Need some help/ideas here on what could be going on with my machine...out of the blue it started messing up cuts in one axis for some reason. Image attached you can see where those notches are(using an 1/8" endmill)...they should all line up...after each operation its off by almost an 1/8". This is code i've cut with no problem just a couple days ago...absolutely nothing changed in gcode or mach...so what could be happening? Mechanically checked everything was bolted tight..nothing loose??? something wrong with the stepper? something going on in Mach? Gecko 540 driver?? no idea....
