Homing under Open PnP Software and Camera config.

[Hartmut Eger]

I need your help again.
I have all steppers and end stops in operation.
My config file is set with all values and the G28 command is sent via Pronterface and all axes move to the desired parking position. (Thank you Mark)
Now I would like to make this setting in the Open PnP software too, but I haven't found out how yet. It seems to me that the config of my smoothie board is not adopted.

Can someone help me with that.

2nd problem are my two cameras
I set up my up camera and it works fine.
My down camera just doesn't want to be set up in the Open PnP software. I tested the cameras under Windows 10 and both work perfectly. My cameras and the Smoothieboard are connected to a USB hub (without power supply) and this hub to my computer.

Can somebody help me with it

Thank you very much and greetings
Hartmut

RE the cameras, I have a similar issue.

I have 2 usb cameras on a single pc USB port via a hub. using the Microsoft Camera app in Win10 and Win11 I am able to toggle between the cameras and they work fine. Unfortunately the Camera app will only show one camera feed at a time and Win wont run another iteration of the camera app to see the cameras run side by side. In Openpnp both cameras are visible and can be set, but only one cameras feed is visible within Openpnp. The above is when using 2 cameras using 1 USB port via a hub. At first I thought this was a power issue an bought another hub that is powered and is 'sync able'. Still this arrangement doesn't work in Openpnp.

Otherwise if I use 2 pc USB ports for the 2 cameras everything works fine within Openpnp. I have 3pc USB ports so this isn't a functional issue, but it would be nice to not have to break out an additional USB line to the pc.

If you guys are talking about the ELP Full HD camera it is a know issue. The bandwidth of USB 2.0 is simply not enough for two. You need two USB root hubs on your computer.

Note that adding a USB 3.x hub does not help, it does not repackage packets or something, it simply routes the USB 2.0 through as-is.

The issue is linked in the FAQ:

Hello Mark,

I have now connected the cameras individually to my PC via BSB and both are working.
Many Thanks.

I can show you my status from Issues and Solutions, but I can't really figure it out.
