Panogy, this is the correct path. But try the 2.1.15 release. As Andrew said, the plugin in now included. Wow, Thank you, Frederic you always exceed my expectations... Yes sure, I did install the latest version now ;-) But how do I replace the plugin if I need to change anything? For some reason th...

And here we are, in that case I'm sure the Merlin compensates the backlash internally, as I expect such a low cost gear has at least 1.5° backlash. I don't have a Merlin, but maybe one can confirm how far can you turn the head manually, before the encoder starts to rotate. You have to do this test ...

And no, I don't manage the backlash. Be aware that it is not that simple, and mainly depends on the load. For example, on the pitch axis, you don't know if the load will put the backlash on the up direction, or on the down direction, depending how the camera/lens is balanced... The wind can also be...

I have an additional question related to the gear backlash.
Do you take care of it or is the slave responsible to compensate the backlash when the motor direction is toggled?

I have seen there is a parameter in the plugin,
AXIS_ACCURACY = 0.1 # °
what is this good for?

I understand what is the timeout problem: when I request a position from the core, I send both axis positions, and the position is first sent to the yaw axis, then to the pitch axis. And while you start the first, the second can't be executed, and the timeout occurs... In Merlin, there are 2 proces...

I can't do that without (big) modifications to refresh the GUI while you send progress... Think that you will also have to take care of all timings (stab. delay, shooting time). And it can take a lot of memory to store all commands. Yes I agree, the communication like it is today is fine, each sing...

I already repeat the command if the timeout occurs; I do that 3 times, Would it be possible to repeat the command let's say 10 times? or have a parameter how often it should be repeated? But what I don't understand is why you don't first acknowledge the command before starting to execute it? But al...

Yes you are right the position is not refreshed during this second because my controller is busy and can't answer the request. Since I add the delay it works fine even the position is not refreshed during that time. Anyway it is not needed to know the position every single degree. As I mentioned ear...

Hi Frederic I have implemented the following workaround for now by changing the plugin: 1. after sending the goto position, sleep for 1 sec. Anyway the head needs some time to drive to the new position 2. and I have removed the J command it is not a very elegant solution but at least it works. Do yo...

Hi, till now I did not implement the start moving function only the goto. I started to test the movement with a preset template 6x2 pictures and the head moves both axis to the right positions. In the GUI it shows the dots as red and not as green, and in the log file the error I posted. As I'm in th...

Hey Frederic, this is unbelievable, you made it in this short time frame! Thank you very much! I got the plugin installed and it works so far. The connection is established and the head is moving to the right positions, only the J command is not in synch. IOError: Timeout while reading on serial bus...

I agree, but I also shoot some gigapixel panoramas using autofocus ...
And this would not have been possible with manual AF, except you stop the head after each image and refocus manually.

Yes I know, but there are occasions where this works fine and I use 2 opto couplers anyway to trigger the camera.

In the status command, could you return 1 as long as the head moves? I mean, when I request stop to the Merlin, its stops motors, but because of inertia, it continues to move: I have to poll the position. So, after a stop (itself after a start moving), you should return immediatly to acknowledge th...

Status return would be one character, 0 or 1, 0=Ready, 1=Busy
Or do you think we need more?
