Let me now if you are considering doing something similar or different or if the Bowden setup is good for you. There is a V2 in design, but no details on that from the designer. There is an official triangle labs version, but only for the Voron variant. Make sure you choose the CR(eality) variant. Although I did a google result for one that is 2/3 of the price. I purchased through the Thingiverse page link because it supports the original designer and I doubt I could A) print the gears correctly or B) find the individual parts cheaper. At the end, Michael states that he has purchased 3 more. Interestingly, TeachingTech released a video 6 days ago about this so you can see someone install it in more detail. I ran some basic trials to wear the gears in and I've used silicone grease for the plastic gears and will add PTFE grease (sparingly) for the hobb gears. Bug Description Im using Orbiter extruder 1.5 and they recommend using ejerk at 5mm/s, but I cant compile Marlin usin. So it is either that or a bit of tolerance in the system. Did you test the latest bugfix-2.0.x code Yes, and the problem still exists. An effective diamter of 11.1mm gives the 690 steps I need. Any 'biting' of the hobb gear reduces the effective diameter further. The Hobb gear is 12mm diamter, but recessed to ~11.3mm. I was concerned as this is different to the main Thingiverse post, so I calculated the required steps and get very close. ![]() I use steps in the range of 690 steps/mm. The Orbiter v1.5.Key features:- Dual bondtech style 12mm drive gear - really high grip- Planetary gearbox with 7.5:1 gear ratio- Filament acceleration up to. I'd be interested to see what others are getting. So this has improved my flowrate 30% from my bowden setup. ![]() I have used 0.49V Vref in a cool room for 8+ hours printing at 13mm 3/s max (0.6 nozzle) and it is still good to touch for >10s. I set the Vref to 0.49V and it seemed a good balance. The wire order lined up perfectly with my existing motor, but I had to use dupont bread board connectors to join the different connectors (with electricians tape :/) Hopefully I can save you some time with this post. Overall, this took a good 10+ hours of time to research, test and install. My results for purchased AliExpress set on Ender 5 Plus with Creality silent board.
