Was doing a router job in birch ply a few days ago and it was cutting multiple identical pieces from the sheet. I started the first piece and did not use my shopvac as I was too busy watching the cut. That cut went well. Started the second cut… turn on the vacuum… then everything went strange. The router would veer off then come back and I did not put 2 and 2 together until later on that my vacuum must have some how been introducing interference in the wires of the steppers.
Has anyone else experienced something like this and did you just move your vacuum further away?
