RE: [CAD_CAM_EDM_DRO] Re: Best way to mount Gecko modules ?

Baah! Nuk Reactor. LOL!
Good info though. Tells me what sort of heat generation I should expect to
see. I want to be able to install it and forget about it though. So
unless I get Fans w/ Alarm Lines I better oversize it then.
I pretty much figured from comments left here about vibration I'll
probably build an external floor or wall mount box.
Two remaining questions I have for you and the group:

Do the Gecko's need to be isolated electrically when mounted to the heatsink?

Les had mentioned in an earlier message about using 220v instead of 110v
for more stability in the higher current ranges. With all three of Les's
Motors moving at one time I can see the total current draw being pretty
high at times. So, would it be advisable to go that direction, or survive
in the 110v range??? (pun intended)

Thanks for any info on these!
