My HobbyCNC Pro kit arrived the other day and several evenings later I had the steppers moving. My son (age 3) and I enjoyed watching the steppers move on the workbench as EMC thought it cut out the standard test image. I also made more progress on the CNC machine build. In spite of several layout errors I have the X and Y axis pretty much assembled. The X axis is mostly dialed in but there is a bit of slack in the end bearing. These bearings may end up getting replaced if I can not eliminate enough play. Sadly I broke a tap while fabricating my stepper coupler so I did not achieve CNC movement as hoped this weekend.

CNC router update
Monday, October 25th, 2010Slowly but surely this project is nearing completion. This weekend I assembled the base and gantry. The remaining electronics and stepper motors have shipped and should arrive this week. There is still a lot of minor assembly and tweaking to be done but it is finally starting to look complete. My good camera was low on battery so I only have grainy phone pictures to share.
CNC router progress
Monday, August 9th, 2010I made some more progress on my CNC router project. Here are all the base pieces put together in a mock-up of what the final result will look like. The black pipes are what the gantry will ride on.
CNC router progress report
Friday, November 6th, 2009I have decided to build my CNC router based on a design by CNCzone.com forum user jgro.
This is a 3D view of the CAD design.
Here is a pile of parts I have completed.
As you can see I am making a real mess in the garage.
Here are the bearing assemblies for all 3 axis. These are made from aluminum angle and skate bearings and will ride on black gas pipe to form a linear bearing.
Here is the back of the x-axis assembly, showing the parallel bearings.
