Re: CNC Construction Set
I needed to cut some angle iron for a project I am working on. Once my angle iron fixture was installed the torch could not reach the proper height with the CAP 04 installed. Back when I had to double the height of the riser blocks, I kind of Knew I was going to have to redesign it. KRCCS gantry.jpg...

Re: CNC Construction Set
I just got the new gantry built. _MG_9973.jpg Its a more conventional X axis. Next I have to design the X carriage. The sides of the gantry will have braces that will tie the X beam to the risers. These braces will also act as the motor and bearing mounts. To do this however I have get my inventor 3...

Re: CNC Construction Set
As for the CAP04 THC. Here are some things I dont like about it. 1. Since its capacitance base the aluminum Y carriage riser blocks interfere with it when you get within an inch or so of the left side (side the CAP04 is mounted on) This means if using the THC, you loose over an inch of X travel.

Re: CNC Construction Set
The cost of building the CNC Construction Set Plasma will depend alot on what you have on hand. I had most items on hand, including the G540 which is one of the most expensive parts. The G540 is probably a little much for this build so you could get by with something a lot cheaper. If you change to ...

Re: KRMx02 Vs KRmc01 cutting metal
Something very important about a mill, is its ability to drill. Unless you are using a very small drill bit, CNC routers don't have the low end torque and spin way too fast. I wont even get into the downward forces (for drilling) you have with a mill. Most routers can not take that kind of force.
