Im trying to joint boards and having a rather strange issue. The wood im using is 3/4 inch clear white mine, not bowed or cupped. Using masking tape on the brass roller side. The boards are 5.5 inches wide by 31 inches long. Machine has been recently calibrated, has correct head pressure new Z pack and cabels, new X encoder. Machine carves projects fine.
When jointing, the machine runs along the board \removing about 1/16 inch of material until it gets about 27 inches along the board, then it backs away from the board leaving about a 1/32 inch "hump" in the cut. Obviously not satisfactory for jointing. It does this every time in approximately the same place. Ive checked everything I can think of...... bearings are all tight, using the rock chuck with a brand new 3/8 inch straight bit. Cant think of anything else to try....... Looking for your ideas.
