necessary electronic components?
-
My name is George and I want to build a 3d printer with the following features: Fixed heated printing bed;
Z axis driven by 4 nema motors 23 2.5 A, with self leveling;
X axis driven by 2 Nema motors 23 2,5 A a Y axis with single Nema 23 2.5 for print head.
I would like advise you what electronic components in your offer I need to perform the tasks listed above.Thank you ,
P.S : I apologize for the way it is spoken, English is not my native language

for nema23 i would advise the duet 3. (https://www.duet3d.com/Duet3Mainboard6HC)
however the duet 3 only has 6 stepper motors and you will need at least 7 (assuming one extruder)
the duet3 expansion board https://www.duet3d.com/Duet3Expansion3HC is open for pre order.
or the https://duet3d.dozuki.com/Wiki/Duet_3_Tool_Board is comming soonwith 2.5A motors you might just get away with a duet2 + duex5 expansion board.
if you can wait a bit i would go for the duet 3. or you could put the x axis in parallel to begin with. that would allow you to run it on one duet 3.
-
I count 8 needed however I think you may be better with just 3 for the Z X's in Parallel as Veti suggested one on Y and another for your extruder making 6 or you could go with a Duet3 main board and then hopefully by the time your ready the Tool boards will be available.

Thank you all for the quick response.
I would not want to give up the four motors on the Z axis ( it would affect my design. ), I want a process of self-leveling the printings as precisely as possible, that's why I want an electronic system to do this.
Regarding the X axis I could put both motors in parallel (I cannot give up an motor, it would affect my design.
P.S: there are 8 motors in total: 4 Z axis, 2 X axis, 1 Y axis, 1 extruder -
So the best choice for my application would be duet 3 tools board? other than that, why would I need more? I would like a list of absolutely all the necessary electronic components, I apologize, I am new to the field.

Three is more precise than four.
This has nothing to do with Duet or even 3D Printers. Moving a plane with four control points is what is called "over constrained" in mechanical engineering. Moving it with three is neither over nor under constrained.

@george1982 George the tool board is only a single driver which is designed to sit on the extruder head itself (Simplifies wiring etc to the extruder but that is just a good by product) to get the 8 motors you need you would be looking at a main board and a 3 driver expansion board (you could also use a tool board for the extruder) you would have to be careful which motors you use on the expansion boards mind as I believe they have lower capacity drivers on them also why do you want to use a N23 on the extruder seems a bit excessive
-
@Dougal1957 the extruder is hemera and use a nema17 , only for the axis is nema23
-
@george1982, the tool boards are designed to mount on the Hemera.
