I would like to know if:

1. I have a Ramps 1.4 control board on a Prusa i3 Mandel printer (HIC) reworked...

my hot end is a J-Head from (China), what is the max temperature that this head can operate at?

2. On my Ramps 1.4 control board can I set it to operate at 260 plus C. ) 2016 MarlinFirmware with up dates,

I would like to use Nylon to print with and I understand I need more heat 255 to 260 is best.

when you say "my hot end is a J-Head from (China)" is it made from metal or peek? Chinese seller have a habit calling an all metal e3d copy a Jhead and 260C at the upper limits for either as its possible there be a ptfe liner inside, ptfe deteriorate/deform above 260C, so ideally 245C should be Max temp.
