I thought I did enough testing to finally engrave this grid on my Lowrider table, but I was wrong. The grid is 1” squares and is basically the usable area of my gantry, about 34”x56”.
The gcode was done in Fusion and all the tests I’ve done have produced great cuts when working in a small area, about 8”x8”. I’ve even had the machine start cutting on one end, run the full length of the table and then return to complete the cut to test the accuracy.
My question is, what is the first thing you would check if your parallel lines were not coming out straight?
