The | == 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: | |||
* | * Has the spindle warmup routine been run within the past 4 hours, or someone else was using the machine? | ||
* | * 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? | |||
* Are the touch plate and clip returned? | |||
* Is the material properly secured? | |||
* Open the Shopbot spindle control dialog (Tools > Spindle RPM Control) | |||
* 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) | |||
=== Spoilboard! === | |||
Gouging the spoilboard affects all users. It most often happens for two reasons. | |||
# Using the top of your workpiece to set the Z axis and your workpiece height is incorrectly set. Plywood is almost never the exact height specified - 3/4" plywood is .7 inches tall instead of .75 inches tall, for example. | |||
# Bits slipping. Check the collet for embedded sawdust - it can stop the collet from tightening sufficiently. Also, stressing the bit so it vibrates can cause the collet to momentarily and repeatedly lose grip. | |||
A few tracks from the bit grazing the spoilboard is understandable. Gouges are not. | |||
== How to Get Authorized == | |||
[https://canvas.pumpingstationone.org/courses/69 Canvas has a course] to help you get started with 2D CNC (requires login). There are two tiers of classes to be authorized. Both Tier 1 and Tier 2 authorizations can be [https://pumpingstationone.org/events/ found in the calendar]. | |||

'''ShopBot Scheduling Guidelines''' | '''ShopBot Scheduling Guidelines''' | ||
* You must show up within 15 minutes of your start time, or lose your slot. | |||
* Please cancel your slot ASAP if you know you're not going to make it. | |||
* 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. | |||
'''Abuse''' | |||
* The schedule is a privilege. User making a habit of not using their scheduled times, or cancelling last minute are subject to losing privileges. | |||
* Last minute cancellations make it difficult for others to plan ahead. | |||

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, which may be worth it as it helps prevent slips and ruined jobs. 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. | |||
