A long hiatus due to my garage being too cold to work in over winter! Then other things took priority during spring, but after a shed cleanup I was able to mount the gantry and complete the cabling....

Next up, the electronics enclosure, which I have embedded in the frame at one end (beyond reach of the spindle). Power supply and stepper driver mounted on an aluminium base plate:

While waiting for some fasteners to arrive, I've soldered the PCB for a Beaglebone cape I designed. I'm hoping to use it with Machinekit on the Beaglebone to control the CNC. A ribbon cable will...

Progress on the gantry, which is nearly complete with motors, ball screws, cable chains and limit sensors all installed. I ordered 10mm lead for the y-axis ballscrew but received 5mm; I'll leave it...

After seeking some design advice on this forum last year, I'm posting a build thread now that my machine is starting to come together. My long-term goal for this CNC router is to be able to cut parts...

Rack on the bottom is the answer, of course. I've come up with a solution for both fixed and pivoted motor mount. I will try fixed first; rack and rail are close so I can use a spacer between them...

With upside-down rails, a tight fit with a 20T gear; a bit risky I think?

I considered the rack orientation. I couldn't see how to mount both the rail and rack on the adjacent outside t-slots with the teeth facing down. (Unless I switch to a 12mm x 12mm rack, and used a...

Excellent, thanks! A reality check. I had based my design on raptor, which uses an undercarriage. Now I've reworked the X axis to have the rack mounted on the outside of the frame. A better link to...

I'm a newcomer, currently designing my first CNC router for the purpose of ski-building. This requires a fairly long work area (2200mm travel along X direction). The tool would find use in cutting...

Thanks Toby for this spreadsheet. It's helped me get a ballpark idea of what size motors I'd be needing.
