Key insights

• ⚙️ The SV07 printer has independently driven z-motors and an inductive probe for automatic bed leveling, while the SV06 and T300 printers use a slower and less accurate brute-force method for bed leveling.
• 🛠️ Introducing a Klipper macro and a replacement knob as an alternative gantry alignment method for SV06 and T300 printers.
• 📏 The T300 printer features a quick and accurate leveling method that heats the bed, probes the sides, and provides prompts for adjustments, resulting in a calibrated gantry that remains level for subsequent prints.
• 🔧 Guidelines for setting up and customizing the T300 3D printer, including using PLA for printing, Orca slicer with recommended settings, and PEI sheet with isopropyl alcohol for bed adhesion, along with the installation of a new knob.
• 🖥️ Steps for adjusting the 3D printer knob fit, adding a macro to the web interface, editing the printer.cfg file, and preheating the bed for z-tilt calibration.
• 🎬 The provided video offers step-by-step instructions for calibrating the 3D printer, adjusting settings for z-tilt macro and mesh calibration, and emphasizes the importance of making manual backups before editing Macro.cfg.

Q&A

• What does the video focus on in terms of calibrating the 3D printer and editing settings?

  The video provides step-by-step instructions for calibrating the 3D printer, adjusting settings for z-tilt macro and mesh calibration, and emphasizes the importance of making manual backups of Macro.cfg before making changes.

• What are the steps for adjusting the 3D printer knob fit and adding a macro to the web interface?

  The steps include adjusting the 3D printer knob fit by softening or scaling down, adding a macro to the web interface for z-tilt calibration, editing the printer.cfg file to include the macro, and preheating the bed to customize temperature for z-tilt calibration.

• How do you set up and customize the T300 3D printer with a new knob and macros?

  To set up and customize the T300 3D printer with a new knob and macros, you should print the parts with PLA, use Orca slicer with recommended settings, ensure bed adhesion with a PEI sheet and isopropyl alcohol, and install the new dial first after removing the original knob.

• What is the leveling method for the T300 printer?

  The T300 printer has a quick and accurate leveling method. It involves heating the bed, probing the sides, and providing prompts for adjustments. Once calibrated, the gantry remains level, and the bed mesh does not need to be redone for every print.

• How does the SV07 printer achieve a level bed?

  The SV07 printer has independently driven z-motors and an inductive probe for automatic bed leveling. In contrast, the SV06 and T300 printers use a slower and less accurate brute-force method for bed leveling. Additionally, a Klipper macro and a replacement knob are introduced as an alternative gantry alignment method.

• What was the speaker's original idea for the Comgrow T300?

  The speaker had an original idea for the Comgrow T300 but was unable to reveal it before. The solution relates to addressing the leveling problem in early batches of the T300. They will demonstrate the solution and discuss the background of the machines.

• 00:01 The speaker initially had an idea for the Comgrow T300, but was unable to reveal it until now. The solution relates to the leveling problem in early batches of the T300. They will demonstrate the solution and discuss the background of the machines.
• 02:09 The SV07 printer has independently driven z-motors and an inductive probe to achieve a perfectly level bed, while the SV06 and T300 printers rely on a brute-force solution, resulting in slower and less accurate leveling. A simple Klipper macro and a replacement knob are introduced as an alternative gantry alignment method.
