I am not so sure that I am 'test'ing your driver. The currently runing 
image is from 2016-09-23-raspbian-jessie.img, which is a bit north of 
4.3GB when unpacked and written to the u-SD card by 

sudo dd if='2016-09-23-raspbian-jessie.img' bs=1M conv=fsync of=/dev/sdg
sudo sync

I had to add the spi modules to /etc/modules.

But the default user 1000 is pi, so I edited the u-sd card to nuke the 
user pi, substituting me as in the previous lite version.

And it just refused me perms to run synaptic, so this time I edited the x 
out of the string in passwd, then while root, put in a rather lengthy 
passwd I can remember, plus I put it inside the box with a p-touch 

But I finally think I found the source of a strong odor of burning 
electronics that seemed to be in the garage sunday, but I couldn't find 
anything emitting heat above 75F with an IR thermometer. The supply(s) 
for the x motor are now down about 5 volts from where I had set them, 
and the green led on the 2m542 x motor driver is very dim, but it does 
not further drop the voltage when I plug the drivers power plug from the 
supply back in. Sitting in the box while I did battle with SBC's, only 
the x driver had a signal, and neither had a motor connected in months, 
so just sitting there doing zip. I've NDI which has upchucked, but I 
just bought 2 more supplies, each able to do the job by itself, and 2 
more M542-T, very similar to the DM542's I've been useing forever 
without a failure in 6 or 7 years.  That, if its bad, was the 7nth out 
of my original order. So at this point I am out of business driving the 
x motor till they sail their junk across the big pond. But I can go 
ahead and get the Z motor wired up and moving, and the encoder hooked 
up, and spin the spindle, maybe get some home switches rigged, and maybe 
even some limits. Right limit for Z might be two switches, one on the 
saddle so it won't bang on the tailstock, and one on the bed for when 
the tailstock is off. And since we're into 40F weather, I believe I'll 
see about pushing it into the garage another foot because once the 
controller box is mounted, I don't have room enough between the closed 
door and the box to work in it.  I would have built an even bigger 
garage when I built this one back in 2008, but I was out of real estate 
to the west. Sigh...

Skin cancer? They've already used a sharp backhoe on my face 3 times in 
the last 15 years. I am pretty white, and have burned easily all my life 
so I'm not too surprised. At 82 yo, some things do tend to fall 
apart. :)
