Hi coldfront,
Are you saying that the thermostat is already built in the bed? Because of the lack of instruction for this kit, I read it somewhere on the net, I think it was Instructable.com, it says that I need to connected a 103 NTC in the center of the bed, so I did. Like Jamus, I also thought the thermostat was missing from the kit. Perhaps that's why I have the shut down issue.

Oddly enough that is what I posted originally. Then thought no, I better not write that so as not to offend you, as it was covered a few times. He he.
So I changed my post to reflect info on the atx power supply. I should have left it as is. I wonder if anyone saw it before I edited it.
Either way glad you figured it out. :0)

DUH! I just realized that the switch was pre-set to 220V not 110V, How silly of me!
Yeah glad you figured out the PSU problem, but did it fix the heating problem??

Seems like it does, right now I am running a stress test, I have the hot bed and the extruder running for almost 3 hours now and monitoring it, So far it never drops below the target temperature and it keeps turns back on when the temperature drops below target. So it was the ATX PSU caused the problem.
Unlike yours tho, I do still need the 103 NTC, and did a bit of editing on the Configuration.h otherwise the be heater just won't turn on. Wonder why.
But what the hell, it works nicely now YAY, my first 3D printer!
Thank you very much to everyone for your helps.

just curious. On the top of the extruder, looking from the front, there are two holes, I know the one on the right is for the 3mm filament, but what is the one on the left? Is it for 1.75 mm filament?

Anyone use any LM8uu linear bearing alternatives? The ones included lose balls like crazy and are the crunchiest bearings I've ever seen. I'm thinking of getting some 8mm bronze bushings.

I noticed some of mine were worse/better then other. My guess is they are just cheap ones to make the kit cost effective,

Hi
I just finish to calibrate my Folger tech printer and I need some help, the one thing I didn't do until now is to adjust the vref of the motor controllers because I don't really understood how do I measure them. is there an option in the host program to read these values?

no software option with the RAMPS board, you will need a volt meter. + cable to the actual metal of the tiny adjustable pot, and - to ground.
please use the voltages posted earlier in the thread, the ones i posted from the folks at folgertech as a good starting point smiling smiley

Folger guys just publish a complete PDF for the build process.
to late for me but at the end they show how to measure the vref but should it be without the motors connected? do I need to send something from host app to measure?
thanks a lot, this thread and a few YouTube films really helped me in the building process (before Folger publish they new PDF)

It's about 6"x6"x6".
Pretty cool eh? Not sure I want to add a second extruder yet.
I may buy FolgerTech delta printer next.
Still on the fence. Need to find a good reason for the wife. Or just tell her it's my Christmas present.
It doesn't have to make sense. :0)
