Re: New Problem
It's unlikely that a fault on the RAMPS would cause that problem. Check that the stepper motor and axis move freely. Try swapping the motor cable with another.

My two cents is to wire the heated bed directly to your +12V supply without the SSR for a test. If it still struggles to get above 45C with no SSR in line, then the SSR isn't the cause of your...

The original Arduino is opensource hardware based on the Atmel Mega 2560 (?) chip. Buying an original board from Arduino runs $50 - $60 but supports the developer. Everything else is primarily cheap...

The problem is that this prusa i3 printer, called hephestos is made to use the freaduino board, due to the upgrades, most importantly i think the 3 to 5 volt switch, and that it can output 2 amps on 5...

Just did a quick search on Freaduino. It appears that the form factor is the same as an Arduino Mega2560, so it should work with a standard RAMPs board. Neither the 3.3V option or the 2A current...

I agree with Waitaki, just hotwire your fans. I use an all metal hot end with a fan cooling just the fins, not the heater block. Always cool down completely (<30C) with the fan on.

The stepper motors on this is rated 2.5 amps so i think its safe or safer to use the freaduino (is that correct thinking) If i buy this more expensive board, can i then put a normal ramp on top ?...
View ArticleRe: Use Arduino mega 2560 instead of Freaduino Hephestos
The stepper motors will be run by the 12V 5A power supply that you plug into the RAMPs board. They are not powered by the Mega2560. A normal RAMPs board will work with either a traditional Mega2560 or...
