The Shapeoko Forum

Wow that is a beautiful machine. Very nice design.
Good idea on the old PC case for the electronics too.

Changing $5 won't affect your steps/ mm, so as long they were correct before you won't need to change them ( I don't remember the settings off hand but they seem to be in the right range)

I meant the speed set by "default seek" ($5) in grbl. That controls the G0 speed when your Z axis raises up after a cut (you can't directly control it from Cambam). Unfortunately the current grbl uses the same speeds and accelerations for all axes as Will said. I think I used to have my "default see...

My guess is you are loosing steps on your Z axis, probably when it retracts. This would lead to the next cut being deeper than it is supposed to be. Slowing down the rapid speeds should help if that is culprit.

I have been cutting a lot of 1/4" 6061 lately and have had good results with the standard 1/8" 2 flute carbide end mills that I use for everything else (the ones from eBay seller drillman1). I did buy one of the Destiny Viper end mills that I.C. mentioned but it didn't really seem to be any better t...

Very nice design, looks really rigid. Fast too.

I use the tap handle for the M5 tap used when building the Shapeoko. I got the idea from someone on these forums, can't remember who. Works really well and chances are you already have one.

Hi, I chose the 3/8 - 8 thread per inch simply because it was the coarsest thread I could get in a reasonable size (theoretically this would give more speed). It does work well enough though I wouldn't go much steeper without a motor upgrade. It seems like the weight of the z axis becomes the major ...

Wow that is awesome, did you do the wireless with an Xbee or similar? That would be a very handy mod.

Does the DM542A do microstepping? I can't tell from the description.
