Electronics for New Machine + Chinese Spindle + VFD

[mturneruk]

Hey George.

I decided to run a little bit more to see how often the problem occurred and see if I could spot a pattern. E.g. Did it always happen under load ?

Well i have just run nearly 1/2 a million lines of GCode cutting a complex 3d model with 6mm and 3mm ball noses (in four batches) and I have not had one reset.
I was getting really adventurous on the feed towards the end of the job. Ended up running at over 4000 mm / Minute.

I will keep an eye on it for now and record when and if I get resets.
I will definitely run a separate bare earth wire to the machine through the dust collection PVC pipe to ensure static is not an issue and earth this to the machine as well. Then I can disconnect the shielding of the VFD cable at the machine end as you suggested.

One thing you said has definitely helped me and that is to make a note of my machines co-ordinates at my job Zero point.
This allows me to check that my machine is absolutely in the right place for each session of machining i do, and return to my zero point if I should get a reset. Very good idea.

Will keep you posted.
Thanks again.
Martin
