Tiko
I was fortunate enough to receive my Tiko for Christmas from batch #1. Starting on Christmas day I printed a bunch of owls, a benchy, and some other ornaments as well as the Tiko demo print.
Things I've designed
-
- Top hat (for a failed owl print)
- Camera mount - in progress
Linux Shortcuts
Switch to Tiko network:
alias tiko='nmcli c up "Tiko"'
Run
alias tiko='nmcli c show'
first to identify your connection name

Temperature readings
Maximum temperature2) : 300°C
Method
A Type-K thermocouple was attached to the side of the heater and wrapped with several turns of Teflon plumbers tape to attach the thermocouple without risking melted tape or adhesive on the hotend.
One consideration of using an IR thermometer is that the thermal emissivity of titanium will cause the IR thermometer to read low. Though this may not be a problem with plastic stuck on the nozzle or by taking the reading from the ceramic heater.
Observations
Red LED is connected to the heater PWM. Solid red when it's coming up to temperature, flickering when it's holding temperature.
