1.9 General Safety Measures
The CNC gantry milling system is only to be used in a technically perfect condition which is to be ensured prior to each
operation.
The emergency stop switch as well as, if applicable, additional safety devices, always need to be easily accessible and
fully functional.
Avoid exposure to the eyes or skin to direct or scattered laser light. This poses a high risk of injury!
Use personal protective equipment. Always wear safety goggles and gloves to protect the eyes and skin from direct and
scattered radiation.
1.10 Notices Regarding the Emergency Stop Switch
The emergency stop switch of the DL445 is located on the control unit (refer to „3.2 Drawings Control Unit"). Position
the control unit in a way that allows you to easily reach the emergency stop switch at all times. The emergency stop switch
of STEPCRAFT machines is to be found on the front side of the machine or in a separate housing, that can be positioned
at a suitable place with a magnetic disk. This depends on the machine series. Refer to the manual of your machine for
more information.
If you would like to use a system-guided tool like a milling spindle of another supplier which is equipped
with a separate ON / OFF switch and is NOT controlled via the PC, you have to make sure that it is profes-
sionally connected to the emergency stop switch. If you neglect this, the tool will continue running even if
you actuate the emergency stop switch. There is a considerable risk for personal or material damages!
The emergency stop switch can only effect the stop of all components if these components are electronically
connected with the emergency stop switch. Be sure to test the functionality of the emergency stop switch
before using the machine. The switch has to be capable of stopping the entire machine in case of an emer-
gency!
By pressing the emergency stop switch, the emergency stop is triggered. The power supply of the control is interrupt-
ed. Additionally, the control software receives the signal to stop the operating process. The machine stops immedi-
ately. An emergency stop will result in the stepper motors losing steps. Your machine has to be homed afterwards!
To cancel the emergency stop state, turn the emergency stop switch clockwise. This reactivates the control system.
A controlled stop of the machine can only be achieved via the control software. If you want to use a system-guided
tool, such as a milling and drilling motor, that features a separate ON / OFF switch and that is NOT controlled via
the PC, you have to make sure that it is expertly connected with the emergency stop switch, for example by use of a
Switch Unit for electric consumers (EU Item 10052, US Item 10129). If you do not comply with these requirements,
the system-guided tool will continue to run although you have activated the emergency stop switch leading to a high
risk of personal injury and damage to property! For connecting the Laser DL445 with the Switch-Box, the 2. Layer
Module is necessary (EU Item 10703, US Item 10703). If you are using third-party products, such as another CNC
router mainboard, you are solely responsible for connecting the emergency stop functionality properly to the DL445
control unit / CNC machine. If you have any questions, please do not hesitate to contact us! You can find our contact
details on the cover sheet or in chapter „10 Contact".
