I have made some adjustment to the room rental. Please checkout my original post here for the update. In summary the rooms are available for 350$ excluding membership fee. You can also rent half of a room. If you start in the middle of a month, the rent for that first month will be reduced. We would require a damage deposit from every renter. We would require 30 day notice from the renter if they intend to stop renting a room.
I am renting half of the room that currently has a bunch of random stuff in it. I am renting it for July and August so that @fullmetalbuddha and I can develop our super secret product for market. The first prototype will be for sale or auction to raise funds for makerspace.
There are still 2 full rooms and 1 half room available. If you have been working on a cool project and want to take the leap and turn it into a business, this may be an excellent opportunity.
Wherever we put the machine we can maintain it at a positive air pressure like I did with the shapeoko computer upstairs. This will prevent dust from entering the machine by having filtered air leaking out any openings. We need positive pressure as part of the ventilation system anyway.
Yep, I’m pretty sure the one in the office is already wired to talk to the doorbell, so tracing out the wires and putting some on the other floors would be handy. If we can link up to the electric strikes we already want to put in, so much the better. Failing that, we hack them into network-connected intercom units and tie them to the infrastructure that way. Regardless, they are a nice set of parts to provide features we want.
A co worker of mine showed me a cool mod he did to his Cell phone. Took the lens out of a cheap Dollar Store Laser pointer. Cut a piece of tube that the inside diameter matched the outside diameter of the lens. Then mounted it in front of the camera on his Smart phone. Now you have a 130x zoom. We used it to find where the the helium leaks were on a cryostat.
Was in this evening looking at being able to set the speed (RPM) of the spindle.
Made an important discovery … the spindle has been rotating backwards all this time. So, rather than cutting the material it was beating it to death (wood) or melting it. We reversed the spindle direction (just flipped 2 of the 3 leads going to the motor … any 2 will do it) and suddenly it was making an awesome cut in plastic where before it was melting it.
We also managed to change the spindle speed manually by setting the maximum spindle speed (p105) directly on the controller. For plastic we were getting better cuts at a spindle frequency of 115 Hz and a feed rate of (@arasbm what was the travel speed?).
We are still figuring out how to set spindle speed and rotation (forward or backward) directly via LinuxCNC.
