Re: Stepper motor overkill?

Spontaneously I would say the nearer the threaded rod is to the z axis Makerslide the better.

Re: Rather Large ShapeOko

Have you done any measurements how good the repeat accuracy of that machine is? Seems to me like the bigger size would worsen it quite a bit.

Re: Power supply, wiring

The photo's are odd, the plug doesn't match the diagram ... does the connector with the wires look new? Not really - it looks like there was a cable in the top middle (pin 5) which was then cut off and there is still one strand of wire there... You can see that in the photo. Then when I press that ...

Re: Power supply, wiring

Are you aware this is supposed to be kit which can be used by people who don't own any tools besides those which are shipped with the kit? ;)

But of course I own a multimeter, I'm going to check now.

Edit:
The info on the power supply is right.

Re: Z axsis assembly issues

Also, I'll have to make sure my threaded rod and shaft are touching, might have to take out a spacer, my steppers have a very short shaft as you can see from these pics That's a bit off topic in this thread, but I don't think they need to be touching, they should just be far enough inside the space...

Power supply, wiring

Pin4: N.C. Pin5: GND Pin6: GND That means that one cable of each...

Re: Z axsis assembly issues

The motor shaft was a bit long for me too. Probably cutting it would be a good idea. On my machine the threaded rod isn't really far enough inside the coupler so it just about fits, but that's really just a temporary (in this case that probably means "until the threaded rod falls out or if I experie...

Re: Tap broke

I got it out... I used a dremel to open up the hole on one side slightly less than 1cm deep, then got the tap out (sidewards), drilled the hole bigger so the shaft of the tap fits in (to the same depth, maybe 8mm), tapped the hole farther in and used a 20mm screw. Not quite easy to explain with word...

Re: Tap broke

I tried with needle nose pliers. Didn't move even a single little bit.

Re: Tap broke

Look up "tap extractor", there is a tool that fits in the holes around the tap to help remove it. You aren't the only one, there is a thread around here with the same problems where these were mentioned. And yes, definitely use oil, never tap metal without it. They should put a big disclaimer in th...
