You'll Shoot Your Eye Out
This is a simple tip. I hadn't used a MakerBot heated build platform with the wiper until recently when I got a Thing-O-Matic and I was annoyed at how the pre-wipe commands sometimes don't actually wipe off the extrusion. This is because the path depends on where the object starts. So like most people it seems, I turned the wiper so that it was diagonal to increase the chance that the tip moves across the wiper. A better solution is to mount the wiper horizontally and add this gcode command to the end of your start.gcode so that it always moves slowly across the wiper blade:
G1 X52 Y-37.0 Z10 F300.0 (move across wiper)
The down side is that my ToM now seems determined to violate the first law of robotics by flinging the plastic noodle into my eye as I lean down and stare into it!
