WIP CoreXY with heated chamber
-
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.
-
@felt342 I'm looking forward to the finished build! Ive also got a corexy with a chimera hotend, although I'm not going as balls to the wall as you lol. Also i like your direct drive setup. is that your design or was that available online?
Old picture. Linear rails added and different carriage design, not my designCant stop tuning wont stop tuning.

@Turbo Is that a dbot with a belted z axis? Link?
-
@Phaedrux It was a custom design my friend made. I got this printer from him. I could see about putting them somewhere if hes cool with it, as he also gave me the files, but id have to make instructions or something.
