get_cap_sensor command not working with SENTIO V26 #53
Description
I just updated to SENTIO V26, and the command 'get_cap_sensor' is not working anymore, if I understand correctly the structure of the command changed. This is the function in the library:
and this is the programming manual entry:
When I run the function as is, I get:
and if I print the 'tok' variable I get a list with a single element: ['545']
It looks as if the new implementation is querying a single cap sensor at a time, whereas the old one always queried both east and west.

Thanks, your analysis is correct. Since SENTIO 25.2.0 siph:get_cap_sensor without a position argument returns only a single value (the West positioner), and 26.0 changed the number format from 545.0 to 545. The Python library was not updated for this and still expects two values, so the current release (25.2.1) will fail against any SENTIO ≥ 25.2.0.
We will fix get_cap_sensor in the library to use the per-positioner command siph:{stage}:{position}:get_cap_sensor and publish a new release. Until then you can query each sensor directly via prober.comm.send("siph:east:get_cap_sensor") / siph:west:get_cap_sensor and read the response with Response.check_resp.

excellent, thank you!

I have created a new official release. This release will require modifications to existing scripts since it now copies the remote command api for siph.
Here is the migration guide:
prober.siph.get_cap_sensor() -> prober.siph.[top.]east.get_cap_sensor() / .west.get_cap_sensor()
prober.siph.get_fiber_length(stage, probe) -> prober.siph.[top|bottom].{probe}.get_fiber_length()
prober.siph.set_hover(stage, probe, gap) -> prober.siph.[top|bottom].{probe}.set_hover(gap)
prober.siph.coupling(probe, axis) -> prober.siph.{probe}.coupling(axis)
prober.siph.get_alignment(probe, fiber_type) -> prober.siph.{probe}.get_alignment(fiber_type)
prober.siph.set_alignment(probe, fiber_type, coarse, fine, gradient, rotary)
-> prober.siph.{probe}.set_alignment(fiber_type, coarse, fine, gradient, rotary_gradient, focal_gradient)
prober.siph.set_origin(probe) -> prober.siph.{probe}.set_origin()
prober.siph.move_origin(probe) -> prober.siph.{probe}.move_origin()
prober.siph.pivot_point(probe) -> prober.siph.{probe}.pivot_point()
prober.siph.move_nanocube_xy(probe, x, y) -> prober.siph.{probe}.move_nanocube_xy(x, y)
prober.siph.get_nanocube_xy(probe) -> prober.siph.{probe}.get_nanocube_xy()
prober.siph.get_nanocube_z(probe) -> prober.siph.{probe}.get_nanocube_z()
The stage and probe selectors are no longe a function argument but part of the command hierarchy. Stage selector (top/bottom) probes is optional. If it is omitted top is assumed.
