Tramming the Wolfpawn 4040 Pro Spindle to the Bed

Tramming the Wolfpawn 4040 Pro Spindle to the Bed Tramming means making the spindle perpendicular to the bed. An untrammed machine leaves scallop marks on surfacing passes and produces angled walls on vertical cuts. How to Check Tramming Quick Check — Paper Method 1. Mount a straight rod or dowel in the collet (or use a drill bit with tip cut off) 2. Lower to just above the bed 3. Rotate the spindle/router body by hand 180° 4. Check if the rod tip is at the same height at both 12 o'clock and 6 o'clock positions 5. Check 9 o'clock and 3 o'clock (X axis) Accurate Check — Dial Indicator Mount a dial indicator in the collet on an arm. Rotate manually around the Z axis and read deviation at each quadrant. Acceptable tolerance: < 0.05 mm across the swing diameter. How to Adjust The Wolfpawn's spindle mount typically allows adjustment by: 1. Loosening the spindle clamp bolts slightly 2. Inserting thin shims (aluminum foil strips) behind the mount 3. Tightening while holding position 4. Re-checking X-axis tram (side-to-side): Shim one side of the spindle mount Y-axis tram (front-to-back): Shim the top or bottom of the mount, or adjust the gantry squareness After Tramming — Resurface After tramming, resurface the spoilboard. It was cut when the machine was out of tram, so it's angled now. A fresh surface referenced to the new tram gives accurate Z depth. How Often to Check After any crash or unexpected hard contact After moving the machine When surfacing passes leave visible ridges When vertical walls show obvious angle
