Re: Water or air coolant for your shapeoko?

I have good results cutting aluminum dry. Dual y motors. I still need to double rail my X. Using a Destiny Tool Viper 1/8 endmill. I'm only taking 0.1mm cuts but could probably do 0.2 without problem.

I need to make a dust vac shoe and an enclosure.

Re: eShapeoko - Problems with Z-Depth

"In theory" microstepping can allow a motor to achieve a high speed. It results in a waveform more like a sine wave. A few years ago I was playing with my own stepper driver using discrete mosfets. I go around 25% greater rpm when I implemented microstepping. This is assuming your controller can gen...

Re: Best Computer for LinuxCNC and Connecting to Stepper Dri

In theory they should work. The big issue with laptops and LinuxCNC is laptops have more ACPI and APM layers running underneath than desktops. At least in years past. Modern systems I'd imagine would be pretty close. This shows itself in higher jitter values during latency-test and then higher base-...

Re: Best Computer for LinuxCNC and Connecting to Stepper Dri

I'm using a PCI card on my Shapeoko with LinuxCNC. Works fine. Biggest problem is it runs at 3.3V rather than 5V. The relay for my spindle needs 5-30v.

You do need to find the address assigned to the card with lspci.

Re: what shop Vac you would recommend for shapeoko

I have the Shop Vac equivalent from Lowes (I like blue). Works fine. Biggest problem is the cheap blue bucket I got from Lowes collapses if I use a 3/4" hose.

Re: 4th axis setup

Does that lathe chuck have a taper? A quick look at the HF website, and I could only find ones with a Morse Taper.

If so, how are you going to accommodate that? Just turn it straight on a lathe? Different size bearings?


Great project.
