Your manual slewing issue seems to not only happen to you, see:
onstep.groups.io/g/main/message/54120?p=...%2C2%2C0%2C101217608
Have a look on lessons learned on
onstep.groups.io it can help to read users feedback.
In short, many people experience problems with "Terrans" but some return successes and even tweaked it.
latest firmware is: On_Step 10.17.f so many things could have changed between the two versions
Now to go ahead on your side I believe it is better you ask the help of a friend that has knowledge in electronics and programming to help you.
No way to get help from Terrans and from my side I am willing to help but without knowing your configuration it is just guessing.
<strong>Testing:</strong>
Testing a new OnStep directly in field is like plying roulette ...
Testing should be done step by step:
1) bench test: only connecting OnStep to computer but not the mount, run Kstars and using device manager connect to OnStep enabling full debugging to file and then run all tests you can do, "Connect/disconnect, Slewing, Syncing, Tracking, Parking/Unparking, Focuser operations, ... ) and then analyze your logs
2) If bench test are successful then connect the mount to OnStep (in house) and restart the same tests and see what is going wrong and see the logs
3) if everything is OK at this stage then you can reasonably start testing in field, if not you have to debug the stuff! that is look at Debugging and Tweaking
<strong>Debugging and Tweaking:</strong>
Check which version of hardware and firmware you have:
1) you already detected OnstepX 10.12e
2) Open you OnStep and identify: (<strong>
with detailled pictures</strong>)
- Which Motherboard you have
- Which Processor is installed (should be ESP32 Wroom 3)
- Which drivers are installed for the 4 axes (DEC, RA, Foc1 and Foc2) (TMC2209?, TCM2130? ...)
3) Download OnStepX (git clone
github.com/hjd1964/OnStepX)
4) Install arduino IDE (
www.arduino.cc/en/software and download Arduino IDE 1.8.1)
5) based on the above detrieved informations edit the config file (see
onstep.groups.io/g/main/message/53284?p=...0%2C2%2C0%2C97751477)
6) Compile and upload the firmware to your Onstep (again procedure depends on above informations)
7) then do testing again.
Sorry may be this does not help a lot but it is the only way to success in my experience.
