Hi all,

Just installed pronterface using the latest versions and keep getting errors. I deleted and reinstalled it several times with no changes. I know the printer itself is fine because it was working before at the guys house who rebuild it. I was using an Azteeg X1 but when that died the original builder installed a smoothie board and was using pronterface. It was printing fine when it left his place.

The errors I keep getting are:
Printer is now online.
[ERROR] Traceback (most recent call last):
File "printrun\printcore.pyc", line 241, in _readline
File "printrun\pronterface.pyc", line 1713, in recvcb
File "printrun\pronterface.pyc", line 1669, in update_pos
ValueError: could not convert string to float:

Board: smoothie
Pronterface version: printrun 2014.08.01

I am able to turn on and off the extruder but that is it...

another note: when I look at the files in the printrun folder, I donot see any that end in .pyc, mine all end in .py (example printcore.py, instead of printcore.pyc)
I am not ever sure where to begin looking... any help is greatly appreciated.

.pyc is just the .py files already compiled into a more executable format

You change the .py, the pyc get updated next time your run it.

See [stackoverflow.com] for more details.

That's a very old version of pronterface... latest from github is 2015.03.10

Try the binary from [koti.kapsi.fi] not the latest, but better than what ever you found.

Hi Dust and thanks for the help!

The files I downloaded is the same files you recommended: Printrun-Win-Slic3r-03Feb2015.zip from [koti.kapsi.fi]

If you go to the help menu / about printrun is says version 2014.08.01 in it.

Also thanks for the link which explained .py and .pyc

problem resolved,

Had to reinstall the firmware and now its working
