3D Printer Retraction Calibration Vol II – Calibration Generator Program Release

Calibration Generator Program

Good day. Karl here. It has been a while since I have submitted any articles. I got burned out and my normal day job picked up considerably. I have been keeping busy but not with anything I would share by itself. I will start out with an update on what I have been up to. You can skip to the 3D printer retraction calibration section with the release of the Calibration Generator tool if you are not interested. What have I been up to? First, I have been doing a lot of gaming. Been playing Fortnite, Red Dead Redemption 2, and some other random games. I am trying hard to keep up with my son. Unraid OS. So many things to explore and learn. Docker, VM’s, and storage. There is so much goodness in this OS. I was able to consolidate several services into one box. I had a standalone NAS drive that I went way too long trusting my …

SC-10 SHARK is a Faster 3D Printer with Optional Laser Engraving, Bicolor, and Auto-leveling (Crowdfunding)

SC-10 Shark Faster 3D Printer

Printing a 3D model usually takes hours, if not days, so anything that can speed up the printing time while keeping the same quality should be welcomed. LOTMAXX SC-10 SHARK 3D printer promises to reduce the standard print time by up to 30%. How did they exactly make a faster 3D printer? Thanks to “Aeolus Heat Dissipation system” (AHDS) with four fans to cool the nozzle and “S Move System” (SMS) helping the motors travel at a high speed. The printer also happens to be a multifunction printer with support for laser engraving and bicolor printing. SC-10 SHARK launched on Kickstarter several weeks ago and raised over $200,000 US from around 620 backers with 12 days to go. SC-10 SHARK 3D printer key features & specifications: Molding technology – FDM Print Speed – Up to 200mm/s; normal speed: 45-90mm/s Printing Accuracy – +/-0.1mm Layer thickness – 0.1 to 0.4 mm Nozzle diameter – Standard: 0.4mm; 0.2 and 0.3mm nozzles are …

How to Recover from a Bad Firmware Upgrade on Anet ET4 3D Printer

How to flash Anet ET4 Firmware

Hey, Karl here with a really quick how-to. This how-to is to help everyone who has bricked their Anet ET4 printer after upgrading firmware on the printer. Anet reached out for a review of the ER4 and I recently gave one printer to a buddy of mine and he showed a lot of enthusiasm. I thought it would be interesting to do a review from someone less experienced. I asked him if he would like to do it and he accepted. I wanted to help him with unboxing and initial setup so we fired up a YouTube Livestream. The build went smooth but because the UI is lacking finish I went searching for updates. It is not uncommon to flash firmware, and after a little googling I found updated firmware and was hoping to fix the UI. We followed the directions but the machine got hung at the logo after rebooting. Damn. After a little more searching found directions from …

Marlin 2.0 Open Source 3D Printer Firmware Finally Released

Marlin 2.0 Firmware Release

Back in June, we wrote about Marlin 2.0 firmware supporting ESP32 3D printer board, but at the time the firmware was still in RC1 (Release Candidate) phase. I was informed Marlin 2.0 firmware had been in beta for several years now, but the good news is that Marlin 2.0.0 open-source 3D printer firmware has now been officially released. Some of Marlin 2.0.0 new features include: 32-bit support with several boards including Arduino DUE (SAM3X8E), Adafruit Grand Central (SAM5D), Smoothie / SBASE / EZBoard based on NXP LPC176x, SKR Mini powered by STM32, as well as ESP32 boards Some improvements were made to some AVR boards including Melzi (ATmega 1280), RAMPS (ATmega 2560), and RAMBo / miniRAMBo / Einsy RAMBo boards PlatformIO build environments for supported boards VSCode “Auto Build Marlin” extension for one-click build Power-Loss Recovery for SD print jobs Magnetic Parking Extruder support Magnetic Switching Toolhead and Toolchanger support Gradient Mixing and Gradient Virtual Tools Automatic power supply control …

Quick Update for the AnyCubic Photon S Photon Workshop V2.1.17.RC1

Just last week I did the first part of the review of the Anycubic Photon S. One of the pain points of printing was the long workflow. Chitubox Prusa slicer Photon File Validator Photon Workshop First thing I have to decide is if the model needs to be hollowed to conserve resin. I load up the model in Chitubox and use the built-in tool to hollow the model. After the models hollowed and a drain hole is placed I export it to an STL and open with Prusa Slicer. In Prusa Slicer, I orient the model and use its auto-support feature and auto-orient feature. It is a roll of the dice if the orientation makes sense. I want all the supports to be on the back/bottom of the print. Little marks are left when removing the supports. I have found that Prusa Slicer has the best auto support feature. Then I export to STL again with the supports and open …

How to install Duet 2 Maestro Board on HE3D K280 3D Printer

Duet 2 Maestro Wires Description

Quite a while ago I reviewed the HE3D K280 delta 3D printer.  Up until now, I did no mods other than the ones that I completed during the initial build. I have been very happy with it with the exception of the noise caused by inexpensive drivers and the salmon skin due to the drivers as well. The K280 prints big and pretty accurate at modest speeds. Today I am outlining how I upgraded to a Duet 2 Maestro mainboard. With this upgrade, I am jumping from an 8-bit board with generic drivers to a 32-bit board with TMC2224 drivers. The upgrade was quite painless and straightforward but not without a few hiccups. The Maestro is Duet’s entry-level board for about $130. I attempted the Bigtreetech SKR 1.3 with TMC2130’s but the firmware wasn’t quite there yet. I opened an issue on Marlin’s GitHub page which explains the issue in detail here. I only had one major issue with the …

Sovol SV01 Upgrade with BigTreeTech SKR mini E3 Control Board

Sovol SV01 Upgrade: Bigtreetech SKR mini E3

Karl here with a quick upgrade guide. The one complaint I had in the review of the SV01 3D printer was it was loud. Today we are going to look at resolving part of the problem by replacing the Creality board with the BigTreeTech SKR mini E3 V1.2 control board sold on Amazon for around $37. Fan noise at a later date. This board is ideal because the SD card, USB, and screws line up for nearly a perfect replacement. I did not bother hooking up the filament runout sensor. I have never found them particularly useful and always ensure I start with enough filament and bypassed it for the review. The board comes with TMC2209 drivers which significantly reduce the stepper motor noise as well as stop any salmon skin. SKR Mini E3 Warning This board is a replacement for the board found on the Ender 3. Below is from the manual. I purchased a clamp meter to test …
