Step A4: Check / adjust vertical bearings
The smooth motion of the Torchmate 2x4 Growth Series CNC Cutting System gantry is managed by the four
vertical bearings that carry the gantry’s weight. In this step you check the gantry’s clearance above the side
rails and adjust its height, if necessary, by moving the vertical bearings.

• Measure the front and back clearances between each gantry end and the rails (four total
measurements).
• A clearance of approximately
1
⁄
8
" is desired.
• Hint: The thickness of a new penny and a new dime (0.114 in.) or two new pennies
(0.122 in.) is a good beginning clearance.
• Loosen and adjust each vertical bearing, as necessary, to achieve an equal clearance of
approximately
1
⁄
8
" at each location.
• Tighten the vertical bearings fully.
• Note: the vertical bearings may require further adjustment in a later step.
