For several years now, I have had the desire to build my own CNC Router. However, after many hours of reading Posts on this Forum, several attempts at building the basis of a machine, I finally gave up, although I still had to have a CNC Router.
Now, I have done it the easier way. Having recently retired, I decided to purchase a home built CNC Router that suddenly became available.
After driving to Adelaide to collect it in my Ute, I have managed to put it back together. Correctly, I hope.
I have pictures but as yet have not loaded them into the computer, so for now, a brief description will have to suffice.
Stepper Motors x & y axis 430oz-in, z axis is smaller, also have spare 430oz-in, ie.4 motors total.
3 x M542 Microstepping Drivers
2 x 40vdc Stepper power supply
1 x 12vdc power supply
for interface between motors and computer is the C11 break out board from CNC4PC
Emergency stop button, Microcontroller based Safety Charge Pump
Steel Frame construction, with structural aluminium gantry
Y axis Linear rails - vxb bearing blocks on 20mm x 1600mm solid ground hardened steel.
X axis linear rails and leadscrew is salvaged from an old IBM pick and place machine. lead nut has some slack in it.
Z axis constructed from solid aluminium plate, has nsk? i think ballscrew, with nsk? linear bearings 16mm dia.
Brand new miluwakee speed adjustable die grinder 7,000 - 30,000rpm
Shop Vac for the dust 1300watt, 5m long hose
I also have a variety of endmill/slotdrill/ ball nose cutters.
However, I am reluctant to switch it on until I am more confidant that I have hooked all the wiring up correctly. Some of the Posts that I have read have mentioned 'Blue smoke' and that seeing it is not good.
Given my level of expertise in electronics, I have probably wired the ON switch to the blue smoke release circuit.
I really don't want to see that blue smoke.
I live in St. Albans, and would appreciate it if someone who knows a lot more than I do, could spare the time to visit and and check my machine to make sure it is safe to switch on.
Just send me a PM and we can go from there.
Did I mention that I am very keen to have my machine running.
P.S. Knowing that pictures are very important to everyone, I will get onto them and post them tomorrow.
