Laser Status Update.

LCC has located an issue with the Laser Power Supply. We need to do some rewiring.

New limit switches for laser door arrive tomorrow.

Hope to have laser cutter back online late Weds or Thurs.

Laser cutter is back online and working now.

Two issues:

  1. The silicon tubing insulating the high voltage wire between the power supply and laser tube (8+ years of aging) broke down. This allowed some electrical arcing between the laser tube wire and the power supply case.
  2. The laser door interlock switches were flakey.

Shoutout to @johnc troubleshooting Monday and for todays fixes which include.

  • wired in the new high voltage connector between power supply and laser tube
  • rewired eStop to kill power to power supply which now Stops tube from firing and motors from moving, much improving safety to users.
  • installed new door limit switches and rewired to controller.

New High Voltage Connector between power supply and laser tube wired in (White connector at back). Thank you to @rsim for ordering this for VHS.

New wiring for eStop

New interlock switches installed. Thank you @Janet for ordering and donating new ones to VHS!

These interlock switches were flakey and end of life.
