hi bro, you can change the L18050 printer with XP600 basic head to DTF or UV roll to roll. Add a stepper motor to drive the shaft and move the encoder to the right side to control the pump, use bracket encoder.
If you have experience using Arduino, you bypass the PE, PW, and ASF sensors, so that the printer can print on transparent media such as PET film and PET DTV, and the printer can adjust the length of the print area.
And you can also control the pump for manual cleaning or clean the pump manually using a button.
If you are interested, you can contact me on Whatsapp wa.me/6285695407954
