Additional Settings

The Additional Settings tab of Device Settings controls the settings used in Preview for simulating a preview and estimating time. Changing these settings will not change anything about how the job actually runs, but can make time estimates more accurate.

The Additional Settings tab of Device Settings

Read From Controller

Use the Read From Controller button to sync these settings with your laser's internal settings, providing much more accurate time estimates without manual adjustment.

Manual Adjustment

Note

Y Axis Speed and Acceleration values are often set lower than X. Due to the greater mass of the Y Axis gantry, many lasers must travel slower in the Y dimension to avoid slipping.

Setting Description
Maximum Speed X/Y The maximum speed at which the laser can travel on the X and Y axes, individually.
Cut Acceleration X/Y The maximum rate at which the laser can speed up or slow down during Line operations.
Engrave Acceleration X/Y The maximum rate at which the laser can speed up or slow down during Fill operations.
Corner Accuracy A value used to estimate cornering speed. Corner Accuracy is not read from the controller. Read more about how this value works for lasers with GRBL controllers here.
Minimum Corner Speed The slowest possible speed the laser will turn corners at.
Cut Speed Scale Scales cut speed estimates by this percentage when simulating job times. Not read from controller. Use this value to manually fine-tune estimates.
Global Speed Scale Scales all estimates by this percentage when simulating job times. Not read from controller. Use this value to manually fine-tune estimates.

Troubleshooting

  • If you aren't seeing a setting you expect to see, check which tab you're in and make sure it's applicable to your laser.
