DIY PSU build query...

[JAZZCNC]

That's the $64000 question isn't it.

I built a 70v PSU which means if I change my drivers they would have to be in that range or I need a new transformer.

I think mine is 1kva so I think I could run pretty much anything in the Nema23 profile on all 3 axis (4 motors) without blinking.

First let me say I'm not having a go at you or anyone with this post, it's just to make my point.!

Posts like these are what confuse folks and lead them to add up the wrong numbers. The Va rating won't kill your drives but choosing the wrong Voltage will fry them in a heartbeat.

Likewise, some of the other posts that are overly technical and made by people who know electricity don't always help either and add to the confusion because they talk in technical jargon that the person seeking information doesn't understand, or really needs to know to build a PSU suitable for CNC.

Sometimes I just wish those posting would take into consideration the knowledge level of the person seeking help and answer accordingly, in ways that don't blow people's minds. Or at least try to find the persons knowledge level and then explain in such ways that explain the technical jargon.

We all try to help with the best of intentions, which is great, but I do think that often the more technical minded could answer in simpler ways. This is why often some of my posts can bang on a bit because I'm always trying to answer in the simplest ways possible mindful that for every 1 person asking the questions there will be 10+ silently watching who say nothing. It's these people who often fall foul of misunderstandings because we can't know there knowledge level and answer accordingly.
Yes it's there fault not ours, they should speak up, but we can keep the jargon to a minimum, or at least explain it clearly so there's no confusion.

So ASK is the message to all those reading who never speak up.! . . . . . But to all you clever bugger who know it all just keeps it simple please and the jargon down.
