Gene,
Once I get through this project, about a dozen parts to g-code and then
machine (the CAD work is done), I will consider upgrading. But as you
probably know very well from your own experience, I am invested in this
EMC2 version which is at the end of a string of software applications- CAD,
Chris,
Yes, the files are backed up, but since it is a boot drive I wanted to take
it to the next level of preparedness.

Hi guys
I have classic ladder up and working finally. sussed out how to use Halcmd

anyway I am using classic ladder now and am a bit stuck. Nothing too much
but I think I may have the wrong pin linked or similar.
You can pipe the output of "dd" through gzip and compress the disk image.
It will be many times smaller. But in this case, where the drive is
actually making nose, I would ASAP do a dd copy to another drive (an SSD)
and then put the new drive in service. Make a second backup copy later.

You most probably backup data, in Linux the "/home" folder including all
subdirectories. Not sure if it is possible to save a list of installed packages
in Linux.
CD-ROM is cheapest if there is enough space, DVD is larger and magnetic tape
provided you use modern tape drive is the largest.

Gentlemen,
tin happens to stand near to the transition metals in the periodic
system and thus tends to slowly turn from metallic (conductive) to
crystaline (noc-conductive) as time goes on. At room temperature this
takes very long, say 10 years or more, at low temperature faster,

Nope. Drive and motor and cables. The adaptor board converts the TTL step/dir
or pwm/dir into the appropriate signals. Step requires RS422 for high speed
step rates. Slower rates can be open collector type drivers. The PWM module I
picked up off aliexpress for about $10 which is how the

This is interesting, for two reasons:

The Gecko pins were not burnt, but I did burn a pin on a heavy duty 5 pin XLR

It was running the Knee with a 1200 oz-in motor and 60VDC power supply.
Typical result of a high-resistance connection getting hot.

The invoice for this drive is dated 07JUN2011. The drive was in use for most

And perhaps it needs to be further burnt to complete "ashes" ??

This is typical for poor connection in environment with mechanical
