How to connect P2 to melzi?
Okay, I bought a Panelolu2 from T3dP3d on EBay, with an adapter board for my Melzi. No instructions came with it, and now I am confused. How do I PHYSICALLY connect the P2 to my Melzi? Do I need to...

Yes, you'll need to solder in a 5x2 header where there's currently just through holes. The board plugs into the 5x2 header AND the ISP header (the existing 6 pins already there) so that the adapter...

I have been made a generous offer of some free delta printer hardware if I add delta support to the Duet firmware. Otherwise, I would not attempt it - because untested code is invariably broken code.

Thanks! I have some header pin strips, so shouldn't be a problem. It would just be nice if T3DP3D would document this, to avoid confusion.

Turns out Radio Shack has 12-volt LED's with integral resistors, so problem should be solved. Not having dealt with LED's very often, I am wondering - will they burn out if you try to run current...
View ArticleRe: Which LED/resistor combo to use?
It depends on the voltage. LEDs are typically rated at 5V maximum reverse voltage, so with a 5V supply the LED will just be off if it is connected the wrong way round. But at 12V, the LED might suffer...

Instead of putting one of those RadioShack LEDs with integrated resistor onto you MK2B bed, I think it's better to put one resistor and two normal LEDs (I use a red and a green one) in opposite...

What diameter of wire do you suggest for hot end wire connecting the heater cartridge and separately for the heated bed? Thanks

Cool, that crimp wire pin would work well. Thanks.

I believe I used 14ga for the bed, 16ga was not quite enough. For hot ends, I usually just strip an old computer cord.

Cool, I'm wiring up sockets to help me switch heads easier, so figured I'd check :)

Hi RichK I will add it to the documentation - the Melzi boards we have had all got those pin headers soldered on by default so It did not occur to us to mention that! Regards Tony

I've noticed some of the Chinese boards don't even have the ISP pins installed. Most do not have the other pins installed even when the ISP pins are there. Out of curiosity, is the P2 capable of...

First check your firmware, that your board type is set to ramps, type 33 or 34 for most people in marlin. Secondly you can check the select, step and direction lines going to each pololu module. they...
