We will be using the PS1 Skedda platform for scheduling ShopBot time.
Click this [https://pumpingstationone.skedda.com/register?key=11373bf&payload=CfDJ8AhWcCKz7g1DjwN6myjap4cdIEdLCUN78whkwElLjg7vhdI_Fm7_PGyoWzpgWFi1yae6LzzqVdM8dC7bNqpUHlonT2HhMFbiBWr5rLkaT2cXgL-GZPhljdRVuCTgnUUd2g link] to sign up or sign in and make a reservation. Select any available time and click the plus button or the green BOOK button to reserve your time on the machine.
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 ===
=== 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.
