General Counterform Prep

Prepare A New Counterform from 3/4" MDF Stock

	Complete
Clean distribution table, check gasketing and vacuum table hoses.
Check MDF for bubbles and warp
Position 3/4" MDF on table and engage vacuum (.70 pressure minimum, Crown side Up).
Run "CTF Skim" program for appropriate half of table. Start program Z at 0 and run first skim.
Set "skim" operation Z to -1.5 and skim again.
Disengage vacuum, flip piece, re-engage vacuum. Note: Sweeping & Dust Collector is preferred for MDF particles over using standard vac.
Run "CTF Mounting Holes Counterbore" and "CTF Mounting Holes Shank" program for appropriate half of table. Shank program Z should be set to 1 or 0 (whatever is set)
Disengage vacuum, move MDF to edge of table and drill out remaining shank depth with 7/16" Drill Bit. Plane holes from back side to ensure flush seating with table.
Fasten MDF to table starting from middle holes and working out to edges. Note: Fasteners should be snug but not overly tight. Engage vacuum.
Run "CTF Skim" program again for appropriate half of table. Set program Z to depth of last skimming (-1.5mm) and adjust accordingly to remove an additional 1.5mm of (glue layer) material. Final Z depth should be -3mm.

Note:

These conterform preparation passes should be set to Origin Index 0.

The final z offset values (toatal of material depth skimmed, likely 3mm) will be the starting Z value for Origin Index 1 in susequent programs.
