Building a Table for the Ox

The DOX (Don's OX) Table Build


Finally all CNC's in one place in my shop. Both laser and Router are on movable bases

Goals:

  • Strong 
  • Sits on the floor when in operation but can be moved easily
  • Houses electronics
  • Room for a hood added at a later time
  • Space for electronics

Design:

  • Materials: dimensional lumber from big box stores
  • 3/4" MDF thick top
  • Integrated lift: lifts entire table up on casters for movement
  • Storage space 
  • Space for drawers, electronics, PC or tablet

General Parts

Frame parts: 2x4 and 2x6, 96" length
Cam lags: 1/2 x 6" and flat washer.
Most other hardware: 1/4 x 5" lag screws and washers
Top: 3/4 MDF, size to your liking
Shelf: 1/4" fiber board or material to your liking
A rough cut-list for the V3 model below

Initial Build Complete

The table cut and kitted

1/2 x 6" lag screws in cams
1/2 x 6" lags were used in the cams so that the non threaded part of the shaft created a bearing surface as it goes through the frame. However, the non-threaded part of a 6" lag is longer than the width of the frame and you cannot screw that into the end of the cam. To solve this problem after a pilot was drilled in the cam for the threaded portion about 1" of the cams hole was enlarged to 1/2". This allowed the solid shaft to pass through the frame and into the cam material.

The top frame parts were plane'd flat on the joiner




Pretty Flat

Mobility

The main feature of the table is the cam system that allows the table to be lifted 1/4-1/2 so that it can be moved in my shop or on a nice day out into the driveway.

A Simpler Spoil Board?

Image
SPOIL BOARD Google'ing shows that there are a gaggle of spoil board configurations out there. Since my initial build I have been using a spoil board made of particle board with routed T-slots. I used a secondary T-slot board to increase the holding options. This spoil board was made from two sheets of particle board with milled T-slots. The two board were joined in the middle using a lap joint cut on my router. This was material that I had yanked from someones pile of kitchen refinishing remnants. The upper spoil board was also made from particle board with T-slots milled transversely. Practical Work Holding I mostly have been working routing wood and that has driven me to use a different work holding method. The following approach will not work for milling metals at least not anything robust. Tape as a Work Holding Medium After many frustrations hitting the clamps used in traditional work holding ) using a variety or T-clamps) I investigated using tape as a hold

OX 48V spindle control

Image
Background DRAFT WORK IN PROGRESS One of the first steps in setting up the OX for operation is to calibrate the spindle speed vs the "M3" values sent from the TinyG. My first set of tests revealed a non-linearity in this control function. https://plus.google.com/+DonKleinschnitz/posts/AG6gZ7Lxhs7 This caused me to start a search to find, explain and remove the spindle vs speed linearity, the subject of this post.

Circuit tracing The Rio Rand controller was dissembled and a schematic was created. Theory of operation The key elements of the controller's design are: PWM input source choices: external or internal generated PWM selected by jumper External PWM: an opto-coupler interfaces the external PWM to the 555 which in this mode is used as a pre-st
