Drop your acceleration and max speed to half what they are currently and re-test.
I'll try that tomorrow, I know when in helix cutting if the ramp angle is too shallow it doesn't move. I use 0.5-2mm bits and killed 15 so far but most was poor setup by me.
Pha.... Amateurs! Lol.

I'm down to 1x1mm 2fl. 1x1mm 3fl and 1x2mm 3fl so my feeds are usually slower no faster than 190.

IN plunge it seems fine. Its just this drift now any chance it might be software? It's China made and the software isn't genuine it's basically as it come.

Oh my o/s is 64bit mach3 is running in 32bit compatability mode. But with that said on the other system (32bit) 4th axis just spins instead of indexing. It seems to index on the 64bit. But it's very recent like since Friday it started this drift.
