Hello




I have a Joysmaker R2 (it's a chinese copy of the ultimaker original but with heated bed and display with controller, and I changed the hotend to the E3D (on this link http://www.aliexpress.com/item/Ultim...596673914.html) that uses the 104gt-2 thermistor (number 5 in marlin's list). My pcb had to be replaced too, I installed an ultimaker 1.5.7 pcb.
My problem is that the original hotend used a thermocouple and the E3D used a thermistor, now it is showing max temp error because the nozzle temp is showing about 500 celsius, but it is working because if I heat or cool it manually the temperature in the display changes accordingly. So I came to the conclusion that this is a firmware setting problem, but how and where can I change this setting? The only firmware the seller's website is the cura instalation that comes with the .HEX file which I can not edit.
I found a website that builds the firmware if I have all the configuration data and specifications, but I dont know where to find this info. I tried to Build one anyways using default configuration and used the 104gt-2, then when I flash it the printer reboots showing the right temperature but then the software in the printer freezes and I cant do anything.
Any ideas?
