Hello. I wanted to add a limit switch to my MKS DLC32 v2.1 card to use it in lightburn. But no matter how much I tried, I couldn’t use the black switch in the picture. The laser head still continued to work. (Shouldn’t it stop when I hold down the switch?) Should I make a setting in the DLC32 parameters or in lightburn? Or should I use the red switch. (I noticed that the cables got very hot while testing the black switch. So I didn’t want to test the switch without being sure anymore)
Some info on limit switches:
…and yes, you have to enable the limit switches in the MKS DLC32 config. By default they are disabled.

If the cables got hot, you created a short. You can use them, if you wired them correctly. Usually, You connect between signal and ground. Ignore VCC line. See some additional documentation here:
