This post is a result of a different thread hijack mentioned below. The intent is to follow up on this particular issue with this biqu line of direct drive extruders that many of us have.
The H2V2s is at a great price point but the gearing sometimes has issues and it is flow limited at 12 mm3/s. The gearing issue may be from a lack of lubrication required for an all metal drivetrain. It may also be from a loose-fitting bearing. Fitting a stainless washer in the wear spot on the tension lever is one way to workaround the issue. As is a small piece of teflon tape.
The H2V2s lite has the same gearing but a proprietary M4 threaded nozzle on its custom 45 mm3/s heat block, so finding 0.6 mm or hardened nozzles in either size is both expensive and rare as the standard nozzle thread is M6.
Based on the suggestion in Matts thread, there is an opportunity to improve the “s” model throughput and the lite model nozzle scarcity by fitting it with a volcano heat block.
How is this done?
What parts are necessary?
How well does it work?
I hope it works out well for you! It was worth it to me just to be able to swap nozzles and such. You will have to adjust your Z offset and stuff. I believe that block/nozzle is a few mm longer than the BIQU one.
I just had @CarmenJ check and she can get everything but the adapter on our “normal” amazon. IDK why its different on my business amazon account. makes no sense
