Re: Ran the Circle Diamond Square test

When I cut out my router mounts from HDPE I ran at a pretty high feed rate and plunged .030" per pass. This was with a 1/8" diameter 4 flute end mill, not a Dremel bit. Seemed to work out pretty well. I got a lot of melting and build up on the cutter at slower feeds. As a matter of fact, I was just ...

Re: Ran the Circle Diamond Square test

2.5 hours? Wow. What are you cutting? I used MDF and the program ran in about 45 minutes. I just made up the shapes in LibreCad and used CamBam for the programming. I figured if I made the shapes "real" dimensions it would be easier to measure. The more I use CamBam, the more I like it. I think I'll...

Re: Ran the Circle Diamond Square test

Also, as another question, how does one ensure that the two motors on the Y axis are on the same place on the belts, cog wise. Is it important? I have the feeling it may be...

Re: Ran the Circle Diamond Square test

I'll have to put a square on the part, I didn't really think of that.

Hmm. Squaring up the X axis should be entertaining... Any suggestions on how to start?

Re: Having trouble updating grbl on my Seeeduino

Just to follow up I ended up purchasing a USBTiny AVR programmer from Adafruit and flashed my Seeeduino with GRBL 0.8c with no issues.

Re: Seeeduino v3 does not work with grbl 8c

Just as a further note, I bought a USBTiny AVR programmer and flashed my Seeeduino with GRBL 0.8c the other day.

It works great, so I would suggest you are looking at a hardware problem.

Ran the Circle Diamond Square test

I made up a Circle Diamond Square test and ran it on my ShapeOko. c-d-s-2.jpg It looks pretty nice, but measuring it shows that I appear to have a backlash issue. These are the dimensions that I used to generate the G code: sq-dia-cir-2a_640.png These are the measured dimensions on the finished part...

Re: Limit Switch Wiring

I purchased the same switches as you and have not wired them up yet.

I believe that this is close to what we will need to do: https://github.com/grbl/grbl/issues/182

I'll write it up when I do mine, but I don't know how soon I'll get around to it.

Re: Will's Build

Did you glue a bottom skin on your torsion box? I can't tell from the photos. I've been reading up about torsion boxes and it's the skins on the top and bottom that actually provide the stiffness. If you didn't put a skin on the bottom it's not a torsion box and it won't be nearly as stiff.

Re: A Thanks to Edward for This Great Project

Indeed. I bought my kit and it bolted right together.

I'm very impressed with the design and quality. I was thinking of making my own CNC mill and there is no way I could have done as good a job for as low a price.

Congrats and thanks Edward!
