HICTOP Direct Planetary Drive

thingiverse

This is an assembly that holds my planetary extruder in a direct drive configuration. All of the hot end parts are standard parts that come with a hictop printer. It eliminats the bearing holder blocks. Instead, the linear bears snap into a printed bearing holder. This assembly is very minumal and light weight 2018-05-25 - New version of extruder bracket that holds cooling fan more securly and pushes fan out to allow x axis full travel. Created new ring fan duct with an air blade style output. Fan duct blows less air at the nozzle allowing higher temps to be maintained with higher fan speeds. No supports are required to print this new fan duct. I used a brim to help it stay on the bed 2018-012-15 - Upload latest version compatible with version 7 and 8 of planetary extruder. Old version is still availible for download in a zip file. New version has many benefits. 1. extruder assembly secure much more rigidly to bracket and is able to slide forwards and out for service 2. Fans are attached to the front of bracket on sliding dovetails allowing easier removal for service. 3. Redesigned cooling fan duct smaller and without a full wrap around design. Did not really find any advantage to the full wrap around and found it abstructed the view while trouble shooting a print. 4. Added mounting point just behind hot end for mounting a small block style induction sensor. Before I was using a direct contact method of bed leveling by running the z-end stop signal through aluminum print bed and nozzle. I have found that the induction sensor is almost as precise and certainly a lot more hassle free(no more having to try and make nozzle spotlessly clean before probing).
