El Hefe Lives

Nice mod on the holder. I know you know this, but that holder isn't going to be real rigid. No hogging cuts! ;)

21 volts is a bit low. Is that with everything disconnected, i.e., no-load?
Yeah i know it wont be real rigid but the entire lathe isn't very rigid and i will only need to remove .020 max off the stock.
And 21 volts is directly off the pins on the vfd with no load from the panel. Same reading at the switch in the panel on line and load side, as well as the line side of both led lights.

Edit: I think I found the culprit. Im losing about 10% from the dc transformer, and I have a 10% imbalance in the 220, which is traced back to the line side of the meter so xcel energy needs a new transformer to feed the house. That's my theory anyway.

Most 24VDC LED indicator bulbs will work just fine on anything between 12-24+ volts AC or DC and draw about 11mA, that you have 21 VDC out of the VFD is puzzling, but the line voltage coming into the VFD would not affect this supply. The VFD is rated for 200-240VAC input. I would pull the light bulbs and see if you have LED bulbs and the voltage. Like Jim mentioned, it could be a 120V LED or incandescent bulb, sometimes returned switches to AD might get mixed up and sent out wrong. Also double check the 24VDC voltage supply from the VFD is 500mA, usually they are much less, although Danfoss says 200mA on some models. I would check the current draw if you have a mA DVM, or if there is a sag in voltage when the LED lights are on, they are normally quite bright.
 
I got the new quill stop mounted and re aligned the dro scale for the quill today. 2d4f85834e0e832f547e3e0129a7375f.jpg

I double checked the invoice that I ordered 24v led stuff. Its just weird that both led lights are dim. I could understand if one was 120v and one was 24v ( one bright one dim) However I have not pulled them to verify. I did check with my snap on dmm and there is no measurable change in voltage with the led lights on vs off. And no voltage drop through any of the switches.

Just to cover all the bases, I'd check the LEDs just to make sure. Because this is getting down right weird.

Nice finish on the quill stop. Still sorry I didn't get that finished before you took the mill. :(

I think i may just order 2 new 24v led lights from automation direct.
No worries about the quill stop. It was a good little project I enjoyed making.
