Re: BAM&DICE an new RAMPS compatible electronics
I like the idea, but im not so sure the mega family has much life left in it. Another DICE board to consider making is around the [www.trinamic.com] 2.6A, 256 micro stepping and some of their other...

Does the power supply work ok when connected to the hot-end? Also, try disconnecting the heat bed wiring to D8 and check for any shorting between the wires (which will include the pcb heat-bed tracks)...

View ArticleRe: Power supply shuts down when heated bed MK2a is connected.
Yes, the hot end heats up and gets hot enough that the thermistor reads 230 degrees and it can melt ABS. No problem with that so far. I'm not sure I understand what you are suggesting that I try; am I...

I see no reason why not. The board is designed for mounting on top of an Arduino by itself though, so you'll have to mount it separately and run wires to it from the Pololu sockets on the RAMPS. You...

View ArticleRe: Power supply shuts down when heated bed MK2a is connected.
Yes, that's correct. I have heard of some Chinese heat bed imports (which I use) that are shorting to ground through the corner mounting holes
View ArticleRe: Axis Calibration
They do move in both directions. Do you also build a rostock too? if yes it would be very nice if you could share your configuration.h file with me and the other changes you made in the firmware.

That trinamic chip is very nice, although not cheap. Would also fit perfectly for a 3.3V Arduino Due compatible Shield with 3.3V DICEs. Thank you for the hint. Dominik - 2PrintBeta
