Ortur Laser Master Service Notice - Static Build up

Release Date: 10-02-2021 (UPDATE Date: 10-03-2021)

Ortur Action Advice: UPDATED – Recommended

Some users have been reporting and experiencing Static Electricity build up in their machines while in use, especially on raster engraving operations.

This build up of Static Electricity can become severe to the point that its discharge – via the 12v rail – can cause the motherboard to reset. Therefore causing interrupted engraving operations (Alarm 3/Connection Lost errors).

In extreme circumstances the static build up might lead to hardware damage.

Although the number of users affected by this situation is statistically low, Ortur will implement mitigation changes in the hardware to address this issue.

The guide below explains how to implement similar mitigating actions on machines that are already in users hands.

Ortur Grounding

UPDATE on Grounding Kits: ORTUR finished manufacturing and is ready to start shipping for all customer that does not feel comfortable performing the above guide. Please inquire via Ticketing system for availability.


After a month of research and a heavy investment on research machinery ORTUR developed a Grounding Kit that will be sent to all customers that require it to retrofit on the Ortur Laser Master 2 already in user hands.

The conclusion of the research done shows that connecting all Ortur Laser Master 2 elements increases the surface area enough to mitigate the static build up without the need of grounding the machine to Mains Earth.

The Kit consist of an additional cable set, that replaced integrally the Y Limit switch cable. Below a simple overview of how the wiring should be addressed with the Ortur Grounding Kit in order to mitigate any Static build up in the Ortur Laser Master 2 Frame.
