WIP CoreXY with heated chamber
-
IDEX - that looks like a proper way to do it, I even will not lose any building volume as I do have good free spacing on a side! Thanks for a suggestion. I investigated a bit and found Dyze hotends exist with liquid cooling addition, sadly I didn't find anything similar from E3D. Do you maybe have a suggestion of another single liquid cooling hotends?
Haven't look yet for a CoreXY conversion to IDEX, but it should be doable with just Duet wifi what I have now?

E3D doesn't sell a water cooled version of the V6 (except for a water-cooled version of the Titan Aero), but if you search "water cooled e3d v6 heatsink" then there are a few hits, such as this one https://youprintin3d.de/hotendszubehoer/e3d/wasserkuehlung/792/water-cooled-heatsink.html. I've no experience of either those or the Dyze hot ends.
An IDEX printer requires at least 6 stepper drivers, so one more than you have on your Duet WiFi.

Oh yes I see, will need an extension board
Thanks for a E3D water-cooled heatsink! -
So far I am having decent results using a Chimaera for different support material. I placed the support nozzle ~30u higher than the main nozzle, which prevents dragging. Extensive cooling and wiping during a toolchange takes care of the ooze.
It is slow as hell though. Idex or toolchanger would be way better.
-
Can you post your tool change files, please?
-
Sure: https://www.icecoldcomputing.com/directlink/3dprinter/Dabit3D_config_10feb2020.zip
Mind you, these files are a work-in-progress also. I reworked the tpostX.g files yesterday to improve the wiping process, and did not test them yet.
-
Thank you! I will give a try to it.

Some updates on work in progress machine
At this moment I am - working on lighting, sealing the chamber with aluminum foil, figuring out the door mechanism, wheels, and feet! Eventually, it became direct drive extruder, much happier with results!

Nice! Looks like you're getting great print quality, too.
Does that center frame member on the top of the machine interfere with the extruder carriage cables/hoses? It looks like it might depending on the position along the X axis.
-
Thank you!
Yes indeed it looks like it might, but I moved it to the right so it does not interfere. In the end, I will remove it, otherwise, the cable hose and liquid hose will be in touch with top cover and probably will mount cable chain.
The big thing I want to mount and test is a heated bed, but with this world situation of Corona I am already in a delay of 3 months...There is my latest benchy
-
A bit of safety first! Kids around...
-
Its also visible how cantilevered bed is quite stable.
Print test - 100mm/s internal perimeters, exterior got 77 mm/sec. -
And there is lighting, and top covered. Still waiting for a heated bed to come...
-
Do those print cooling fans actually move any air? Axial fans don't usually work against the back pressure that any sort of flow restrictor produces.
-
They do seems enough, but I must say they always on 75% to make me desirable result, meaning very loudly also :)).
Will you suggest to change on something else? I fully am open to comments and experience! -
Radial blowers move more air against the pressure produced by flow restrictors. This type of thing usually works better: https://www.amazon.com/FYSETC-Cooling-50x50x15mm-Radiator-Accessories/dp/B07NTKG9K4/ref=sr_1_15?crid=O279YCVTBA45&dchild=1&keywords=radial+fan+24v+for+3d+printer&qid=1585683940&sprefix=radial+fan%2Caps%2C168&sr=8-15
-
Thanks! Ordered! Need to figured out the connection method, as I want to place watercooling block later on the extruder motors... It doest not matter the position of how I can place radial fans?

@felt342 I don't think the orientation of the blower matters, but probably best to check a data sheet if there is one.

@mrehorstdmd
I see! I will design something and will post here to have a look.Industrial 3D printing service in the Netherlands - gagatstudio.com

@felt342 The cyclops hotend by E3D may be a good option for IDEX since you already have a chimera. you can also water-cool that.
