Help with Prusa i3 m-505 A8 bed & extruder temps

Hi, Just finished assembling above name printer. I've worked my way through many issues but at this point I'm having issue with temps.

I'm attempting to perform the very first print.

When I hit Start print, The extruder temp begins to climb and I've let it go as high as 286. I'm really not sure if the screen is showing c degrees or F degrees.

Anyway; even at 286 the bed temp hasn't yet moved. The default extruder temp is at 200 and default bed temp is at 55c. I have the ext. max set at 175 and the bed max at 110. Any suggestions?

Any help would be greatly appreciated! Thanks, Tony

Is anyone out there willing to help?

Hi,
I'm kind of a newbie but i can give you some stuff to get sarted with.
First does your bed heat alone or not at all?
If it does that could be an issue due to your power suplly not being powerfull enough. I believe 250w is needed. If that part is right it may come from the section of your heatbed wires. They need to be quite strong. If you dig around in the topics you'll find what it is suppose to be.
Second you seem to have a problem with your firmware. Did you install it yourself? Is your printer from a china or is it a bit more fancy (makerbot etc...)? Same there's few topics discussing of how to set up you eeprom and so on.

Again i'm a newbie myself so i can only help you to narrow the problem.
Good luck.

Thanks for the suggestions. I went over the whole build again and found that I had the bed plugged into the socket on the board. I've got the machine working but other issues have arisen. I'm going to try a new post and hope for some timely help. Thanks again.
