Laser Cutter/Maintenance

Running cost
- The tube is £250 for 1000 hours
- The lens+mirrors are £150 for 250 hours
- The power is (say) 1.2kW at £.2/kWh.
- So 250/1000 + 150/250 + 1.2*.2 = £1.09/hour
- The space also used a large chunk of funds to get the cutter, this needs to be recouped.
Therefore a recommended donation of £5 for each hour of use would be greatly appreciated.
