@bearer said in Question about using existing and some new parts with duet 2:

PH

Completely missed that there was a post saying 6 pin ph in it.

I just realized after putting together some cables.... The ones for the stepper motor are smaller and so the JST-XH 2.54 pin spacing connector doesn't fit on them. Any idea as to what connector they are?

The stepper motor connector is the one on the right and on the left the JST-XH I was suggested for size comparison.

Would it be ok to use tinned copper wire? A lot of the top amazon hits when I am looking for 24 and 16 awg wire is tinned copper. I want to say 90% of them... I hear they can cause shorts because tin flows under pressure or does this only apply if you tin the end of the wires yourself?

Edited & updated my last post so photos show.

@Veti So the connectors I want are jst-xh connectors to extend a few short cables.

@bearer I plan to just do that for most of the cables replace the connector on the end but a couple are super short so I figured making a extension cable for them may be easier,

So I just realized something else. The connectors my cables for the endstops, stepper motors. and temp reader for the heated bed currently use won't fit on the duet. So it means I am going to get some crimpers to fix the cables. For some of the super short ones like the fans I want to make a male connector to connect to their current end then a female of the correct type for the duet. The longer ones I can just cut the end strip it and add the right connector. The one problem I run into is whenever I search for male connectors they are always pcb connectors not ones to use at the end of a wire like you can sometimes find on fan extension cables for computers. Anyone know the wording I should use to find some of these male connectors I am talking about?

Anyone know of a guide so I can find what connectors my current cables use as well? I'm adding a few photos that may help. The first2 are examples of the connectors that my ender 3 uses for all it's electronics after that is a fan connector for one of the fans I bought.

Just got multimeter in and tested 1-2 and the 3-4 pins have the exact same reading!

However I do have another question now that I think about it. Someone on the comments awhile back on a fan I bought mentioned that the 2 wires were swapped on their fans so the red wire was actually black and the black wire was actually red. Is there a way to test for this before plugging the fans into the duet?

Would I get noise on a cable 3-4 feet? Also when you say size appropriately do you mean use slightly thicker wire?

I just want to take a moment to thank everyone for their responses so far.

Ok so get a multimeter and measure 1-2 and 3-4 on the 4 pin side of the cable and make sure the readings match. Just to double check because I don't really fiddle with electronic internals. The connector needs to be connected to the stepper motor using the side that has the 6 pins when I am using the multimeter to check the 4 pin side correct?

When it comes to the distance for the cables I want to extend I'd say about 3 feet on the short end but likely around 4 feet. Will that be ok for the heated bed and other things like fans, stepper motors, & hotend? I want to keep my electronics one ikea table down the enclosure I am building.

Ok, so the 4 connections in the exact same order they are already laid out in I assume?

I do have another question... I sort of want to move my box on a shelf below my printer and would need to extend my cables for the heated bed ... Anyone know of a safe/easy way to do it? I've seen suggestions about using xt60 adapters because they can handle up to 60A and can be used in a lot of hobby electronics would this be fine or do you all have a easier suggestion?

So I have an additional question upon further inspection of my cabling. This is in regards to the ender 3 stepper motors. The stepper motors have 6 pins with the cable only having 4 wires coming from it. On the part that connects to the stepper motor (The side of the cable that has 6 pins) it has a wire then empty spot then two more wires then an empty spot then one last wire. Should I keep these cables exactly as they are like with the endstop or what should I do?
