I keep wiggling those tiny leads apart, but they find their way back to shorting each other out internal to the cylindrical portion.where I cant insulate them from each other. Has anyone ever sourced the thermosister (round/cylindrical) used in the r1+ outside of Robo? Or one that fits the stock nozzle setup? (I can alter firmware as needed for the value). Alternatively, can someone point me to a verified drop in solution to replacing the entire hot-end under $25.00. I thought i sourced one awhile ago on alibaba, but when it arrived -- wrong size. Side note: Trying to be patient with Robo's customer support, but I keep getting run-around. (Seems the glitch where I can no longer log into Robos' support (not this forum) website, get a password reset, nor create a new account with my existing email is affecting their ability to send me an invoice to pay for one.) Gave them an alternate email ddress, but no invoice. Calling an leaving messages on their voicemail goes straight to /dev/null apparantly. SO I cant get one from them. Sigh.
