Been playing with tiny 0.25mm nozzles and 0.075mm layers. This is a tiny octopus.
I am assuming you are using the wades cold end, i don’t think it would be possible to get such a low flow rate out of a direct drive extruder…
Yep it’s the standard Mendel90 edition of the geared wades extruder. The big gear barely moves at these flow rates, I agree with you on possible issues with direct drive resolution but have little experience with it myself - geared till I die!
@Sanjay_Mortimer The more i look at it, the more i agree, geared extruders just work better (except at crazy high flow rates, but i don’t print at high speeds). When i get adventurous and start assembling a multi-head system, i think a direct drive cold end with a huge nozzle, and a geared Wades variant with a tiny nozzle would be a wonderful combo, you need the gear reduction to get a really precise flow rate, and to deal with the high pressure, but for the large diameter (i am thinking .8mm or bigger for infill and really rough prints), the direct drive is just much simpler to work with.
Hmmm. Now I am interested. I have a direct drive with an E3D and run a .25 nozzle. Might try this print tonight.
@Sanjay_Mortimer what scale?
30% on this one as I recall. With 0.075 layers.
I tried running it last night @Sanjay_Mortimer . I can cold run the extruder, but trying to print the transition zone got me. Heat was creeping up. Too slow, my filament was swelling in the tube between the heater block and the fins. Tried running faster/hotter but force was too much.
May strap on the Gregg’s and try again.
