Picomotor controller model 8743-CL #89

Open alexkish opened 2 months ago

alexkish commented 2 months ago

What can I try to modify in the code to make it work with the 2-axis controller model 8743-CL?

These are the commands that work and the responce to them:

Newport.get_usb_devices_number_picomotor() 1 print(comm_backend.PyUSBDeviceBackend.list_resources(idVendor=0x104d)) [(4173, 16384, 0)]

If I execute this command: stage1 = Newport.Picomotor8742(), I get the following errors:

KeyError Traceback (most recent call last) File /Applications/xapps/miniconda3/envs/scipy/lib/python3.9/site-packages/usb/core.py:236, in _ResourceManager.get_interface_and_endpoint(self, device, endpoint_address) 235 try: --> 236 return self._ep_info[endpoint_address] 237 except KeyError:

KeyError: 2

During handling of the above exception, another exception occurred:
