Hello
I purchased a MK3 dual power aluminium heat bed from [www.cubic-print.com] .
It ships without NTC so I took a "spare" thermistor of my other 3d printer (QU-BD TwoUp) which is a default EPOCS glass bead. I attached it in the middle hole of the bed and secured it with Kapton tape.
I use a Ramps 1.4 board with Repetier firmware 0.9x.
I did solder 2 wires to the "-" pad and connected both wires with the pin D8-negative and the other wire from "+" to the positive port on D8 aswell. (I am writing this just to make sure all my doings are correct/replicable).
My PSU is an old PC PSU with 520 Watts.
The (yelllow) 12 V rail can provide 22A. This is at least what the decal on it's backside says.
I connected both 12V rails (+GND of course, just to make sure I did not foget anything) to one of each input pins on the Ramps board.
When heating up the bed to 100°C for my very fist print in ABS it takes about 5-10 minutes to reach 70-75°C and from there on it only increases in 0,1°C steps.
There must be something wrong but I don't know what. This is my first print with a heated bed on my brand new Wallace.
PLA without heat bed printed just perfectly fine.
