Thanks! I agree with your recommendation. I saw your recent post (tweet), and am excited with the new 3DClippy using a servo motor. I have two questions about that. 1. Will the servo motor be connected to the 3DChameleon board or to the Raspberry Pi that I will buy separately? 2. Will the new 3DClippy work with 3D printers with cantilever structures like the P rusa MINI+? I am wondering how much more the weight of the print head will increase with installation. I look forward to more information, pictures and videos about the new 3DClippy. Additionally, I found a post in the forum about the 8-color version of the 3DChameleon. I am curious about this as well, so I hope you will publish pictures and videos in the future. Thank you for your tireless efforts. Hiro

Hi Bill, Sorry for the delay in contacting you. Appreciate your many advices about Mode 1. I tried changing the inner diameter of the tube from 2.0mm to 1.9mm (couldn't afford capricorn tube), and filament materials (PLA, PETG), and adjusting the tension of the extruder, the nozzle temperature to form the thinner filament tip. However, due to my inability to do so, the filament stopped flowing after the second layer while printing, or the filament got stuck in the hotend while changing. So I decided to use 3DChameleon in not mode 1 but mode 3 when integrating it into the PrusaMINI+. The filament path is longer, so it takes more time for that loading, but this mode does not require many adjustments, and with a few adjustments to Gcode, the printing and filament exchange is stable. When unloading the filament, even if I change the temperature, a clean tip is not formed, so the forming motion may need to be improved (or 3DClippy). This change allows me to enjoy multi-color printing on my 3DChameleon without frustration. Also, I use a Prusa stock extruder so this mode is adaptable for fast printing with input shaper (5.1.0-alpha1 firmware). I understood through experience your description of these modes. 1) Loader/Unloader Mode ... this is the easiest method of installation, but is a little slower. 2) Direct Drive Mode ... This is a harder installation, but allows for much faster color changes. (Source: https://www.3dchameleon.com/mk3-mode-2-gcode-generator) I will continue to make adjustments for better printing. Thank you for such an interesting product. Looking forward to future updates. 4-color object, printed in eSUN PETG with Prusa MINI+ & 3DChameleon Layout: 3D printer, 4 filaments and 3DChameleon Object and wipe tower 3DChameleon logo keychain

Dear Bill, Thank you for sharing the profile (3mf). I downloaded the python script from the YouTube description. I have tested single-color printing with your profile and Tool 1, but still it does not print well after the second layer. After checking the post below, I printed and replaced the A+ parts, but no improvement. https://www.3dchameleon.com/forum/support/tool-1-and-2-pull-with-less-force Is it this difficult to use 3DChameleon with Prusa MINI+ in Mode 1 (direct drive mode)? I would like to know if there are any other parts to check, solutions, or reference videos (adjusting tension, etc.).

Sorry, I have one more question. Does the Mk3 Gcode Generator support not only Loader/Unloader but also Direct Drive mode? https://www.3dchameleon.com/mk3-gcode-generator

Dear Bill Thank you for the advice. The spacer is between the unit and Prusa's stock extruder motor. I adjusted the alignment of the gears and printed the XYZ cube in one color. I really appreciate it. Single color printing with Prusa MINI+ & 3D Chameleon (XYZ 20mm Calibration Cube by iDig3Dprinting) However, I have discovered a new problem. I used PrusaSlicer preset for Prusa MINI+ (0.20mm QUALITY @MINI) and it cannnot print the second and later layers cleanly. Changing the speed from 100 to 70-80 in the LCD improves that problem (but does not solve it completely). Printing data is here: 3DChameleon B/C Replacement Parts with PTFE Grip by wjsteele. First layer (eSUN PETG, 240/85℃, Speed:90) Second and third layers (eSUN PETG, 240/85℃, Speed:90) So I would like to know your printing profile and what you care about (e.g. speed, retraction, temperature). Also, where do you publish your detailed print settings? Hiro

Dear Bill, I have printed your tension tuning sliders (Tension: +2.00, Spacing: default) and mounted it on the unit, but as usual when the filament reaches the nozzle it slips and does not load and print well. I would like to know what slider you use if you use it on the Prusa MINI+. And any other advice would be appreciated. I am having trouble using your kit, as I cannot print even with single-color, let alone multiple colors.

Thank you Bill! I did not print the sliders, and tried with the ones built into the kit. I will print and find the right slider for my filaments. For future reference, I would like to know which slider you set when you use the 3D Chameleon with PrusaMINI+. in addition, when you want to use various materials such as TPU or carbon filament, do you disassemble the unit and choose a slider each time?
