 +=====  Making a Stencil on the CNC or Laser  =====
 +
 +
 +Load eagle, view the tCream/​bCream layer. I suggest pulling up the DRC and mask , change the min/max of the cream to 0.1mm , the creams will slightly shrink after you hit apply
 +
 +====  CNC  ====
 +For the CNC Mill, export the gerber with the right CAM job, get the GTP/GBP layers and import into PhCNC. as top /bottom stencil.
 +
 +Bond some 3mil brass sheets to a PCB FR4 with spray mount adhesive. Use a drewtronics 30o bit @60000RPM, test cut 4-8mil (7mil) tool tests to make sure the stencil is cut properly.
 +
 +Cut stencil, check with camera. buff with scotchbrite green, remove and use flux remove to gently lift away the brass stencil, do not stress it.
 +
 +
 +====  Laser  ====
 +
 +For the Laser, export the gerber with the HPGL CAM job, get the tCream or bCream layer and import into LaserCut as PLT
