Genmitsu 6PCS Micro Limit Switches with 1M 3 Pin Cable for 3018-PROVer/3018-MX3/3018-PROVer Mach3

Good

About time \i bought some limit switches to stop that awful crunching sound when it trys to overun.

It's a bit of a cheek knocking a star off because these didn't fit directly onto my machine since it's not a Gemritsu, but that's life. I had to 3D print some simple brackets to fit these, and cut the three way sockets off one end of the cables and fit two ways instead. On a good note, the six cables supplied were so long each one made two of the cables I needed, so I have three spare. Once fitted the machine does a 'zeroing' operation on command, so if the machine hangs part way through a job it can easily be restarted with the same reference position. Only snag is it sets the Z origin at the bottom of the travel - this is logical, but since it does Z first means it will smash the tool into the bed unless you manually jog the X and Y so the tool is off the bed before starting a Zero or Home operation. I found a work around was to perform a Zero, then jog the tool up 30mm and close the software, once reopened the Home position is set 30mm above the bed. A minor faff but it works.

Got these for my cnc machine they are good quality and easy to install

Bought these for a Misco 3018 Pro CNC (Amazon) and thought they will fit but the mounting holes are aligned with the switch side and not the connector. The holes to accept the pins are not aligned so you can't fit them. I will keep them for another project and will make my own custom ones.

after fitting and using I found that three of them had the levers come off. I then had to use the microswitches only without the levers.

Very pleased
