It has been awhile, my Herculien still going strong but I am only using it to print large items with a 1.2mm Volcano nozzle. Needed a smaller printer and this printer started as a Cetus printer. It is a great little printer for what it is, but I needed much more customized settings, heatbed control, the electronic endstop was unreliable. Gutted the electronics, installed a Aero Extruder at first and that was a disaster for me anyways (inserting a new filament was a nightmare) , replaced with a Bondtech BMG extruder (I should have started with it in the first place) added on a E3D-V6 hot end. Gonna try .25mm nozzle, been playing with .4mm for now. I used my spare Azteeg X3 controller with TMC2208 drivers (super quite, fan noise only during printes). Changed out the hot end fan with a 40mm fan. Attached an Octoprint/Raspberry Pi with a cam mounted to the Z axis. If anyone is interested in doing the same thing, I can post the printed files for conversion.
Happy Printing
