@peirof I built an enclosure for my printer which is largely airtight. All my filament is stored in that same booth. I use cheap dehumidifiers of the type which use Calcium Chloride. Looking at the amount of water produced, I'd say they do a reasonably good job. I plan to install circulating fans at some point, which should improve the efficiency. I have an ESP based temperature and humidy sensor in the garage where the printer booth is situated as part of my growing home automation system, and also plan to fit another inside that booth. Then I'll be able to measure the humidity inside the booth and see if an electric dehumidifier would be worth the expense.
I think I have solved it .... it does not seem to be a problem in the configuration, I think it was simpler .... I use all metal Heatbreak, because it seems that the PTFE tube did not fit into the Heatbreak, by a few millimeters.
cap, now everything makes more sense ... while I had to extrude forward, it worked ... the moment I had to do some retraction or stopped extruding, the material accumulated in those few millimeters that the tube did not enter PTFE, plugging the extrusion ... and incidentally towards me remembering all their dead ...
@philn Late to the party as usual!
I have a Railcore ZLT which is CoreXY, a Voron V0.1 - CoreXY and when the Railcore team release the BOM for the Mini, another CoreXY.
As @Phaedrux mentioned iirc, static XY and a separate moving Z.
Personally gone off of the Voron2.4 and have stripped it down to either rebuild as something else or sell. Personally do not like XY&Z on 4 rubberbands!
Footnote for pedants: it is sometimes said that person is "under strain" but this is technically incorrect. A person can be under stress or exhibiting strain.
In the good old days (before Amazon) I once tried to get a bookshop to order 'Roarks Formulas for Stress and Strain' (which is a standard structural engineering textbook) and the assistant outright refused to search for it under engineering, insisting on looking in psychology and psychiatry and related fields. They couldn't find it there in the catalogue so maintained they couldn't order it. I gave up, and found it on the shelf in a better bookshop in a more academic city.
Just want to tell the outcome:
cleaned the bed with 95% IPA one and then printed the first layer with 10mm/sec for 3 parts one after over.
These two steps (especially printing first layer slow) made THE difference!
Had trouble with rest of the post, because of 'Post content was flagged as spam by Akismet.com'
Even if you had any clogs, the grub screw mounted heatsinks can be more easily removed, without risking to unscrew the heatbreak from the nozzle.
Works with a 50x50x10 fan (2,4W) so far and no specifically designed fan shroud.
So if anybody is thinking about a 5in1out hotend, this might be a good start.
I tried with direct drives at first (see attached pic, don't get fooled by the printing time, eeprom was deleted inbetween)
Second pic shows the bowden setup, which is easier to work with and requires no adapters.
