Which software control the cutting

Postby Jeff » Wed Jun 13, 2018 11:13 am

I have a question about which program is controlling the cutting on my XXL
I use Vcarve Pro to design and then choose the the Shapeoko post processor to save the Toolpaths.
So I have to open the file in Carbide motion and load the toolpaths to run the cut.
So is CM running the machine or vcarve.
My next question is this is there some other controller that can be used on the shapeoko that would allow me to change the speeds rate on the fly.
Other than the new version 1.1
Which I see a lot of post with people having trouble getting it to work right.

Grbl 1.1 affords on-the-fly feed rate overrides.

Carbide Motion 4 provides an interface for that. To update see: http://carbide3d.com/carbideupdater --- if you need to revert: http://community.carbide3d.com/t/grbl-1 ... -4/4403/21

List of other programs at: https://www.shapeoko.com/wiki/index.php ... _/_Control and https://www.shapeoko.com/wiki/index.php ... nterpreter

Hi Jeff,

In your scenario, Vcarve Pro, with the post processor, defines and generates the gcode that specifies the paths the spindle will move along. You load the gcode into Carbide Motion, and then CM takes care of sending the codes to the machine. Thus, CM is what is actually controlling the machine.

It is worth noting that the functionality of changing the speeds on-the-fly was introduced in grbl v1.1. Grbl is actually the software that exists on the circuit board inside your SO3 (on the Carbide Motion Controller); it is not part of the control software that is on your computer. If you want to use the on-the-fly speed change feature, you have to update the grbl version on your XXL machine itself. Once you have done that, then you also need to have control software that supports sending grbl v1.1 commands. CM 3.X does not, but CM 4.0 does.

Will provided a link to other software than can be used to control the SO3, in lieu of Carbide Motion, but I don't know which ones support sending to grbl v1.1.
