Configuring 0.99 3D Printing Extensions
<<< Back to Configuring Version 0.99 Main Page
!!!! TAKE NOTE: The 3D printer extensions documented on this page are pre-release and experimental (hence the leading underscore). These settings will NOT be present in the release ultimate 3D printing releases. Please expect any UIs or code written to these specifications to require changes. The settings on this page will be removed and will not be backwards compatible. !!!!
There are 3 heater groups. The examples below show heater group 1 - {_he1:n}
Setting | Description | Notes |
---|---|---|
{_he1:{e:...}} | Heater Enable | 0=off, 1=on |
{_he1:{p:...}} | Heater P (PID) | read/write |
{_he1:{i:...}} | Heater I (PID) | read/write |
{_he1:{d:...}} | Heater D (PID) | read/write |
{_he1:{st:...}} | Setpoint temperature | write-only |
{_he1:{t:...}} | Current temperature | read-only |
{_he1:{at:...}} | "At temperature" flag | read-only |
{_he1:{op:...}} | PWM output level | read-only |
{_he1:{tr:...}} | Thermistor resistance | read-only |
{_he1:{an:...}} | Heater ADC reading | read-only |
{_he1:{fp:...}} | Fan power | read/write |
{_he1:{fm:...}} | Fan minimum power | read/write |
{_he1:{fl:...}} | Fan low temperature | read/write |
{_he1:{fh:...}} | Fan high temperature | read/write |
PID settings for heater feedback loop. Typical default values are:
For an extruder heater, 12volt:
DEFAULT_P 7.0
DEFAULT_I 0.05
DEFAULT_D 150.0
For a heated bed:
DEFAULT_P 9.0
DEFAULT_I 0.12
DEFAULT_D 400.0
There are 3 PID groups. The examples below show PID group 1 - {_pid1:n}
Setting | Description | Notes |
---|---|---|
{_pid1:{p:...}} | Raw P Value | read-only |
{_pid1:{i:...}} | Raw I Value | read-only |
{_pid1:{d:...}} | Raw D Value | read-only |
These are Read-Only values from the live PID. They are not scaled to temperature
Setting | Description | Notes |
---|---|---|
{tram:t | Tram Command | Set and enable tramming matrix |
Setting Tram will use the last three Probe values to define the plane of the Z axis. For operation, probe the bed (Z axis) at three disparate points, then invoke Tram.
