Print paused by external trigger

akisjon

Hello to all

a week ago I decided to put on a filament sensor with a switch at the E1 and the next line M581 E1 T1 S1 C0 to config.g . For a week it was working normally now its starting to pause at random times with this message <Print paused by external trigger>.I have change E1 to E0 same problems, i have to change switch I thought but the same result, what can happen and do that?
thank you in advance !

As you are using S1 in the M581 command, I presume the switch is closed when filament is present. Three likely possibilities;

Bad switch contact
Bad crimp connection at one end of the cable.
If the switch wires run right next to a stepper motor cable over a substantial distance, and they are not twisted pair, then it's possible that they are picking up inductive interference from the stepper motor current.

so after a lot of tests I did not do anything , I put a third switch and I check the cable pins with polymer even the same problems.
I changed the M581 to M591 D0 P1 C3 S1 but same , I crazy I do not know what else to do.
forgot to say i have try both of extruder endstop E0, E1.

See #3 in my previous reply then. BTW filament monitor are normally configured using M591 in recent firmware versions, instead of using M281 triggers.
