SpiderBot V2.0 What’s new?

We are proud to reveal the V2.0, a major update of the SpiderBot 3D Printer. The 2.0 is not just another version number increment but also signifies the release of the dual extruder option (we skipped 1.9 just so it sounds better and matches the dual extruder release, haha!). Furthermore it includes many structural improvements and takes into account most of remarks and feedback from our customers around the world.

Ordering and availibility

The SpiderBot V2.0 will be available from the first of January 2015. As a consequence, from this moment onward, we would like to inform you that the V1.8 SpiderBot can no longer be ordered, we are accepting pre orders for the SpiderBot V2.0.

What’s new?

Dual Extruder

It has arrived! With the release of V2.0 we will now be offering the printer with the choice between a single and a dual extruder.

For an interactive 3D view, a video of the Dual Extruder in action, see our beta release blog post here.

We would like to thank all the beta testers for taking their time to provide valuable feedback and constructive criticism during the closed beta trials.

Autonomous Printing

By using the Raspberry Pi loaded with OctoPrint and optional camera, the SpiderBot can now be made fully autonomous with network access and can be controlled by any device with network access through a browser. This includes your desktop’s browser of choice but also on tablets and even smartphones. Get an accurate status of your print or simply check out the printing progress through the SpiderBot internal camera. Note, that even with this option installed, it is still fully functional with Repetier Host running on a seperate computer, the printer is reached over the network instead of the USB port.

OctoPrint is a great open source initiative within the 3D Printer scene, developed by Gina Häußge and sponsored by bq. It has a ton of great autonomous printer and web based GUI features. Check out the website here: octoprint.org.

Redesigned Parts

Single Head

In line with the dual design, the single head design has been updated. It has been simplified and as such has become easier to assemble or inspect for maintenance purposes.

Furthermore the stainles steel thermal break has been optimised. With reduced diameter and a polished inner hole. Due to the reduction in diameter, here is less material to transfer heat upward.

Extruder

A Hi-torque Nema 23 Motor has replaced the Nema 16 + gears. A simplified design of the original dual drive extruder, the filament is pulled by two gorges which avoid deformation and marks on the filament. This reduces the frictions in the PTFE tube, and guaranteed a very regular extrusion. Furthermore, opening of the service door does not change the preload of Polyurethane spring.

  • Possibility to take off the filament without changing the adjustment/setup of extruder.
  • Easier to adjust.
  • More robust (no gear in stepper motor, no complex mechanic).
  • Reduce the play inside the extruder, and the Prime/Suck values in KISSlicer.

Structural Improvements

Rails

New rails, made from stainless steel instead of aluminium offer better rigidity and due to the material properties of stainless steel, less thermal dilation. Furthermore the assembly has been made easier.

Holes and threading

All the holes in the aluminium parts that make up the SpiderBot frame are no longer threaded, instead Böllhoff RIVPRESS Plus inserts are used. These are stronger than alumnium thread and with these instead of threads, in case of damage won’t require the entire aluminium part to be replaced.

Main plate

A « maintenance door » allows easier access to the Megatronics board and wiring. This makes assembly easier and also allows a quick check of the wiring while the enclosure is still around the printer.

Electronical Improvements

New Cables and wires with Molex connectors

You have only to connect the wires on the Board, all other cables are prewired with Molex connectors and you can’t made error. You save an important  time on the cabling.

30A/12V DC Power supply with Fan Controller

A drop in replacement of the current 30A/12V DC Power supply with the additional feature of a On/Off Fan control circuit, meaning the fan will automatically start or stop depending on the temperature in the power supply. This nice feature reduces overal printer sound levels.

Easier Microswitch fine tuning

A steel blade can now be adjusted by a screw on the Microswitch contact. Simply adjust the home top position of the carriages with an Allen/Hex Key,
