I am not done yet but I wanted to post an update pic.
I am doing a 30x30 build in PETG. There are a couple of ABS parts in the corner pieces that I printed when I ran out of PETG but nothing pivotal.
Electronics as follows:
Motors: recommended NEMA 17s
Boards: ramps 1.4 with LCD both in printed enclosures (I still need to get a fan for the ramps board)
Power: PC power supply putting out 50 amps on the 12 volt rail at I think around 80 to 90 percent efficiency. Its a Roswell so pretty good efficiency. I do not remember the exact numbers since its been a couple of years. (I know that its a serious overkill but I happened to have it around so it was free)
Tool: I have an Rotozip around that I plan to use for now. I hope it works out because I have never found anything good to do with it before this. It is not quite the beast that the Dewalt is but its what I already have.
Everything is pretty standard so far. I have a MDF top for it. I need to build out the frame but that can be done in an hour or so. I have printed up the rest of the center and feet as well it is not pictured here though.
The build has been relatively smooth so far. I had to re-print a lot of pieces because I had a setting off in S3d. Once I corrected that, everything fit together great.
Once I am done with the table, the power supply and ramps will be under the table while the LCD will sit on top with the MPCNC. It should be much cleaner looking.
