Helping PLA Stick to Blue Painters Tape with Glue

by

If you run into issues with a big flat print warping in the corners and you can’t seem to get it to stay stuck to your blue painters tape we have a simple trick that might help. As always if possible redesign your piece to have small portions that break up long flat portions on the build plate and include recesses or other relief areas to make it smaller chunks of warping rather than one big area. To make your prints stick to the blue painters tape you can simply apply a thin coat of UHU glue where your print will be and slightly further out to ensure you get the edges well. If you just need a tiny bit of help to make the print stick, tracing the outline of the print or even just a good coat in the corners can be sufficient. This glue stick is easy … Read more

Tightening Replicator 2/2X Belts

by

If your prints are turning out significantly smaller in size in one direction, it is possible that it is being caused by backlash. This is when the extruder isn’t being moved as far as it should to make the proper size. The reason the extruder won’t move far enough when you have backlash is that due to a loose belt, the teeth of the gear allow slight play on the belt causing the extruder to drag as far back as possible on its teeth because that is where it will actually catch. Any change in direction  immediately moves it to drag the opposite side, this means the very edges of your print won’t ever be reached properly. Loose belts can be more severe as well if they allow slippage to occur and miss-align your gantry, but the solution to a loose belt is generally the same regardless of severity. There … Read more

Replicator 2/2X Gantry Alignment

by

During shipping, rough handling or over time it is possible for a gantry to come out of alignment on the Replicator 2 and 2X. This will be noticeable by your printer grinding because it won’t hit an endstop or printing objects at an unexpected angle compared to the front of the platform. This can be obvious on the initial bead of filament the printer primes its nozzle with at the front of the platform. If your gantry is out of alignment, the first thing to do is check to make sure you don’t have any loose belts that caused this as fixing this and leaving a loose belt with allow it to get out of alignment again. Once you have all your belts properly tightened you can then begin the process of aligning the gantry. To check the current alignment slide the gantry to the front of the printer and look … Read more

Sailfish for Replicator 2/2X

by

On most of our MakerBot Replicator 2 and 2X 3D printers, we make use of different firmware than comes stock on the printers. The firmware we use is called Sailfish. It is at a glance very similar to MakerBot’s version of the printer firmware but it has several significant differences that we find improve the capabilities of the printers. Added Features The first major feature we make use of is the option to Ditto print on a dual extruder machine. This allows you to print 2 of the same single color object at the same time, which is a great way to double the production of printed items that are smaller than the width between the nozzles. A second that can be a big help is the ability to override temperatures generated on your Gcode as well as fine-tune them mid-print.Sailfish also allows you to fine-tune your print speed mid-print. … Read more

Replicator 2/2X LCD Interface Button Replacement

by

We previously designed a replacement button for a Replicator 2/2X LCD Interface Panel. You can check out the Thingiverse post here: http://www.thingiverse.com/thing:784845 The issue was that it was designed to make use the heads of copper coated nails, this meant that in the long run there was a risk of damaging the board and wearing out the contacts on the board itself. These hard contacts also meant it was sometimes difficult to press the buttons as they had to line up very precisely. We found a product to allowed us to design another version of the replacement. It is a very simple to apply graphite liquid that will adhere to a rubber material. This made it a good fit for NinjaFlex. We printed a new version of the original button that made use of a circular bump rather than a recess to put the nail in. We followed the directions on … Read more
