Making sense of the BOMs

Development Hardware

I am trying to sift through the various BOMs to try to isolate the connectors needed for the Taz 5 head. After chunking two sheets, I think I have whats needed. I think. I am missing the part number for the pins for the mini-fan plug.

Fans:
CONN TERM FEMALE 22-24AWG TIN EL-MS0059 WM2510-ND
CONN HOUSING 2POS .100 W/LATCH PC-CN0001 WM2900-ND

CONN HOUSING MALE 2POS .100 PP-MP0059 WM2533-ND
Male pin, 24-30AWG tin crimp EL-MS0058

Stepper/Hot End:
Connector, 4 pin Male housing with latch EL-MS0061 WM2535-ND
CONN TERM MALE 22-24AWG TIN EL-MS0205 WM2517TR-ND

Connector, 4 pin Female housing with latch EL-MS0062 WM2902-ND
CONN TERM FEMALE 22-24AWG TIN EL-MS0059 WM2510TR-ND

Another thing I am trying to sort out is the female pins. The Lulz sheets call for WM2510. There is also a WM2569 that appears similar. Whats the difference? WM2569 is more expensive so what are you getting for the extra price?

I and wanting to match whats on the Taz5 so I want to make sure I am ordering the proper connectors and pins.

Also, the heater on the Hex hot ends from reprap is 12v. Is the Taz5 heater 24v? If so, where do I order one, they aren’t in the Lulz store? Where is the part number? Manufacturer? I couldn’t find a heater in any BOM that I looked at.

I’ll have to check, but the E3D 24V heaters look to fit the hexagon heater block… that was the closest I could find.

So the heaters are indeed 24v?

You have an E3D hot end? If so, how do you like it compared to the Hex?

I’m not sure if the hotend is stepped down to 12V on the Rambo. Haven’t gotten around to checking with a voltmeter… was really hoping I’d come across it in reading. I suppose its easy enough to put a voltage regulator too…

E3D-V6 comes in a 24V version… I originally bought the 12V hotend. Then bought two replacement 24V heaters. So I should be covered even if its stepped down. :slight_smile:. Couldn’t find a 24V specific hexagon, so just bought whatever was out there… And plan to replace the heater with the spare 24V E3D.

I haven’t replaced my current LB hexagon… Need to print out the carriage, j-plate and rest of extruder. Honestly considering going with a more compact direct drive extruder… maybe like Printrbot’s direct drive, which has a hobbed gear and idler connected directly to the stepper motor. Put that close to the rails and a Bowden in front for dual extrusion. Hope to cut out a nice aluminum j-plate when the CNC gets here… after a bit of practice of course.


Aesthetically, the hexagon looks cooler than the cylindrical heatsink of the E3D. :slight_smile:

Yea, before I order two E3D’s I am going to throw a meter on the heater pins and see whats across it. I can’t imagine they went with 24v power supply and fans and then step the heater down to 12v. That wouldn’t make sense. But, hey, better to measure it and make sure right?

Quick incomplete answer, but about the heater it is 24V. Not sure offhand about all the pins etc.

Thanks Jebba. Put a meter on it tonight and got 22v across it at the connector pins while it was heating. I presume the other 2v was wiring loss while it was drawing current.
