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.
