decrypt 3w
"Past release of XYZware used to generate *.3W file which is actually just a base64 encoded gcode file. However, recent XYZware hardened the format by AES-encrypting ZIP-ed gcode, instead of just encoding in base64." https://github.com/tai/decrypt-xyz3w issue: https://github.com/tai/decrypt-xyz3w/issues/1
Printing to directly to davinci

calculate checksum:
[[http://www.soliforum.com/topic/6279/xyzprinting-da-vinci-10-hacking/page/4/|DanNsk says]]: BTW - just realized checksum is just a sum (only gcode part, after replacing '
' => '
')
that gives 4 bytes - 00 00 b9 2e for minimal.gcode exact as hardcoded in print-to-davinci.py
public static int checksum(byte[] arr, int start, int len) {
int num = 0;
for (int index = start; index < start + len; ++index)
num = (int)arr[index] + num;
return num;
}
