Help with CNC 3018 from Banggood

Thank you for your reply.

Yes, there is a de-bounce setting and I have it at $26=250 which is the maximum..... it seems I can go. I tried various settings, as suggested by the pocket GRBL guide, but still nothing.

Do I need to change all the wiring to shielded cable? I already changed all the micro switch cable to shielded cable?

Ok well if De-bounce allowed it to work then you are obviously suffering from noise issues so now you need to lower the de-bounce back to Zero, the reason for this is because it slows the switch response time so can be unsafe, and go with a solution like Doddy mentions where you pull the input high or low to stop it floating.

If after this you still get noise issues then there are other methods, like Opto's and Capacitors, etc but won't get into that now because I'm 99% sure fixing the floating input will work.

Good morning JazzCNC,

I just tried the debouched at 0, as soon as I try to carve and start the spindle, I get an alarm. As I said to Doddy, I already tried the capacitors and that did not work.
