CNC Machine Project Day 5

Today I worked on finalizing the electronics case. This meant finishing the fa mounts and the case mods, as well as ordering fans to mount. I also then worked on getting the stepper drivers mounted and then I went to work mounting my signal generator. This has left me with a very clean looking case and space for wiring and other electronic attachments. I also think that this case will help the CNC look more professional because the wires will be contained and the whole system will be cooled at the same time. Looking to next week I will need to spend time on wiring but I will be starting to assemble the frame of my CNC machine.

Weekly Reflection 1 This week I made good progress towards understanding, and assembling the electronics system. This has culminated in the creation of my electronics case for the machine. As of right now I have finished all the necessary physical mounts and mods, all that is left is to wire it up. This week I learned a lot about how stepper motors work, and how they interact with the drivers to get them to work. I also have been learning about G-code, the universal machine code language. It is useful to know when using a CNC because you can proofread the code live on the machine, as well as being able to edit and and insert parts on the fly. This can help a lot when troubleshooting a program on the CNC.
CNC Milling Machine Project Day 4 Today I started out working on finalizing the fan mounts. This will include going to the metal shop to remove some of the aluminum where it would interfere with the airflow of the fan. After I finished my work on that I went down to the tech center to get some old scrap ethernet wires that I will be using as my stepper signal wires. I then started trying to wire up and example driver with my hardline cable, this was hard as the cables were brittle and would sometimes break off in the terminal blocks if I moved them around too much. I think that I might go to start using the patch cable with soldered ends. This would make the connection way more durable because it would be more flexible. Tomorrow I will be able to wire up and hopefully start testing stepper motors proving I find a way to wire the AC power to the stepper’s PSU.   

Week 2

Day 7 Today I worked on the wiring and the cable management inside the case. This meant I had to make signal and power wires for all the drives, and eventually wire up the PSU’s to power. I also took the time to install all of my fans, and the signal generator meaning all that is left is to work on the computer and the wiring. At the end of the day I started to do work on the internal power cables, They are almost done I think that I will finish them up tomorrow and then go and start to work on the base. Day 8 Today I did start work on the base of the CNC, I went down to the metal shop to start setting things up, and to move my materials over. This took a lot of time as I had to do a lot of setup work on the horizontal mill to be able to accommodate parts of the size that machining. I had to indicate and line up to two vises gapped by the entire 30 inch table. I also put the cutter I am going to be using on the machine, as well as setup the spray coolant sy...
