The right stepper for the right axis

Post by Bunker195 » Fri Apr 24, 2015 2:26 am

Don't be like me and put the wrong steppers on the wrong axis -

The assembly manual gives the instructions near the end, so, in case you don't read the instructions to the end before you begin assembly......

The steppers with the long wires are for the Y axis and the short ones are for the Z and X.

I was so bummed when I realized at the end that I had to swap them all -

Don't be like me.

Please don’t take this the wrong way (I find I have to post messages like this so that I won’t try to update the wiki w/ information that’s already there)

@Bunker195 - Sorry about that. I just looked back through the instructions and realized there is very little information on wiring other than the second to last page, which by itself is pretty weak. I'll need a few pictures to explain this, which I'll need to add the next time I'm by my machine.

The way to do the wiring, and this will make the long vs short make more sense if you're looking at page #34 of the instructions -

The Short wires need to be on the Y axis motors, the ones bolted to the gantry side plates. Those wires are static. Plug them into the Y ports on the controller, then zip tie each one, around it's middle point, to each of the Y axis tie-downs (tie down points #2 and #3 on the print).

The longer leads goto the Z and The X motors. The way to wire these up is
- Place a self adhesive tie down right in the center of the top of the X axis extrusion (Self adhesive tie down point #1 on the print)
- plug each on into its respective controller port.
- Slide the X axis all the way to the right side of the gantry (from the rear view).
- To rough out the zip tie placement, hold the wires against tie down point #1, then slide the the carriage all the way to the left side.
- If the wires didn't catch, put a zip tie around the wires through tie down point #1. If the wires catch, give it a little more slack and try again.
- Once the wires are tied down to point #1, use a couple more to zip the X and Z wires together to build a small bundle.

I'm sure the written description is clear as mud. I'll try to add pictures when I get a minute.

Seemed fine to me: http://www.shapeoko.com/wiki/index.php/ ... o_3#Wiring

Though I didn’t bother w/ more than spiral cable wrap and zip tieing the router cable — debating about the X-Y- cables.

I did the same mistake, mixed up the short and the long wire. :cry:
I think the people in batch one will iron out all the little problems, but for some of us CNC beginners these little problems, are at least for me are a big headache !
In my opinion there are too many places to read and looking up for information on different items.
Back in the old days like with the books they had an alphabetical INDEX with page numbers, which was made it easier to find things. ;)

Overview here: http://www.shapeoko.com/wiki/index.php/Overview

Pretty much everything is in the sidebar, and there's a search feature, and one should be able to limit oneself to the wiki and its links. If there's some other information you'd like to have there, let us know. If there's a better source of information let us know. Beats the situation before there was content on the wiki which was that one had to ask Edward or do a 'net search or puzzle it out oneself.

If you'd like to have an index, feel free to get an account on the wiki and make one.

If you believe the wiki could be better organized, please feel free to suggest improvements here: http://www.shapeoko.com/forum/viewtopic.php?f=17&t=5551

If you want a book, we list those too: http://www.shapeoko.com/wiki/index.php/Books
