+Status: draft

+Outline:
+
+    - Hardware Notes:
+        - worthless side shields on 3018ProVer
+        - limit switches seem mandatory for candle
+    - Software Chain Notes:
+        - talk about final pcb2gcode settings that work
+        - grbl:
+            - gcode reference: https://linuxcnc.org/docs/html/gcode/g-code.html
+            - quick reference: https://linuxcnc.org/docs/html/gcode.html
+            - https://github.com/gnea/grbl/wiki
+        - candle2:
+            - losing work coordinates
+            - G28 and G28.1 grbl commands
+                - turn off command autocomplete when using G28.1 :(
+            - set coordinate system to work size
+            - z-height probing w/ interpolation
+                - don't forget to apply the map :/
+                - don't forget to save the map, gets lost when switching jobs
+            - adjust cutting depth if needed using the coord system z-offset
+            - don't use pendant while controlling with PC!
+    - Physical Setup Notes:
+        - double-sided tape
+        - spoilboard
+        - apply soldermask before drilling to avoid painting leaking through holes!
+        - using multiple sheet to spread solder-mask
+        - clean surface!
+        - uv-curing ~5-10min depending on lighting and thickness
