When I purchased this really cheap mill I always had the intention of converting it to CNC but once I started using it it became clear I had to. It was so unwieldy to use and resulted in many destroyed parts. Due to its small bed and limited capabilities I feel like will be mostly using this for cutting PCBs or plastics. This project is currently in the parts gather stage but I have most of what I need to get started.
Animatics Integrated Servo System motors
I think these are smarter than me...
It's an RS232 connector with the addition of two large power pin.
Flex Shaft Couplers
Connect the motors to the mill
ATX style power supplies.
These will be daisy changed together to achieve 24v at ~21A
I've finally cleared some time and have been really motivated to get this project moving along lately. Yesterday I printed a bracket for one of the motors with the hope of starting to work out some of the hardware while getting the PS in order. I'd did though accidentally print a NEMA17 instead of a NEMA23. Derp.
Regardless of this minor setback I decided to get started on the PS today and with only about 30 minutes in I have 24v out! The instructions posted in the links were a perfect explanation on what needs to be done. Only difference I noticed was I didn't need a resistor across pins 14/15 but rather just bridging worked.
While this is showing the highest output of ~24v that will be used for the motors, I also get 5v (for running the micro) and 12v (not sure if I'll use) from the first supply in the chain. And the second supply gives a not very useful 17v on the original 5v line.
Next step will be building up a case for this and printing the correct mounting brackets. I'll also be waiting on several parts. So far I need at least the 7W2 connectors for the Animatics motors and shaft connectors.
Added link to the PSU design I will be implementing. Basically chaining the two ATX power supplies I already have together to get 24v @ some beefy amps. I read before I should be able to get upwards to 21A but cannot find that resource.
