Hi, guys,

I'd like to make the controller output digital or analog signal at each location to control a part of my device.
I could change the head speed by putting F code at the end of each coordinate.

X10.0 Y10.0 F20
X11.0 Y10.0 F20.5

However, I need to output at least one analog signal differently at each location.
Can I do as following to use the spindle signal?

M3 S10
X10.0 Y10.0 F20
M3 S15
X11.0 Y10.0 F20.5

In this case, the problem is that I should divide the path too finely and the voltage changes step-wise rather than gradually.

Isn't there any way to change the analog output voltage gradually by interpolating two values assigned at two different positions?
Thank you for your advice in advance.

General Mach Discussion / Ethernet controller?

This may be a stupid question, but this is because I'm a newbie in this CNC world.
I'm planning to order a CNC router from a relatively small company.
They recommended to buy an upgraded CNC controller (They call it an ethernet controller.).
But what is the difference between a normal controller and an ethernet controller?

Thank you so much, Russ and Hood.
As I've never used this kind of machine before, very tricky for me. :(

Thanks a lot, Russ! Have you used it before?
I knew its specification is fantastic, but I'd like to hear some experience.
Have you used it with Brains and Macros of MACH3?

Hi, isn't there anyone who can help me? :(

General Mach Discussion / Controller or breakout board selection
« on: May 08, 2013, 07:19:33 AM »
Hi all,

I'm thinking of purchasing a CNC hardware kit including all gantry frames, stepper motors and motor drives.
If I want to use the full capability of MACH3 such as macros and brains, which breakout board or controller can you recommend?
As I want to build something like a CNC machine with some extended capabilities, I need to have a clever Ethernet controller which can deal with several signal I/Os.
I really appreciate it if you give me some advice.
It would be great if you let me know its price range roughly.
