* Inspect the machine and bed for any debris, especially the ball screw

* ~~Check~~ that the hose in the compressor is attached to the CNC air-assist connection.

* Ensure that the hose to the compressor is attached to the CNC air-assist connection.

* Turn on the air compressor (push red toggle switch backward).

* Turn on the air compressor (push red toggle switch backward). Only if necessary, adjust air compressor regulator to provide 60-80 PSI pressure to CNC if it has been changed. The CNC has a second regulator regulator for the air-assist and should already be at 40-45 PSI since no one changes it.

Note: Spindle RPM DRO in thousands of RPM

1. Remove ~~collet~~ from spindle ~~and set aside~~.

1. Remove dust collector boot from spindle.

⚫

2. Remove collet and collar from spindle and set aside.

⚫

2. Warm up spindle bearing using the speed control dial on front right of CNC router. This is required for the longevity of the spindle bearings.

⚫

3. Warm up spindle bearing using the speed control dial on front right of CNC router. This is required for the longevity of the spindle bearings.

* Step 1: 5k RPM for 5 mins

* Step 2: 10k RPM for 5 mins

* Step 3: 18k RPM for 5 mins

Alternate Spinup: To warm up spindle, dial in half-speed (9), click Spindle and run two minutes; then dial in 18 and run two minutes, then click spindle to turn off.

=== Zeroing Procedure ===

IMPORTANT NOTES:

~~IMPORTANT NOTE:~~ Must set Z zero at bottom of work if using multiple tools. You can set Z zero at top of work if just engraving with one tool.

* Must set Z zero at bottom of work if using multiple tools. You can set Z zero at top of work if just engraving with one tool or any case where the top stock reference is preserved.

* Must use sacrificial board underneath stock if cutting through stock completely.

1. ~~Check~~ the bed is clear of debris or ~~obstruction~~

1. Brush the bed clear of debris and remove any obstructions for the gantry.

2. Click “Initialize”. This will home the Z, and X-Y axes

2. Click “Initialize”. This will home the Z, X, and Y axes.

3. Attached collar to collet, begin thread to spindle, and insert first tool. Tighten collar with the two spindle wrenches.

3. Insert tool #1.

4. Remove ~~dust~~ ~~collector~~ ~~boot~~ from spindle.

5. Move gantry to back of machine with X & Y keyboard buttons.

⚫

5. Click “Measure tool” (at corner of screen).

6. Position stock squarely onto bed and clamp down. Remember to use sacrificial board underneath stock if cutting through stock completely.

6. Connect touch plate and Click “Touch Top”.

7. Click “Laser On” (it’s not perfect rn, needs alignment).

8. Position laser light over corner of stock. Remember which corner you choose when setting up CAM job.

8. Click “Laser X0 Y0”.

9. Click “Laser X0 Y0”. This will zero tool head over where laser light was initially positioned.

* For ‘Z0 at top’ jobs, plug in touch plate, position under tool and Press “Touch Top” button.

⚫

* For ‘Z0 at bottom’ jobs, Make sure no local Z is set. T codes in job trigger measure tool. Ensure job rapids clear all clamps.

Turn on laser using ‘Laser On/Off’.
