The Speedy 300 is professional version of the Rayjet 300, the education machine that the Edge has had since 2015. It is difficult to find a direct comparison in the literature but anecdotal research 2) yields:

  • Speedy 300 is faster
  • Speedy 300, 360 & 400 Can have a 'harsh environment kit' fitted - meaning a more sealed in cutting area.
  • Speedy 300 uses JobControl - Rayjet 300 used Rayet Minimanager

Other than these points they appear to be functionally and physically very similar. The biggest advantage with the Speedy 300 is the Job Control software which apart from a range of things allows the user to adjust the duty cycle of the laser firing.

The Laser mark is not showing up in your display? The Laser is probably not switched on yet. Switch the Speedy 300 on in the upper back corner of the cab and close the class so the machine can run thru its startup (zeroing) sequence.

STEP 5. Select the material you are cutting from the Edge Material Folder in the tree structure.

In this case we are looking at the settings for 3mm corrugated cardboard.

Next check the Process that will run for each colour.

The default settings for Black is to Etch and Red is set to cut, check the power settings against laminated power settings table on laser computer desk.

Note that Black and Red are locked as default. See Fabrication Lab supervisor if you need to adjust these settings or add other colours/processes.

After you have done checked all these settings click Ok - Job Control is now ready to cut and etch your job

STEP 6. Now Select the part your want to cut and click the Calculate Update button to show the approximate Production Time (cutting and etching time) to ensure you have enough time to complete your job within your booking bracket.


Prep the Laser to Cut/Etch your Job

STEP 1. Check when the lens and mirror was last checked. if it was more that 2hours ask for the FL supervisor to check its clean and ready to cut efficiently.

A dirty lense or mirror affects the strength of the light cutting your work which will impact on the quality of your job.

STEP 2. Check that the Laser bed is clear of debris

Debris can catch fire!

and that the Honeycomb bed is located on its stops. [Photo]

STEP 3. Place material on honeycomb bed making sure it is located securely in the top left hand corner. [Photo]

STEP 4. Set focal height using calibration tool [Photo]

Place the Calibration tool on the laser head assembly

Using the Z Axis jog buttons gradually bring the honey comb bed up to touch the calibration tool

Lack of attention can result in a HEAD CRASH! at this point. Always take great care when adjusting the Z axis!

STEP 5. Replace calibration tool in its home and close the glass lid

The Calibration tool is a factory matched set with the lens. Loss of the calibration tool necessitates replacing this expensive optic component also.

SO PLEASE MAKE SURE YOU PUT THIS BACK WHEN YOU ARE FINISHED USING IT

STEP 6. Ask FL Supervisor to check your settings.

Failure to have FL Supervisor check setting may result in the member's Booking privileges being suspended. See Laser Cutter Preflight Checks - Supervisor Check.

STEP 7. Push Enter to start job.

The Speedy 300 will etch black portions of the artwork first by default

. .

And then cut Hairline paths set to RGB red 255.

Monitor your job, do not walk away from the machine when job is running. if you need to move away, pause the job by pressing pause .

In event of fire, head crash or other catastrophic failure lift glass lid to abort job and call supervisor over immediately.

Any time that a job is aborted (lifting the glass lid) the machine may be out of zero. Always restart the laser after aborting a job to avoid causing a head crash.

If job is not progressing as expect or the machine is making a strange noise or excessive smoke pause job by pressing pause and call Supervisor over to assess.
