That is why core XY printers are so much better then bed slingers and why I am so surprised Prusa is still releasing bed slingers and expecting people to pay what they're asking.

fun stuff! looks great! wait till you start tinkerCAD/Fusion360!I love this 3D printer so much. I’ve started taking multiple .stl files and putting them together in cura to make special pieces. Also have a torch growing out of the dragon skull I printed
I played with Blender last night.... Woah
do you still need a skimmer stand .stl? I've made a couple of them , would love for you to give them a try
Normally, what you did should've worked. It sounds like the nozzle was put on too tight or it was cross threaded.
bump the temp on the nozzle to 280C, that should help loosen the junk in there.. and Use a proper tool to remove the nozzle. a 1.5nM torque driver by slice engeneering.
Yea I am frustrated as I have two ender printers and completely took apart the 'older' one and put it back together after about 6 months of use because it stopped working. after putting it back together it runs better than it ever did, so I am not completely useless when it comes to mechanical investigation.
The nozzle maxes out at 260 C , I tried running it at that temp for a couple of minutes but still didn't budge
I ordered replacement silicone shields and have a bunch of extra nozzles from when I ordered the blue tubing to replace the junky white tubing that connects extruder to hot end. Just seems so crazy that both printers crapped out on me within 24 hours of each other
You're definitely on the right track, and you seem to have common sense which will make up for your lack of mechanical understanding. If you have a pair of vise grips, get the hot end as hot as you safely can and lock onto the nozzle and try to work it back and forth (trying to break it free). Keeping an eye on the hear block, you might have to use another wrench or pliers to hold onto that.Yea I am frustrated as I have two ender printers and completely took apart the 'older' one and put it back together after about 6 months of use because it stopped working. after putting it back together it runs better than it ever did, so I am not completely useless when it comes to mechanical investigation.
I didn't use an open wrench to hold the block in place. But I don't think it would have helped and here is why. When I twisted the nozzle initially I noticed the heater block would swivel slightly in the same direction. At first I thought I was going to break the hot end completely, but it held together because of the two screws that hold the hot end together snugly. This will be something I try today when I get home, but the brass nozzle literally stripped before the nozzle starting moving. Holding it in place or not holding it in place, the stripping would still happen before anything budges. I am truly at a loss and hoping there is something I can do other than replacing the entire hot end
would it be a horrible idea to take a torch lighter to the nozzle? I Only thing I can think is there is some silicone that got up in the threads and it doesn't loosen until about 280 C so the silicone is locking it in place. will try with the vice grips. I'll take a video of it today when I try again and show all of you what I am working with see if that sparks any ideas
Can you try to heat the block leaving the nozzle a few degrees cooler? That might expand the block enough to loosen it.
I wouldn't use a torch unless you can ensure you're not going to melt the surrounding plastic components and wire insulation.
