73,7 volts measured in condensater
1.Is this voltage level supported by allin1dc?

2.Should I keep the condensater, rectifier bridge and board of the old system?

3. After taking a look at the installation manual, I think that the only question where I may have problems installing the system is in choosing the current limits of the motors since I have little information.
What do you think about this?

Sorry to be boring with this theme but i wanted to make sure i can install the centroid system and get good results with it, before i buy it

Thanks

73VDC is about what you would expect, if the AC input (from the transformer) is 52VAC.

You could keep your transformer, bridge rectifier, and capacitor/condensor, and use them with the AllinDC.

Note that your measurement technique above only works if one side of the capacitor is connected to chassis ground. That is true in some systems, and not true in others. To make a reliable measurement, you have to touch both test leads to points in the circuit itself (e.g. to the plus and minus terminals of the bridge rectifier or capacitor).

I think I would get rid of that capacitor assembly and just by Centroid's Capacitor Bridge Combo.
A little more than half way down the page:
https://www.centroidcnc.com/centroid_di ... nents.html

From the pictures it looks like the capacitor is soldered to that circuit board on top of it.
You could salvage it if you really wanted to....use Centroid's and it will mount horizontally under the All in One DC saving a bit of back panel space.

New here but have a nearly identical mill. Did @rui26 get this running?
