    Sounds like a nice upgrade Bill, congratulations. I've heard a lot of good things about the smooth steppers. Are you noticing any difference in performance?

    Just out of curiosity, did you consider the CN-100 USB motion controller? (CNC4PC sells it as well as others). I mainly ask, because I don't really understand what the difference is between that and the smooth stepper.

    I have one suggestion for those who choose to work with old computers instead of upgrading. Win XP SP 2. It runs so much better than SP 3. Just keep it off of the internet.

    Matt,

    I briefly looked at the CN100 USB motion controller. I didn't find enough data from folks who were using it to make me choose it. CNC4PC has good products so it is probably exactly what they say it is. You should try one and let us know.

    I chose an Ethernet controller because I felt it did more and suited my needs better. Fairly soon there will be a bunch more choices on the market. Hopefully folks will share what they learn with us.

    One other reason I chose to get the Smoothstepper directly from the manufacturer instead of CNC4PC was the shipping costs was much less.

    Bill

    Good to know Bill.... Good luck with your new set up

    Keep us updated with any performance observations. I seem to recall reading that the Smooth Stepper condithions the pulse train signals to be a more distinctly shaped wave form.

    Matt,

    It has been over a few months since I upgraded to the Ethernet Smooth Stepper and I have to say it was a good decision. The machine has been running without a hitch since I upgraded. If you want to use a modern computer or Mach4, I think it is a good reason to change.

    I was worried that I might have to do something special to run the SmoothStepper with The Makers Guide Triple Edge Finder but that is not the case. It immediately recognized my probe and works just like before.

    I recently was asked to make a sign for someone to display on their camper. I did the layout and got an OK from the customer. Then I began cutting and painting.

    Next i cut the texture into the background. This was the first time I tried the texture feature in Aspire. I was sweating bullets when the big Cove bit got near the finished 3D carving, but everything was fine.

    Then I ran the profile cut out.

    I stained the wood with a light colored stain from Minwax and sealed with Spar Varnish. Sadly, I forgot to take a picture of the finished sign before I delivered it. Attachment 236890

    Here is how to use tapered bits with a touch off plate.

    I recently made some stools for a student at a local college. It was a quick, fun project.

    How accurate is this with a 3 flute bit? If one flute was perpendicular to the edge, it seems like it would not find the exact center?

    The real answer is close enough for most wood projects. Since most people don't create tool paths that touch the edge of the work piece, most timesyou really only want a repeatable position to start from.

    If you have a really weird or difficult bit like an O flute or odd number of flutes, you can always use a metal dowel pin to center instead. The center probe is only usually done once. In the job setup. It would only takes a few seconds to switch to to the bit you plan to use afterwards. Set the Z zero and cut.

    I don't usually edge find again when I use multiple bits. The center of the router spindle remains the same. Just reset the bit height after tool change is all that is needed.

    My suggestion is to try the 3 flute bit and check. You could also hand rotate the bitt (unplug the power first) during probe.

    When your CNC homes to a set of limit switches and your router is cutting the perimeter of the work piece, all that's really important is that you work piece doesn't move during any of the operations. All you have to do is set up your work coordinate system (WCS) with 0,0 over the bottom left corner of the stock and go to town. If you have to execute a manual tool change, just make sure your program for that cutter references the same 0,0 point, touch off to reference your new Z and hit play.

    When I set up our first CNC router at work, we used to cook all of our G-code in relative (incremental) mode and touch off the part to set 0,0. After several years of dubbing along like this, when we set up our second router we learned to run in absolute and to use G92 to set up a WCS and never looked back.

    If for some reason you have to route geometry on a parts that has already been cut to their finished size, the quickest way to register to the part, IMO, is to set up a temporary fence by screwing down a 1x4 on the bottom edge of the approx. location going L to R and at the left edge running T to B. Then jog to z=0 and trim the bottom edge. Then jog down the radius of your cutter and set Y=0. Repeat for the left fence and set X=0. Now you can quickly and accurately register all of you parts to the machine by securing them tight up against the fence. Wash, rinse & repeat. :^p

    I honestly don't think I've touched off of a part to set X & Y on our router in 5 years.

    Not that I don't think that Bill's clever little gizmo isn't really slick... It is VERY clever indeed.

    Someone asked me what V Bit I was using when I made that sign. It is a Laser point bit. I wrote a blog post describing it V Groove Bits - THE MAKERS GUIDE.

    I have been pretty busy lately upgrading a Grizzly G0704 to CNC. Making more modifications to my CNC Machine and starting a podcast. The CNC Router Tips Podcast.

    Check it out.
