Exhaust Plenum Cleaning
• Power system OFF.
• Remove the Z-axis table.
• Remove the two thumbscrews.
• Lift the Plenum straight up, off of the hooks, and
out of the system.
• Clean the Plenum and inside the Laser System.
• Installation is opposite of removal. Make sure that the Plenum rests on the hooks.
Adjustments and Lubrication
There are no periodic adjustments required. The bearings in the motion system will self adjust
to take up any clearances as they begin to wear. The belts are fiber reinforced and will not
stretch under normal use so that periodic tension adjustment is not necessary. Optical
alignment is not necessary because the laser and the #2 Mirror are fixed.
All bearings in the system are sealed and do not require lubrication. DO NOT lubricate the
tracks that the bearings ride in. The only lubrication that may be required is the screw threads
for the table lifting mechanism. After some time, contaminants can adhere to the lubricant,
which can cause the engraving table to bind up or sound squeaky. If this is the case, wipe off
the contaminated grease with a soft cloth and apply fresh white lithium grease to the screw
threads. Run the table up and down to work in the fresh grease.
Electronic Upgrading
The laser systems onboard computer is equipped with a special “Flash” upgrade technology. If
the electronic operation of the system should ever require upgrading, it can be done
electronically without the changing of any parts. The upgrade file gets downloaded from your
computer to the laser system via the parallel port. This file is then run on the laser system and it
only takes a few minutes. Once the file has completely run, the laser system will automatically
restart and the new changes will take effect. For more specific details, please refer to the
instructions that will accompany the flash disk.
