Speed Adjust UI
A. Current speed
B. Selected speed
C. Print time estimate (for the selected speed)
D. Interpolated/extrapolated parameters: acceleration magnitude (M204.2), feed rate (M220), and time remaining (M73.2)
E. Toggle step size of the dial (2 or 10%)
F. Apply the selected speed
G. Return to the OEM speed adjust UI
X1Plus adds a custom UI element that provides greater control over print speed than the OEM UI offers. A dial with an adjustable step size allows users to apply any speed multiplier from 30 to 166%. Additionally, the UI calculates the estimated print time remaining for the selected speed, allowing users to see in real time how these adjustments affect uptime.
By default, the OEM speed adjustment UI is displayed to all X1Plus users, and this customized UI can be enabled via two methods:
- Open the speed adjustment menu and press the ">" icon in the corner of the window.
- Using the X1Plus CLI, set the following setting:
x1plus settings set printerui.speedadjust true
X1Plus will remember this choice until you press the "<" icon on the X1Plus speed adjust UI or modify the setting.
The step size of the dial can be adjusted by toggling the 'Step size' button in the window or by modifying the following setting with the X1Plus settings CLI:
x1plus settings set printerui.speedadjust.stepSize 2
Print speed adjustment on X1, P1, and A1 Bambu printers is applied with a series of 4 different Gcode commmands:
Acceleration magnitude. K is a unitless multiplier of acceleration
Feed rate. K is a unitless multiplier of feed rate
Time remaining. The percentage speed is calculated from the inverse of R x 100.
Tells the UI which string to display ("Silent", "Normal", "Sport", or "Ludicrous"). It can be ommitted
Below are the parameters for each of Bambu's speed profiles obtained from log data. X1Plus uses cubic spline interpolation and linear extrapolation to calculate acceleration magnitude and feed rate, which it then publishes to the printer when the 'Apply' button is pressed.
| Speed (%) | time_remaining | accel. magnitude | feed rate | |
|---|---|---|---|---|
| Silent | 50 | 2 | 0.3 | 0.7 |
| Normal | 100 | 1 | 1 | 1 |
| Sport | 124 | 0.8 | 1.4 | 1.4 |
| Luda | 166 | 0.6 | 1.6 | 2 |
