Hi Chieffy,

It could be switch bounce. Try increasing the Debounce Interval in Config / General Config and see if that helps.

Hi Jens,

The grounding / earthing issue is quite complicated but everything metal that you can touch (which comprises equipment connected to the incoming AC mains supply) must be connected to earth. Sometimes the incoming mains supply comes with a good earth, sometimes an earth stake is fitted close to the mains inlet.
Earth and Ground should be treated as two separate circuits when connecting up your CNC.
You must try to avoid Earth loops which could explain this

I found, that if I put it into the same power outlet as the controller, the steppers gets a lot more noisy.

The same applies to Ground loops which is why GND connections are only made at one end of shielded cables.
It may save you some time if you have a local friend who is an electronics expert who can look at your system and help you eliminate any GND or Earth loops that you may have.

My steppers make a high pitched sound when stationary if that's any help.

Tweakie, Thanks for the information. I'm ordering Gearotic Motion right now. I guess that should solve my remaining misunderstanding about this project plus allow me to do a whole lot more later.

Thanks,
Jim Gray

Hi Jim,

You won't be disappointed, Gearotic Motion is brilliant and it just keeps getting better (Thank you Art).

Ashleigh,

You may find some useful information regarding your Hermes in this topic over on the Zone. http://www.cnczone.com/forums/engraving_machines/

Hi Yoram,

I expect you have already seen this post http://www.phlatforum.com/viewtopic.php?f=264&t=2984 but that type of backlash would perhaps be difficult to spot and may not occur at every move. Curious because I have never seen it before.

Hi Jim,

Before I started using Gearotic Motion I used Gear Generator for the profile then the free version of CamBam to create the offset toolpath (tool radius offset). This then ran just fine with Mach without using the three G's.

Here's another non-Mach3 USB option.

Thanks for the info Gerry - more stuff for me to read up on

Hi Yoram,

Thanks for drawing attention to the Planet-CNC USB controller.
This board is available to buy complete or for those who can make their own PCB's, full constructional details (hardware, firmware and software) are available for the 4 axis version.
