DDSCV1.1 3 and 4 axis offline motion controller

[Boyan Silyavski]

I have experience with Pokeys and it didn't work well for me, possibly due to interference. As i have said in another thread, documentation is not good, leading to constant questions.

As far as the market, we have to understand that Chinese don't care at all to make a controller to our needs. Their internal market is much bigger than the whole world market for controllers!!! So don't expect wonders here. They do what they need, so until they need it, there is no development.

The big problem with them is closing even Open source which they use for free, mainly because of fear somebody not to copy what they do. As they copy constantly of course, so they fear the same fate . then comes the copy of a copy of a copy...

Boyan .. You more or less echoed my post .. in different terms, different pov.
(We both live in Spain. A visit, perhaps .. ?).

I think the chinese market is not so big .. yet .. for controllers.
Almost-all controllers today are 3d printer/router/basic laser type stuff .. very little in china. Per popula.

I mostly wanted to point out somewhat why/how every intelligent controller has issues.
And why none of them will fix most issues, in near-term.

Because it is extremely complex, 100++ issues to power of 8 modals. Plus many cascading multiples of toolchangers, kinematics etc.

It actually would be relatively easy to fix 99.x% of issues..
but would cost == 3 (extra) good programmers == 6 months, == 130k€ or so.
The interface/controller/bob market cannot afford it as-is.

Note I made no preference for any controller.
The same fixes c/would apply to mach4 (x), cncxxx, chinese xx controllers, machmotion etc.

My post was-is more market value related.
Like VC funding, that I think would be dead-easy to get (I have experience).
The "field" imho needs much more structure, and assistance from someone with it/project/sales/tech support experience.

I think the most valuable parts would be docs, reference designs, examples.

I'm nowhere as technical as you guys, but I still think that there is a lot of good stuff made in China. For instance, I have just received a typical cheap Chinese servo motor, it works beautifully, but no thanks to the instructions, they are diabolical. This is the thing that lets down so many Chinese goods, the lack of proper English instructions delivered by a technical person who understands the product and is able to make them clear even for a novice to follow.

In the end it's a lot of guess work and I bet a lot of people have been put off ordering because of the lack of proper documentation and examples. Luckily, in my case, I have prior basic experience with servos to know where to luck and what needs to be done, so I was able to benefit from an otherwise excellent product.

They could do so much better and sell them like hotcakes if they spent a few thousand dollars and hire a technical expert to put together some comprehensive instructions, but no, they won't do it, it's just beyond me!

There's a thread on MadModder about this controller, one guy has been in contact with the manufacturer and says V2 of it will be out in about a month or so.

How is the software corrected for the perpendicularity of the axes?

How is the software corrected for the perpendicularity of the axes?

As i answered you on Youtube, still not. it must be done in a mechanical way, say bumping the gantry towards mechanical end stops and then switching on the motors. I do that everyday on my machine and its not a big deal. 1 min more.

My question does not concern the subordinate axis.
The question of correcting the perpendicularity of the axes.
For example, in Mach3, this is solved through formulas.
