Monoprice Delta Mini V2 driver fix

## ssh into rpi box. username: pi , password: raspberry
## don't turn on printer, don't have it connected by USB to RPi when performing these commands
## makes sure the apt install will work
sudo apt update
sudo apt full-upgrade -y
## installs headers and the needed dkms tool
sudo apt install dkms raspberrypi-kernel-headers
## download and unzip driver (-j stops it from adding another subdirectory) to the right place
curl -o /tmp/ch341ser_linux.zip http://www.weedo3dprinter.com/lib/exe/fetch.php/x40/ch341ser_linux.zip?fbclid=IwAR29OQyC4fsI5cj1hY2zRxlEQiDTuF-xUl6UaXYzLtzZzaKid4kFbDWjEYg

sudo unzip -j /tmp/ch341ser_linux.zip -d /usr/src/ch34x-1.3
## added option for available potentially "fixed" driver from juliagoda github (not default, must remove # to run)
# sudo curl -o /usr/src/ch34x-1.3/ch34x.c https://raw.githubusercontent.com/juliagoda/CH341SER/master/ch34x.c?fbclid=IwAR0PQvm-k0fWnP4ESNTO180bGNgWJVUzqra02t3SnzJPvINnlTXyyx3Y7Ks

## makes sure the system doesn't use the older drivers already on the system
sudo sh -c 'echo "blacklist ch341" > /etc/modprobe.d/blacklist-ch341.conf'
## creates the needed instructions for the new driver
sudo sh -c '{
echo PACKAGE_NAME=\"ch34x\"
echo PACKAGE_VERSION=\"1.3\"
echo BUILT_MODULE_NAME[0]=\"ch34x\"
echo DEST_MODULE_LOCATION[0]=\"/kernel/drivers/usb/serial\"
echo AUTOINSTALL=\"yes\"
echo REMAKE_INITRD=\"no\"
} > /usr/src/ch34x-1.3/dkms.conf'
## build and install the driver
sudo dkms install -m ch34x -v 1.3
## it should be up and loaded - turn on printer (without it being connected by USB)
## once the printer is booted to the menu, connect USB, and Octoprint should see it.
## if it doesn't work, you may want to reboot to make sure its loading properly over prior drivers (not default, must remove # to run):
# sudo reboot
