In the example above, the Printer Status dialog on the left is ready for printing. Notice that each item shows OK and the Print button is enabled. From here you would choose your Print Job Options and click Print to start the job. Before the printer starts printing your file, it will first:
- fill the Build Bed with powder
- print a Purge Block (if the print head is new)
- spread a layer to ensure the Build Bed surface is smooth
- service the print head
If there are not enough materials to complete the job, or the printer is not properly prepared, messages appear similar to the example on the right above. When any one of these messages appears, the Print button is disabled. The remainder of this chapter describes how to clear a message in the Printer Status dialog and start the build.
