Y-Axis fake(?) Crash detections - let's debug

I have built an enclosure and moved all my electronics into a separate bay that is force fan cooled and put heatsinks on the stepper drivers as heat appeared to be the problem. I live in an area where the ambient air temp is frequently over 35C, so everything crammed into the stock electronics box had no airflow - especially with all the excess cabling.

I turned crash detection back on it and thought it had solved the issue as I had no crashes for about a week. But, it's started again big time. :(   Up to 50 per print.

It would appear that after 20 crashes, it pauses the print awaiting user input, which has cost me many hours on some prints.

I don't like having the crash detection off. I very nearly ended up with a disaster a year or so ago when a roll of filament jammed. The extruder nearly snapped the spool holder off!

I think I'll try replacing the Y axis motor as this appears to have resolved the issue for a number of other people.

Ben.

No burrs or blobs, no infill to catch...nothing. Since turning it off I've been great.

turn of crash detection hi have done since day one never get any layer shift

I have installed Hiwin's on my MK3, which runs absolutely smoothly. Nevertheless, I occasionally received a crash notification and for this reason I deactivated the crash detection. Since that time no problems anymore.

But it only makes sense if hardware errors and incorrect slicer settings can be excluded. Sense or nonsense of deactivating crash detection can be discussed.

wbr,

Karl

However, the crashes often as not occur near the end of the print after the top layers are being printed, so the infill is no longer exposed.

What's your infill setting?

Crashes can be caused by the nozzle hitting infill, especially if using infill patterns such as grid that where filament crosses within a layer.

I'd appreciate a link or two if you have them.
