Bummer, that. Just when you think it is safe to put down the crayons.

That's great. The enable pin setup they had was so stupid I had to add a pull up resistor to prevent the motor from melting down. Hopefully they have an updated library that will work both versions with the same instructions.

Agreed. But no, there is no such library. The Waveshare website has sample code, two versions. One version for the old board, another version for the new board. And unfortunately, there's no way to programatically detect which board is installed. It must be left as a configuration option that the user must set.

Hmmm...is there any marking on the board to reveal it's version? Or is this a "fire it up ant see" change? I don't see even a part number on the board.

I ask, because I've ordered a couple more boards for spares. It would be nice to know if they are old or new version.

Yeah, the website says the new PCBs are printed with "Rev2.1", and will be anything purchased after 2021-01-05

www.waveshare.com/wiki/Stepper_Motor_HAT

So that explains why at least two users a couple months ago couldn't get the driver to work with new Waveshare boards they just bought. Doh!

Added a fix. On the Options tab there's an option to select the board revision (don't forget to hit Save!). Hopefully someone with the Rev 2.1 board can let me know if it works.

I have two boards on the way. Will test on arrival and report.

How auspicious! As I was typing my last message, DHL was putting the box on my porch. The new code works on a Raspberry Pi4 running Ubuntu Mate 20.04. When you switch the board to 2.1, it works. When you switch to Original, it ceases to operate. I noticed no overheat issue.

... I don't know...but personally, I would have been hard-pressed not to name the buttons, "Original" and "Extra Crispy."

LMAO!

Thanks for testing. :)

I had started a topic regarding preserving the focuser position between instances of running INDI, and recovering from a crash.
www.indilib.org/forum/wish-list/9817-wis...ocuser-position.html

I learned this is something handled within the driver not EKOS. Could you look into that? Thank you.

Yes, saving the last focus position is next on my to-do list. :)

Okay I just committed a change that will save the position to a file, and restore that position on startup. To be clear, this doesn't actually move the focuser, it's the equivalent of doing a "sync" to the last known position.

Try it out and let me know how it works out for you.
