Well i figured it out on my own.ordered a new iduino mega r3 board.came in and installed it. Allowed it to install drivers and the boom room temp readings from the thermistors. So the board is bad. Good thing came with 12 month warranty

i know that and thats not the problem. the issue it that the temp is reading 0 at room temp. when it should be reading 24. other printer companys when you turn the printer on it tells the temp of the hot end before you give a temp command. a constant temp reading regardless of whether heated or not ...

0/0 left side is supposed to be thermistor reading while right side is "set temp" 0 degree c is 32 degree f. its 75 in the room

have you received the new emailed pics?

is there a email address to send these pictures to? they're to large to attach

i did that and it still say 0. so does that mean i have 2 bad thermistors cause the bed say the same as the hotend. but if i manually set the temps (230 hotend 115 bed) the printer heats up and the display shows the set temps and the actual temp climbing.

if the wiring was wrong would it not work at all.

temp reaches set point but how accurate is it. room temp is 75 degrees f. printer display say 0.

//--NORMAL IS 4.7kohm PULLUP!-- 1kohm pullup can be used on hotend sensor, using correct resistor and table
//
//// Temperature sensor settings:
// -2 is thermocouple with MAX6675 (only for sensor 0)
// -1 is thermocouple with AD595
// 0 is not used
// 1 is 100k thermistor - best choice for EPCOS ...

Bed temp is set at 1. I had to set the "min temp" to -1 to even get the bed or hotend to heat at all
