Thor, or should that be Zeus?

Thor's Z Axis is alive. Short vid of it running on my very wonky table at 5000mm/min - 25mm cycles via the PID tuner. No tuning has taken place yet, Ill do this once mounted and limit switches have been installed.

Lol, sorry.

No offence meant Chaz. I hadn't realised myself why some videos were like that until I happened to trip over that explanation

Thanks for that Andrew, I hadn't realised this until I just read your post!
I thought videos displayed in three vertical stripes like that were simply some new technological fad intended to irritate some of us old farts! Lol
Maybe people shooting vertical videos are often unaware of this, I certainly would have been.
Let's hope the manufacturers improve their default settings to mostly phase out this mode of recording.

I need to order cable for limit switches (3 core for Proxy) and then 4 core for the Spindle / Earth.

Do I need either of these cables to be shielded? 3 Core cable is common, shielding adds a fair bit to the price. I dont mind paying if its absolutely needed however no point if its just a 'nice to have'.

Any suggestions for cable for the 4KW type Chinese spindles?

Thanks

Personalty I would use 4 core cy cable 1.5mm for the spindle

Looking good, try tuning manually - adjust the I & D values, there are documents online about doing this but its also in the CS-LABS booklet. The delay between reverse is a homing error - its not settling at at the zero point fast enough you should see the numbers very slowly retuning to zero and then the green LED comes on in the tuning page. Tweak the values and you should see following error drop and the cycle time rise - in the end it will be going bang-bang-bang one way then instantly the other. You need fast homing (return to zero) and not a slow creep.

The auto-tune is pretty pants really, always tune with the final load, rough tuning is fine for tests but when finished and assembled tune again with all load attached.

Thanks. Ye, its dwelling too long before it finds 0 / Green LED. Playing with the values will improved that. Ill sort that out once its mounted properly and I have limit switches to stop a run away / something going wrong.

The Panasonic drives also offer a lot of tuning. I am not sure how the CS Labs and Panasonic tuning will go exist. Ill likely set the drive to be on a mild auto tune and then use the CS Labs for the overall tuning.

Very curious too to understand how the setup can deal with inertia / whiplash. I refer to demos where they move something that has a ball on a stick and tune the drive that basically shows no 'pendulum' effect when the device stops and starts in different directions.
