It's been a while since I began building my solsylva 25x37 (iirc) and I'm getting back to the controller now.
Here's what I've got:
Gecko G540
3 nema 23 motors from Keling - kl23h284-35-4b
computer w/ parallel
various switches for e-stop and home/limit
I'm in need of a power supply now and this is where I need some help.
- I'm thinking about getting the KL-350-48 power supply from Keling.
Since this is a power supply not just a transformer, I'm guessing it has the smoothing capacitors already integrated into the package?
Will I have problems with the generated current when decelerating? If so, what would I use to resolve that problem? A 48v power supply is pretty close to the 50v limit on the g540.
- If the Keling power supply isn't a good match - what is recommended? (I was about to buy a 35v transformer, a bridge rectifier, and a filter cap array from HubbardCNC. But I was so close to the rated limits of those items - getting 49vdc, with the hubbard board rated at 50v. Then I'm also right at the g540 limit and I wasn't sure about how the Hubbard board handles deceleration (is that back emf?) I decided not to go that route.)
- Does this Keling power supply have an alternate secondary which could be used to power relays for the spindle motor?
- I understand I should fuse my ac power into the power supply - what amp rating should I choose with this Keling power supply?
Thanks for any steering you can provide. I'm so close at this point it's making me itch. The router is nearly ready and once I've got a controller ready I can get it running and tuned.
