Not Enough Extended Space Error

Alarm message of LCD panel—No enough extend space

LCD panel shows the following information:

This problem only appears on engraving mode, it’s caused by the buffer distance is out of bound.
For example, if you want to engrave a picture of 200×200mm, you move the laser head to the top left corner of the working table and press the “Origin” to set the starting point.
When you press the “Start” button to start engraving, the failure warning would appear.

How to fix this problem?

Press ESC at first, and then move laser head a distance away from the edge to leave enough buffer distance.

If you are using "User Origin"
Now set a new starting point by pressing the “origin”, you will find the problem was fixed when you run the job again.

If you are using "Absolute Coordinates"

Move the artwork in Lightburn, send to the machine and overwrite. Reload and try again.

If you are using "Current Position"

Move the head further away from the edge of the bed and start the job again

Why does this happen?

When the machine is engraving in high speed, the actual moving distance of the motor is usually large than the graphic.
Therefore, we need to keep enough buffer distance on the two sides of the graphic.
The buffer distance will be longer as long as you set faster speed, so we need to keep more buffer distance when the speed is higher

(Buffer distance out of working table)

(Buffer distance within the working table)

Here is the space needed shown in the Lightburn preview:

Lightburn Preview may show the extend space inside of the machine bounds (when in absolute coordinates, user origin and current position will not be reflective of actual start position) but the Ruida Controller on the machine will want a slightly larger extend space buffer.
