I can connect, and control my printer fine,

I can connect, and control my printer fine, but when I try to print from sd card (what I really need it to do!) I get a message saying it failed…
This is on a Makergear M2 running Marlin firmware on a RAMBO board.

I should add that I’m generating my Gcode with Simplify 3d creator software

I guess you mean the SD card in the printer (not in the tablet). What exactly fails 1) uploading a gcode from GCodePrintr to the SD card 2) choosing a file from the sd card and start print ?
Please enable debug logging and send me the console output (long press on console -> send email) Thanks !

Yep, it’s the sd card in the printer, and choosing a file from the sd and starting a print. I’ll get you that log. Great response time!

Here’s the log link: https://www.dropbox.com/s/9azv7rf3hm5jny0/gcodesimlog.txt

Ok, I can see the error but I’m not yet sure why it can’t find the file.

Which GCodePrintr Version do you use ? Did you try the beta v1.64 already ?

I haven’t tried it. Is it available from your website? I have the current play store version.

See here how to participate in the beta test:

Ok, tried it with the beta version, but I’m still getting the same error. I have a second M2 printer setup to use a VIKI lcd (with different firmware) so I’ll give it a try and see if the firmware makes a difference.

Thanks. I will do some tests tonight and see if I can find a bug.

I just published v1.65 beta with a fix. There was a parsing problem when using folders on the sd card. Please retry with the new beta. (might take some hours until it is available)

Awesome thanks! I’ll give it a go.

Latest beta is working good on my M2. Great job!
