Hello. I am using bbd302 (firmware 010107).I have set the trigger out in the software to use the trigger, but when I moved to the stage, the trigger signal is not outputting.Is this because of the firmware not being updated?If it's a firmware issue, please let me know how to update it.

Hi, I am using a BBD301 with a DDS220/M through Python scripts. I adjusted the DDS220/M to move forwards and backwards from 100 mm to 120 mm, over 30 times. The acceleration was set to 100 mm/s², and the velocity to 10 mm/s. Subsequently, the BBD301 displayed an 'overload' message, and the DDS220/M stopped working. Were the operating conditions for the BBD301 too demanding for repeated movements? How can I prevent the BBD301 from becoming overloaded or non-functional?

Thank you for you feedback and I am sorry to hear about this. There are many possible causes for the overload error. Your application itself should not intrinsically cause it but this will depend on many factors such as load. I will reach out to you directly to discuss your application and help troubleshoot this.

I am using a DDS220/M axis with a BBD301 controller using the .NET API via pythonnet. The controller frequently shows an "Overload message" on its display and sometimes stops working at all. I used the sample code from the Kinesis getting started guide. I noticed that the axis sounds differently if I use the Kinesis software vs controlling via the API. MaxVelocity and Acceleration parameters are the same, however. What can I do?

Response from Daniel at Thorlabs. There are a few differences, the KBD101 K-cubes are all single channel where as the BBD30X can be 1, 2, or 3 channel. Also the stages that the K-cubes support are different from the benchtop devices.

Hi thorlabs, can BBD302 be used to control the galvo like GVS012?
DJayasuriya  (posted 2022-08-18 09:51:58.0)
Thank you for your inquiry. Unfortuantely the BBD302 would not support the GVS012. For the GVS012 you would need a DAQ card or a function generator. Please see chapter 4 on our manual (htps://www.thorlabs.com/drawings/ce7acd8b6476cac5-EB516D8C-E4E4-8D37-C9B7C526F0005FB1/GVS012-Manual.pdf).

I'm controlling a DDR100/M rotation stage connected to a BBD301. I'm using the "Host-Controller Communications Protocol" like described in Issue 29 (2021-10-20). Everything works fine. Now I want to use time-position arrays (commands 0x0980, 0x0983, 0x0986). But after loading the data, setting the (cycling) parameters and sending SYNCHSTART nothing happens. The stage is not moving at all. Is there a possibility to check, if the data has been loaded correctly? It's a bit unclear and ambiguously described where indices (ArrayID, StartIx, CycleStartIx, CycleEndIx) start. Are they 0-based ore 1-based?

Does the BBD302 still expose the quadrature encoder outputs on the AUX connector like the BBD202? The manual mentions QA, QB and IX/Ref, but they're not listed on the pinouts.
cwright  (posted 2021-07-15 10:26:46.0)
Response from Charles at Thorlabs: Hello and thank you for your query. Yes, this is still possible. The QA, QB and IX signal from the BBD302 are accessible through the AUX IO D-Type connector. There are differential outputs (“Digital O/P 4+/4-“ to “Digital O/P 12+/12-“) which output the QA, QB and IX signals by default.

Response from Jack at Thorlabs: Thank you for your inquiry. It is possible to read the QA, QB and IX signal from the BBD302's AUX I/O connector. There are 9 differential outputs on the 37-way D-type connector (the pairs “Digital O/P 4+/4-“ to “Digital O/P 12+/12-“).These are configurable and by default they output the QA, QB and IX signals corresponding to the 3 motor channels.

Hi, I want to trigger the controller externally with a digital trigger. In the APTUser software, I set the Input trigger on my desired trigger behaviour (e.g rel move on rising edge) and this works so far. But unfortunately I can not figure out, how I set the distance. In the manual it is written, that the last value from move_rel is used. But either in my APT based python software nor in the APTUser software I have this command. So how can I set this value?I have also tried the Kinesis software, where I also can enable the Trigger. But this did not work at all. Do you have an idea or an example?

