New to cnc and software controls, need some help
« on: September 18, 2012, 07:40:05 PM »
 Hello to everyone and thanks for all the work you've done

    Im totally new to cnc and the hardware and software but I have managed to get enough together to build my first rough draft machine and get modbus working with a arduino and mach 3 but have yet to connect my controllers up to the arduino due to having no clue what pins to use with Shillings modbus sketch I found posted on here.


   can anyone help out with which pins I use for these connections?

I have exactly the same issue. I have a DIY machine and therefore have no "manufacturers specs" of which pins to use. The other issue I also seem to share with you is that I have asked the question (on a support forum) but yeah well, you get lots of views but no support?

Getting discouraged  >:( >:(
When I die, will someone please dress up as the Grim Reaper and attend my funeral. No need to do or say anything, just attend and stand a short distance away? PLEASE???

Found this on the CNC zone forum

 two arduino modbus threads at the Machsupport forum

Maybe other place to look?

Thanx been there too, that post is ref back to where we are now, Machsupport and the two threads they refer to there also don't have much....

But I have studied the PDF that the author of the Modbus pde file for the arduino and Mach typed, and it seems that (perhaps I am getting close to understanding it better) one has to have the register tables and reference sheets printed out and have them next to the laptop/PC when within a brain as it seems that specific kind of in-outputs and functions have specific addresses in Modbus and is seemingly also restricted to specific registers. So perhaps having these next to the PC it might be easier to write a brain that will be functional.

All I need to do now is to write a couple of small test brains and see if I can get some reaction from any of the features on my machine.
