I'm starting my g0704 conversion. I bought the conversion DVD from HOSS and the information has been very valuable. I am doing kind of a hybrid conversion and have purchased the parts from Billy. They are very nice!

Many thanks to HOSS for answering my questions and for the g0704 conversion DVD.

I am using HOSS's recommended electronics but have switched the power supply to a transformer based Antek 50V 600W with 12V and 5V regulated supply. I have used an Antek PS in my Joe's hybrid for many years now with very good results.

Components:
- CNC stepper mounts from Billy
- 3x Keling KL-6050 Stepper Drivers
- 3x Keling Nema 23 570 oz-in Steppers
- c35 breakout board

I'm starting the build with my controller.

I am using an Antec 300 PC case as the enclosure. I am using a latching control circuit with a contactor to turn the ac on and off on the power supply. See #3 here Contactors and Control Circuits

I have a 3d printer (several) and am designing and printing a lot of the components to customize the controller. I am using openscad to design the parts.

The first component I designed was the mount for the breakout board

The next component I designed was the front panel mount for the on/off switches, pilot light, and emergency stop button. I am very happy with the way it turned out. It fits perfectly and for once I didn't need to print it many times to get it right. I can use screws in the drive bay to mount it in place. Everything lined up perfectly.

I wanted to protect the fan on the top of the case from swarf and other debris so I designed and printed this fan cover.

I've mounted the stepper drivers so they will get good cooling.

[ShuffleSk8ter]

you got yours first!


looking good....I just wish someone would make an economical kit for mounting the motors.....its just to costly for me....

looks good xnaron, is that a reprap printer? it does a very neat job.

Thanks...yes they are Prusa's that I've modified it to my own specs.

Looks good! I like the detail going on here. I too just purchased a G0704. Who is Billy if I may ask? I would like to check his parts out.

thanks...search "g0704" on ebay. His parts should come up if he has any for sale.

I think I will be following in much of your footsteps here. Less time setting up, more time playing with the final product

More progress on the controller. Contactor wired up along with xlr connectors for the steppers. I designed a custom plate for the AC plug and the xlr connectors. I am leaving one spot for another stepper connector. I need to go pick up another xlr connector to plug the hole. I wasn't going to bother with the xlr connectors but I got them cheap enough to make it worthwhile doing and they make for a clean install. I have space for another stepper driver as well. I also made an extension for the c35 parallel port to attach to the outside of the case.

I need to wire the power for the steppers and the bob and fans. I am contemplating doing a custom pcb for power distribution.

Personally I like to keep push button placement a little closer to the machine, especially the E-Stop. On the other hand it does look good! I haven't gotten into 3D printing yet, at least in this case the idea is extendable to other methods including casting.

A question if you will, do you have more info on that power supply? You mentioned 50 volts so I'm assuming it is not a PC power supply.

As to the PC what logic board are you using and for that matter what CNC software?

Sorry for all the questions I'm kinda hoping I can get one of these mills next year and possibly CNC it relatively quickly. I might go a bit larger though hard to say, I have to get it in the cellar you know 😉

dang, you need to make me some of those pieces lol. i like that extension for the parallel port.

[lcvette]

That looks awesome man! keep up the great work!

Nice work so far . I am deffinatley going to look into the fleabay kit . Even though im a machinist I just dont have the desire to make the conversion parts myself . Gota get my electronics into a box for my LMS sx2 so I can sell it and get a G0704 . I might even run it some manually before conversion . I will look forward to being able to hog on aluminum and cut steel . I would like to be able to make molds for various fishing stuff .

Keep up the good work . I will be following your progress .

What are you making all your mounts and plates out of ? Looks like wood laminated with glass or something .

That isn't the estop for mach...that is the estop for cutting ac power to the power supply. I'll put a logical estop on the machine.

The power supply is a 50v 600watt from antek. It has 12v and 5v supply boards on it as well. The bob is a c35.

I'm sure we can work something out

I'm using a 3d printer to make the components for the controller...details earlier in the thread.

Generally an E-Stop should kill everything that can be driven on the machine. I realize this isn't an OSHA compliant machine but consistent behaviors in E-Stops is something everybody should strive for. An E-Stop that doesn't kill the machine does little good.

The power supply is a 50v 600watt from antek. It has 12v and 5v supply boards on it as well. The bob is a c35.

It is great watching your build come together. I hope we will all be seeing parts off this machine soon.
