Stumped on this one. Any suggestions? Using Vcarve Aspire, exporting to correct machine type. Using Carbide Motion to run Shapeoko 5 Pro (2x4).
Simple pocket. Everything starts fine, but later in run, the Z-axis will begin to drift downward, cutting deeper than designed. See fine steps downward near outside edge of pocket.
No loose bolts. Z is zeroed correctly. This happened on several pieces initially, until I quit using Bitsetter. It stopped, now it is occurring again.
Been in CNC for five years and never happened on my old machine (Bob’s CNC).
