== 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.
=== 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 ===
* 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.

* 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.
