Kerf Adjustment Using Lightburn
To get better fitting components that are cut on your CO2 Laser, you may need to adjust the ‘Kerf’ by using compensation within the Lightburn software.
Download the ‘Kerf test’ lightburn file and jigsaw file to follow our video tutorial.
Mirror Cleaning Process On Your Lasertech
Keeping mirrors clean on your CO2 Laser cutter is an important, daily maintenance task that should be completed carefully. This ensures that your CO2 laser can fire the beam onto clean mirrors, reducing the risk of bad cuts and damage to the mirrors.
This simple task will help to keep your laser running in an optimum state. (remember to place your mirrors back in the correct way after cleaning).

CNC Router Vacuum Bed/Sacrificial Surface Best Practices
The concept of a vacuum bed is to pull together the surface of the component/board being processed, to the surface of the sacrificial board, creating lateral ‘friction’ between the two surfaces.The more surface area in contact, the more lateral grip can be achieved.
Large Surface area = more ‘grip’
Porous products tend not to ‘seal’ as well as ‘Non Porous’ such as Acrylic for example, as air can pass through them but these tend to have a ‘rougher’ surface creating more friction between the sacrificial board and the product, compensating.
Alternatively Non porous materials i.e.Acrylic, ‘seal’ better so more pull down force is achieved to compensate for the smoother surface.
The correct size of neoprene gasket must be used, and one single length ‘per zone’, limiting the amount of joins to just 1, where air can be sucked through losing pressure applied to that zone when the component is placed above. Therefore restricting the flow, creating the ‘pull down required. It is important that the channels are completely free of debris and the neoprene gasket is not ‘stretched’ to fit in the perimeter channel, as this reduces the diameter of the seal causing an uneven surface for the sacrificial board to sit on.
The seal must be laid over the perimeter groove of each zone and firmly pushed directly ‘down’ into the groove. When the perimeter is complete, the seal must be carefully cut and ‘butted’ together to complete the seal.
When the sacrificial layer is placed on the seal and the vacuum is switched on, the sacrificial board compresses the gasket if the zone is sealed correctly.
Once all Zones have the gasket fitted correctly the vacuum can be switched on and all pipework joints can be checked for leaks that may be causing a pressure drop in the circuit.
Again the concept of each ‘zone’ is that air can only flow through the fibres of the MDF within the area of that zone and directly in contact with the component being processed above. This effectively seals the circuit and affords maximum pull down on the component creating the lateral friction required, allowing the Vacuum pump to do its job.
In order to ensure the best possible lateral grip on the component, it is essential that both sides of the sacrificial surface are skimmed. This removes the ‘skin’ created during manufacture and increases air flow through the fibres of the MDF. This also ‘levels’ the sacrificial surface for accurate machining depth. You can purchase special tools for this from around £100 which save a considerable amount of time on large bed surfaces.
General CNC Router Maintenance
Your Mantech CNC Router will provide you with years of productive service if maintained correctly. To aid with this there are a range of daily, weekly, quarterly and yearly maintenance steps that should be undertaken, the below is based upon a 45 hours per week production cycle.
The following maintenance tasks should be completed at the beginning of a production shift on your Mantech CNC Router:
- Wipe down guide rails, clean out racks and re-grease
- Keep the table and general machine surface clean and tidy before and after use
- Remove, clean and inspect cutters to ensure they are in usable condition
The following should be completed at the start of your shift on a weekly basis:
- Complete all daily tasks
- Clean the CNC thoroughly to remove and excess grease grime and swarf
- Check and clean the filters on your vacuum pumps and cabinet
- Check oil levels in the lubrication system and fill if necessary
- Check your accessories general operation and cleanliness including your dust extractor and the optical surface of your light guards
The following maintenance tasks should be completed at the end of the production shift on your Mantech CNC Router:
- Complete all weekly tasks
- Grease all of the linear bearing cars including clean and lubrication of rotary bearings where accessible
- Clean any racks and screws with a scrub brush and degreaser
The following tasks should be undertaken at the end of the last shift on a quartely basis:
- Complete all weekly tasks
- Remove X & Y axis motor covers to inspect transmission or gearbox for belt wear and cleanliness
- Check the table and bridge bolts for any play, tighten if needed
- Check the vacuum bed condition and clean vacuum ports if necessary
The following maintenance tasks should be completed at the end of the production shift, bi-annually:
- Complete all quarterly
- Turn off the power, isolate and carefully vacuum out any debris in the electrical cabinet
- Clean all accessories including the vacuum pump filter, empty any extraction bags
- Check integrity of belts on all transmission, replace if necessary
- Check integrity of bearings on all transmission and replace if necessary
- Follow standard power-up procedures and complete a thorough check-up of machine operation
- Check machine levelling of bridge and bed.
- Electrical connections checked and tested for integrity
- E-Stops to be checked and tested for integrity
- Pneumatic pipework and systems checked
- Spindle integrity (speed and alignment)
- DSP/PC Parameters checked and set correctly
- Homing Sensors/Positioning Checked
Bi-annual maintenance should be undertaken by a competent engineer. Should you wish to book in an annual service please contact us on firstname.lastname@example.org or call one the team on 0121 541 1444.
