ah, good find. Though it states "As this is only called for homing moves and with very low speeds, we assume that we don't need acceleration or deceleration phases." in the function called. So I believe this will lower the speed for the second pass, but it will still be a hard stop for the first. I might be able to modify it myself from here though. But a proper implementation would be preferable.

So... Mechanical dampening seems a bit overkill though. How hard would it be to just have the motor deaccelerate instead of full stop when doing first pass? I guess that would be enough for me at least

I would like to have a second homing switch placed let's say 20mm from the first one. Then you can have the gantry move at high speed til it reach that first switch, then it slows down to normal homing speed the last bit. Would this be possible at all?

You could use optic or magnetic sensors for the first one.

This is what the board look like.

I tried connecting signal and ground and it seems to work fine without changing sensor type in configuration. Maybe it would be more accurate though if I also connect it to +5V?

I'm in progress of installing Duet WiFi in my Wanhao D4S. It comes with a 4 wire thermistor for the heated bed. How should I install and configure this?
