may I ask how many axis it will support ?
and is there possibility of simultaneously movement at least 4-axis , better if 5-axis ?
and what kind of surface toolpaths generator will support nurbs or mesh ?
We are planning dual control system, for the fast speed movements we are going to use patched tinyg. (which support 4~6 axis)
For calibration, auto tool change and probe we are going to use internal pulse generation.
We realize without our own cam software it is not possible to progress well. So we will generate toolpath using STL (mesh) as input file. (Probably the hardest part of the project)
I have plan to push nanodlp a little bit further to make it easily integrated with other hardware so adding platform movement and other function will be easy for our CNC project.

that is right choose , cnc staff is past day stage
for guessing what I talk about look please my story of I create the first 5-axis jewelry wax mill in the world

my post about encoder in 2010
( somebody connected the encoder to the stepper motor?
as far as appropriate?
is from this sense when uprovlenie MACH 3?
say that the MACH 3 may show only the position of the axis but offset deviation nebudet, true or not?
or I misunderstood something?
podskozhite at Covo have experience with encoders
experimenting with stepper engines and having experienced at least 5 different dvigoteley, prishol to the conclusion that the least noise with the Chinese controller
Japanese hybrid engine company SANЁ ....
but those that were with me okozalos small in moshnosti of 1 A and 5.2
therefore, to pass on special stock markets took a 3 hybrid shagovika the same firm is larger by 2 times and 2.9 and in addition to everything with
established opto encoder
but that's no disk imaging on them there
an Internet search returned no significant results
only to find out that he had to drive 200 slots as many as steps per revolution of the engine and how many volts connecting etc.
no disk imaging
here and decided that once hung on the Japs shogovik encoder means it Harashi and you can dig in the naprovlenii
DC's little doubt at the expense of accuracy of this Divays
If the authorization of 200 strips per revolution it therefore can only look at the full step
What, then microstepping with 1/16 as it will show the axis position at this resolution? )

so I recommend to you download trial version of any of CAM, bring your model , and try to make toolpaths for understand how much is headache.
in this case may be you change your mind to the other side as I do .
after nanodlp I recommend you to look at direct metal laser sintering (DMLS)
I think this is future of manufactory .
but not CNC

Good question.
Our target is to have stone and wood cnc and maybe metal one.
We will have following features or differences to currently available solutions:
* Auto tool change hardware and cam support. (https://hackaday.com/2016/06/20/hackada … l-changer/)
* Low cost mostly software based probe
* Image processing to automate tasks + fault detection
At the end we would like to have high quality, low cost, fully automated cnc platform. With everything integrated.

as my experience the most difficult part of CNC is to calibration , for get all axis came to one point , in hobby cnc it is nearly impossible

second
software has to have kinematik generator , for predict crash axis

and one more question , what platform it will belong windows , mac , linux?
just keep in mind , the most fastest toolpaths cam software at the moment is Deskproto.
but it is not supported simultaneous movement of more than 3-axis XYZ.
only indexing movement .
the other one as MADcam or RhinoCam is extremely slow , in my opinion

It will be cross-platform but we will focus on Linux version.
At least for the early version it will be 3-axis + table tilt from sides. Math for tilting spindle is relatively easy, also additional axis on spindle arm is not hard but too early to talk about them. From hardware perspective both will be costly.
