Updating to latest version of 2.8

Yes, I'm running @ 48vdc, but as yet have no way to measure current draw. That's in the works. I notice that the article that MESA has up indicates a substantial decrease in case temp with just an external fan. That's probably my next step. And, I think I have a couple of old CPU heat sinks around somewhere that may get repurposed, although MESA didn't seem to find a lot of benefit there.

Thanks, again, for the help!

NP,

I wouldn't worry about the heat that much. Put a fan, and/or heatsink and leave it at that.

I had my stepper machine on for about 8 months and never turned it off. They only get to really hot, but not more.....

get to making chips, or uuugh sawdust or whatever it is your creating.

True to your advice, I ran a couple of 45 min.tests today with a repurposed computer fan ~6" from the back of the G540. The results paralleled the ones Mesa has posted for their heatsink experiment. The high temp on the back of the unit never went above 49 deg. C. for either test. I'd terminated the same two tests a couple of days ago inside of 20 min. when case back temps exceeded 65 deg. C.

The only caveat is that I wasn't actually cutting anything. It will be interesting to see if things change when I do.

Thanks again to all for the great help!

Leonard.

Any indication of when v2.8 actually goes stable? Or, have I just had my head in the sand and missed it?

My master/pre-release of late June appears to be working just fine.

Thanks!

No. I was expecting it to be last Christmas!

But it depends on the Release Manager.

I cannot get updated to 2.8 or 2.9 because I can't seem to get past this point. Is this a command that I enter in the terminal?

You can edit the repositories in Synaptic, if you prefer.
Something like "settings / software sources / other software" I think.
