- 
-  * resin amount: calculate the volume of your model in a 3D application. Then calculate this amount in liters: 
-  * Volume of 3D model (mm3) * ( 10 to the power of -6 ) 
-  * resin cost: €108,00 per liter 
-  * material multiplier: 30%: material cost *1,3 
-  * machine time multiplier: €0,55 per hour

 +=== Error loading file === 
 +After a long time without use, the printer gave the message 'Error loading file' on the LCD screen when trying to start a new print. In the logs we found errors saying that it couldn't copy a file from the 'staging' directory to the print data directory because a  file or folder could't be found. We tried out a few different things but the probable fix for it is to clear out the data from the previous print. The brain of the Ember is a Beaglebone Black, the 3D print engine is calles Smith. 
 + 
 +  * Turn on the printer and connect it to a mac with a usb cable 
 +  * Connect to it over ssh: <code>ssh root@192.168.7.2</code> 
 +  * Empty the staging folder: \\ <code> 
 +cd /var/smith/staging/print/ # Go to the print staging/print folder 
 +# If there are files present, delete them: 
 +rm * # The -* deletes all files in the current folder 
 +</code> 
 + 
 +  * Empty the print data folder: \\ <code> 
 +cd /var/smith/print_data/print/ # Go to the print data/print folder 
 +# If there is a folder present in the Print folder, delete it: 
 +rm -r name_of_the_folder/ # The -r deletes the folder and it's contents. 
 +</code> 
 + 
 +Useful command line codes for this job: 
 +  * <code>du -d1 -h -x . | sort -h</code> du stands for disk usage. -h use human readable sizes. '.' Analize the current directory. Then | pipes the data to sort to put the larger files or folders on the bottom. 
 +  * <code>tail name_off_file</code> Show the last section of a file 
 +  * Log files are here: /var/log/ 
 +  * <code>df -h</code> Command for 'disk free': show how much space is taken by certain folders and how much of the partitions is left. 
 + 
 + 
 +If this doesn't work, have a look at [[https://www.topbug.net/blog/2013/04/14/install-and-use-gnu-command-line-tools-in-mac-os-x/|this article]]. We were suggested to install the GNU command line tools. Not sure if they're useful or not.
  
  
 +=== Tray jamming ===
 +Resin tray moves back and forth rapidly on the separation slide motion. We lowered the separation slide velocity and played with some other settings but no luck. We increased the motor current for both motors but no luck with that also.
 +Still trying to sold this issue.
