In March there was a vote that passed to complete the CNC area. You can read the entire thread here https://groups.google.com/forum/#!topic/cincihackerspace/OBw7YK-TEZg or read my summary in bold below.
I made a proposal at the meeting last night on a plan to get our CNC area finished and ready for certification and classes. I have already talked with Dustin and Brad and they are on board with helping to get these things accomplished. I am giving us a time frame of 4 months (through the end of July) with the hope we can finish sooner.
Here is what I propose:
-
Finish the CNC machine by finishing up the wiring, endstops, and auto squaring.
-
Organize and clean the space so everything is easy to use.
-
Create/make a CNC station to hold the computer and all tools that you would need while using the CNC.
-
Work with Dustin to create a clear path to certification along with direction and materials to reference while using the machine.
-
Large sign to display the steps needed to have a successful cut
-
Videos to show each step
-
Written handbook to also provide these steps
-
Have a budget of $200 to be able to purchase miscellaneous items like small tools, endstops, etc (I will provide receipts at the end of the project to show all money spent on the project.) This budget was above and beyond the Warden budget
If you have any questions or input on this proposal please let us know as we are open to suggestions.
- John2pt0 suggested that we enclose the CNC tower
Not long after this passed Brad, Dustin, & I got to work and started working on layout designs for the CNC area. In our floorplans we included using the “Medium CNC” that I currently own that sits next to the dust collector (we do not plan for it to sit there). After some members saw that we were including this machine in our layout they expressed concerns for having a member owned tool in our space that our group would be responsible for any maintenance/repairs. Once these concerns were expressed all further planning was halted until we could figure out a solution that our membership could agree on. This was brought up at the meeting last night and below are a list of some pros and cons that were mentioned. I am for having both machines so I have provided rebuttals for the Cons listed below. I encourage everyone to also voice their opinions in this thread so we can have a good discussion on how we should move forward.
Cons
-
We only need one large CNC because we have a limited amount of space.
-
With a new layout and some organization it’s my opinion that this space will be much more utilized than before.
-
We do not want to be responsible for a machine that breaks that isn’t ours.
-
If someone misuses a machine it’s going to break no matter what. It doesn’t matter if it’s the Hive’s CNC or mine. The machine we are talking about keeping has cheaper parts (spindle, steppers, drivers) and would be cheaper to fix if any damage occurred. To date I believe most of the damage that has been caused on our CNC has been due to lack of training. Hopefully having a proper training course will curb any future misfortunes.
-
We do not want to spend any money on upgrading any machine when it could leave the space at any time.
-
I do not think we should spend ANY money updating this machine. Also as long as I’m giving training classes and the machine is getting used I have no plans to remove/sell it.
-
Some members believe the Hive should get away from having any member owned machines.
-
In the past we have been very open to non Hive owned equipment being on loan to our members. If we decide to remove all non Hive owned equipment then at that time we can discuss if this machine is needed and if we would like to purchase it or a similar machine.
Pros
-
Having two machines will make it much less time consuming to give classes to multiple people. In our classes we plan for people to be able to each make their own item (yet to be determined) to bring home. I’ve taken a CNC training class at The Manufactory and it’s kind of a buzz kill to wait on everyone to make their first cuts.
-
Sometimes using the CNC can be time consuming and cuts can take hours at a time. Having two machines would allow for multiple people to work at once OR allow one person to be making two cuts at once.
-
When new members come to our space it seems that there is a large percentage interested in learning about the CNC. If this trend continues along with some community outreach to teaching classes, it’s my opinion that we may have a real need for multiple machines.
At the end of the day I’m not asking for this machine to be here permanently, though I’m not against it either. I would just like the ability to continue working on our original plan to make our CNC machines safe to use, organize the area, create a curriculum, and hold regular classes for current and prospective members so everyone can properly use these machines. Once everything is complete, and after several months of training and classes we will have a better idea if a second large machine is really needed. If it’s not getting used and just collecting dust I’m the first person that will suggest that we should remove it. It’s easier to keep it here for this trial than to find another one down the road after it’s gone and we decide we want it.
