My CRP 48 x 48 build [URL=]http://www.cnczone.com/forums/open_source_cnc_machine_designs/144173-crp_4x4.html[/URL]
would these PID controllers work for the hot end?They seem like a really good deal.
I have one like it that I just started using for the heat bed.
Works great for that, but you will also need a thermocouple and an SSR.
My thermocouple was only about $7 off Amazon.
I paid $40 for the SSR, but Ebay carries them a lot cheaper. Mine came from Automation Direct.
Next project for the Prusa, a mini router engraver attachment.
I have to finish making this new better X carriage first, should be more stable than the 3 bearing unit I'm using now.

Thought I got the rotary tool at Harbor Freight but don't really remember.

Please look at these features for me and tell me if the SSR is inclusive to this unit or just controls voltage to an SSR.

DUMB QUESTION : after looking on Ebay I have my answer

No. The picture is of the one that I have made by Mypin.
For that model, it needs a model number that starts like TA4E to be able to use the lower voltage to run this. Without the E, you have to connect it to 110 volts or anything from 80 to 260 AC or DC.
It does come with one little relay inside, but that is only an alarm relay. It's fairly small.
It only controls the control voltage for an SSR. My SSR is nearly as big as this Temp control. The control voltage to operate the SSR is like 3 to 32 VDC.
I run my heated bed on 12 VDC @ 15 amps, so my SSR can run something 3 to 200 VDC @ 25 amps. Plenty overkill.
There are better places to get these from than Buy.com I think.
I'll add a few links shortly.

This is the thermocouple I bought to use with the heat bed.

Not sure what you would use for the hot end though.
