BTW the S6 v2 StepStick driver sockets SLP pin (where 5160 CLK pin plugs in) is pulled up to 3.3V through a 10k resistor according to the schematic. Those TMC5160's better have that CLK pin grounded o

It'll automatically set a safe low current if omitted, I'd expect the motors to still work though. That said, still needs to be corrected.

I.e. say you call the S6 pins P1,P2,P3,P4. These are all ok... P1 to B1 P2 to B2 P3 to A1 P4 to A2 or... P1 to B2 P2 to B1 P3 to A1 P4 to A2 or... P1 to A2 P2 to A1 P3 to B2 P4 to B1 or... P1 to A1 P2

Good. Good. Good. So pins in order 1,2,3,4 and pins 1,2 go to one motor coil lead ends and pins 3,4 go to the other motor coil lead ends. Which coil A or B and which motor coil lead end 1 or 2 is irre

The motor current should be set as follows AFAIK (likely to be a good match for 1.7A rated motors)... #define AXIS1_DRIVER_IRUN 1000 // OFF, n, (mA.) Current during tracking, appropriate for stepper/d

Info. about the power supply also. Volts and Amps it's capable of.

Shunts seem right. Probably the 5160's CLK pin state is ok? No info. that the drivers in question are in the correct sockets. No info. on exactly what the stepper driver section of Config.h looks like

Says he has GPS so yes to everything except the UTC offset... which isn't really important internal to OnStep.

Not how it's typically done when starting out. Using OnStep

That may very well be the case, the Wiki advice is generic.

Hint... the master branch allows switching between Alt/Azm and equatorial modes at runtime.

I would focus on getting the TMC drivers working. Make sure the S6 board shunts (connecting the SPI signals to the driver pins) were positioned correctly (follow the S6 Wiki.) Make sure they are the c

No. Probably you really should be using the beta branch, not the master. The master isn't well tested at the moment. Probably AXIS1_STEPS_PER_WORMROT should be 0 (the default.) Definitely just saying

Is this line from the CNC3 pin-map relevant? #define Axis1_EN 12 // Enable [must be low at boot 12]

That's a nice bit of information to see, wasn't really sure that was the case.

Data format is completely different, no way.

Also, if PPS is enabled OnStep will wait for the PPS signal before pulling the site/time info. from the GPS.

You can use a hub but it's not usually required with this new driver set.

The latest driver supports release-3.16, what you do is up to you.
