BUG: Cannot create Thorlabs.KinesisMotor from a serial number

[kadykov]

Cannot connect to a Thorlabs KST101 motor controller. pylablib.devices.Thorlabs.list_kinesis_devices() detects a correct serial number, but creation an instance of pylablib.devices.Thorlabs.KinesisMotor(sernumber) crashes with ThorlabsBackendError: backend exception: 'read returned less data than expected'.

Minimal example to reproduce:

from pylablib.devices import Thorlabs

devices = Thorlabs.list_kinesis_devices()
sernumber = devices[0][0]
print(sernumber)

Thorlabs.KinesisMotor(sernumber)

Output

Unfortunately, the traceback got truncated in the middle, but it looks like the device is simply not replying to any commands (since this is the first time the code expects a reply).

To double-check, could you run the following code

dev=Thorlabs.BasicKinesisDevice(sernumber)
dev.blink()
dev.get_device_info()

and check whether

• it passes or raises an error
• the controller reacts in any way (e.g., turns on its screen light)?

Also, just to check that it's not a hardware issue: can you connect to the same device using the Thorlabs Kinesis software? And have you tried pylablib for other Kinesis devices, connected to the same PC, if you have any?

You are right, it was just a problem with the controller itself. A proper reboot solved the problem. It seems that a quick on-off power cycle does not actually reboot the device, it is necessary to wait at least 5 seconds before switching it on again.

Thank you very much for your help.
