Heted bed not integrated into Ramps?

Hey everyone,

I am wondering if anyone uses a heated bed for ABS (up to around say 110 degrees) for their printer?

I ask because I am just having so many problems trying to heat a bigger bed with 12V, and it's all because of the heated bed.

I am wondering if there is anything I can buy/build that would let me say plug into a 110V outlet that will allow me to control the temperature like Ramps does.

I would like to be able to heat a bed up that is anywhere from say 300mm x 300mm up to even say 500mm x 500mm


Thanks.

Possible, sure. Get a heating mat for 110V, leave the thermistor as is and connect the mat to the RAMPS' MOSFET via a solid state relay. Works well, except if you try to heat with PWM or pour water over your printer.

Thanks for the reply!

This is all a bit new to me so please bare with me on this questions.

First off, I did some digging on heat mats, and everything I saw was around either for under flooring, or for seedlings. What type of heat mat would work for this application?

Second, I am not sure I understand how to execute connecting the mat to the RAMPS MOSFET via a solid state relay. Can you either elaborate for someone pretty lay in electronics, or point me in the direction of a post or blog or something else that I can read how to do such a thing?

Thanks agian.

A solid state relay has a low voltage input and high voltage o/p like this...
