Please take care not to pull too hard on the flex cable to avoid breaking it","When printing with multi-color filaments, the PCB circuit board recognises when consumables are being fed in and out and transmits the information to AMSlite for switching between consumables, as well as detecting if there is a blockage and responding with information to the printer","Easy to Install, just remove the back cover of the print tool-head, remove the extrusion mainboard, dismantle the buffer, detach the Hall board sensor from the buffer, and replace original.
