• Install MESA

• • dust extraction

There is a hole at the top rear left of the cabinet which may be used for dust extraction - either a separate unit or a connection to the shop extractor. However, the cutting dust tends to lie around the cutter so some means to move it to the extraction is required. Possibilities are throwing it into the air and then extracting the air, or sucking directly at the cutting tip. There is a small air pump in the cabinet whose output is taken to a connector under the gantry parking position. This may be used to disturb the air near the cutter, and a flexible hose to the extraction used to remove it. The hoses needed may get in the way : this requires some experiment. A dust shoe may be helpful but will hide the cutting point from view.

• Prepare Inductions
• AC Node

Collets

• We are using ER 20 collets
• You will need to provide your own tooling
• Use of collets ER Collet Essentials. https://www.youtube.com/watch?v=WKikm6cQKh0

Materials

• This is in the woodshop and to be used on non metal materials only.
• No liquid or mist coolant is to be used in the machine at all.

Risk Assessment - CNC Routers

This risk assessment is intended to provide guidance on the risk associated with the above equipment and activities in normal use. Please also check general risk assessments for the space as a whole. Any discrepancies, errors or concerns should be raised with the document maintainers or trustees - do not edit this assessment directly. For responsible persons and last update, see 'version log' of the assessment page.

Activity

Cutting wood, metal or suitable plastics on the CNC routers

Understanding Risk Rating

LOW - Ensure current control measures are in place and continue with activity

MED - Control measures may be adequate, co-supervision is recommended

HIGH - Do not undertake activity without further consultation with area specialists

Risk Assessment

Identify Hazards	Who May be Harmed and How	Severity	Control Measures	Likelihood	Risk Rating
Incompetent user	User, Bystander	HIGH	Users must not use tools that they are not competent to use.   Members must challenge use that they believe is dangerous.  Users must read the risk assessment before using a tool.   Users must complete induction before use.	LOW	MED
Contact with router bit	User	HIGH	Do not touch moving parts of machine once in use   Do not put hands into exclusion zone (within 30cm of router bit).   CNC should be switched off immediately after use   Spindle should stop within 10 seconds of being turned off.    Use guard/ doors if available	LOW	MED
Ejection of workpiece (Kickback)	User of the tool, users of the room, the space.	HIGH	Check that material to be cut is fixed securely to the bed before switching the machine on. Take particular care when working with smaller pieces of material to ensure the material will not move.   Use tabs on your design file whenever you are cutting through material completely.	LOW	MED
Dust (inhalation, fire, explosion)	User of the tool, users of the room, the space.	LOW	A respirator or mask should be used whilst operatingun-enclosed tools for prolonged periods	LOW	LOW
Blade snatching or jamming	User of the tool, users of the room, the space.	LOW	Do not exceed the recommended feed and speed settings on the CNC   Do not exceed recommended cutting depths   Make sure that your material is free from foreign objects.   Do not make a cut that exceeds your material depth.
