Decided I need a CNC plasma cutter for my own projects as well as to make a few bucks on the side. Thought I would share the build here for others inspiration/feedback/ridicule
Fist problem was I do not have a garage or workshop. To remedy that without blowing all my funding I picked up a 20' Shipping Container that I am going to convert into a small workshop. I would have liked something larger but this will have to do for now. It's now installed and sitting on concrete peer blocks. Full conversion to workshop will wait until I get the Plasma built....I don't want to have a petty shop and no money left for a plasma. So on to the plasma table build!
I originally wanted to be able to cut full 4'X8' sheets but I've decided to cut that in half. It should better fit the sea can while still allowing a bit of space for a small work area . I'm going to have to be very organized!
I will be adding a water table and plate marker as well.
For a good price I picked up a used Hypertherm Powermax 1000 that looks to be in great shape. It has a hand torch that I will probably use/convert until I can upgrade to a machine torch.
For electronics I have an order in at CandCNC for their kit: BladeRunner Dragon Cut 620-4 EtherCut + Digital Torch height control IV, Feather-Touch Sensor, and connection kit for the Hypertherm.
Software will be Mach 3 and SheetCAM
Decided to design and build my own Z axis. There are a few available to buy on ebay but I'm picky/OCD so I didn't want to risk it. Designing the Z axis (6” travel) has turned into a larger project that I expected. Most of it has been due to the fact I have decided to design it all in Solidworks. I'm a machinist and use Mastercam daily Solidworks is...different but so far I really like its capabilities.
Z axis design at the moment
Home switch Position. I'm also adding over travel switch. It is not needed when using stepper motors but I feel better using them for the small expense.
