to see this one printing. If you do modify it I'd be curious to see what mods you do. I know a lot of people are doing performance mods to print fast, and that's cool. I know your goal isn't necessarily fast, but precision and I'd be very curious to see what config and physical mods you do to achieve that goal.
Thanks for sharing this build!