Hello, I'm developing a python wrapper for the Kinesis C API to connect to BBD202 with two DDS220 stages in XY configuration. I had the following questions/comments.Current Setup-------------* Windows 10 64 bit* Using Kinesis Version 1.14.16 C API (64 bit)* Two DDS220 stages connected as XY to a BBD202 controller* Python wrapping via ctypes, homing and basic motion commands implementedQuestions/Comments------------------1) TLI_DeviceInfo Struct Reference in Thorlabs.MotionControl.C_API.chm file does not match the definition in the Thorlabs.MotionControl.Benchtop.BrushlessMotor.h file. For instance, in the chm file TLI_DeviceInfo has a field called "maxPaddles" which is absent in the header file. 2) Why does the example code under BMC_Open checks for BMC_Open(serialNo) != 0 to execute the contents of the if statement? Does running BMC_LoadSettings and BMC_StartPolling automatically connect to the controller?3) Without a BMC_LoadSettings call, position related functions such as BMC_GetRealValueFromDeviceUnit or BMC_GetMotorParamsExt do not work. Are there other inter-functional dependencies? It would be great to have those reflected in the documentation.4) I try to use BMC_SetLimitsSoftwareApproachPolicy and BMC_SetMotorTravelLimits functions to limit motion by the stages, but BMC_MoveToPosition function overrides the travel limits. What is the proper way to limit the travel range for the DDS220 stages through the C API?
rmiron  (posted 2019-04-25 04:27:22.0)
Response from Radu at Thorlabs: Hello, Ekin. Thank you for taking the time to bring these issues to our attention. I have relayed your feedback internally such that our C_API documentation gets improved. I will try to address your points in order.1) maxPaddles is a parameter of the TLI_DeviceInfo struct defined in Thorlabs.MotionControl.Polarizer.h. That is why it is mentioned in the .chm file.2) BMC_Open is the function call which connects the controller to the PC. By checking whether the call returned 0, one is effectively checking whether the connection was initialised successfully. I advise you to add an else statement which prints the returned value (the error code) in case there are any connection issues.3) Without a BMC_LoadSettings call, the PC does not know what motor parameters to use for conversions between real and device units. Every other method which requires such knowledge will be negatively affected. There are many other similar inter-functional dependencies (some functions need to be called before others in order for the code to run successfully) that are not documented. I agree that this situation needs to be amended.4) I will contact you directly in order to check whether you have identified a bug, or whether the custom limits get overridden by a different function call. If it is a bug, we will fix it by the next software release. In the meantime, you could bypass the problem by amending your code such that it checks whether a stage has been ordered to move outside of this custom travel range.

When using the Thorlabs device adapter library I can connect the controller through a virtual COM, however then the stage moves only along X axis and the delay between 2 moves is approx 10s. The other adapter Thorlabs APTstages appears unavailable in the Hardware configuration wizard of Micromanager despite I'm copying the APT.dll in Micromanager folder.The stage is working fine under Metamorph on the same computer.Can you confirm which adapter I need to use under Micromanager ?

Response from Ben at Thorlabs: I will contact you to see if I can assist you. Please note that Micromanager is an Open Source program and so it is possible that changes have been made to the program which is forcing this to not function correctly.

Response from Ben at Thorlabs: I am sorry to hear about your difficulties connecting our BBD202 controller to your computer. This question will likely require additional troubleshooting, so I will be in contact with you directly. However, one piece of advice I can give is that the "Firmware Update Utility" included with APT and Kinesis, is a good tool to use for initial communications troubleshooting. If your controller appears in the utility, that means that basic USB communications have been established with the controller.

Hi I have been using a range of APT software driven instruments such as TDC controller, BBD002 servo controller etc., I want to point out that there is some issue with 64 bit software for 64 bit platform. The 32 bit for 64 bit works fine. Secondly and more importantly we have been trying to shift to using USB/serial communication while I have been able to list the com port after enabling Load VCP in the advanced tab of the driver. However having hard time sending commans through serial terminal software such as commdebug, real term etc., They all recogonise the com port but the device is totally unresponsive left to wonder if there is some way to test the communication and if we need to use a FTDI library to issue a write command rather than through terminal software
msoulby  (posted 2015-09-28 10:14:12.0)
Response from Mike at Thorlabs: The VCP setting should be set up as follows. Baud rate = 115200; Flow control = RTS/CTS; Bits per word = 8; Number of stop bits = 1; Parity = NONE. We have contacted you directly with the latest version of the communications protocols for our motion control products and also some brief instructions on how to use this is a terminal emulator, in this case Termite. Using the identify command MGMSG_MOD_IDENTIFY (0x0223) is a good way to check you have established communication with the controller, this command will flash the front panel LEDs of the addressed controller.

