Hello! Recently I finished building my router, it uses a Dremel 3000, Nema 17 motors, Arduino UNO, and A4988 drivers with a cooling fan. I am making my cutting programs with Vectric and run them with GRBL. The issue I am observing, is that after a couple of cuts, my router starts cutting out of place, for example, it cuts some holes in the right place, moves to the next position and the place where it plunges is out of place i.e the final part is not correct. I have been playing a while with accelerations (my leadscrews advance 2mm per rev, and acceleration is currently at 18 mm/s^2) trying to fine tune the machine but I havent reached the sweet spot yet, any siggestions are highly appreciated.
