+# Creality Ender 3 Pro
+### BTT SKR Mini E3 V2.0, direct drive, and BL-Touch - Raspberry Pi 4 running Klipper & Fluidd
+
+I'm collecting information here to track progress on setting up an Ender 3 Pro that I pulled out of the trash. The previous owner had already upgraded the motherboard and completed a changeover to direct drive. The Z-axis was initially bizarrely overtightened, causing MAJOR skipping issues that squished all the prints about 30%.
+
+After properly torquing the eccenctric nuts on the Z-axis and other belts as well as lubing everything, it printed okay! However, it had Merlin firmware which is poopy so now I'm working on converting it to Klipper. 
+
+Before getting into the printer itself, let's go over how to connect to the Pi, which is running the whole show.

+This machine is currently flashed with a Debian-based OS called MainsailOS - however, I do not like Mainsail so it has been gutted and replaced with Fluidd for the web interface. 
+
+## Software
+
+### Connecting to WiFi
+On the <code>/boot/</code> partition of the SD card, create a plaintext file called <code>wpa_supplicant.conf</code> and use the following template to add the correct information for your WiFi network (this unit is compatible with both  2.4 and 5 GHz networks). Once you have created that file, re-insert the SD card (or reboot if edited in-place) and after about a minute it should appear on your WiFi network. DHCP is currently enabled. 
+
+<pre>
+# Simple configuration for a typical WPA2 network
+
+ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
+update_config=1
+country=US # US Country code
+
+network={
+        scan_ssid=1
+        ssid="<Name of your wireless LAN>"
+        psk="<Password for your wireless LAN>"
+        proto=RSN
+        key_mgmt=WPA-PSK
+        pairwise=CCMP
+        auth_alg=OPEN

+Credentials to SSH into the machine are as follows:
