Printrun-Mac-03Feb2015.zip - odd exception when printing #619

mhackney · 2015-02-05T14:52:19Z

I just installed the new Printrun-Mac-03Feb2015.zip on OS X 10.10.2 (Yosemite) this morning. Everything configured fine. I am commenting to a smoothieboard over tcp to a 3D printer. When I load the gcode file, all looks good. Then when I run, I get this in the console:

Print started at: 09:44:22

The object starts printing and then I get more errors thrown to console:

It is printing all through the above. It seems odd that there would be a path to /Users/craigvanvliet - my user name is mhackney on my mac, Craig must be a developer?

mhackney · 2015-02-05T14:59:53Z

Just an update. The printer/Pronterface lock up and must be reset. This happened on 3 prints somewhere around the 3rd to 4th layers. I have not been able to complete a print. When this happened, there were no errors in the console (they were long after the string of errors I attached above and I cleared console so I could look for new errors - there were none, just the lock up).

kliment · 2015-02-05T15:03:08Z

It's the username of someone who kindly donated a mac for these builds - pyinstaller embeds the full path into the file.

The timeout is likely due to network errors - might need to adjust the timeout value there, the tcp printing is not particularly extensively tested. Strange that the print didn't stop after the "disconnected" message, by all measures it should have. I'm not entirely sure what's going on here.

The other error is means we don't have a means of inhibiting power management. It's probably a namespace issue due to the way pyobjc does dynamic import. I'll see if I can do anything about it.

mhackney · 2015-02-05T15:11:11Z

Thanks for the update. I don't think I can change the timeout without compiling the code can I?

I have the smoothie direct to a 5 port gigabit ethernet switch. My mac host is on another port. the switch direct connects to my cable modem. All traffic should be from my mac to the printer. the smoothie port does show an amber light meaning it is not a gigabit connection.

mhackney · 2015-02-13T20:22:44Z

An update klimant, the print actually does stop after the disconnect, its just that there is gcode buffered at the other end so it takes some time before the print stops, but it does.

I am still experiencing this problem 100% of the time. I tested on 2 different networks with completely different cables, etc. I've monitored the network and see no issues with latency. I have a similar issue with timeouts when using the Python upload script that's now part of the Smoothieboard project. I had to increase the timeout to 20sec. I've had lots of issues with my Smoothieboard so it very well could be a hardware issue with it. I am getting another board soon so I can test when that comes in.

sunomie · 2015-02-20T05:37:05Z

I can confirm also seeing '[ERROR] Failed to set power settings' when attempting to print from OSX.

fearfulWizard · 2015-02-20T08:01:09Z

I am also having the same issue.. Does it have to do with the build?

Does the actual print work or does it stop after that error?

For me, after I get the [ERROR] Failed to set power settings: message, the print starts but then fails shortly with a Not Connected message. This is 100% reproducible and I have not been able to use this version to print.

iXce · 2015-02-20T13:51:40Z

It's most likely unrelated to the error message, which is solely related to some power settings helper and not to the rest of the print stack. Now we need to trace these disconnections :/

fearfulWizard · 2015-02-20T19:53:04Z

The printer does not work after that error. I must mention though, I do not have the extruder yet on my printer, so I tried simply running it by having it draw a 2D image with a pencil. This is my first printer, so i might've missed the "power settings", but I'm not sure what this is referring to: the configuration of the firmware, or power settings of the Gcode.

iXce · 2015-02-20T20:05:26Z

It actually refers to power settings of the host operating system, that is to make Printrun run as high priority and inhibit sleep. So it shouldn't affect the print itself.

sunomie · 2015-02-22T01:04:04Z

Does not start printing for me on OSX. Ended up switching to my Ubuntu box
and compiling then printing.

I think I've managed to solve this temporarily by switching to a previous build. Please do let me know how I can fix the issue if it's mainly a namespace error. Thanks

mhackney · 2015-02-24T02:13:53Z

Another update - the Windows version running in a Win 7 VM on the same mac is working fine, no network time outs. And of course it does not generate that initial "Failed to set power settings"

craig donated the mac computer that I use to make the mac builds. I'll
take that path out of the build script for the next one to avoid confusion

I printed the the android test little guy with minor issues (printer was not calibrated yet) but i downloaded the kendal90 slic3r configuration that I got from here.

http://wiki.imal.org/howto/how-print-mendel-90

opened up a part I was going to try and print exported gcode and I got that in pronterface.

b4stien · 2015-05-06T09:51:06Z

Exact same problem here, with a gcod file as well.

mjbouchery · 2015-05-11T22:08:53Z

I wonder what is going on. It is weird. It printed the android guy just fine. but with the other gcode I am having an issue.

JohnWasser · 2015-05-14T14:56:10Z

Looks to me like in printrun/power/osx.py lines 40 and 41 should be changed from:

    encoding = CoreFoundation.kCFStringEncodingASCII
    cfstring = CoreFoundation.CFStringCreateWithCString(None, string, encoding);

to:

    // encoding = CoreFoundation.kCFStringEncodingASCII
    cfstring = CoreFoundation.CFStringCreateWithCString(None, string, kCFStringEncodingASCII)

iXce · 2015-05-14T15:15:49Z

Hmm, but kCFStringEncodingASCII does not exist in this context, does it ?

JohnWasser · 2015-05-14T17:19:08Z

iXce, I expect it is a constant defined when you import CoreFoundation.

iXce · 2015-05-14T17:24:23Z

That's not how things work in Python I think, if nothing explicitly imports the symbol it cannot be there (you'd need something like from blah import * for something like this to work)

kliment · 2015-05-14T17:28:26Z

None of the CoreFoundation stuff makes any sense to me honestly, so I'm
willing to try it out.

iXce · 2015-05-14T17:35:46Z

Let's debug this properly: could you pop a python shell, do "import CoreFoundation" and then "print dir(CoreFoundation)" ? Thanks !

Typing CoreFoundation.kCFStringEncodingASCII into the python shell displays 1536 (= 0x600 which is how it is defined in CFString.h)

iXce · 2015-05-14T18:14:56Z

Okai so it's definitely in the system CoreFoundation module. Now the question is, why isn't it in the binary ? Is a different CoreFoundation module shipped with the binary ?
I pushed a dirty workaround for now

kliment · 2015-05-14T18:16:07Z

It's in there but when corefoundation is packed into a binary everything
gets renamed in some weird way

Hey Markwbrown, I'm only a very begging user with 3D printing, and I like Printrun, but this is a killer problem, I'm not a programer so I can't help solve it, but if I can run tests for the Programing Gurus, I'm more than willing.

Hi Kliment,

I just installed the 2.0.0rc5 (pronterface) and have the same issue. The error message has changed to read

I also notice that once this error was issued the printer needed to be power cycled to get any response. I am using Marlin Version 1. on ramps 1.4.

The exception was: ValueError: Expecting byte string of length 1, got a 'str' Yet bytes with any length appears to work, so i assume it is bogus. Fixes kliment#619 (comment)
