PIDKiln v1.2 update

I’ve just created v1.1 release of PIDKiln, and bumped development version to v1.2.

Most significant change in release 1.1 are:

  • replaced MAX31855 library with another one – it’s much cleaner and easier to modify
  • much better MAX31855 error handling, both with thermocouple and MAX31855 itself
  • introduced network logging with syslog protocol – so you can watch all debug information on remote host
  • all logging settings are now in Preferences
  • compressed local JS, and created separate Preference setting to allow remote downloading of JS scripts (Internet connection required – recommended to use)

And I have also (after some 1.2 changes) first, real Kiln test run.

With two termocouples and power meters.

Engraving, cutting 5.5W laser – description and proper connection

During upgrading my engraving machine (Chinese so called CNC 3018) I had to do some reverse engineering to do proper connection.  Perhaps someone else may find this information useful – so here you go 🙂

Laser itself is distributed as two part set. Laser in aluminium cooling block with fan (and four wires), and PWM/TTL controller board.

Controller board uses this main components:

  • XL4003E1 – voltage regulator with input voltage 5V-32V, 4A CC max with 300kHz switching frequency
  • IC chip MCP60021 OPAMP – operational amplifier
  • Voltage regulator 78L05 – 5V output, 100mA
  • NPN transistor D476 61C
