This selector switch lets you choose from 2 rotaries connected to your XTOOL D1 laser so you can keep the old rotary connected for the rollers and connect the RA2 Pro for the Chuck. Has 4 connectors, 2 for rotary accessories, 1 for the “Y” axis and 1 to connect to the mother board where the “Y” access was connected.
IMPORTANT: All switches include the ‘Y” stepper cable so if you order now for your Original D1 and upgrade to the D1 Pro later, the switch will be compatible.
