Ultimate Powerbox v2 - connectivity issues? #44150
Thanks for the tip. I'm using Kstars/Ekos on a headless mini PC/ Ubuntu 18.04. I read some of the posts on persistent port mapping, but thought that this was only for USB-to-serial converters. Would the same technique (/lib/udev/rules.d/) work for regular USB devices?

The powerbox uses serial to usb adapter.

FYI, just an update regarding my dew heater power issues. It turns out I had a bad dew heater on my guide scope. Moving the primary heater to the other ports on the UPBv2 showed amp draw at each port. Looks like mine is working perfectly, and I rooted out an issue with other equipment that I wasn't aware of.

Wow - thanks knro! Your help is much appreciated!

OK so I will go ahead and make a udev rule for it. Maybe I have a bunch of USB devices that should also have persistent mapping. :unsure:

How can I tell if a USB device is using a serial to usb adapter internally?

check dmesg, you'll often see it getting assigned /dev/ttyUSBX or /dev/ttyACMX. From lsbusb, you'll see it's using Prolific or a similar USB-serial chip.

I entered this line into the /lib/udev/rules.d/99-observatory.rules file as shown in the tutorial. There was no other identical device, so I skipped the serial number.
SUBSYSTEMS=="usb", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6015", MODE="0666", SYMLINK+="UPBv2"

So is it legal use the device symlink /dev/UPBv2 in the Indi driver port field?

An update on my experience using this box. Earlier I thought I had issues with my dew heaters since they were not always reporting AMP draw. Initially I thought this was due to one of my dew heaters being bad. It turns out, if you plug it in, and hold it in your hand, then turn it on in the Powerbox, it heats up despite that it says there's no amp draw. After talking with Pegasus, it turns out that this is due to the size of the dew heater strips. It seems anything shorter than 3" draws such minimal amps that they have trouble reporting it correctly in the Powerbox, so they just report 0 amp draw instead. Longer dew heaters show proper amp draw.

Second thing. I've been using the Moonlite focuser cable connected to my Moonlite stepper motor. I'm not entirely sure it's working properly. The first few nights, all my images were out of focus enough that I couldn't really use the images, yet whenever the focuser would run, it would show it barely moving and quickly achieve focus. I think this was initially because I hadn't set back focus. I've never had to do this with the Moonlite using it's own focus controller. I'm thinking the Moonlite focus controller must have some sort of built in backlash compensation, because movement is perfect. I'm currently processing a set of images from last night that used the UPBv2 with backlash compensation set (I set it to 25 steps after watching closely for slight movement). Performance in focusing within Ekos seemed about the same. I didn't see lots of variation in the focusing, and it came to focus really quickly, which leads me to believe it didn't quite work. Like the focus changes were actually just seeing, and not movement from the focus motor.

When I issue a command to move a few steps, I don't really see any movement, and the gear box makes a slight electric sound (that I've not heard before). I'm wondering if voltage is correct to the focuser? It should be, but I don't know how to control that. It's not until I issue a command of moving 1000 steps that the movement seems obvious. So, thinking there might be a slight issue here. I'll report back after I have processed the images from last night.

Ultimate Powerbox v2 - connectivity issues? #44330
I too have experienced issues with Moonlite focus stepper and UPBv2. I spoke with Pegasus Astro about this and was told that the Moonlite stepper is what they used for testing. I have found that reducing the speed to 50% in the indi control panel has helped yet I'm still not convinced it's working as well as the Moonlite controller.

I did manage to borrow a windows computer (I do not own one) and test the Pegasus Astro control software with the moonlite focuser and the stepper appeared to operate normally.

Waiting to receive the unit back for further testing.

I have shipped the unit back due to the variable output not working and I'm waiting to get it back to actually use the device for imaging.

I am using ZWO ASi 1600mm-pro and ASI 120mm-s cameras and I've also experienced connectivity issues using the built-in USB hub. Is anyone else experiencing these issues?

I’ve not experienced any intermittent issues with the USB, so far that part has worked well for me.

There are a bunch of settings for the focuser that I’m not entirely sure what they do. They’re all set to 0. I’m sure some of these settings might need to be tweaked. There’s nothing in the manual that explains these settings. So I plan on asking Pegasus what they do.

Hmmm why would that be the case? Does the Windows Pegasus astro version have any more functionality than the INDI driver? Is there any log from the Windows software? perhaps we can compare the set max speed (SS) and move Stepper to new position (SM) to what the INDI driver sends.

EDIT: I communicated with Pegasus Astro and the maximum speed should be set to less than 1000. I saw in one the previous logs a speed of 65535 which is set by the firmware when the speed is invalid. So check the maximum speed and set it to a reasonable value for your focuser and then check its

I heard from Evans at Pegasus Astro, and here's what he said.

Hi Andrew,
Something is going wrong in the max motor speed or backlash values you had setup. Voltage is fine and please note that this motor controller development was made by using a robofocus and a moonlite motor.
I strongly advise to use 400-500 max motor speed and remove backlash values.
I can assure you that the controller works absolutely fine with the Moonlite Motor, even at very low steps.
I got some questions from Jasem so I think the problem is still on the max motor speed. If the max motor speed is wrong the motor coils are not energised correctly and you loose step.
Regards,
Evans


I'll be adjusting my max motor speed to reflect this since it was not the default setting. Hopefully that will make it work properly.
