I am planning to convert a TITAN TM16V milling machine to CNC, I am waiting on delivery
of the machine which is being shipped monday along with a TL210V Lathe which will also be converted.
I have the ball screws and ball nuts, 5mm pitch, though they need to be cut to length and machined.
Here is a link to Titan Machinery for anyone interested
I have recently received my Geckodrive G540 controller, 378 Oz-In Motors, 48v 12.5 Amp PSU and wiring from
AusXmods - Modify Your World
Their prices were good.
I took a number of photos of the controller. After close inspection I noticed not all of the transitors made good contact with
the back plate of the housing. Since this back plate provides a medium for heat dissipation I decided to disassemble the
controller and add some silicone heat transfer paste to the Transitors. I don't recommend anyone else doing this as it
may void any warranty, do at your own risk.
The motors I have choosen are rated at 3.5 amps, the max power handling of G251 controllers inside the G540 so efficient
cooling is important.
Back panel removed, also two of the four G251 controller boards removed from housing, two remain.
Showing the Transistor side of the G251 controller, the side that contacts the rear of the encloser for cooling purposes.
The other side of the controller showing the connector that interfaces with the board housing the DB25 and BD9 sockets etc.
The next photo shows two NEMA 23 stepper motors, the larger, one of four that came with the kit, is a 60mm frame size, the smaller one, one
of two I had laying around is a 57mm frame size.
I will be posting more photos and so on as things progress and will add some closeup shots of various aspects of the project to create a concise visual
experiance of the project for anyone thinking of doing the same with a Titan Mill or Lathe.
