if you send me some pictures of installing i will include them here, happy tinkering!

@mtran1

So I have everything installed but the y limit switch doesn't touch anything. Is that normal?

The designer has replied

@Driest

the switch touches the magnetic orange plastic panel.

Its probably a dumb question but, the color of the JST connector wires dont matter does it? should i buy pre made connector/wire combo or buy the 3 pin connectors and thread the wire and crimp myself, because i cant find one with only red and white wires. Also where on the board do they plug in at?

@Hopper2009

Hi! Colors do not matter, just be careful not to swap them. I bougth a pack of 15 cables and JST conector, then cut the one cable I wont be using, then solder another cable to extend de conections from the moderboard to the switches. Good luck and happy printing!

@tielemans.jorim

Nice one, thanks! Did you consider using four limit switches?

The designer has replied

@Driest

i do not think 4 limit switches are needed, since you can set soft limits in lightburn, which will keep your machine from hitting the other side after homing

@Hopper2009

Worked perfectly. Also lightburn give me "alarm 8" , so I changed Homing debounce $26 to 500 and Homing Pull-off $27 to 6,000
