Help with components for high resolution delta
I have a Duet modified Tevo Little Monster, a medium big delta...
But I d like a printer for high resolution.
The objective its accomplish layer heights of 0.02 mm, and similar X and Y resolutions...
I have see, this printer
And some news
This will be a very good option... Only rest mod to Duet.... But I can't find reseller...
How this printer its unavalaible, the next options it's a DIY printer.... And need help with components...
¿Can you help me?
01 Kind of printer... In another post in this forum, have answer, that the best kind of printer for precision it's Delta type... But the printer of up link, that reach 0,02 layer, its a core Xy... What it's the most precise movement system? (delta suposse)
02 Frame, I have see delta frames in aliexpress, there is a lot of them, but... What frame for a high resolution delta... With low volume... Aprox 100 mm diam X 200 mm tall (aprox)
03 Movement mechanics. I have see that there is 0.36 deg steppers... The problem, the price.
- Movement mechanics. For more resolution... Use linear guides, no belts...
Please.... Need recommendations for components... Another option it point me some link, that someone that have/sell this kind of printer... Like link in top of this post...
This is a open post, its the initial idea...

The railcore 300zl printer has .01 layer height ability, I just don't know what the x & y resolution is but it supposedly can print very well and fast as well.
and a resolution of 0.01 mm per layer, it's incredible ... this makes me question the requirements. What makes me wonder about the specifications of that machine is that it can get to print that layer height ... because, I had read, that the optimal layer height is between 25% and 75% of the Nozzle used ... and in the characteristics, the thinnest nozzle is 0.4 mm, which would limit the layer height to 0,1 mm, x10 times the specifications ...
But it's an option that I like ... what I do not like is the price ....

i am seeing that movement system of printer, its not the bigger limitation, in general, for resolution....
The bigger limitation its the extruder system, no?. I have read, that the layer height its recomened 25% to 75% of nozzle diameter... in this moment, i use a 0,4 nozzle, that implies the maximun recomened Z resolution its 0,1 mm.
The printer i have attach link, in previous message, can mount until 0,12 mm Nozzle, teorical, can reach 0,03mm layer height, and they go further, saying can reach 0,02...
If i have clogs with a 0,4 nozzle.... with a 0,12 mm nozzle.... jejejejeje.
But... i want try.....
It might be possible to build a FDM printer that can do 0.02mm layer height. But I don't think you will achieve 0.02mm real (as opposed to theoretical) X and Y resolution because of the difficulty of controlling the extrusion width. If the parts you want to print are small, perhaps a resin printer would be more suitable for your application.
i have a DLP printer.... but resin, its not cheap.... and hard to handle....

IMO, tiny layer heights will need a tiny nozzle diameter which in turn will mean tiny extrusion amounts, which in turn will mean very high gearing for the extruder. But even so, trying to accurately dispense say 0.1mm wide by 0.02 high from filament that is 1.75mm diameter is going to be next to impossible because the forward motion of the filament will be so small. It's a ratio of something like 2.4mm^2 for the filament going in vs 0.002 mm^2 for the filament coming out. So you'd probably need to start with filament that is around 0.3mm diameter to have any real chance I'd have thought.
E3d sell nozzles of 0,15 mm x 0.25 = 0.0375 mm of layer.... 0,2, no. but 0,3 mm its rearchable?
The printer i have, its a delta... and uses G.T.2 Belts/G.T.2 Pulley/Nema 17 stepper (1,8 deg)
In this moments, i have configured in 1/32 microstepping
1 - Where i can find the maths to know how many distance carriges moves (In axis in vertical), when stepper turn a microstep (1,8 deg / 32). No?

This is really simple: 1/steps_per_mm on the axis
