Silhouette Alta Klipper/Fan/Display Upgrade

thingiverse

Recently I got an old Silhouette Alta from a friend who was rather disappointed by it. Being into 3D printing for several years now I really have to say that the Silhouette Alta sucks in many ways. However, you can make a pretty decent PLA printer out of it by uploading Klipper firmware and attach a fan. It can now print PLA autonomously with more than 80mm/s with pretty decent quality. If you like, then tips/donations are very welcome :-) 1. Install fluiddpi to a Raspberry Pi as described here https://docs.fluidd.xyz/installation/fluiddpi 2. SSH to fluiddpi and burn Arduino bootloader to Silhouette Alta board using an usbasp programmer (see pinout diagram for wiring) wget 'https://github.com/arduino/Arduino/raw/1.8.5/hardware/arduino/avr/bootloaders/stk500v2/stk500boot_v2_mega2560.hex' avrdude -cusbasp -patmega2560 -P/dev/ttyACM0 -b115200 -U flash:w:stk500boot_v2_mega2560.hex 3. Connect printer to Raspberrry via USB. Then build and upload klipper firmware cd klipper make clean make menuconfig (choose atmega2560, 16MHz, UART0, 250000 baud) make sudo service klipper stop make flash FLASH_DEVICE=/dev/serial/by-id/usb-FTDI_FT232R_USB_UART_A907V534-if00-port0 (adjust to your id) sudo service klipper start 4. Access http://fluiddpi.local, navigate to config file manager, edit printer.cfg and paste contents sample configuration 5. Optional: attach ssd1306 OLED display, encoder/button (see pinout diagram for wiring) 6. Optional: attach 12V, 40mm fan (see pinout diagram for wiring, see printable fan mount) 7. Optional: print and attache filament spool mount on top (https://www.thingiverse.com/thing:4886291) 8. Perform delta calibration (https://www.klipper3d.org/Delta_Calibrate.html) and enjoy a now half decent 3D printer :-) If you like, then tips/donations are very welcome :-)
