Sometimes we just have to share the best seat in the house.

The Gecko G540 comes to mind http://www.geckodrive.com/geckodrive-step-motor-drives/g540.html

At your controller end you should have a single point Earth connection - that is where all wiring shields should be connected.

I bought SolidCam but would aslo like to try any free package. Which one would you recomend?

There are so many to choose from you will just have to look around. It's a few years ago now but I used G-Simple when I started out http://gsimple.eu/

Connect the shield to Earth at the controller end only and see if that helps.

Further thoughts…

Those TB6600 drivers have a bad reputation, probably because there are a number of sub-standard clones being sold, but I have used 8 of them recently without issue. You have to open then up to check for solder blobs etc. and adequate heat sink goo and it is also good practice to fit an insulator between the back of the pcb and the heat sink but other than that I have found them to perform well.

Hi Dave,

Ashamed to admit it but I buy a lot of electronic stuff from China and I always allow for a 20% reject rate (it's cheap but still comes out on the plus side).

A very good friend of mine, in the Netherlands, reminded me this morning...

"If you want the best seat in the house then you have to move the dog"

Is this the same in other countries around the world ??
