remcoder

I designed this to repurpose an old soap tray.

Hi everyone, I wanted to share this tool that I created: GCode sort (https://gcode-sort.web.app/)

https://i.redd.it/tmdo4t1b2rm81.gif

What is it?
This tool will optimize a toolpath's total distance and therefore it will reduce the total run time. It does this by re-ordering the cuts such that the 'travel' distance (ie 'not cutting') is minimized.

How to use it?
Drag 'n drop your gcode file. Press the 'sort' button. Check the preview if the design still looks good. If so, click on the download button for the optimized file.

Why did I create this?
I was routing a design for a friend, the chessboard in the example, and we noticed how i

Here it is. My first color mix print! How does this work? Well, it is a feature of the Geeetech A20M (and also of the A10M and A30M) which has a 2-into-1 or "Y" nozzle and 2 extruder motors feeding it.

Via the standard firmware, Geeetech's fork of Marlin, you can:

• switch between two spools of filament
• set a color mix ratio, say 30% of spool 1, 70% of spool 2
• define a changing color mix aka a gradient.

You can do this at any given time, even when you're in the middle of a print.

This vase was sliced normally, so the gcode has no instructions for dealing with multiple extruders, and the the gradient was configured before the start. From 100% purple & 0% pink to 0% purple & 10

I have the 750x750 version of the OpenBuilds OX cnc and I'm still putting the machine itself together while I realized that I really need a table for it so I decided to design and make my own.

The plan is to use mdf for the tabletop and the shelf at the bottom. The rest will be spruce.

I was wondering what you guys think about it, in term of sturdyness, vibration etc.

Here's a picture of the design and here's the Tinkercad version.

My son's 'roadblock with lights' toy broke. So decided to fix it and while at it I though to myself, why not spice it up a little bit by adding a micro to it?

For this I used an ATTiny85 had lying around as it's the smallest micro I have. The cool thing is that it it can still be programmed using the Arduino IDE, it just requires another Arduino to act as the programmer.

First I cut some traces that connected the LEDs together. Then I wired them separately to an ATTiny85 so they could be controlled individually.

Hoi, ik was te laat voor de standup :-( Vandaag ga ik weer eens verder met LEDs, pingpongballen en mijn nieuwe liefde: de NodeMCU (aka ESP8266). Ik ga patronen programmeren en projecteren op een ring van pingpongballen die aangeven wanneer er een FB-like of retweet van een q-blogartikel is. Daarvoor moet ik even uitzoeken hoe ik zoiets als setTimeout kan doen in Lua.
