Troubleshooting - Output Issues

Output is mirrored or backwards

  • The 'Device Origin' setting, found in the menus under Edit => Device Settings, controls the orientation of what gets sent to your laser. If you have the origin for the device set incorrectly, your output will be mirrored or upside down when run.
  • For DSP controllers (Ruida / Trocen / TopWisdom / etc) the Origin setting for the device should match the corner that your laser homes to when first powered.
  • For GCode controllers (GRBL, Smoothieware, etc) the Origin is almost always front-left, but in rare cases may not be.

Output is shaky or wobbly

Output is slanted or skewed

Edges of engravings are burnt or too dark

On GCode devices, enable 'Overscanning' in your Fill or Image layer setting. If you already have this enabled, you might need a larger value for the overscan setting, particularly if your acceleration is low.

Edges of engravings are fuzzy or blurry

First, make sure that your X-axis drive belt is tensioned correctly. If it is loose, you'll see blurred or fuzzy sides when engraving, as well as 'bent' or inaccurate shapes when cutting. If the belt is properly tensioned, you likely need to add scanning offsets.

Corners are not cutting or marking

When using a DSP controller, the Min Power setting is also sometimes referred to as 'Corner Power', because it sets the power level of the laser when the machine is moving slowly, like when cutting a sharp corner. if your Min Power value is too low, when the laser slows for corners the power value might fall below the firing threshold of your laser. This will leave gaps in the output at the corners, and at the points where cuts start and stop. Increase the Min Power value.

Corners are burnt or too dark

Similar to the above, if the Min Power setting is too high, the power value may not be reduced enough when the laser slows for corners, and can leave burn marks at corner points or the start / stop points of the design. If this is happening, reduce the Min Power setting.

Laser is losing power / not cutting at low speeds

On DSP controllers, If you are running a cut at very low speed, set your Min Power and Max Power values to match.

There is a setting in the Machine Settings, called 'Start Speed', that specifies the value where the controller begins ramping the power from Min to Max power. If the laser is moving at this speed or slower, only Min Power is used. This setting is 10mm/sec by default on Ruida controllers, but some machines may have it set as high as 15 to 20 mm/sec, or may have it set lower.
