Operation

Setup

  • With power off, ensure that you can move the carriage smoothly without it catching or having too much play. If it skips or bumps, clear out debris with a vacuum. (The machine generates a ton of dust, so having the vacuum on hand is helpful.)
  • Check that the belts aren't loose.
  • Ensure that all surfaces are clean so that the workpiece sits flat.
  • If you will be cutting all the way through your piece, put a piece of scrap between the work surface and your piece to protect the surface. (No wasteboard on this machine.)
  • Visually inspect the machine to make sure nothing is broken or out of wack.
  • Plug in both the white (spindle) and black (Motion Control Board) power cords

Workpiece Setup

  • Clamp work to the surface with the toe clamps (in the black bag or clear plastic tub.)
    • Toe clamps need to be pushing down - so that the toe is angled down towards the workpiece - not angled up.
    • After setting the height with the toe's rear bolt, lightly finger-tighten the bolt near the piece.
    • Do not over-tighten: if you over-tighten, the force can pull up the work surface.
  • Check the envelope of the machine to ensure it will not crash into the rear dust guard - the grid of the work surface does not necessarily correspond to the grid in Easel.
  • The clamp down studs are 5mm.

Collet & Bit Setup

  • Put the bit (1/8" shank) into the collet.
    • The further in it goes, the more secure the bit is, but make sure that the flutes are not inside the collet.
    • If the bit is too deep in the collet, it can bottom out inside the spindle when you begin to tighten the collet.
  • Use 14mm wrenches (in the black bag) to tighten the collet. You don't need to over-tighten the collet - hand tighten, not gorilla tighten.

Carving with Easel

Easel is run in a browser, you must log in at Inventables http://easel.inventables.com/users/sign_in

  • Select the correct material for the workpiece.
  • Set the appropriate bit parameters (e.g. upcut, ⅛" shank, number of flutes, bit shape).
  • Create your design, ensuring that you are leaving enough space from toe clamps.
  • Click carve.
  • Turn on the machine by pulling up on the button.
  • Click "Unlock Without Homing." ("Home Machine" will send the machine to where it thinks is home.)
  • Home the machine: align the endmill with the bottom left corner of the workpiece (or wherever you want to set as home). Bring the bit down to just touch the workpiece.
    • (You will need to reset the Z every operation. The machine loses Z calibration after each run, though it keeps XY home information.)
  • Click "Confirm home position"
  • Set the spindle speed with the control knob to desired speed.
  • Click Carve.
  • You may want to have the vacuum on hand to avoid overaccumulation of waste and dust. Avoid starting fires.

Chip Load Calculation

Known Issues

  • You will need to reset the Z after every carve operation. The machine loses Z calibration after each run, though it keeps XY home information.
  • If you're having issues connecting to the Arduino, reboot the PC. It's good practice to start work by rebooting the PC regardless (especially if anyone else is still logged in).
  • If the spindle jams on something and then won't restart, check the fuse in the spindle controller (on the back of the cabinet). There may be spares in the drawer under the machine. It is a 5x20mm glass fuse, should be 6A but we've been using 5A because Home Depot stocks them.

Modifications

Maintenance

Past maintenance can be found under Discussion tab.

Items that still need work:

1. Waste board supports purchased and installed. Entire board is unsupported in the middle, causing it to sag. Recommend getting two $7 20mmx20mmx300mm extrusions (from Inventables or elsewhere) and T-nuts to support it in the middle (this is a common upgrade for this particular machine).

2. V-wheels/bearings on all axis need to be adjusted to a tighter tolerance. Some are not making contact..
