Knock yourself out.

Disk space is free and infinite after all. :)

Re: What is the smallest z (depth)distance a ShapeOko 2 can

However, realistically with the flex in the machine, the flatness of the bed, and various other factors, I would say that 0.001" would be about maximum precision I would expect.

A precision of +/- 0.001" is pretty tight for the S2. I was able to hold about +/- 0.005" on mine.

Re: Realigning a work piece

Your best bet is to do what real machinists do. Get a dial indicator and find a way to mount it to your Z axis. This is my mount: http://timf.anansi-web.com/wp/wp-content/uploads/2016/02/01-y-cal-1.jpg Then you can run the indicator along the edge of your part until it shows that is it parallel to t...

Re: What is the most quiet AC powered spindle for the ShapeO

Yeah, "quiet" and "30k RPM Router" don't really go in the same sentence.

Your best bet is to build an enclosure.

Routers are not going to be quiet. A VFD spindle might be quieter, but not cheap.

Re: Can I get Universal G Code sender to read out in inches?

I made UGS display in inches. I think what you have to do is configure Grbl to report in inches.

Set $13 to 1

Code: Select all

$13=0 (report inches, bool)

That looks like a pretty nice and beefy controller.

Re: Grbl ignores last part of a helix hole

Two things: When I paste your g-code sample into this online simulator ( https://nraynaud.github.io/webgcode/ ) it does not show a full circle at the bottom of the hole. Best practices are to not generate 360 circles as one G2/G3 command, but rather to break them into quadrants - using four G2 or G3...

Re: Where can I find the Z axis pully system for ShapeOko 2?

Well I just went and looked. I thought I had a Z axis upgrade kit, but I can't find it.

Either I have misplaced it (very likely) or I sold it with my old Shapeoko kit. Sorry.
