It is a pretty new meter and does autorange, and the reading I get is 0L, which I thought was a zero reading?by vfwfw - Prusa i3 and variants
I was measuring directly from the D8 +ve and -ve terminals, but when I measure from power ground I get the 12v as you suggested, so that's not the problem. The board I'm using has the yellow poly fuses, and I have power going to both the 11A & 5A plugs (I assume you are talking about the green power socket), which are both showing 12v. However, I'm not sure if I'm measuring properly, but whby vfwfw - Prusa i3 and variants
Thanks for the reply Dust, I assume you mean 100k Ohms for the thermistor (I am still learning about circuits/electronics). So, if not reading any voltage at D8, D9 & D10 I also assume that means I have a faulty Ramps board, or could it be that voltage is only applied when the relevant command is given? In other words, could it be showing no voltage at because the thermistor is registeringby vfwfw - Prusa i3 and variants
I am building an i3 clone with an e3d v6 hotend and a heated bed, and have loaded the marlin software to my Ramps 1.4 However, Pronterface is not registering any temperature for either the hotend or the bed, and when I try to set the hotend and bed temps I get an error saying that Mintemp has not been reached and it wont heat either. How do I tell if the thermistor's are working? It seems unlikby vfwfw - Prusa i3 and variants
