CNC Router 3018 Pro Limit Switch Upgrade

cults3d

The CNC router from China commonly referred to as 3018 Pro CNC Router is fairly inexpensive and can be upgraded fairly easily. This Thing will help you install limit switches which help prevent damaging the machine by crashing it. This thing is intended to be used with the Pro version which is made of both extruded aluminum and CNC routed plastic parts. The standard version is mostly made of extruded aluminum. While this might work with both, I do not have a standard version to test it with. #3D Printed Parts# Qty 2 - X-Axis Limit Switch Holder V2.STL Qty 2 - Y-Axis Limit Switch Holder V2.STL Qty 8 - T-Nut V2.SLDPRT #Limit Switches# Qty 4 - Limit Switch model: V-153-1C25 Micro Limit Switch Long Straight Hinge Lever Arm SPDT Snap Action https://www.amazon.ca/gp/product/B07DGX5Q1Q/ https://www.digikey.ca/product-detail/en/omron-electronics-inc-emc-div/V-153-1C25/Z4613-ND/1829013 You can search AliExpress for "V-153-1C25" just make sure you get one with a long arm as specified by the model number.
