This is an ideal upgraded accessory for 1610 PRO, 1810 PRO, 3018 PRO and 3018 PRO MAX CNC that do not include homing and limit switches. Three switches will be needed for homing and six total will be required if you would like to have both homing and limit functions on all three axis. Most 3018 PRO and similar machines feature 10mm linear rails for X/Y axis and 8mm linear rails for Z. Newer all aluminum 3018 PRO MAX or 3018 MAX type machines feature 12mm linear rails for X/Y axis and 8mm linear rails for Z. Check the diameter of your optical axis linear rail before ordering as there can be great variation among the various vendors of this machine.

Note: Installing homing and limit switches will slightly reduce the overall maximum travel of your machine (Roughly by 12mm per axis for every installed switch – thus a homing and limit switch on the x-axis will reduce total machine travel by ~24mm on the x-axis). While it is common to install a homing and limit switches on all three axis, many 3018 users do not install (or remove) the limit switch on the Z axis as the machine is already somewhat “Z-travel Challenged”.

*we don’t control the manufacturing of the 3018PROVer and MX3 type machines, as such the vendor of these machines may make modifications to product specifications. Compare the product in the photo to the one you’ll be replacing. These switches feature a connector output that is 90 degrees to the switch function. We’ve seen some machines ship with the connector in-line with the switch – so do a bit of research before ordering to be sure you get the right one!
