Skipping Vector Cuts

[Ed Maloney]

I'm having a problem with parts of some vectors being skipped. I cleaned the encoder strip and lenses. Run after that was an improvement, run after that a little worse, about 20 of 350 didn't complete. Problem is mainly on the right size of the bed and random. I cleaned the encoder strip again and while waiting for the job to complete, I thought I would check with the oracle of laser knowledge.

I would say the problem isn't in the positioning system, but the tube itself. I don't know if tubes gradually lose power, or stop firing intermittantly or both when they are ging bad, but I think the problem is in the tube. Maybe check some connections?

1st suggestion - Call Epilog tech support. Could be the main logic board, or the power supply, or the tube, or...

You might search the forum on "Epilog tickle" to see if it adjusting the tickle setting would help. Not sure if a bad tickle setting would cause dropouts in a vector well into the run - often it shows up as a delayed first pulse. But it might be related to your problem. In any event something is causing the laser to stop lasing in the middle of a cut.
