Authorization Checklist
This is here as a checklist for proctors to follow when authorizing people. It can also help remind you of things after you are authorized. Just reading this does not authorizing you.
- How to get authorized
- Watch the meetup group for a recurring class on the second Thursday and last Sunday of the month. Sometimes check the forum for announcements or ask on the forum if no announcements have been made for a few weeks.
- Authorization group size
- There is no cap to the software instruction preceding the machine usage portion of the class. If you come to this portion it is easier to get fully authorized at a later date.
- 3 machine users - each person will run a job (~1/2 hr each) and everyone will assist each other in completing a job profile and pocket cut. You must be present for the entire authorization
- Safety
- Safety Glasses
- Hearing Protection
- Dust Protection
- What can go wrong (and what to do)
- How does machine work
- Axes
- Motors
- Spindle
- Daily Maintenance
- Spindle bearing warm up.
- The "C5" warm up routine should be run on the first job of the day. It runs the spindle at 3 speeds for 3 minutes each to warm up the bearings. (When it doubt, warm it up)
- Spindle bearing warm up.
- Extended Maintenance
- See maintenance schedule file under documentation.
- Grease the racks
- Use Grease type: Manual states any type is safe there is some in the draw
- Machine Control
- Turn on sequence
- Log into computer
- Turn on Shopbot big red and yellow twist switch (see zeroing below)
- Insert Key and turn to "engaged" position.
- The VDF should light up, the spindle fan should be on.
- Start "Shopbot 3" program.
- Open Tools...Spindle RPM Control menu (to allow RPM control)
- Make sure collet is tightened or no tool or nut is installed
- Run the C5 warm up routine
- Jogging
- Keypad
- Arrow Keys + Page Up, Page Down (ctrl for fast jog)
- Turn on sequence
- CAM Software
- Vectric V Carve
- Just the basics...separate class for advanced V Carve.
- Online videos
- Running your Job
- Zeroing X & Y
- With machine off slow push gantry towards X0 until it hits hard stops (optional)
- Turn on big red switch while still holding gantry.
- Jog machine away from X0 Y0 so machine will find switches
- Click X, Y zero button.
- Zeroing Z (top of work piece)
- Jog over your work piece
- Place Z zero plate on work piece under the bit
- Place clip on bit
- Test connection by touching plate to bit and watch for light #1 to light
- Click the Z 0 button (it will touch off twice!!!)
- If Z is critical, you may want to verify that your bit has been zeroed properly by using a "MZ,0" command over the surface you have zeroed the bit to. Repeat zeroing if not correct.
- Zeroing X & Y
- Waste Board and clamping
- Collets, Bits, Feeds and Speeds
- Feeds and Speeds
- Use a Cut Load Calculator to determine which feeds and speeds you should be using for your specific bits. An overview is avaialble at: [1]
- Collets
- We currently have collets for 1/2, 1/4, 3/16 and 1/8" shank bits.
- Try to keep them clean and store them away from dust between uses. Dust between the gaps will produce runout. The drawer mounted under the Shopbot is the right place to store these items.
- If the collet nuts are not threading smoothly try cleaning the threads with a small brush, spindle threads as well.
- Bits
- Use bits designed for the material you are cutting. Don't just steal a bits from the Bridgeport. They won't do a good job and will probably overheat.
- For cutting out things, use the smallest appropriate bit. Using a 1/2" bit to cutout will just create a lot of mess.
- Feeds and Speeds
- ShopBot should not be used for...
- Metals other than aluminum
- Cutting anything that requires coolant or lubricant (it will ruin the waste board)
- Ripping lumber (use the table saw)
- Thickness Planning (Use the planner if you can)
- Drilling holes with drill bits (a small end mill works better)
- How to leave the machine (be excellent)
- Machine
- Home the machine to X0, Y0
- Turn off both switches
- Remove Key
- Remove bit and collet.
- Place both collet wrenches on top of electronics box
- clean up work area
- Smooth out waste board if you puckered it at all.
- Check if the dust collector needs to be emptied
- Machine
- Post a picture on our Blog please!
Pre-Flight Checklist
- Did you home the machine?
- Is the dust collect gate open?
- Are you sure you have the right X, Y orientation for your file and material?
- Did you set the proper X,Y zero for your work piece on the Shopbot.
- Is the correct bit installed and tight?
- Is the key in and turned on?
- Is the dust skirt set right so it does not get smashed.
- Is Z zero set to the work top?
- Is the touch plate and clip returned.
- Is the material properly secured
- Safety glasses, hearing protection on.
- Start the job with the E-Stop ready to hit.
- Turn on dust collector ( I like to wait so I can hear that things sound right on the shopbot before turning on the collector)

Maintenance
Maintenance Log
| Date | Preformed by | Service Type | Notes |
|---|---|---|---|
| 11/8/2014 | Ryan Pierce | 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. |
| 11/8/2014 | Ryan Pierce | 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. |
| 5/31/2015 | Ron Olson | 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.
Automatic Dust Collection
The ShopBot has +5V TTL outputs that could be used to trigger automatic dust collection (when the spindle goes live) and/or a warning light (when the gantry is enabled to move.)
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.
