While I know it is an unpopular topic, we will be increasing the cost/min to run the laser around Jan 1.
It will be now $1/5min. This is being done to allow for a greater margin for replacement parts. (and perhaps some accessories too. 
)
This is just a notice. No need to reply.
At the suggestion of a board member, William & I discussed this and have decided to set the new rate at $2 for each 10 minutes (rounding up, 10:01 = 20 minutes) for the Laser usage fee.
This is effective immediately.
This better allows for purchase of consumables and upgrades. It is our hope that it will soon include the option to use these funds toward the purchase an additional laser.
