Re: Minimum Footprint Dust Shoe

Thanks. I ordered some (looks like amazon has the best price in town). I noticed in some of your posts that you suggested using acetate to smooth out fuzzies left on milled plastic surfaces. I've been using nail polish remover which doesn't work well. What variety of acetate do you use. Thanks.

Minimum Footprint Dust Shoe

Like many folks, one of my first projects after getting the machine up and running is to build and install a dust collection system. While dust shoes that have a vacuum attachment on the front of the spindle are not issue for those that have an extended bed, they gobble up a considerable amount if t...

Advice on Misumi Extrusions

I am trying to obtain the materials necessary to widen the X axis and in the same time provide rigidity similar to the makerslide dual X arrangement. In reading various posts it looks like a Misumi 4040 profile is a good option. The basic question is which series (I find the Misumi web site very con...

Re: All Axes Gone Haywire – Shield Failure?

That was it again (bad Y axis motor connections ). All axes working great. I ran a fifteen minute job using temporary wiring with perfection. It looks like I was a victim of my poor soldering during the initial build. Fortunately, with a better soldering iron, my soldering skills have improved somew...

Re: All Axes Gone Haywire – Shield Failure?

As usual, you are correct. A continuity “shake” test is not practical on my set-up as the wiring is secured with aircraft style four pin connectors . As an alternate, I cut my soldered motor leads and connected the Z axis directly to the shield (see photo). The Z axis worked like a charm. It has nev...

Re: All Axes Gone Haywire – Shield Failure?

Thanks for the input. I've gone though the driver swap out drill a couple of times. Everything will appear to work individually and then falls apart when I hook up all the axes. I also did a continuity check between the driver pins and the proper Uno pins. I'm essentially going to start over with a ...

All Axes Gone Haywire – Shield Failure?

I initially reported a Y axis problem under item http://www.shapeoko.com/forum/viewtopic.php?f=4&t=1947. Things have degenerated into random problem that has affected every axis at various times. My current test configuration is as follows: Buildlog.net Shield Four Pololu A4988 Black Edition Drivers...

Re: Y Axis Gone Haywire

I am still trying to pin down the problem. Here is s very short video that attempts to illustrate my problem. You have to look closely to see chattering of the Y axis pulley. The sound is more telling. [youtube]http://youtu.be/MYPoJVvkxJE[/youtube] . The other Y axis worked OK. What’s strange is tha...
