I recently setup my CNC 3040T and after some help from a user here got everything working...or so it seemed.

I found someone on upwork.com to make a design I created into Gcode. As soon as I loaded the Gcode into Mach3 and started the cycle my stepping motors make a loud sound. It seems they are trying to go past the bounds that the machine is capable of working on. Is this an easy fix? The design looks great from a Gcode standpoint; however, not sure if coordinates should be adjusted.

*This is my first time using the machine*

Any help would be greatly appreciated!

If you are using the stock screens, then the toolpath tab should tell you the outside work area limits.

I think Mach will warn you if the work area is outside the table size, if you have soft limits set up for your table. You can also see the table outline if you select that display and then regenerate tool path.

Also check if the units are in metric...

Maybe post the first several lines of your g-code?

Thanks for the insight. It looks like only part of my design falls into a rectangular solid that represents my work space. Weird because I specifically asked the designer to make it an A4 sized area.

Units in Mach3 are in metric.

Here is some of the Gcode I have:

The code displayed stays well within the A4 boudaries so long as you have the orientation of the axis correct.

How do I determine if my axis is correct? I'm assuming it's not.

[Louis_Cannell]

Simply jog the X axis and make sure you are moving the axis you want to, if it is as you expect then the workpiece is loaded in wrong direction i.e. landscape portrait on a print.
Otherwise your setting in the software are incorrect, although if you were configured correctly a4 would be ok both directions.

I see, when I jogged the left arrow key it would move the head right instead of left causing it to hit the outermost bounds of the workspace causing the noise. Not sure if this is the issue because i could easily flip the machine and be fine.

The workpiece loaded in the wrong direction as in the Gcode?

I appreciate all the info your shooting my way.

[Louis_Cannell]

you need to swap 2 of the wires from 1 phase on the stepper motor that should reverse it
or

Under Config - Motor Home/Soft Limits, Check the Reversed column for the Axis you need to revers.

"Under Config - Motor Home/Soft Limits, Check the Reversed column for the Axis you need to revers." This worked perfectly, thank you!!

It seems we're working in landscape instead of portrait for this design, how would I go about changing this?

Did you just want to drill some holes,then that is not how you do a program to drill holes, what really were you trying to program

I am trying to make micro perforations on paper. All I need done is a program to drill these holes, this program won't do that?

Whats the grid pattern and your start point, is you machine set up in inch or metric

[PhilipY]

Metric, the grid pattern is a simple rectangle for testing purposes. The start point of the Gcode or the actual machines coordinates?
