Getting started with the K40
« on: November 10, 2017, 01:29:46 PM »
I am going to make a series of small posts each covering one item rather than one large one with everything so we can talk about each item separately. The very first thing in looking at the wiring.

Before using a new K40 you should do a full review of the wiring. Make sure that all of the connection are made well. Some machines when delivered some of the wires are ready to fall off. I had a power connector between the power supply and the controller that was not well crimped and a small pull and the wire came out. Make sure the machine is well grounded. Fix or replace any connections that are questionable.

You should do this before you ever plug the machine in because the power to the laser can be as much as 20,000 volts. After the power has been turned on the capacitors can stay at these high voltages for a long while.  So when looking at the wiring keep in mind that you life could depend on having good solid and insulated connections on all the wires.
