I am working 12 hour shifts this weekend so it might be Monday before I have time to look at my settings, but I would be happy to share them.
Thanks that would be great :-)

Hi all,

I'm new to this forum and here is my entry.

This trial archives 26 seconds.

In this trial feed rate is 18000mm/min and acceleration is 800mm/sec2, Z height is set to 1mm.

Enjoy :!:

edy555: it looks like you're getting a fair amount of backlash at this speed. You'll need to remember that when you're actually cutting something, especially with the weight of the tool which will give you more issues with inertia stretching the belts.

Ok, so yes I am reviving this old thread. Basically because at the time I thought it would be cool to join in the fun but I did not have my machine anywhere near built. So now I have the CNC up and running I thought I would modify some g-code and push my machine a bit and see how fast I could go. I am sure there are faster machines out there now, but wanted to add my entry! Ran it twice to show I didn't miss any steps.
Looked like about 19 or 20 seconds.

Modified G-code (see attached)

1500 in/min vel. on x and y
210 in/min vel. on z

100 in/sec^2 accl. on x and y
40 in/sec^2 accl. on z

*edit - fixed typo*

Eddy555, you can go faster still.
If you look carefully, your "rapids" are slower than your drawing. You could increase them to be at least as fast.

I might just see if I can run this on my mill and see what it does. I've not got a Shapeoko, yet, but I got one of the micRo mini Mills, which are completely different. The comparison would be interesting though, as the micRo uses leadscrews throughout, rather than belt drives.

I think it's time we saw how fast the latest generation is! Anybody with a shiny new Shapeoko 3 want to help the rest of us live vicariously? :mrgreen:

I want to see the max usable speed and acceleration.
