Tough.
The world will not dance to your tune. The plans are FREE, for heavens sake!

It never ceases to amaze me that someone says something which clearly indicates they didn't think before they responded or lack the faculty to see value in an offer.
RCaffin, why would you inject this nonsense?
Are you really that clued out that you can't understand the benefit provided by my friends offer if the files are in eagle format?
Since you seem pretty clueless I'll clarify it for you, no eagle files and my friend wont produce the boards inexpensively, you don't have to be a rocket scientist to understand this, just have some common sense and the ability to read.
Since it is doubtful you will make an offer to produce the board at a reasonable cost I fail to see how interest will be maintained for a product that is not reasonably priced when there are full and complete retail solutions at a fraction of the current cost.
For $62.00/pc I can buy a 6.5A/80V (AC 20V-80V / DC 20V-150V) stepper driver including the heatsink with an MOQ 10pcs and since the current cost is so high for an incomplete solution it wont help it survive past the OP's personal project and even he realizes this.
So, you are saying people should buy the product despite it's inflated costs just because you think they should, yeah right, good luck with that logic.
In closing, I would like to thank you RCaffin for informing me that the project doesn't need any help to produce the boards at a reasonable price and that it can live with the over/double priced product which doesn't make it an affordable or reasonably priced solution which in turn contributes to it's demise.

Re: Open source low cost servomotor controller
I bought 5pcs of 15A/60VDC (STM32F103TBU7) based servo drivers at $38.00/pc and the heatsink requirement is nothing more than a small strip of 1in wide aluminum flat-stock due to the very low IRDs of the FET's used and this price was based on a run of 200pcs.
While I have the eagle files for this driver, making more of this driver is not an option because what is lacking is firmware and the one person who has working firmware is no longer sharing it after others like yourself decided you didn't want him around here contributing to any projects.
Basically what I see is a lot of people like RCaffin who are actively sabotaging viable projects and products and for the life of me I can't understand the logic which dictates that an inexpensive servo solution should not be available to the home/hobby user but it appears that many people don't want it as they make efforts and expel energy preventing it.
Re: Open source low cost servomotor controller
I couldn't see it anywhere but are you planning on producing 3 axis boards?
Very cool looking project, major props getting it out there!
cheers, Ian

Right?
Heaven forbid that someone should use a professional EDA package instead of the industry's equivalent of Duplo.
In a more bridge-building, happy light, though, here's a suggestion:
mcdowswe, if you have the time would you mind adding some files to the github project? In particular, if you can do a generate & export of gerber files for the PCBs, anyone can get them made pretty much anywhere. A PDF export of the schematics would mean those without Altium would also be able to trace things down. If all anyone wants to do is make boards per your design a little bit cheaper this'd be all they needed.
And it would mean that anyone who wanted to modify the design for themselves would be able to create (and, obviously, publish in the spirit of open source) an Eagle format mirror of the design files.
Re: Open source low cost servomotor controller
Hi websrvr
To explain: this is a hobby project one person is running, and he is running it HIS WAY, as is his right.
It might fly, or it might not. It might be too expensive, or it might not. But it is HIS project.
Since it is HIS project, he is at liberty to publish how he wants and as much or as little data as he wants. That is HIS choice.
For anyone else to come along and try to take the project over and dictate how data should be made available is not only wrong, it is impolite and futile.
My 2c

Hey, thanks!
So yeah many people have requested a 3 axis version, and the plan is to do that for v4. I have already identified a microcontroller that has the peripherals required for that.

Re: Open source low cost servomotor controller
So on the topic of websrvr's offer and the resulting discussion:
I am intending to make the price point lower than $96, as I already stated previously in the thread, the target price is around $50.
I have many different options to chose from, including one guy over at the OpenPnP mailing list who offered to manufacture 50 boards for free to get the project started.
I chose to go with CircuitHub to get some prototype boards done quickly.
Can we please keep the topic of the thread about not this now?
How about: What kind of forces are required to do CNCing on your machine? Do you use leadscrews or belts?
Cheers,
Oskar

So the schematic pdf is already available on GitHub: Link.
Yeah other people have already asked for gerbers. The reason I haven't provided them yet is because there are still some bugs in the hardware design, that I hope will be fixed with version 3.1 (the one currently being manufactured). Only when I have verified that the bugs are solved will I be comfortable in recommending others to manufacture boards of their own.
Cheers,
Oskar
Re: Open source low cost servomotor controller
Champion, Oskar. And thank you for your efforts with this design - and for deciding to share it with us. Very generous of you!

Hi we use 4nm motors on our mills and lathes if that helps
