If you are still there (!) I’ve noticed that -
.
1) You are running Mach 3 from a PC
2) You always use your phone to post on the forum
Does this mean you do not have easy access to the internet on your PC therefore cannot read the Mach3 manual? It is quite a large pdf document and one which would not be fun to read on your phone.

If this is the case, I’m sure someone could paste out the motor tuning part of the manual as text into a reply post. This would show you exactly what you need to do. I’m away from my home PC so cannot do it right now.
