Re: Looking for advice of organizing wires.
When I designed my own Delta repstrap, I put the controller and stepper motors on the top. With the stepper motors and endstops all at the top, the only cables that had to run up from the base were...
View ArticleRe: Dual power supply (relay?)
The cheap 12V Chinese LED PSUs generally go up to at least 14V. You can safely feed up to 15V to the Ardiuno/RAMPS combo if you are not running an LCD or anything else from the 5V rail. But you said...

Hey guys thanks for the quick response: Results are: 11.92v @ PSU terminals going to relay 11.94v @ PSU terminals going to ramps 11.70v at relay and 11.30 at bed running max 11.92 at D8 I'm reading a...

According to the spec sheet link you posted above, the heatbed should be drawing 17A when cold. You can measure the actual resistance across the terminals of the cold heatbed, and use Ohm's law to see...

View ArticleRe: question about using a 24v heat bed
That heat bed has a resistance of 2.4 ohms, so it will draw 10A @ 24V. I suggest a 14A fuse. RAMPS is not ideal for 24V systems, because most RAMPS boards have 16V capacitors. But this doesn't stop...