I am using the BBD203 to drive a translation stage and we have encountered two issues:1. The controller seems to power off if left idle for over a few minutes, this is very inconvenient for remote controlled operation and I have not yet found a fix. I am using two controllers and only one of them has this issue. Can this setting be changed?2. The translation stage does not move in exactly 0.1um precision though the software claims it does. How exactly can this be calibrated?Thank you
msoulby  (posted 2014-07-29 06:24:12.0)
Response from Mike at Thorlabs: (1) The controller should not power off after just five minutes, I suspect that there could be an issue with that controller especially in light of the fact that your second controller seems to operate correctly. We will need to get the controller back for evaluation/repair. Our US office will be in contact with you shortly regarding this. (2) The brushless DC motors all make use of a linear encoder to give feedback from the stage to the controller to obtain the correct position, we are confident that the encoder gives the correct distance travelled. This closed loop system uses a PID control loop to control how the stage reaches the final position, these PID settings can be tuned in the settings panel of APT to suit different customer applications to account for load, acceleration, speed, move size, etc.. As you are using such a small move size it will be worth taking a look through the BBD203 manual for more details on the settings and how they affect stage movements, the manual can be viewed here http://www.thorlabs.de/thorcat/23900/BBD203-Manual.pdf

Hello again. Did you manage to find a workaround to access motor's serial number from the controller?We are considering making a comercial product based on your BBD controller and MLS motors. Obviously, we would like to protect our product from being purchased once, but used on many setups with the same controller (just by replugging cables). So a workaround will be very much appreciated!
msoulby  (posted 2014-07-03 10:28:15.0)
Response from Mike at Thorlabs: Unfortunately there is no work around for this. Our controllers can often operate with a number of stage variants which is why we have the APT config utility so that the user can assign each controller serial number to a certain stage or axis. This controller serial number is how each stage is identified in APT. This means that the controller is not limited to using just one type of stage. However this does mean that attention needs to be paid to how the cables are connected to ensure you assign the correct axis to that particular channel.
ilr  (posted 2014-01-22 02:42:11.16)
Thank you again for the explanation, Mike! Since HWSerialNum is a property from the MG17Motor control, I thought I was setting up a motor's S/N, but now I see what you mean. I would really appreciate any workaround.
ilr  (posted 2014-01-20 17:46:58.493)
Thank you for your reply, Mike! I am a bit confused now, even though I have programmed fully one setup. Does the motor serial number belong to the controller or to the translation stage (MLS203)? I am asking because I would like to programmatically bind a translation stage to a particular controller, so that one cannot plug another (but same model) stage to a given controller. I was thinking to use controller's S/N together with motor's S/N. Is that possible?
msoulby  (posted 2014-01-21 05:00:24.0)
Response from Mike at Thorlabs: There is a motor serial number and this is read by the BBD202 controller, however as this is not generally required we did not develop an ActiveX method to help expose this. The only serial numbers you can use will be the serial numbers of the controller channels and not the motor. As the APT server does not see the motor it only sees the controller then each serial number needs to be configured to a particular stage before run time in our APT config utility. The APT config utility sets parameters used by the APT server specific to the stage you are using, for example travel length, max velocity, max acceleration, etc… these settings are all stored in the APTServer.ini file in the windows directory. As the APT server does not see the motor it is not possible to set a controller to a specific motor; currently the only way would be to ensure the same channel and stage have their connectors clearly labelled. We are however looking to see if there might be a workaround to access this value from the controller and we will contact you directly with our findings.

I am using BBD202 controller and two motors with my own software to make 2D scans. To enumerate the motors and get their serial numbers, I use the technique described in the manual. In particular, I use MG17System object and its methods GetNumHWUnits and GetHWSerialNum. Those serial numbers are then used with MG17Motor to address the particular motor.Now I would like to buy one more BBD202 controller, which will be controlled simultaneously with the same software (my own). How do I distinguish between the two controllers? I know that they have different serial numbers, but I could not find any reference in the manual saying how I can obtain this serial number and then use with the MG17System object to talk to the proper controller.Is it possible to operate two BBD202 controllers simultaneously that are connected on the same USB bus?

Response from Mike at Thorlabs: Yes it is possible to use two controllers simultaneously on the same USB bus. The only way to address each individual channel is to use the HWSerialNum ActiveX property from the MG17Motor control. The correct serial number can be found above each channel on the rear panel of the BBD202 controller. Each controller will have the same hardware type but will have a unique set of serial numbers allowing each channel to be easily recognised; each channel will need its own instance of the MG17Motor.ocx control.
