 +======= Startup ========== 
 +  * With the power disconnected,​ clear all non essential material from the CNC working area. 
 +  * Connect power. 
 +  * Open the front door of the CNC cabinet to access the keyboard, mouse, axis power and PC power. 
 +  * Make sure axis power is set to off. 
 +  * Turn on the PC. 
 +  * login: ''​vhs''​ 
 +  * password: ''​vhs''​ 
 +  * Start LinxCNC 
 +  * Make sure the big red Emergency stop button is off (pulled out). 
 +  * Enable the axis power. 
 +  * verify that there are no loose wires and the machine appears to be in good working order 
 +  * handle any warning messages that LinuxCNC reports. 
 +  * Proceed with prep and cut. 
-__Description:​__+======= Shut down ==========
-The drill press comes in a floor or bench-mounted model. It has a motor driven head that has a chuck that accepts bits or cutters. It also has an adjustable table on which the work is mounted. It is operated by pulling a rotary lever that lowers the drill bit into the material. To avoid accidents, the following operational safety rules must be observed by everyone working on the Vancouver Hack Space drill pressFailure to follow ​the safety rules may result in a loss of shop privileges.+  * Quit LinuxCNC 
 +  * Disable axis power 
 +  * Logout of linux with the "​shutdown"​ option 
 +  * Wait for all systems to turn off 
 +  * Disconnect CNC 
 +  * Stow keyboard, mouseand extension cord in CNC 
 +  * Remove your tool(s) from the chuck. 
 +  * Clean up the cutting leftovers The next user thanks you!
-__Start With A Risk Assessment To Ensure A Safe Work Area:__ +====== Notes for later======
-  - A two foot perimeter around the drill press should be kept clear of people, debris and sawdust that impair traction or footing to avoid slips and falls. +
-  - Safety glasses with side shields or a face shield must be worn. Hearing protection should be worn. +
-  - Remove loose fitting clothing, jewelry, and tie back long hair. +
-  - Give the work your undivided attention. +
-  - Do not wear gloves or anything that would allow a hand, fingers or clothing to be wrapped around the revolving bit.+
-__Operational Safety Rules:__ +  ​Machine zero, work zero and G28:​watch?​v=J3gN5wqz2FE 
-  ​Approach your work at VHS and on the drill press with a safe attitude! +  - http://​​wiki/​4_Axis_TB6560_CNC_Stepper_Motor_Driver_Board_Controller 
-  - Make all drill press adjustments with the power shut off. +4 Axis TB6560 Controller board 
-  - Keep all guards and covers on the machine when it is on and running+  - We have collets ​for 3mm, 4mm, 6mm and 1/​8”, ​3/16”, 1/4" shank end mills
-  - Make sure the size of the bit is equal to or less than the capacity of the drill press+  - We have [[http://​​|step block hold down set]], a [[http://​​|milling vice]] ​and a set of extra [[http://​​|T-nuts]] to clamp your work. 
-  - Do not exceed the recommended speeds ​for the type and size of drill bit being used or composition of the stock being drilled. +  - The upper e-stop button ​should ​work, but verify that it stops the mill before you begin any real operation.
-  - Center punch the drill-hole location into the stock. +
-  - Insert bit into drill chuck and tighten with the chuck key. REMOVE CHUCK KEY FROM THE DRILL CHUCK BEFORE STARTING THE DRILL PRESS +
-  - Use a clamp or vise to securely fasten the stock to the drill press table. Never attempt to handhold stock less than 3’ long while drilling. +
-  - Drill into cylindrical stock using a “V” block. +
-  - Long stock should be drilled with the excess to the left of the operator. If the stock rotates it will hit the drill press columnnot the operator+
-  - Support the underside of the stock to be drilled with backer board secured to the drill press tableDO NOT DRILL INTO THE DRILL PRESS’ TABLE, except for the existing hole in the centre of the drill press table! +
-  ​Never start the machine without the table clear of everything except the stock you are drilling. +
-  ​Keep hands and fingers at least 3” from rotating drill bits. +
-  ​When drilling deep holesfrequently raise the drill bit from the hole and use chip brush to remove cuttings and allow the cool bit to cool down. +
-  ​When you begin to break through the underside of the stock, ease up on the feed as to not tear the material from the undersideIn addition breaking through too quickly may cause the stock to pulled up the drill bit and off the table +
-  ​If a drill bit binds, turn off the drill press and carefully turn drill chuck backwards by hand to free the drill bit. +
-  - Never reach around or under rotating drill bit or grab the chuck to stop a drill pressThis can result in hand puncture or other serious injury. +
-  ​Turn the drill press off before looking up or walking away from the machine. +
-  ​Never stop the rotation of the drill chuck, spindle, or uncontrolled stock rotation when jammed on the bit with your hands or fingers. +
-  ​Don’t touch the drill bit and shavings since they are hot immediately after drilling. +
-  ​Always clean the work area in the machine upon completion of the milling task. Do not use your hands or blow the shavings, use a chip brush+
-  - When milling into metal use a coolant oil (WD-40 often works well) and use the appropriate speeds and feeds. Rags or chip brushes saturated with cutting oil should ​be disposed of in a fire can or outside in the dumpsterNever place oil saturated material in the interior garbage cans within the space!+
