+    * For your first project, you must discuss your project plan with a CNC committee member who is currently offering training.

 ===== Basic Reminders =====
-  * Must wipe the vice before clamping. Chips between metal cause dimension errors.
+  * Sign in on the log book before you start working!
+  * If you're a committee member and modifying the machine, check and update Jaxen's homepage!
+  * Wipe the vice before clamping. Chips between metal cause dimension errors.
   * Wipe calipers before measuring. Same reason.
-  * Tap the stock into the vice- must be resting on parallels- this eliminates "vice-lift".
+  * Tap the workpiece into the vice- must be resting on parallels- this eliminates "vice-lift" (Jaxen's vice is pretty resistant to this, but it's still good practice).
   * Don't let the cutter bit fall out! Remember the 3 points you must touch while doing this. Refer to training.
   * Chip control- don't cut chips. Chips dulls bits and scratch your surface finish. Get them out of the path of the bit somehow (coolant to be added).

 Identify the flattest faces to use as clamping faces, then face the roughest first.
 Next, put this newly faced face against the jaws, and face the next face, 90* from the first.

 If you climb-cut a face around the edges, it won't produce a burr, because the burr is sucked inwards and naturally cut off.

 You will definitely need a custom mount for your part if:
-  * Less than 2 parallel faces of your finished part are stock
+  * Your part does not have at least 2 parallel faces that are rigid enough to be load bearing.
 The standard mounting method currently is M6 threaded holes spaced 10mm apart, passing through non-threaded holes in your workpiece.

 **Steps:**
   - During your operation, click CYCLE STOP when you are just at the boundary of 2 lines of G-Code operating. Doesn't matter whether you're at the end of one or beginning of the one you want to resume in.
-  - Do whatever you need while the machine is paused. Move workholding, manually jog the machine, adjust workspace origin, etc.
+  - Do whatever you need while the machine is paused. Move workholding/workpiece, or manually jog the machine.
+    - HOWEVER: be careful of executing G-Code in this state! Your program may be depending on mode G90 or G91, and any other settings, and won't know if you change them!
   - Jog the machine back to the start of where you want to resume.
   - Scroll in the GCode window to highlight the line and feature you want to resume at the start of.

+    Temp job log notes:
+Climb cutting even for side-milling makes a noticable difference. Always climb cut side faces.
+Sep 6 facing steel plate. Should be all same specs as before, but this time plate is flat, so depth is even across whole operation.
+rpm, 30mm/min.
+No lip between passes!
+nd half: switched to 1400 rpm
+result: no visible difference, may cause finish to change faster
+observations between climb and conventional: there may be a relationship to the time into the pass. The circular swirl pattern gets more significant later on during the pass, maybe due to buildup of chips.
+The actual left/right side of pass does not seem to matter- the overlap of the swirl pattern appears to be due to minor changes in surface height.
+Making passes in the same direction each time does seem like it would provide better finish.
