GCODE not compatible with grbl 1.1 HELP!

[oraherb]

please help me im a new to cnc so i got this problem with gcode when i try to send this gcode to universal gcode sender..it gives me an error "an error was detected while sending OS30: error:1" im using GRBL 1.1 and UGS i know that the gcode im using is from the inkscape and M300 S30 and M300 S50 is the issue because when i use and gcode and sample gcode that dont have those value it works so how can i create a gcode that is compatible with grbl 1.1 please help me

the gcode i was sending is like this

G21 (metric ftw) G90 (absolute mode) G92 X0.00 Y0.00 Z0.00 (you are here)

The M300 looks suspicious along with some other M-commands... Those commands are not supported by GRBL. How did you generate this gcode?

[oraherb]

@breiler i create gcode in inkscape and it is automaticaly created

[breiler]

Which plugin?

[oraherb]

@breiler sorry im new to this what im still learning what plugin?? the mi inkscape extension? dxf_input.inx dxf_input.py servo.inx servo.py

or the

MI GRBL Z-AXIS SERVO Controller

or

unicorn plugin

[oraherb]

please help guys

Dude it's impossible to help you with this little information... Did you follow a guide?

Let's start with the hardware and GRBL-firmware:

• GRBL does not support servos so I suspect that you are not using a standard build (https://github.com/gnea/grbl). Where did you download it?
• How are you connecting the servo to the Arduino for the pen?

The plugin for Inkscape is quite important and is really dependant on the right hardware. I couldn't find anything on "MI Inkscape plugin" or "MI GRBL Z-AXIS SERVO Controller".

It looks like the Gcode you posted first comes from the "Unicorn plugin" (https://github.com/martymcguire/inkscape-unicorn) which requires the right hardware. More specifically it was designed for "MakerBot CupCake CNC" which I believe uses Marlin firmware popular with 3D-printers.

Ex. the M300-command is used for playing a tone using a specific frequency which I guess can be used for signalling a servo. (http://marlinfw.org/docs/gcode/M300.html)

@breiler im using this grbl (https://github.com/gnea/grbl) and its not modified and using ardruino nano with stepstick drv8825 i connect the servo with DIGITAL PIN 11 and GND and 5V on arduino

[oraherb]

@breiler but my issue is not the pen and servo my gcode that i send from inkscape gives me an error so how can i create a gcode that can run in UNIVERSAL GCODE SENDER please help to make a gcode that compatible with (https://github.com/gnea/grbl) this grbl thats only my problem how to make compatible gcode sir please thanks

[breiler]

There are alot of options, when I started I used Easel from Iventables: http://easel.inventables.com/

It can export gcode, have look at the following link for instructions: https://inventables.zendesk.com/hc/en-us/articles/360012762533-Walkthrough-Tutorial-Offline-Easel-Usage

Other than that you can have a look at this page from Shapeoko and pick a tool that suits your needs: https://wiki.shapeoko.com/index.php/CAM
