Repetier cant find gcode

I had the latest version of Repetier installed but after frequent issues I downgraded back to the original version that came with the printer .72 with slic3r 0.9.2.

The first 10 prints went mostly trouble free but now 2 seconds after hitting the slice button (to start slic3r) I get an error message that the gcode file can't be found.

appdata/local/repetierhost/composition.gcode

I coped the log and all I got was

21:22.943 : ok


I've uninstalled the program and reinstalled the latest version, same issue.

Uninstalled and reinstalled .83 and .84, same problem.

All versions of the software won't print anything. What do I do?

I had a error like this before. It was usually an invalid setting like setting the layer thickness thicker then the nozzle size to something like that.
Be sure to have the bottom log section large enough to see everything and have "Errors" highlighted.
If its a slicer error it should tell you what happened.
If that't not it I would delete all the settings out of the user profile when you swap versions.
Its at "C:\users\profile\appdata\roaming\slic3r". Have to have show hidden files enables in windows.

Have you sliced the file before?
I am guessing when you go to g-code editor there is nothing there.
does it render correctly in object placement?

It often occur when your press kill slicing or slicing error.
so you can open click the File-Show work directory

you will not find the composition.gcode

Solutions
1. you can find a successful slicing name as composition.gcode and put it into the work directory.
2. because the Repetier Firmware Uninstall is not kill the Regedit file.
you can delete "Start-Regedit-HKEY_CURRENT_USER-software-repetier" first, then reinstall.
3. the build-in Slic3r Version is 0.9.9.53, your can update it into the Slic3r Version 0.9.10.56

@panxinlong7373 Thanks,, It was a combination of a bad windows registry and having nozzle diameter smaller than the layer height.

@CrazymonkeyCM2 The item had been sliced many times before to fine tune the print. After many issues with infill, sidewalls, and top layers not filling it was recomended that I just uninstall everything and reinstall the original software which didn't have these errors.

Been pulling my hair out for the last two days.

I did not have the printer pluged in while troubleshooting the previous issues.

My computer can no longer communicate with with the printer anymore. Clicking connect, it says connected, but nothing works. All commands just keep building the the waiting que.

None of the communication settings were changed during this process, but because the registry settings were deleted, I reinstalled the arduino software that came with the printer. Windows says the driver were sucessfully installed

Then went throught the troublesooting, communication checks (com and bitrate) and still the printer does not respond.

Under printer information / machine type, all it says is unknown when connected, but number of extriders it reads as 1, which is correct, all othe fields are blank.

Do you guys have any idea what is going on?

If the botton goes to green a physical connection (driver) is possible, but something prevents communication.
If you have a printrboard set "Reset on connect" to disabled or you will have to wait forever. Or your baud rate is wrong.

baudrate was set at default 57600, but didn't work. lowered it to 9600, stopping at eack step, still didnt work. reset it back to 57600 anyway.

hit the reset button on the mega board, still didn't work.

usb makes a good connection and sound when plugged in and removed. same when hitting mega board reset button

device manager says device is working properly. those com and baud settings match repetier.

updated mega driver and that did not fix it.

7 commands waiting in the que, nothing else works.

I see you think the baudrate of the device manager has any influence. Well that is completely wrong. It is completely ignored. What must match is the baudrate configured in your printer and the baudrate set in Repetier-Host. Typical values are 115200, 250000 and 230400 baud. Depending on the firmware it may be changed with the eeprom settings, so values in configuration.h of the firmware must not be the one currently valid.

It finally worked on 250000, and 256000 baud. Never would have guessed it would work on that high a rate.

thanks

It will only work on one of both - I guess 250000. The other one is near by so small commands may work but larger will cause a higher error rate.
