Magnetic filament sensor Is there a way to disable mid-print?

[Steve Lynch]

I'm 97% into an almost 40 hour print of about 150 small parts on My 500 x 500 corexy. The filament sensor never allows a print to make it completely through without stopping at least 2 or 3 times. This particular print is using ironing (which I inadvertently sliced the file with) and each part is erroring 6-7 times before advancing to the next. I've literally been sitting here for 5 hours hitting resume, and I'm about to go batty!

Is there a way to disable this thing so the print can finish on it's own?

Also, I've worked on this thing for over a year, and I've never gotten it to survive an entire print. I've tried every suggestion you guys had.

Before I simply put an open / close switch in, is there a way to set this so that it basically will be bulletproof, and only tell me when filament runs out? That's all I care about. Is there filament, or not?

what settings would I need to change to ensure that I can finish a print without multiple interventions?

Thanks so much!

@steve-lynch, send M591 D# S0 to disable the sensor, where # is the extruder number.

@dc42 Thanks man!

@steve-lynch Sorry if this is going over old ground, but what does your sensor currently report? Send M591 D# when it is running.

Ironing, I think, extrudes tiny amounts of filament, so maybe there is some movement between the magnetic sensor and the extruder, so maybe these small movements are not being picked up?
