Engineering Updates June 2023

Hello, Giga Friends! Happy summer from Texas! It’s been an amazing few months since we released Gigabot 4, Terabot 4 and GigabotX 2 at the start of the year. We’ve reconnected with many long-time Gigabot owners seeking upgrades, taking advantage of our free parts for older machines (don’t know about those? Get on our mailing list!) or purchasing new printers to add to their Gigabot family. We’ve also met many new owners doing fascinating projects with 3D printing as we continue to roll out our most advanced Gigabots, yet. 

The re:3D team has grown quite a bit, and on the engineering side, new teammates have taken on the task of putting fresh eyes on our parts and firmware to continue to iterate and improve our newest version, especially taking into account the feedback you have shared with us as beta testers and new owners. As such, we’re excited to share some updates with you on the progress of a few projects. As an open source company, we’re happy to report where we are in development of new tools and features for your 3D printers, stress testing and implementing them on Gigabot as they mature.

Touchscreen Case – Project Leads: Sami Hill and Alejandro Leal

With the release of the new versions of the 3D printers came the exciting addition of the full color, front mounted touchscreen, and it’s been a huge improvement for user interface over the previous VIKI controller. This is a work in progress update, and this case will be released as soon as it is fully tested. We’ve identified three main areas in which we’re iterating for an even better user experience:

  • Case Durability and Rigidity
  • Cable Connection to the Touchscreen
  • USB Drive Connection Point

Case Durability and Rigidity
We want this case to protect your touchscreen from bumps and falls as well as stay rigid when the touchscreen pivots on the mounting arm. As such we’ve thickened the case and bezel, putting more protective material around the sensitive electronic parts.

Cable Connection to the Touchscreen
Inside the thickened case, there is new cable routing to make sure cable bends don’t exceed their minimum bend radius, and we have added a cable sleeve at the entry point to minimize abrasion on the cables as the case moves.

USB Drive Connection Point
One of your common pieces of feedback is that the USB drive slot on the touchscreen is sometimes misaligned with the case. We’ve added internal bracing to that slot so the cable stays put and cleanly receives USB drives to load files onto the 3D printer.

Simplify3D v5 – Project Lead: Jordan Smith

The release of Simplify3D v5, our preferred slicing software, came with some great new features we’ve been testing on Gigabot. We’ve been most especially excited by the new infill and support patterns allowing quicker, cleaner support removal and morphing infill for stronger internal structures and better top layer finishes. Simplify3D v5 also added support for Klipper commands, which we’re excited to explore. Alongside the new software release we now have fully tested Simplify3D v5 FFF profiles available for your Gigabot 4 3D printers.

Klipper Software – Project Lead: Mitchell Mashburn

We have been diligently progressing on a new software update, v0.4.0 for Klipper stack, expected to be released soon. This update, based on your feedback, aims to offer a more optimized and up-to-date software experience for Gigabot owners. As part of this update, we have upgraded various components, including the Klipper firmware, Moonraker API, and Mainsail front-end interface. Detailed changelogs for each component are available via the links below.
While we conduct further testing before the release, we invite Gigabot owners running Klipper to participate in our alpha/beta testing program and gain early access to software to help us identify issues (apply here:
Version 0.4.0 Upgrades Include:
Klipper (firmware): 0.10.0 -> 0.11.0 — See full changelog here:
  • Improved error handling for the max31856 temperature sensor
  • New modules added, notably exclude_object which allows skipping an object on a multi-part print
  • Various bug fixes
Moonraker (API): 0.7.1 -> 0.8.0 — See full changelog here:
  • Data structure change
  • Improved update manager
  • Improved metadata parsing for Simplify3D V5.
  • Various bug fixes
Mainsail (front-end interface): 2.3.0-Beta -> 2.5.1 — See full changelog here:
  • Option to change date & time format in settings
  • Add jobs to queue in batches
  • Send PAUSE at a specific layer change
  • Various bug fixes
Additional Changes & Features:
  • Webcam/timelapse integration
  • Simplify3D v5 thumbnails
  • Support for SD card looping to run continuous prints/gcode – M808 command
  • Removed screensaver on touchscreen
  • New and improved scripts to automate software upgrades and maintenance.
  • System dependencies upgrade
  • Image compression upgrade. (now not limited to balena etcher 1.5.15)
  • Update and version control improvements
  • Path changes.
  • Various bug fixes
  • Minor UI changes – macro placement, panels, etc
  • Updated README
We are committed to continuously improving Klipper and have several exciting features on our watch list, including automatic bed leveling, remote monitoring, control, and support, among others.
Have any questions or comments about these updates? We encourage you to add comments on our forum, or shoot us an email at Thanks, and happy printing!

re:3D® kicks off their 2023 Gigaprize Campaign, giving away an industrial 3D Printer to someone committed to uplifting their community.


HOUSTON, June 1, 2023 — re:3D, Inc. is pleased to announce the kickoff of their 2023 Gigaprize campaign. For every 100 printers sold, re:3D donates a Gigabot 4* large-format, industrial 3D printer to an individual or organization committed to doing good in their community and/or society. Past Gigaprize winners include, among others, Magic Wheelchair out of Portland, OR, who provides 3D printed Halloween costumes for kids in wheelchairs, and Tunapanda Institute, incorporating region-specific 3D printing educational curriculum and opportunities to serve community needs in Kenya. The application for Gigaprize is live as of June 1st, 2023 via the re:3D website ( Submissions will be accepted until June 30th, 2023 at 11:59PM CDT. Applicants will need to produce and upload a short 3-minute video explaining how a Gigabot 4* would help in furthering their mission and fill out a short questionnaire. Judging will take place during the first two weeks of July, and the winner will be announced mid-July. To remain impartial, re:3D will bring in external judges with a wide range of experience and expertise. All contestant videos will be uploaded to the official re:3D Youtube channel and a small percentage of the final score will be based on the number of “likes” each video receives. 

*Gigabot 4 or equivalent store credit towards another 3D printer.


re:3D® Inc. consists of a group of explorers committed to decimating the cost & scale barriers to industrial 3D printing. Having pioneered the world’s first and most affordable, human-scale industrial 3D printer, re:3D likewise is creating large scale, affordable 3D printers printing from pellets, regrind, and flake plastic waste. Beyond creating 3D printers for customers in over 50 countries, re:3D offers 3D printing contract services, consulting, design and education services. For more information on re:3D, visit
