Klipper Q&A

On this page, I will attempt to cover all things Klipper giving you the tips and tricks I’ve found setting it up on multiple printers and helping people get their printers configured. This is a living document that will be updated as needed.

Where can I find all the answers?

In the Klipper Documentation

How can I wait for the chamber to heat up before starting my print?

Add an enclosure thermistor and set it up. My setup looks like this:

[temperature_sensor enclosure_sensor]
sensor_type: NTC 100K beta 3950
sensor_pin: PF5
min_temp: 10
max_temp: 100

Add the following in your PRINT_START:

#Turn on the bed heater
M190 S{params.BED}
#Wait for the chamber to get hot
TEMPERATURE_WAIT SENSOR=“temperature_sensor enclosure_sensor” MINIMUM={params.CHAMBER|default(0)}

Then, make sure you Superslier Start G-Code includes the following:

CHAMBER=[chamber_temperature]

You can use your hot-end thermistor to wait for the chamber to come up to temperature. To do this, replace the TEMPERATURE_WAIT_SENSOR line above with:

TEMPERATURE_WAIT SENSOR=extruder MINIMUM={params.CHAMBER|default(0)}

Note:

To make this all work, you need to set your timeout to something higher than default.

How can I make Klipper wait to heat-soak the chamber?

Add a dwell command after you start the bed heater:

# Command is G4 P<milliseconds>, so the command below waits for 10 minutes
G4 P600000

Can I make my cabinet fan run at a different speed?

Add the following to your [controller_fan] section:
max_power: .5 # max is 1, minimum is 0
