Does your rotary axis jog quickly but then when running jobs move much slower
than expected? If so this program may be able to help solve that problem!

My guess is there is a second WiFi network someplace. WEP password should
be enough.
But yes, whitelisting all you MAC address would be "bomb proof" on that
network. If there is another network it will not help.
People install all kinds o backdoors without knowing it with things like IP
WEP is useless. WEP was cracked in three minutes almost 20 years ago. Byt 2007
there were 1 minute or faster WEP cracks. WEP was replaced by WPA-PSK, which
was also eventually cracked. Then came WPA-PSK2. That took linger to find fast
cracks for but they exist now. Ine is called "hashcat" and
There are companies that regrind worn ball screws then stuff them with
oversized balls, at much lower cost than a whole new ballscrew. ISTR reading
some claims of making a rolled screw as precise as a new ground one since
they're precision grinding the old rolled surface.
Whether or not it's

You'd have to set it as an allowed list rather than a blocked list. Block one

No one can do that, not even government agencies. There is something else
going on. Perhaps there is another WiFi network open. You can set up
most routers to only "talk" to a white list of physical devices. Then he
does not even see your network. There is no way to guess a WEP

Updating to the latest 2.7 version should not take any effort, it
should be automatic (in fact I am surprised that it hasn't happened
automatically, it

Not recently. But external logins can't get admin rights on dd-wrt
He might be reading your password in the same way as you are setting it, namely
by logging into the router. Did you change default router admin password?

No,
Has anyone scrolled down the iink to check the reducers?
I'm not a stepper person but they might make a good start at a 4th axis. :-)

It's an interesting idea but I can't afford that level of potential
downtime currently. Getting the machine to where it's at has taken a long

Maybe over xmas break or something.
I'd be interested in any other internals

Gene,
I'm not familiar w/ the 3phase steppers, but usually stepper drivers have
dip switches or a dial to change the current to the motor. You'd want to
flip them in such a way to select a lower current, which in turn would
provide lower torque. This 3 phase stepper is probably an odd ball
I suspect that all of these Chinese drivers are actually the same. Likely
they are all Leadshine clones. The ones I buy from "Stepper Online" are
leadshine clones.
Go to the leadshine web site and fine the product you have. It may have a
different part number then click "downloads" and there

We couldn't live without wifi in our house, I should probably lock it down
a little better though.

Yes. As I recall it's mounted to the back of your monitor. I'll look into the

That seems strange. Which version of LinuxCNC are you using?
*AND* by not using the default WiFi router password.

I enjoy pointing out the smarts of Steve Gibson.
I've set up an Epson ET-2650 printer as a WIFI access point, and since
the interface for entering the password is so awful, I created a
password specifically
