We're hopping into the conversation a little late, but hopefully, we can shed some light on the PLA printing issue raised by @wesc. Despite the Mosquito being a high-temperature hotend, it can most definitely print PLA. In fact PLA is the second most common filament we print internally, after PA.

Generally, if users are having jamming issues with the Mosquito when printing PLA it can be quickly remedied by adjusting retraction and cooling fan settings. If you hear of anyone having issues when printing PLA, please have them reach out to us. We're here to help solve problems.

@grizewald thank you for sharing your experience. Blocked airflow can certainly reduce the effectiveness of the fan. We would recommend keeping any airflow path, whether for hotend cooling or part cooling, as clear as possible from beginning to end. Turning the hotend 90 degrees sounds like it may resolve the issue as well. If you have specific questions about the way to optimize your setup, please feel free to reach out to us at info@sliceengineering.com, or speak with one of our support agents on our website.

@smece hopefully most have not had these issues with the real Mosquito. But if they have, we are certainly here to support our customers and will provide assistance with troubleshooting, or replacement hotends if that was required. Part of the cost of a legitimate product is paying the customer/technical support staff to provide lifetime support after the sale. The cloners don't have those costs.

Retraction length varies based on filament type and printing speed, but our general guidance for direct-drive extruders paired with the Mosquito is to set retraction to the same distance as the diameter of the nozzle you are printing with.

Ex: when printing with a 0.4 mm nozzle, set the retraction distance to 0.4 mm in your slicer.

For Bowden setups, the length of the Bowden tube heavily influences necessary retraction lengths and will require some tuning. We recommend halving the retraction setting used with your previous hotend (before Mosquito installation) and tuning from there.

Those lower retraction distances are the result of a well-defined melt zone with a sharp transition from solid to liquid plastic. For longer/larger print jobs this actually helps to reduce the time of the print substantially.
