Can you print at low speeds with e3D Volcano hot end? The e3D volcano features an extended heater block of length 20&nbsp;mm with the cartridge heater running parallel to the filament.

The purpose of this is to increase the speeds at which filament can be printed (of course the extruder and other factors may still be limiting factors).

My question is how capable would this heat block be of printing at slow speeds with a 0.4&nbsp;mm nozzle?

Is printing still possible at lower speeds or is the filament heated too much that jams occur? Is the retraction performance okay?
Speaking from first hand experience running a Volcano hotend, mostly using a 0.6&nbsp;mm nozzle, but I have used 0.4&nbsp;mm as well. I can't really complain about any lower printing speed limit (low speeds are usually a solution to high speeds problems for me).

Just for completeness: I am using a DaVinci 1.1 Plus with custom firmware (modified Marlin) and an E3D Volcano hotend. No problems with the nozzle, clean prints! Note: I am using the Titan Aero as extruder but not using the included pancake motor! Went with the original motor of the DaVinci.

And as always: the parameters are key! Given a bit of tuning you can get amazing results! For PLA and ABS I can work without stringing. Although ABS seems to be prone to pitting (slight underextrusion at start of path). TPU and other flex are sometimes a bit of a challenge, but that's mainly due to my own lack of experience there.

The one important caveat here would be to also reduce the nozzle temperature. A possible theory here might be that the filament has more time and surface to heat up.

(Sometimes I go as much as 15&nbsp;°C lower as compared to normal/high speeds! Usually lower speeds means small pieces for me and in term means a limit to the layer cooling time.)
