hello!
I have announced it earlier, and I requested some help here from the forum (thanks for that, btw). as of today, my controller project for large, heavy mounts is a beta, especially as I have documented it heavily. In short, TSC is a telescope controller based on a Raspberry Pi 3 for rather large and heavy telescopes. It utilizes INDi for autoguiding and has a few other nice features like autonomous WLAN, a wireless handbox and TCP/IP based telescope control for tablets and smart phones. the project homepage is tscatm.wordpress.com/ - here links to github and other ressources are available. and - for those who are really interested - there is a beautiful manual available: tscatm.files.wordpress.com/2018/03/tscuserguide2.pdf

hi!
yes, I know, but something like that COULD be a reason ... where does the telescope actually go to (in declination) when you enter a negative declination???

hi!
i don't know whether that is the problem, but i ran into something like that when programming my own controller (which also interacts with sky safari). sky safari sends strings as coordinates, like
-00:17:56# for mintakas declination
this is a string, a series of characters. on the program side, you have to convert this to a number for hour, minute and second. converting the first characters "-00" to a number results in the number 0 ... there is no negative zero, so this does make sense. and voila - the coordinates are wrong, it is now 0°17'56''. as this happens only below the celestial equator in your case, something like that might be your problem. however, porrima has a declination of -1° something, so it might not be exactly that problem, but it may be related...
just my guess...

ok - three months later, v. 1.4 of the TSC-pcb hat is now fully working:
- realtime clock
- usb/serial converter for old school lx200
- optocoupler for relasing a DSLR
- input for temperature sensor
- freely configurable ST4 via the mini
- SPI control over the focuser board
wohoo

hi!
had my 120MM running all night with the new 1.6 version of INDI on Raspian Stretch,; the camera was polling an image every second. No problems.

hi!
good news, especially since the old interface did not support syncing ...

hi!
the next months will see a release of TSC, I am still working on the PCBs and i need some further testing of the autoguider function - github.com/selste/TwoStepperControl/wiki
stepper motor encoders are not yet supported, but it is no problem to add them. why do you need them? I drive a 350 kg telescope without encoders and GOTO works fine. TSC includes INDI for gudiecam-acquisition. control takes place via LX200. functionality includes:
- Internal editable catalogs and LX 200 support for kStars, CdC, stellarium and SkySafari
- Internal WLAN (opens it's own hotspot if no router is within reach
- LX200 via USB and WLAN
- ST4
- INDI interface to guidecameras and autoguiding
- DSLR control and dithering
- realtime clock
- support for two additional focuser drives
- Bluetooth handbox

hi!
direct encoders are no issue as there are readymade phidget interfaces for those. however, I don't need them. as for encoders on the axes, something more sophisticated is necessary...
maybe an option for later :)

... and everything has a revision - so this one has now optocouplers for DSLR and ST4 instead of the venerable ADuMs i used in the first effort, and to the left is a homebrewn auxiliary motor board that drives two steppers for motorfocusing. these are by far not as powerful as the Phidget boards (the drivers are cheap A4988 drivers, and the controller is an arduino pro mini), but for a focuser they are more than sufficient ...
