It may have resolvers instead of encoders on the axes.  I 
(Pico Systems) have a converter that converts the resolvers 
to look like standard encoders.  Several CHNCs have been 
converted with my Universal PWM Controller and PWM servo amps.

[Emc-users] Hardinge Conquest 42 Conversion

[Jeremy Jones]

Thinking about picking up a Conquest 42. The machine is supposedly in good
shape but the Fanuc OT control might be shot and the motherboard would need
to replaced. Will try to resurrect but I'm thinking linuxcnc anyway since I
did a Bridgport recently.

I've seen a lot of CHNC conversions but couldn't find any Conquests.
Wondering if anyone has done one and if its similar to the CHNC's. I know
the CHNC II has the same spindle but I unsure of the remaining electronics.
Just trying to get an idea of everything I would need to replace to make it
work. It also has a 10 tool turret tool changer and I'm wondering how hard
that would be to get to work with LCNC. Any help is appreciated.

Supposedly. I have a similar setup on the lathe, pulling to 5 volts 
because it all goes thru a cnc4pc C1G.  Has been zero trouble.

One of:

5i25_prob_rfx2.bit  5i25_prob_rfx2.xml

A fresh card works.

So now I am in search of a 10 foot length of 8 gauge equ flat ground 
strap, to tie the computer to the drive housing and on to the frame of 
the G0704 to see if I can absorb an ground loop spikes that may have 
blown the other card.

But in Weston, WV, they are fresh out of hens teeth...
So I expect its fleabay search time.  For a 25' roll of 6 or 8 gauge.  
Amazon had it, 1/4" wide, bought 2 25' rolls. S/B here Saturday.

Are the 5i25 inputs 5V tolerant?

What firmware do you have on 5i25?

A hot reboot made no difference.  I'll try a Powedown Reset next.  And I 
do still have a spare card I haven't managed to install in the toy mill, 
yet...

Re: [Emc-users] Turning digital outputs on G-code move without slowing down

[Robert Ellenberg]

It just means that for specific moves that involve ABC axes, the planner
will fall back to parabolic blends (i.e. 2.6-style blending). This means
that continuous contouring using the A axis will be slower than the
equivalent 3-axis path, if the program has a lot of short segments. In your
case, the only effect would be a slowdown at the "indexing" moves. The rest
of the XYZ-only moves will run normally.

[Emc-users] 5i25 miss-behaving

[Gene Heskett]

Greetings, I hope Peter is about;

I have smashed up the brass plate I use for tool length sensing, twice 
today, because the 5i25.0.gpio.003_in is not seeing a probe contact.

Worse yet, it seems to be intermittent, working well after the first such 
incident.  Changed tools, and went to calibrate the TLO for these new 
Chinese TTS tool holders, and smashed it again while descending 
at .7"/minute.

Checking with a DVM, the probe line has about 3.3 volts on it, and it 
goes to zero on the DVM when even a gentle contact is made, but  its not 
stopping the machine, and a halmeter is registering FALSE full time.

Checking the status in showconfig, it (gpio.003) is an input.  And I do 
not believe I have a separate pullup on the line, that card is AFAIK, 
doing that 3.3 volts.  Any pullups I would have installed would have 
been to the 5 volt rail.

I haven't rebooted the machine yet but will before I head out to go have 
a chat with my sawbones here in about an hour.

In the meantime, if you've any suggestions, I am all eyeballs to read 
them when I get back. :)

Cheers, Gene Heskett

It has linear moves in XZ plane with small indexing moves on A
inbetween. How does the new TP handle such code?
