Hi guys, I have a hanging v-plotter with Uno R3 and Sensor shield 5.0, plugged to pc, any ideas how to implement this G-code to .ino file ?

I'm a beginner about Arduino :smiley: all help are very welcome ~

What exactly do you want to do with the G-code ?

Send it via the Serial interface perhaps, or something else ?

That G code, or G code in general?

Better to leave it in PROGMEM.

I just want to print the result shape to paper via attached hanging v-plotter :grin:

7

That G code for now, but this summer I plan to learn G code in general

8

Oh is it okay if I just paste this to an empty .ino file? Does it work that way?

9

Or, if you plan to change it a lot in future, place it in a file and read it from an SD card.

10

No. By itself, it will just sit in memory and do nothing. You need to upload code that uses it.

11

For now I don't have a SD card module so... but in future maybe I can get an SD module to try in other projects

12

so, pasting it to an empty .ino file, then send to the device via the arduino app?

13

I just tried it and, plotter is just waiting lol

14

What is "it" ?

15

The solution gcjr wrote through, and I opened a new sketch, pasted it in, and tried :smiley:

16

How is your plotter connected to the Arduino ?

17

R3 to Shield5 to 2 motors and, GVS-A0 goes for the penholding part, G11-V11,S10-9-8-7-6-5-4-3-2,G1-V1 to the 2 motors

18

No wonder the sketch doesn't work as it is trying to use the Serial interface. You need some software to take the G-code and turn it into commands for the motors so that they move as required

Have you got such software ?

Your original post implied that you already had a .ino file that controlled the plotter. Is that right ?

19

Have you made the plotter do anything at this point?

20

I don't have a software that turns Gcode to motor commands, but I got this Gcode from Makelangelo.

Yeah I have an ino file for testing the plotter, it works but I want to try the output of this gcode instead of just an infinite loop to display
