Let us know how you manage with the PID tuning.

I have done 3 machines with CS Labs and it's been hit and miss with all of them.

The first was my Denford. If the settings are 'weak' the machine is slow and cumbersome. If too aggressive I get PID errors although I have found a happy medium.

In all cases I have tried auto PID tuning (the controller, after tuning the drives themselves) but limited success.

Even the manual indicates its better to do manually in most cases.

For another machine I retrofitted, we managed to get a nice speed / rate on the machine but its small and doesnt carry a lot of weight.

With my Concrete machine (Thor), it will be interesting. The design is fixed gantry, Y moves a table of around 100kg and I am looking at speeds of >10m/min using a Panasonic 1.5 KW Servo and very beefy ballscrews.

The drives have an auto tune feature which tunes all the time. How this works in reality, I dont know. I will have the Y running again this weekend, just need to do some alignment and will see what I can get from the machine.

I have a video of the machine doing slow movements of I think 4000mm/min. I have had one servo run away (my own fault, made a mistake in config) and I can confirm that the table can move a metric fuckton faster.
