QuotecdruUno won't work, not enough IO pins. Not necessarily true. My first printer ran off of a Duemilanove. You really only need two pins per stepper (STEP and DIR), enable is optional though nice...

QuoteRigor_MI had in mind that some thermocouple came with adapters and you could use something like 1mV/deg. scale. Those do exist. Something like this: [www.frys.com] Why not just get an extra...

Thanks, at that price, i'll just get a dedicated probe ;-) I was thinking of a thermocouple because its more accurate when reading temperature than a normal thermistor.. I have a couple of those in...

Thermocouple usually employs a dedicated IC to provide certain required functions like reference, compensation and amplification. An usual multimeter might have an error like 1-2-3% +/- ~-1-2 digit(s)...

Probably not. Do you have a link for the power supply? Does it have a voltage selector switch?

The problem there is that while the MCU itself on boards like the Mega and Due has a separate ground for the analog inputs, the boards (such as the Due and Mega) have one common ground plane for...

The power supply is from Ebay The description on ebay says 90-264VAC but the label on the unit says 170-260VAC. I've requested the info from the supplier. I'll post the answer (if I ever get one).

Are the analog readings a problem? Most electronics don't even try to get smooth analog voltages, so it appears to be a non-issue. Controllers with analog smoothing are Gen7 and STB, IIRC. Teacup...

HalloThijs, I do have the same problem and I found a schematic of the LCD and the connecting to the mega 2560. The drawing is an arduino uno but the setting is the same as in the 2560. Starting your...

It would have a selector switch on the side to toggle between 120v and 240v if it was compatible with both.

The Ebay vendor did reply and said that it will work with 110V supply. There are no selector switches. I am concerned about using such a cheap PS -- 400W for less than $10 -- but it's what I got in...

Chances are you'll be fine since most use just a Live and Neutral line. They might have an L2 line or something but just ignore it.
