Dog remembrance sign

When we have had a dog pass away, we've always listened to the old Tom T. Hall song, "Old Dogs, Children and Watermelon Wine" while we grieved. We recently lost Quincy, a wonderful greyhound with a sweet spirit. I took some lyrics from the song to make this sign. The sign is printed in two parts: the sign and the frame. The two parts snap together (after you remove any burrs from printing) and do not require glue to stay assembled. That way you can change frame or sign colors in the future by just reprinting the part you want to change. Just pop the old one out and the new one in. Print the two files lying on the back side as they are shown in the photo of the finished sign. You'll still print them as two separate files, not assembled.

To get the lettering to be a different color than the background, one-color printers will have to either a) manually be paused to change filament just before the letter printing starts or b) a pause can be inserted in the g-code to pause automatically (best approach). Apparently the pause function is not universal or consistent. Some machines use an M0 code, some an M30. The Ender-3 V3 Plus uses a "Pause" code. I have included a photo to show the code inserted at the correct spot, highlighted for you to see. The line that begins with a semi-colon is a comment. The command is the next line. When the Ender hits that code, printing pauses and the print head automatically retracts and moves to a side position.

Once you change the filament, go to the settings screen on the printer and select "Extrude" and let the old color feed out, followed by the new color. Remove the extruded material from the print head, select the home icon (upper-left corner of printer display), tap the "play" icon and then tap "Resume." Printing will restart exactly where it left off.

NOTE ON EDITING THE G-CODE FILE
The example of the G-code file will have a different Z axis position than you should use. I printed at 93% size to get the entire frame to print on my V3 Plus (rotated 45 degrees to fit). If you print at 93% AND USE NO SUPPORTS you'll insert the pause at Z9.6. If you use supports or rafts, that value will change. In your slicer software, you can find what the correct Z position by stepping through the printing animation to see where the lettering begins).
