Re: Azteeg X3 and external Mosfet connect-up Question...
I don't think you can connect that board directly to the switched mosfet output. It is designed to connect to a digital output, there should be a spare pin on one of the expansion headers.

Great to hear Bob! Can't wait to see the latest revision with the new E-Stop electronics. At that point, I'll get one made for myself and start hammering it. ;) FWIW: My local hackerspace has a whole...

DC current. The V+ connects to one side of a load, that is called high side. The GND connects to the other side of the said load, that is called low side. In mosfet the gate voltage determines a...

From description it seems certain axis stops when some other axis endstop is triggered, then first axis endstop is never reached to stop the other motor from moving. I think endstop configuration may...

Hi Roy, Thanks for the prompt response. I do have the cover as in the pict above, so I'll try my fan in the H-END3 (D16) connector as you suggest. One final question... In Marlin do I simply change...

Have you tried the M119 code to see what endstops the printer thinks are triggered? If it's endstop related, this is probably the most useful tool you've got.

Hi, I wonder if anyone can think of any reason why my Arduino (Mega 2560) and all stepper motors on a RAMPS 1.4 all have been destroyed. I was moving an end stop, and had switched all motors to off in...

Silly question, but why "add 12V regulator for 24V operation" for power for to the due I can understand But.. 24volt HBP are becoming more common for larger areas and heats up a lot faster, and...

Command? No. they send 3 * 5v signals, enable, step and direction. And enabling it without moving it is normal. I suspect you plugged the endstop into + and -... creating an instant short.. But that...

View ArticleRe: RAMPS for Due!
If you are not sure if board would be supplied with 12v or 24v and want to allow both without any change, may use a 9v regulator, where 9v is good enough to run mosfets gates. Also 9v would be perhaps...
View ArticleRe: Which LCD display works with Ramps 1.4?
I would think first of firmware, e.g. i2c if firmware supports it, then its fine, but otherwise not. I think repetier supports lcd via an i2c expander and if that is what you want to use, then it...
