Glass bed, its not a sticking problem - the print is stuck solid, so it literally pushes it to fall over. Seems better though after cleaning, I'll try the print that usually fails often a little later to see how it goes.

Aaah I misunderstood. The hotend is physically pushing on the print and causing it to fall over? Is it happening at the same height or roundabout? It could be your z-axis rod lubrication or some dust causing the z-axis to not climb as expected because of resistance? The silicone lube mine shipped with gathered dust like crazy so I was having layer lines in my print because of dirt.

It's one of the things I suspected, so cleaned and relubed it over the weekend.

Couldn't really tell if its the same place, but its within the first 30min each time, this is the model:

Now battling under-extrusion with the the new extruder, so going to try figure that out before trying again - think flow at 105% is about right. with my current enclosure, I actually think I should go to direct drive.

I have been struggling with under-extrusion for a couple of days now and have not been able to figure out what the hell is wrong... This morning I found the issue.

Did you recalibrate the extruder e-steps after fitting? I had to when I changed mine... the setting was different to the stock extruder

Also slow down the print speed, depending on the size of the model. Assume your printing vertical? Looks quite small and may have issues around some curves if printed fast.

Does it have a fan inside that's blowing warm air through? Currently using a food dehydrator, might need another one.

No fan, just enclosed. Stable heat from 35c to 50c. Have mine set to 35-40c for new spools whilst printing

No but there is youtube video of someone adding a fan and moving the thermostat for more even drying. Got 4 of them so might sacrifice one to test.

Not sure how it's drying then if it's enclosed...the humidity isn't going anywhere?
 
My normal lighting packed up... Spot the F14 mid flight :D

Heated DryBox Banishes Filament Moisture For Under $20

Not sure, but it works well. There are 2x 4mm holes it the top and front-side of the cover, maybe the heat releases the moisture through them, really speculating though...
 
My metal extruder is installed and I will need to calibrate it now. I built my own dry box for filament which I print straight out of. Used a small blower fan to move the air over the silica packets to keep the air as dry as possible. Seems to work reasonably well. I used to get really bad cracking of the filament as it unspools and have not had it since I started using the dry box...
