TOS-KURIM CNC Upgrade

[JimJam]

I finally got another chance to play with the mill, with no success at all so far!

The more I mess with tuning the more I realise I have no idea what I'm doing!

When you say unstable, I assume you are referring to the visual display on the servoconfig software displaying any line that is not a straight one?

I am a bit unsure of the actual shape of the plot I should be looking for as well, from what I've researched on the subject it should be a square up and back down kind of thing?

I have attached a screenshot of the settings I have currently, which I believe are not correct at all but this is the only combination I got to that doesn't result in the motor oscillating back and forward.
