How-to: Improve engraving quality of laser machine
If you want to improve engraving quality of your laser machine, try a simple setup procedure – adjust Reverse Interval.
Step 1: Initial Data
Chinese laser machine
Table: 500×300 mm
Laser tube: 40 watts
Program: RDWorks
Step 2: Engraving Parameters
Run laser cutting program and draw small square with sides 10×10 mm.
Set engraving parameters
Processing Mode: Scan
Power (%): 30-40 (For 40 watt laser)
Speed (mm/s): 300
Interval (mm): 0.4 (This interval allows you to distinguish between engraved lines)
Engrave the image.
Look at the square with a magnifying glass. If even and odd lines do not
dance and lines are aligned horizontally – then everything is fine.
Otherwise, go to next step fot settings.
Step 3: System Setting
Open System Setting window: Config > System Setting > General Settings
Set Scanning (Reverse Interval) check box.
Add the following string values
Speed (mm/s): 100 | Reverse Interval (mm): 0.10
Speed (mm/s): 200 | Reverse Interval (mm): 0.15
Speed (mm/s): 300 | Reverse Interval (mm): 0.19
Speed (mm/s): 400 | Reverse Interval (mm): 0.23
Speed (mm/s): 500 | Reverse Interval (mm): 0.25
Speed (mm/s): 600 | Reverse Interval (mm): 0.28
These values are valid for our particular machine instance. You may have other values.
Step 4: Square
If even lines (second line) are to the left of odd lines (first
line), increase the value of Reverse Interval (Figure 1), otherwise
reduce (Figure 2).
Adjust values for the Reverse Interval and engrave the square until the lines will align horizontally (Figure 3).
Do the same for all engraving speeds that you use.
Step 5: Vector Logo
Look at the quality of engraving
Without adjustment Reverse Interval
With the correct setting Reverse Interval and the value of Interval (mm): 0.1
For better engraving, set the value to Interval (mm): 0.05

I am a beginner at CNC, I’ve never used a CNC machine before and with in a day I was carving. An awesome machine for a beginner to learn as hobbyists. I used the manual and the help video. One hour to assemble and test, very friendly and easy to use. It’s a good buy for the money. I would definitely recommend this machine to someone getting into CNCs.

1530 CNC Plasma from Australia
This CNC plasma cuts very easy Very good machine .
But I also recommend purchasing the nozzles and the tips of the torch consumables oarts they wear out quickly and for a good operation they must be in good condition.
