Modbus / Re: Arduino (UNO) ModBus and Mach3

« on: May 16, 2012, 03:10:49 AM »

Hi,


So I got the 3 x Axis working, but when I try to fine tune the motors for some reason the X-Axis seems to not work fast, I tried differend hardware changing pins etc etc, eventually changed X for Y on all the electronics, but it seems to jitter. 

And I have gone through all the software configurations possible on that screen acceleration / speed phase for the pulse and direction, but still very jittery?

Is this a known bug with the software ?

Hi Ian,

Wow as a moderator you are a really helpfull guy, you bet I will stay with your site.  Have been to many sites and one can expect half the assistance and feedback.

So now yes this is just a small prototype, once I get the little motors to turn I can build a basic X - Y - Z machine which will eventually pave the way for a larger one that can do some milling. 

I only really want to mill PC boards as a conveniece, and my dad is in the metal industry and is super interested in getting some metal cut to size and it looks like Mach3 is the ideal candidate with all its settings.

So will keep posting feedback to this site.

Hi again,

Okay I hear what you are saying, I think I was side tracked here perhaps, I was following a thred from some guys blog and understood he did his milling machine this way. 

Way forward

So I have 3 x sparkfun easydriver boards and  3 x stepper motors, I will attempt to run the sparkfun stepper motor boards directly of the Parallel port instead of the Arduino board, there should be enough juice from the Parallel port.

I will update this thread with my progress and hopefully it will help someone else. 

Thank you Stirling, you have been a great help "eye openner" and I very much appreciate your help.


Kind Regards, Will be updating this thread in the next month while the project takes of.

Hi thank you for the fast response.

So is there a way to get a comprehensive tutorial or guide how to get Mach3 to talk to Arduino Mega/Uno to do milling ?


Thank you

Oh and one more pictue I left out Function Cfg's >> Setup Serial Modbus Control the Modbus Config screen

HI,

This will be my third week I'm trying to get my Arduino to run any one of my Stepper motors through Mach3  .

I took some screen shots see if you can find what I might of had configured wrong any suggestions will be very welcome.

I have read so many of the links on this site but not one of them helped.

1. Modbus Installed tested and working using Test ModBus Application





2. My Ports And Pins Setup Screen Config >> Ports & Pins





3. Motor Output Config I"m using
      Digital pin 2 For X.  and pin 3 for direction
      Digital pin 4 for Y.  and pin 5 for direction
      Digital pin 6 for Z.  and pin 7 for direction



please feel free to mail support@killarneynet.co.za me I so am enjoying this chalange and am so confused.

Thank you
