-However, even though you have requested one, it is possible that none of these times will work for our trainers (we’re students, too!). If this is the case, we will try to email you to find another time. Please note that there are no checkoffs during the last week of Hive open hours.+

-Can I bring my own design to fabricate instead of the training board for my checkoff? +**I didn’t get a checkoff scheduled and all of my requested dates have passed. What now?**\\ 
-Probably not. It is, however, at the discretion of your trainer. If the board is small, simple, and on FR4/FR5, (i.e. very similar to the training board), then it might be fine. However, large boards can take over an hour and a half to laser etch just one side. Since most boards are larger than the training one, you will likely have to stick with the training board. It will be easier for everyone (especially if it fails), and afterwards you can simply schedule time on the tools to fabricate whatever you’d like.+Due to the large volume of checkoff requests, we are not able to schedule every checkoff on the first request.

PIs have the authority to cancel any unattended boards.+Yes! You must be present for the entire process. This is for safety reasons. PIs have the authority to cancel any unattended boards. You may, however, leave the space //if and only if// you leave a note with a phone number and accept the possibility that something may happen to your product while you're gone (because PIs are not watching your process).

 +**Can I somehow reserve time on the equipment?**\\ 
 +Yes! Although you are not required to, we //highly// recommend that you do as it guarantees equipment priority. You may reserve time up to 96 hours in advance though SUMS. See the SUMS Guide for more details.

 +  - On the main page, locate the Schedule section. Under the drop-down menu that says, “My Schedule - Select a tool to schedule time”, select the tool in question. Note that you cannot reserve time on a tool until you have completed training for it. 
 +  - Click and drag on the calendar itself to reserve time. Release the mouse button to bring up the reservation screen. You must enter a description in order to reserve time! Click “Save” to save the reservation.
  
-Can I somehow reserve time on the equipment? +We highly advise you to schedule time on all the tools you’ll need, i.e. if you’re fabricating a standard board, you should reserve time on both the Plotter and the Laser. If you do not, and someone schedules time on only the laser, they have priority on the tool.

 It depends on the size and layout of your board. A small board with no electroplating (i.e. no vias) can easily be made in under an hour, while a very large board with lots of copper removed can take over 4 hours not including electroplating. It depends on the size and layout of your board.
