The spindle uses ER25 collets. These eventually wear out, so check before using them. Collets are a durable expendable.
Some people buy their own collets. There are a number of suppliers of collets, nuts, and related accessories. [http://www.techniksusa.com/ Techniks] and [http://www.shars.com/ Shars] are both brands that have been recommended by experienced CNC users, although other brands may also be of equivalent price and quality:

=Status=
June 2020: Keyed switch replaced.
August 2017: Dust collection system out of commission.
June 2017: There is an intermittent break in the wiring for the Z-axis Zero Plate. Check for continuity before using (the #1 input should light up on screen when you touch the contacts together). It usually works near the front of the table, but not halfway back. This will get fixed eventually, but it's a good idea to be in the habit of checking.
12/27/16 - Fixed Shopbot x-axis homing. The cable had been pulled on hard enough that some of the conductors broke inside the cable. It has been spliced, soldered, and heatshrinked back together.
= How to Get Authorized =
'''Authorization for this tool by authorized proctors only.''' This means you cannot get authorized by just anyone who is already authorized. You can only get authorized by a few people, the proctors listed below.
Authorization sessions are scheduled roughly monthly. Check the [https://www.meetup.com/Pumping-Station-One/events/ Meetup calendar] for upcoming authorizations. If no ShopBot sessions are currently scheduled, ask the [[CNC Area Host]] or on the [https://groups.google.com/group/pumping-station-one/ Google Group].
Be aware that this authorization consists of two parts; the first session is a classroom session that will cover the software required and introduce you to the essential settings and chip-load calculation, and the second part, scheduled separately, is a hands-on class.

*Autodesk Fusion 360
**The ShopBot computer does not have this and may not be fast enough to run it.
**You '''MUST''' use the custom post-processor below. Otherwise, you will bypass the safety check to make sure the spindle really is running!
**For local '''Windows''', to install this on your local computer:
***Unzip and install this in C:\Users\YourName\AppData\Roaming\Autodesk\Fusion 360 CAM\Posts
***Note that AppData is often a hidden folder!
***Inside Fusion 360, when you select Actions / Post Process, under Configuration Folder, hit Setup and select Use Personal Posts.
**For local '''Mac'''
*** Unzip and install in Macintosh HD> Users> USERNAME> Autodesk> Fusion 360 CAM> Posts
*** In Fusion 360, when you select Actions > Post Process, under Settings select Personal Posts for the Source
**For '''Cloud'''
*** Open Fusion 360 and navigate to Libraries > Assets in the Data Panel.
*** Double click the Assets > CAMPosts folder to enter it.
*** Use the Upload button to upload the desired post processor from your local machine to the Assets > CAMPosts folder. This will upload the post to the cloud and allow you to access it anywhere you may login to your Fusion 360 account through My Cloud Posts.
*** After enabling cloud libraries in Fusion 360, you will be able to access your cloud post processor library by setting the Configuration Folder (Windows) or Source (Mac) to My Cloud Posts. Both of these dialog boxes are shown below. You will then be able to select the Cloud post you uploaded in the Post Configuration field (Windows) or the Post Processor field (Mac).

== Use checklist ==
PS1 is experimenting with the use of checklists to encourage the safe use and proper care of tools in the workspace. The latest version of the [[checklists]] for this tool is stored as a [https://docs.google.com/document/d/1zxrvQX0DXaLxaXkaKCKpZ-PAgnDak6ezKKBkdu_Fw1U/edit?usp=sharing Google Doc] that can be edited by anyone. If you make changes, update the effective date at the bottom of the document. Print a new copy, and replace the old one.
Physical checklists are necessarily constrained in length. Following is a more extensive pre-flight checklist:
* Did you home the machine?
* Did you home the machine?
* Is the dust collect gate open?

* Is the dust skirt set right so it does not get smashed.

|Created new AutoDesk Fusion 360 Post Processor. Modified Vectric Post Processors.
|Created new Fusion 360 Post Processor. It includes the changes listed below for the Vectric Post Processors. For Vectric, modified the Post Processors so that if the spindle does not spin up, it gives the user a Retry/Cancel dialog box instead of Abort/Retry/Ignore where Ignore is identical to Retry. Also, these Post Processors broke the Preview mode in the ShopBot software because the preview mode did the real spindle check and it failed because, of course, the spindle wasn't running. The new version will ignore the spindle check in preview mode.

|Updated VCarve Post Processor
|Previously, installed new Post Processor to preset an Abort / Retry / Ignore dialog box when the spindle is started but doesn't spin up. Usual culprit is that a job is started when the the interlock is disabled, which results in the non-spinning bit crashing into the workpiece. Abort stops the job. Today, fixed Retry code. If you power on the VFD and the motor start is enabled, the VFD refuses to start. So I've re-programmed the Retry button to stop the VFD, wait 2 seconds, start the VFD, wait 2 more seconds, and check again to see if it is running. The Ignore button actually acts as Retry because we don't want someone clicking through this dialog box and damaging the machine. NOTE: The Aspire PC in the shop also has this Post Processor, but if you use Aspire, VCarve Pro, etc. on your personal computer, you will need the latest Post Processor to support this safety check.

|Updated ShopBot software
|Did upgrade from 3.8.14 to 3.8.26. Installed latest firmware on ShopBot controller. (This was mandatory.) Two features of interest: Fixed occasional erractic behavior after repeated Stops and Resumes (and Nudges or Command Insertions). Reduced liklihood of Keypad lockup.

|Created new VCarve Post Processors
|For drag/engraving bits, it's important that the spindle be turned '''off''' so as to not destroy the bit. Instead of manually modifying the sbp every time to remove the check that the spindle is turned on, I created a couple of new post processors (inches and mm, similar to Ryan's), that explicitly ''turn off'' the spindle. The user is given two opportunities to cancel the job if that is not what he/she wants.

== Outstanding Maintenance Issues ==
=== 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.
=== Limit Switch Issues ===
Every time you start the ShopBot, it resets itself so that the limit switches are disabled! You can turn them on (if memory serves) with the Values -> Input Switch Assignment menu item. Limit switches are really useful - but they need to be enabled. When they are, they will stop manual jogging when the limit is hit (although pressing the key again will let you continue moving the gantry) and they will also stop a running job (but give you the option of ignoring the limits.)
I found a couple more problems when testing all the limits. When I took the gantry to X maximum, the dust collector hose pulled off! I put it back on, but I'm not sure how stable this is. Also, when I originally set the Y maximum and minimum, I wanted as much spindle travel as possible. But it appears that if you're at the Y max and move in the X direction, you can hit the middle support with the dust collector boot. We've got several inches Y travel beyond the nominal 48", so we may want to look into reducing this to clear the supports.
