Setup

In theory, setting up the Roomark Laser Engraving Machine should be a straightforward process. The setup itself took about 10 minutes, but getting around the SC7A20 chipo which detects acceleration and tilt angle values.

For common questions regarding LaserGRBL setup, check out the LaserGRBL FAQ.

Step 1. Connect Roomark Laser Engraving Machine to rated power supply

The power supply for this engraving machine must be at least 12V 5A.

Defines GRBL configuration used by Roomark Engraving Machine

Ensure that $53 is set to 55 or more, in multiples or 5.

Note: Initially, I had trouble getting the engraver to work due to tilt angle and shock and movement detection. This sensor activated almost every time the engraver moved. After troubleshooting, I set the $53 value to 55, and the engraver began working. This is an essential step, and engraving will not work without it.

Problems

I ran into an issue where the machine was stopping due to tilt angle and shock and movement errors being thrown. For hours I troubleshot both LaserGRBL and the machine, with no success. On a whim, I modified setting $53 in LaserGRBL, which is proprietary to Roomark's Laser Engraver. The value must be a multiple of 5, and 55 or more. It relates to its detection of tilt angle.

Conclusion

Overall, it was a very fun experience, though frustrating at times due to Roomark's lack of documentation on their product! The setup took several hours because I did not know how to fix the tilt angle and shock and movement detection triggers.

I will continue experimenting with Roomark's Laser Engraving Machine to create cool art pieces, and perhaps even find new uses for laser engraving.
