3D Printer control via Gambas

Its easy to write some Gambas code to provide basic control of a 3D printer.

You just need a good G-code reference list.

These notes were born out of a few experiments I recently conducted with my Creality CR-10-V3

3D Printer: isolating the USB 5Volt feed

I'm really not happy that my printer's display "lights-up" when I turn on my connected computer.

This is not how USB is intended to work when connecting one 'machine' to another.

So I had to come up with a fix.

3D Printing via Cura on Linux

I'm getting a bit bored with transferring g-code files to my printer's SD card.

 

Its not one of life's most difficult tasks.

But I thought I'd try printing from my laptop, and see how I get on with it.

My Bleepin' 3D Printer

My printer knows how to bleep!

 

That is to say that the controller has some kind of audio transducer which can make sounds.

So this post is about putting it to use.

3D Printing: printer to Linux computer serial link

There may be times when you want to link your printer to a Linux laptop via the serial link.

 

Its very handy to be able to slice and print straight from a connected computer.

...so here is the procedure.

Raspberry Pi Serial Comms: Gambas + wiringPi

I've been playing around with serial comms on my Pi/Picaxe dev rig.

Using Gordon's wiringPi library makes it easy to open the gpio serial comms port on the Pi and write code with Gambas.

So this post involves writing a simple Picaxe program, and then using wiringPi and Gambas on the Pi to communicate with the Picaxe.

RaspberryPi, Serial Comms & PHP

I've been playing around with serial comms on 2 Raspberry Pi computers for the last couple of days.

And I now understand a little of the black-art required to get this working, including how to send serial data via a PHP web page.

So I thought I'd write up the details before I have time to forget it all again!
