Problem with pre-release 3.1.18 and Canon 250D SL3

Question

I understand that the Canon SL3 is not yet supported, but I saw a post in July about supporting the SL3 in pre-release version 3.1.18.  When I test the camera with that version,  it connects properly  but when I click the Frame and Focus button the camera LCD shows an error message and BYE locks up.  The message is "Error 70   An error prevented shooting.  Turn the camera off and on again or re-install the battery"  Turning the camera off and on has no effect.  I have to reinstall the battery to reset it.    Please advise if I am doing something wrong or if I can provide more information.

It is brand new camera and I have not used it very much yet, but I have not had the error happen except when using BYE to access it with the computer.   It happens when BYE accesses live view.  The Canon EOS Utility does not cause the error when it accesses live view.  Cannon customer support said that since the problem does not occur in EOS Utility or when I use the camera otherwise, that they consider it a problem with the software.   Are you aware of other SL3 owners who are using BYE without this problem ?

Oh yeah, I remember that thread.  Thank you for pointing it out.

From that previous thread, I was able to conclude that this issue it related to the 5x zoom rectangle property.  The only way to maybe fix this without having a 250D on hand for proper testing would be to disable/deactivate the 5x zoom capability in BYE for this model.  I will try to see if this can be done without risking breaking it for other models.  If I find I can quickly disable the 5x zoom for the 250D I will release a new RC next week with that change.  If I find it puts at risk other models I will have to put this on ice until I get a loaner 250D to test and fix first hand.

Regards,

Hi, 

I just finished uploading RC12 in the pre-release section.  I made a small change when initializing live view and I'm hoping this may make a difference.  5X zoom may or may not work from this model.

Try it and keep us posted please.

Regards,

Hi

Any update to the Canon SL3 problem ?  I assume you received my log files a couple weeks ago

Did you try RC12?

EDIT: I replied too soon,  I see from your previous communication that you did try RC12.

No need to login remotely, I know what the issue is but it would help having a camera connected to my dev environment for testing.  This can;t be done remotely.  I have another fix I can try but the code is unstable right due to other uncompleted changes in RC13 :(

It seems this problem was known before I bought a Canon EOS 200D Mark II (I think is also known as the 250D SL3). The camera connects fine to BackyardEOS 3.1.18 but as soon as I select "Frame and Focus" the shutter quickly opens and closes then displays "Err 70". Any developments on this problem?

Perhaps you can detail your setup at time that this Err 70 occurs - 250D attached to Lens or T-Ring+Scope, Camera Settings such as Focus Mode, BYE Settings such as Live View Max Sensitivity.

While Guylain has previously indicated that he believes he knows where the Issue lies, it may be that the above info helps...

If the 250D has a "Face Detection" version of AutoFocus, ensure that is NOT the mode selected.

The camera has a lens on it but focus and stabilizer are off (error still occurs without any lens). Everything that I can find to set to manual has been set to manual. Face tracking is not selected. Live view max sensitivity is not ticked. Might have to play around a bit more.

Take a look at this.

https://cpn.canon-europe.com/content/education/infobank/camera_settings/eos_error_codes_and_messages.do

Err 70

Description: A malfunction with the images has been detected.

Resolution: Turn the power off, then remove and re-install the battery. Then turn the power on again.

Thanks. I did find that page previously but didn't really help as the problem simply occurs again. Thankfully, I can still take photos but if I want to frame and focus then I'll have to do it on the cameras own live view rather than on BackyardEOS.

I have a 250D also and does not connect.  It gives me these kind of errors in the logfile.

 ERROR -    at StructureMap.Diagnostics.GraphLog.AssertFailures()
   at StructureMap.Container.construct(PluginGraph pluginGraph)

It also lists no drivers when it tries to connect. I have 3.1.18. The SL3 claims no drivers at the Canon website. Not needed.

EOS utility connects but I see no Liveview. Thanks. Attached is my logfile.

Please start a thread in the future, your issue is not related.

Your issue is an installation issue. Please re-install and the StructureMap error should disappear.

There is a known issue in 3.1.18 with live view and the 250D.  I've attempted to fix this last week and I should have a tentative fix in the next release 3.2.0.  I would be able to release 3.2.0 as a pre-release within 1 to 2 weeks.

Regards.

cevoner,

Your issue is different from the original poster.

Do you have ASCOM version 6.4 installed? If not, please install it. It appears that BYE is being forced to try to use ASCOM 5.5 which is very old.

Hi, I uninstalled & reinstalled 3.1.18 & now I get the same issue as others. When I hit live view err 70 freezes my camera. And Eos utility is normal. It connects now but is kinda useless.

I still get Error 70 with 3.2.0-RC1 when attempting to use "Frame and focus", "planetary", or "Drift Align."

 

Please send me that logfile.

Yes I also installed 3.2.0 and still give the error 70 when entering "frame and focus". I love the idea of using plate solving in backyard EOS though! Nice development.

You must be ripping your hair out with this one by now.

Well, I'm not bald yet, lol.

I made another change in 3.2.0.RC2.  From astroman133's previous post (and investigation) it looks like a decimal (comma vs period) parsing issue. I added more control over this is 3.2.0.RC2 and I'm hoping this will be it.

I'll try to release RC2 within a week or so.

Sweet! I'll keep an eye out. For now I've been using EOS utility to frame and focus with a Bahtinov mask but if can all be done in Backyard EOS, that would take one more piece of software out of the stack and simplify things a little. Plus I like the FWHM method of focusing, which can't be done in EOS utility of course.
