First RepRap build - WIRING HELP PLEASE!!8-) ok - Finally got in my electronics today! completely assembled ramps 1.4 kit from Ultimachine. The Motors I had gotten dont have the standard r/bl/g/bk wiring. I got mine from makerbot, and they have a connector on the body (I think they are hybrid motors) with 6 pins, however the included harnesses are 4 wires - or/blk/yel/red. has anyone used this type of motor before? looking at the wiring schematic for the ramps on the wiki it shows left to right - red blue green black. which would indicate a+ a- b+ b-. however its screened on the board 2b 2a 1a 1b. im kinda confused on this and was wondering if someone could shed some light on this for me... I just dont want to burn something up.

In the mean time im having issues just getting the sprinter onto my mega - keeps getting write errors....
alot to learn all at once - arduino programming - stepper wiring and setup - pronterface - etc...
but I do dig it!!
Thanks for all the help!]]> Parabolic General Wed, 12 Oct 2011 09:57:46 -0400 https://reprap.org/forum/read.php?1,101007,101044#msg-101044 Re: First RepRap build - WIRING HELP PLEASE!!8-) https://reprap.org/forum/read.php?1,101007,101044#msg-101044
I'd be suprised if could burn the motor out by wiring it wrong, more likely it will work or don't work.
just don't try keep it on for an extended period in a wiring configuration that does not work.

I'd be a little worried about the board, but if you find which contacts have the highest resistance, you should be ok.]]> se5a General Wed, 12 Oct 2011 02:32:34 -0400 https://reprap.org/forum/read.php?1,101007,101019#msg-101019 Re: First RepRap build - WIRING HELP PLEASE!!8-) https://reprap.org/forum/read.php?1,101007,101019#msg-101019
Coil order A+ A- B+ B-
Board order 1a 1b 2a 2b]]> Sublime General Tue, 11 Oct 2011 21:36:20 -0400 https://reprap.org/forum/read.php?1,101007,101014#msg-101014 Re: First RepRap build - WIRING HELP PLEASE!!8-) https://reprap.org/forum/read.php?1,101007,101014#msg-101014 in other words- it doesnt say a+ a- B+ B- on the board - just 2a 2b 1a 1b
assuming the b is the return or the negative, that would make sense...
again - just dont want to burn these up out of the gate.]]> Parabolic General Tue, 11 Oct 2011 20:05:08 -0400 https://reprap.org/forum/read.php?1,101007,101009#msg-101009 Re: First RepRap build - WIRING HELP PLEASE!!8-) https://reprap.org/forum/read.php?1,101007,101009#msg-101009


To use them as 4-wire you use (A+ and A-) and (B+ and B-) and DO NOT USE (A and B )
