I have a relatively new V2.4 with stealthburner. It has a Revo hot end. My 0.4mm nozzle is clogged. If I remove the nozzle, I can pass filament through the stealthburner, no problem. With the nozzle mounted and hot, I can get a 0.4mm needle tool in from the bottom, but it's difficult, and I can't get it in very far (1cm?). It will extrude a small amount and is them clogged again.

How do I unclog the nozzle? Take it off the hot end and use a hot air gun? soldering iron?

I have a stealthburner with LDO nighthawk SB. The nighthawk will not lay flat on the two threaded insert mount points. I have not figured out what is keeping it from laying flat. There is nothing obvious in the way.

The first pic shows the position of the two threaded inserts that the board mounts on (red arrows):

The second pic shows the board installed, the upper screw tightened, the lower screw loose (and crooked, sorry). The lower screw cannot be tightened fully due to the gap, it would bend or break the board.

Anyone else have this problem?
