Re: original Shapeoko stepper motor specifications

Thanks.

Yeah, I poked around there before. I didn't find any actual specifications.

Most of that is fro the model 2 or newer. (I think the one I have is a model 1 and there are only assembly instructions for that.

There is some discussion there of whether to choose a NEMA 17 or larger.

original Shapeoko stepper motor specifications

Hi, I have an early version of the Shapeoko with stepper motors labeled: OSM ALTN1728S87 Date: 2011 06 07 The ALTN doesn't seem to be in the current OSM catalog and emails to them have gotten crickets. And web searches get nothing on this particular model. It is clearly a NEMA 17 (thus the 17 in the...

Shapeoko dxf files

Has anyone looked at the makerslide dxf file? The dimensions seem a bit off. For instance, the cross section dimension in the dxf is shown at 1.5748. The actual measurement of the slide in my hand is 19.94mm (.79"). Twould appear the dxf geometry has been scaled by a factor of 2. (i.e. 2 x .79 = 1.58)

Shapeoko V-wheel Constant Clean Out

Hi,

I poked around the other threads and found nothing about this.

Everytime I run a part on my Shapeoko, eventually, some cutting chps get into the wheels and cause jerky motion of the axis, thus creating scrape.

Am I the only one having this?

How are others dealing with it?

Regards,
Mac

LinuxCNC StepConf and Shapeoko X & Y Calcs

Hi, I'm curious how the calculations for the X & Y axis are made to determine the leadscrew pitch given the .08" pitch of the Shapeoko belt, 18 tooth gear on the motor and typical 200 step motor. In the details shown here: http://www.shapeoko.com/wiki/index.php/EMC2#StepConfig the pitch is set to .6...

Z axsis assembly issues

I have found the delrin nut to be very tight on the threaded rod.

Is this common?

It also appears that my motor shaft is a tad long so I can't put both jam nuts on the rod.

motor mount registration hole size

So the NEMA 17 spec says the diameter of the registration boss is 22mm (.866"). Is there a reason the hole in the mounting plates is 13mm (.511")?

This results in the need for the washers shown in the video to prevent warping the mounting plate.
