That's going to be a beast!

If you're going to run the stock hotend, consider drilling out the stock thermisters and replace them with standard offerings. You might need some ceramic epoxy to do this (Arctic Silver maybe?). Stock nozzles are good to about 265C by design. Not sure how much harder you can push them.

i aint aiming for much but to keep em somewhat stock with few extras and use the sides to support standard spools with printed clips

Try shrinking your photos by about 50% -- if they are too large, they won't upload.

Biggest up-front challenge people have had with the Cube3 is the non-standard thermister. I don't know if Marlin has a way to manage the installed thermister.
Also know that the 3DS slicer is very keen to bias the non-working extruder temperature. I do not think generic slicers know how to manage this. It could be done on a post-process basis.

V1.14B is a nice stable version. There is an 'upgrade' version and there is a chip reset option both of which free you from the chip countdown.

But than again you are stuck with silly cubify Software...

Does anyone know how much current draw the Stock heaters?

- - - - - - - - - -

The Stock PS can Do Max 5A...thats enough for the bed heater... I have a 24v 20A PS from Siemens(Simantic) to test but will have to look for an smaller PS that could fit under the cube with 12,5-15A

Have a bunch of stepdowns to wire up... ��
