Correct me if I'm wrong, but it looks as though a copy-and-paste operation went awry in the following code (check out the delay specified in the last line):
def penDown( self ): self.virtualPenIsUp = False # Virtual pen keeps track of state for resuming plotting. if (self.bPenIsUp != False): # Continue only if pen state is up (or unknown) if ( not self.resumeMode ) and (not self.bStopped): # skip if we're resuming or stopped self.bPenIsUp = False if self.penDownActivatesEngraver: self.engraverOn() # will check self.enableEngraver ebb_motion.sendPenDown(self.serialPort, self.options.penUpDelay )
