Re: My geodome greenhouse project
It only took me 2 years, but I am finally tackling this project. @colin and another friend come over to give me a hand. I will post the instructions and more picture when the frame is put together.

RE: Our 1390LC Laser Cutter
so @pierre and I did a quick inspection today after the workshop. The laser is out of alignment. It also not hitting in a round circle shape as you would expect. This may be due to damages mirror or lens, or hitting side of one of the mirrors on the way. We need to set a few hours aside and do a full inspection and realignment of the mirrors.
I do not think it is unsafe to continue to use the laser for now, however you may notice reduce cut quality.
RE: Makerspace FirstAid Workshop - May 4th
I also like to thank Twila and @Torren! I never had the opportunity to take a first aid course before and this crash course today was very informative and packed full of great tips. Really appreciate all the time and effort you two put into this. Also, everyone else participating in the workshop were awesome. So happy I could make it.
RE: Im interested in a "Froggy Mill" CNC 3020 instruction class.
I used to run these workshops. If there is enough interest, I could schedule something for two to three weeks from now.
If anyone else wants to help me run this workshop please let me know. It would be great to get more people using the froggy mill.
In the past the workshop focused on doing simple 2.5D carving based on a vector image. The best free tool I have found for that is easel.
More recently there has been a few cool 3D CAM applications made available for onshape which I would really like to try on the froggy mill. If this works out successfully, we could also add that to the CNC 101. Check out this video to see what I mean:
RE: Farmers market
@pierre thanks for dialing me in here, but if I do go to farmers market this year, I would have to get a table to sell my own farm products. We can not sell both farm produce and makerspace stuff on the same booth. If we both go on the same weekend, I could ask market manager to put our booths next to eachother, they were open to that last year.
One thing the farmers market board were emphasizing a lot, was that items that we sell at the makerspace booth should be made by makerspace members and at makerspace. However, if there are things there just for show and not for sale, they seemed ok with it. It is a great way to get you product introduced if you targeting local market.
Another important thing is that if you commit to the table you need to be there early morning and set up before the market starts and be there untl market ends. Market manager and other vendors really don’t appreciate when people set up late, or leave early.
RE: Our 1390LC Laser Cutter
When the laser arrived, to my surprize the beam was perfectly aligned. The method described on the manual was not ideal though, it makes a lot of smoke and can get the mirrors dirty. I really like this guys technique and I think this is what we should do:
However, aligning mirrors should be the very last step of maintenance, after we have done all the other tasks. We should first do all the other choires like cleaning the bed to adjusting the belt and cleaning mirrors. Before attempting to align the beam, we should also make sure the nozzle is straight. I have noticed a couple of times, the nozzle has been sitting on an angle and the beam hits the edge of the nozzle which causes the beam to reflect and hit the material in a C shape.
Some important point to reiterate from the manual and the video: it is not important that the beam hit the center of the mirror – as long as the beam is aligned. This means hitting the mirror in the same location at the minimum and maximum location of each axis. We would also check that the beam is relatively round.
I will start a google document and share it with you guys, so hopefully we can write a complete maintenance manual in the next few days and build a solid maintenace team.
