Layer shift from curling up overhang - How to get away with it on the next print

So you've been printing a large print all night and wake up to find a layer shift right in the middle of it!. In my case it was one of the parts for the LACK enclosure V2.

You check your bearings etc and find nothing wrong, so start the print again.

Before you do, measure the height of the layer shift and make sure you are there to watch it.

In my case, it was an overhang which was curling upwards that was the culprit at the end of a long bridging section with fan at 100 % for the bridge, so what can you do to salvage the print that you can see is about to fail - again!.

Use the knob on the front LCD and SLOW the print right down, and I mean right down, drop it to 30% if necessary, possibly lower.

This will cause the nozzle to be in the curling print area a lot longer and will pump heat into the curling print, causing it to soften and get ironed  back down.

Once the curl has been ironed down and another 2 or more layers deposited on it, turn the speed back up to 100%.

This trick can be used anytime you have a piece of the print curling up and going to cause a head crash and subsequent layer shift.

Normal people believe that if it ain’t broke, don’t fix it. Engineers believe that if it ain’t broke, it doesn’t have enough features yet.
