All axis stop moving before hitting switches

Phaedrux

Can you go through these steps to test endstop and motors before homing?

@Gabell20 when I imagine that your G1 H2 runs ok, but G1 H1 stops after a few mm, and you use NC endstop, is it possible that the movement triggers the endstop, by the movement eg? If the G1 H1 stops, does the DWC show the endstop triggered?

@Phaedrux That is helpful, but i followed along and the problem persists.

@JoergS5 that could be it, I noticed that sometimes under acceleration thy show up triggered, I wonder if I can makes the axes accelerate slower but only during homing.

You certainly can. Just add a new acceleration command at the start of the homing file and then change it back to the previous value at the end.

@Gabell20 ~~as a first test you can set the F values low while homing.~~
Phaedrux you were faster and had the better answer

@Phaedrux @JoergS5 thank you i will try that now. EDIT: that did not work, now I have the same problem but slower lol, I should just purchase new switches

Phaedrux

What exactly are the switches?

Gabell20

@Phaedrux I don't know, they are just no name switches that came on the machine. i am going to try putting ferrules around them.

Gabell20

So as it turns out, the wires from the switches were picking up some noise and causing the input to go high. I solved this by using shielded wire for my limit switches and now the machine homes just fine. Thank you @Phaedrux @JoergS5 @fcwilt for your responses.

Glad you got it figured out.
