Starting the Websaw
Bleed water from the regulator and check that the oil reservoir has oil.
Check that you have operational air pressure on your regulator. The normal operational range for the
saw is 60 to 80 PSI.
Check that the air filter is clean.
Switch on the main power disconnect (make sure both switches are turned on).
Wait for computer to boot up and open the Websaw software (located on desktop called “Websaw”).

Websaw Overview
Feed rollers
Infeed and outfeed rollers are used to move wood through the Websaw.
It is important they have firm tension on the wood and if needed tension pressure can be adjusted.
Proximity photo sensor (M120)
The proximity photo sensor (or eye) is used to detect a board entering the Websaw. Once it detects
the board the proximity sensor triggers the Websaw software to start “autocycle”. The photo sensor
sensitivity is fully adjustable with a small screwdriver.
Vertical limit sensors (Up M54 down M53)
The saw carriage has two proximity sensors for determining the location of the saw head.
If the saw carriage is up the top proximity sensor is tripped and the Websaw software will show this
on the front screen as “Saw Carriage Up”. Conversely if the saw carriage is down the proximity
switch will be trigged causing Websaw software to indicate “Saw Carriage Down”. The only other
position the Websaw software will read is “Saw Carriage Middle” when neither of the proximity
switches are triggered.

Pivot head angle and limit switches
Three pivot head switches control the pivot home position, and over rotation protection.
Homing proximity switch (M322)
When the saw head homes it looks for a known location by using the homing proximity switch. Note
that if this switch moves your 90 degree angles will be off according to the amount the proximity
switch moved. Make sure it stays tight!
Overtravel proximity switch (M321)
If the saw head starts to over rotate this switch will stop the software from going beyond the saws
operational range.
Mechanical overtravel switch (M12)
When all else fails this switch will stop the saw from over rotating by bypassing the software as a
last resort.
Motion Control
The TCT Websaw has two computers used for controlling the saw. One computer is a standard
PC running Microsoft Windows 98. In addition to this a second computer called a “PMAC”
controller is located inside the PC. PMAC is a 16bit computer running a real time OS for all
motion control.

Printer
The Websaw uses a Matthews Jet A Mark ©printer for printing on each board. The printer consists
of a three parts. The pump, control unit, and print head.
Note that the LCD readout must be set to “00”. If you press the “text” button and the LCD screen
reads anything other then “00” keep pressing the “text” button until the LCD is back on “00”.
Note the print head must be cleaned at least daily and if the printer is being shutdown for 2 or more
days the line must be bleed with cleaner fluid (see “Printer” page 13 for more details).

Websaw Software
The Websaw software is a Windows application that provides an interface for the operator of the
Websaw. When upgrading the Websaw software both the PMAC microcode and Websaw software
must be kept up to latest versions (see software upgrade for additional details).
The above operator screen allows for quick and easy operation of the Websaw.
Within the Websaw software under “Input / Output” you can view what PMAC PLCs that are
running and check the status of various sensors. This screen is primarily used to troubleshoot
problems. For an complete explanation of each option see “Websaw Software”.

The “Motor Data” screen allows for quickly checking that each motor is responding and has not
jammed.
From within the “Cycle Status” screen all the software settings for the Websaw are easily calibrated.
See “Calibrating the Websaw” for additional details.
For additional details on the Websaw software see “Websaw software”.

Websaw Maintenance
Feed Rollers
The Websaw feed rollers must be at least cleaned daily to allow for reliable traction on lumber. We
recommend using a steel brush with denatured alcohol for best results.
Print head cleaning
Remove the print head and using a small brush gently wipe away any ink and saw dust build up on
the print head. Dip your brush into the supplied Matthew’s thinner solution to help remove the gum
build up. Note if the printer is shutdown for two or more days it is necessary to bleed the line of ink.
See “Printer” page 13 for more details.
Air Pressure
Adjust air pressure to 80PSI. If “banging” occurs reduce air pressure. Air pressure operational range
is from 60 to 80 PSI and must not deviate more then 10 PSI while running. Note the minium
recommended air hose is 3/4 of an inch.

Pneumatics
Keep oil reservoir supplied with approved pneumatic oil. Adjust pneumatic oil flow to last
between 2-3 weeks.
Roller Conveyor
Maintain 1-1/4 inch parallel adjustment between the feed rollers and the conveyor. This is an
average figure and may need to differ depending on your wood thickness. Adjust as necessary to
maintain positive traction at all times on lumber. Typically maintain slightly more traction on the
infeed side then the outfeed side.
Saw Motor
Grease approximately every 500 hours being carful not to over grease. The saw blade nut is right
hand thread. Make sure and only used approved wrench when tightening and apply a light amount of
oil to threads before tightening.
