Hey Sebastian,
the Onefinity CNC machines are gantry-style machines. The first step must always be 1. ensure your machine is accurately rectangular (“square”) and coplanar (“not twisted”). Step 2 is flattening the wasteboard and adjusting perpendicularity of motor axis to machine bed (“tramming”) is only step 3+4.
So, have you first
Step 1:
- Ensured that your machine is accurately rectangular (“squared”) (-> comparing diagonals method) and coplanar (“not twisted”) → fishing line method)?
Step 2
- Surface wasteboard
Step 3:
Step 4:
Yes, spindle axis is less perpendicular to machine bed on one side (more “out of tram”). Front-to-Back Tramming can be adjusted separately at each X axis end. See “Tramming” above, but conserve order of proceeding. First step, prior to tramming and surfacing, should always be ensuring a machine with coplanarity adjusted (“not twisted”).
Coplanarity (“not being twisted”) means that all four machine’s feet are in one geometrical plane. You adjust it by altering the height of one machine foot (three feet are always in one plane (table with three legs can not wobble) e.g. with Any Surface Leveling System Feet of QCW frame or with height-adjustable Casters under the table’s feet. Crossing fishing lines method to adjust it works well).
