Hi folks
Today I m try run G code driver on my first machine , on this moment I use GRBL for that and Cri.s is help me allot for run that GRBL , but that not work on last version OpenPnP and Cri.s say that can use G-code driver , but like I m say before I m not programmer and not have idea what I need do on real.

I m look this : https://github.com/openpnp/openpnp/wiki/GcodeDriver but again do not know what on real need do , how need machine.xml look for 4 axis machine with one head , same is with 2 head machine .

Have some one who use that G-code driver that can add machine.xml files for look how that need look ?

Hi Moja,

Here is a basic driver configuration that should get you going. You will need to change the serial port and baud rate settings. This is based on the old GrblDriver, so it should work similarly to that one. Just edit your machine.xml and paste this in in place of your current driver section.

<home-location units="Millimeters" x="0.0" y="0.0" z="0.0" rotation="0.0"/>

<command-confirm-regex>^ok.*</command-confirm-regex>

<connect-command>G21

G90</connect-command>

<home-command>G28</home-command>

<move-to-command>G1 {X:X%.4f} {Y:Y%.4f} {Z:Z%.4f} {Rotation:C%.4f} F{FeedRate:%.0f}

G4 P0</move-to-command>

<pick-command>M4</pick-command>

<place-command>M5</place-command>

<sub-drivers class="java.util.ArrayList">

</sub-drivers>

</driver>

The newlines in the connect-command and move-to-command are important, so don't remove them.

Once you have this working you can refer to the documentation to add additional commands if you need them.

Moja,

As long as you install into two different directories it should be okay. The only problem is that if you use the same user to run it then they will share the same $HOME/.openpnp configuration directory, so it will get confused. I'd recommend creating a second user on your machine and install and run the new version for that user. That will keep them separate and it should work fine.

Hi Moja,

There is a lot of special functionality in that driver that it will not be possible to do the same way, or at all, in the GcodeDriver. Do you need all of that functionality?

I suggest that you make a list of Gcodes and operations that you want the machine to perform and list them here, then I can tell you if the GcodeDriver will work for you. The first step is to identify all the things that machine must do.
