Thor, or should that be Zeus?

I am here watching also, not much to comment because of lack of experience and also because I am speechless.

Ditto to that comment! Following your thread with interest, thanks Chaz, please keep the posts coming.

Whilst some of the detail is sometimes beyond me (on all threads), the photographs make sense to me.

That's looking a bit of a beast Chaz!

Gary, thanks as always. I've not been able to get the serial comms working and even though I've tuned the drives manually, I am uncertain if the value it pops out after auto tuning is actually used.

I had also tuned them with no load which is incorrect but I'll realpolitik at that.

you just need to have an RS232 connection to use the servo software, without Rs232, you will need to get a USB to RS232 adaptor.
I have never used the interface on the driver to do any tuning, because it is so much easier using the software.
Tuning with no load is not right and may cause the controller tuning to fail, or make the axis very spongy, so make sure you have the mass of the table there while tuning.
Also make sure you save it after, or you will delete the tuning, once you cycle the power.

Ye, ive been unlucky. Ive got 2 machines with native RS 232 ports as well as a USB one and PCI Express one. I cant get any of the 4 to work.

I need to do it again, but busy finishing Thor. If all goes to plan it might do some basic movement this weekend on all 3 axis.

I've got a cheap USB adapter, and have never had any problems. I did have to destroy the case to get it to directly fit onto the drives though.

Are you using the correct type of cable?
You'll need to check if it should be a straight through cable, or crossover cable (I would guess it should be a crossover for serial comms). Probably best to test the one you've already got, and then order the opposite.

I had tried a cable and had cut / moved the wires manually. I should just order one of each and test again.
