00:00 Intro 02:09 Prepare the Linux OS (For CB1, optional for PAD7, do it only if you want to install the latest OS) 03:12 Setting up WiFi (For CB1, PAD7 can just use the touchscreen to setup WiFi) 03:43 Setting up WiFi (For Pad7) 04:14 Setting up Multiple instances of Klipper for multiple printers 08:49 Changing hostname 09:35 Adding multiple printers on the web interface (Fluidd) 10:17 Adding multiple printers on the touchscreen (for Pad7) by adding KlipperScreen.conf 11:27 Flash Klipper firmware on printers 12:22 Setting up the printer.cfg and debugging error messages 15:01 Change the name printers on the touchscreen (for Pad7) 15:40 Input shaper calibration (for Pad7) 16:41 Sending print jobs directly from Cura using Moonraker plugin 17:57 Test print 3D benchy(55 mins) using Ender 3 printer profile 18:50 Moving the MicroSD card from the Pad7 to the CB1 and finding the new port on the CB1 20:08 Test print 3D benchy(40 mins) using FFF custom printer profile 20:44 Some upgrades on the Ender 3 Neo 22:38 Conclusions Today, I will show you how to set up multiple instances on Klipper with the BigTreeTech Pad7 or the CB1. The CB1 is a Raspberry Pi replacement board and is combined with the Pi4B adapter to make it work as a Raspberry Pi. Getting something like this costs around $50, and like the Raspberry Pi, you also need to get a USB-C charger and a spare MicoSD card to get started. You can also just plug the CB1 right into the new generation of BigTreeTech motherboards like the Manta series I previously tested. The Pad7 combines the CB1, Pi4B and the heat sink with a touch screen and packs everything in a case; the package also comes with accessories like an accelerometer for input shaper calibration, a 32GB micro SD card with the system OS pre-installed, and a power supply that allows you to use it right out of the box; this Pad7 costs around $130. If you are worried about it being difficult to configure the Pad7 or CB1, I will show you every step in this video, as well as setting up multiple instances.
