I am going to be doing a bunch of etching that all has to be the same depth. The problem is in the lowering the spindle to the exact same height for each print. Right now I am just using the thin paper method. And its not the most consistent.
After each etch is finished the spindle raises up an amount and then retracts to the starting position. It would be super useful to know that exact amount of mm the spindle raises up before it returns to the start point so that I know exactly how much to lower it again so the next etch gets the same depth.
Any thoughts on the best way to figure that out? Or does anyone know that already?
