 +
The guidelines are as below and only those who are fully authorized may access the scheduler.
 +
 
 +
 
 +
'''ShopBot Scheduling Guidelines'''
 +
 
 +
-Reservations can be made from 2 weeks out to 12 hours before the time you would like to schedule.
 +
 
 +
-No unreserved use.
 +
 
 +
-Please account for clean-up time in your reservation and be considerate of others when scheduling as there is no current time length limit for reservations.
 +
 
 +
-If you finish your time early, end your appointment so others know the machine is free.

=== Lack of True E-Stop ===
 
As shipped, the ShopBot PRS does not support an Emergency Stop. This could be hacked, but it runs the risk of damaging the machine if engaged in a non-emergency situation. Suggested solution: Installing a 10A double pole 24V coil DIN mount relay, and powering the coil via the 24V supply through a normally closed E-Stop button. One pole will disconnect the 63V stepper motor current. One pole will break the control signal that enables the VFD and will cause the VFD to brake to a stop.
