MakerBot Replicator: Print Quality #2

Having upgraded the Replicator's firmware, I was able to run a couple of test prints using acceleration.

This allowed me to print a TreeFrog in under 30 minutes.

Following on from my previous posts on the Replicator and Print Quality, I wanted to try a print with acceleration. But my first problem was locating the acceleration mode on the Replicator... didn't have one.

MakerBot Replicator: Print Quality

What level of print quality can you expect from your new MakerBot Replicator?


Here are a few illustrations which I hope might help show the sort of results you can expect from this model of 3D printer.

...Or maybe you get better results, in which case, I have a problem!

Having levelled the Replicator platform and left all other settings at their default values (e.g. nozzle & platform temperatures) I selected the "whistle" from  the ReplicatorG software example list as a test piece.

The 3D Printer: Toy or Techno-Wonder?

I was lucky enough this week to get my sticky little hands on a 3D printer: the "MakerBot Replicator".  So what's all the fuss about?

First impressions are that this printer has been built using old parts from a flat-bed scanner, and housed in a primitive, makeshift, wooden chassis.

But on closer examination, the chassis is in fact a very sturdy structure, closed at the base and the back, but open on the other four sides.

Recovering Lost Files With Linux

Unfortunately data loss and corruption are common ailments in memory devices such as hard disk drives, solid state memory cards and USB sticks.

It doesn't matter if your faulty device is a memory card from your camera, or a hard drive from an Apple Mac or a Windows PC, all may not be lost if you can connect the device to a computer and use a couple of magical Linux tools.

The other day I was handed an SD card, which should have contained the record of a great holiday in Egypt. There were a few jpeg files listed in file manager, but they would not open, and many seemed to have a file size of 0 bytes.

The outlook was gloomy (as was my well-tanned friend) but in just a few minutes I was able to restore over 200 happy holiday snaps.

Gambas: Improving the PhotoViewer

By making the transition from Gambas 2 to Gambas 3, I've been able to increase the functionality of my Photo Viewer application, and make a few improvements along the way.


A new Gambas component has allowed me to add image histograms, rotation and normalisation to my project.

This new component is called gb.image.effect, and although it includes methods to despeckle, emboss, invert, oil-paint and solarize an image, I've only made use of a couple of the available methods.

When The Dishwasher Runs Dry

When your dishwasher stops washing dishes, you better fix it fast, or spend hours up to your arm-pits in soapy water, doing the washing up!


Our dishwasher started running "dry", a problem I had seen 3 years ago, so I knew just what to do.

Like most dishwashers, our Bosch LogiXX gets a lot of crap thrown at it. But the two most difficult substances for it to swallow are fruit pips and fat. The pips are usually from oranges and lemons. They whiz around the internal pipe-work until they get stuck in those rotating arms that are supposed to spray water over your crockery.
