anycubic vyper upgrade stealthburmer

anycubic vyper is a nice printer, but I don't think its extruder shell is very cool, see Fragmon, https://www.printables.com/model/139677-anycubic-vyper-stealthburner-mod upgraded the shell, I am very excited, but I don't want to abandon the original automatic leveling function, So I find https://www.thingiverse.com/thing:5020211 again Combining the two, I remade the model, although this is not my strong point, the model is not perfect, but I still finished it, I tested it, there was no problem with the printing, I used 0.2 height, 15% fill, 100 speed to make a 35℃-85℃ overhang, it took 41 minutes, not bad. I changed the v6 and the Red Lizard k1 extruder heads, and they were fine. In fact, I was initially worried about whether the extruder would be able to be held in place by the two screws of the self-leveling sensor piece, and it turned out to be OK. Of course, if you were worried, there is a retaining ring under the extruder head, you can remove it and replace it with two long gongs, so you have four gongs holding your extruder head in place. In fact, the most important thing is that the original print head of the machine does not have a suitable sb case, so it can only be replaced by a suitable extrusion head. I didn't use pid correction. Later, I would like to change my vyper into wire rail, and there is another problem, I would like to ask you to help me, how to make the extrusion head temperature of vyper rise to 300℃, I want to make some high-temperature consumables, but it is said that I need to upgrade the firmware, I am sure I do not have this ability, I hope you can give me some help. Finally, I would like to mention that I made the lamp by connecting 3 5V led tubes in parallel, one of which is color changing, so it looks a little cooler!
