Hello guys,
I'm finishing the final simulations and tests before mouting the new

Everything is working as expected except one thing I just noticed trying to

Pretty nice job Sam. I'm testing something similar while I'm finishing to
configure the machine I plan to intall in a few days on the Mazak. My goal
is to turn low lift camshafts (6.5 mm maximum for now, although 9 mm
shouldn't be a problem if the tool has enough relief).
Here's a video of a test
By the way, I'm feeding the field power of the 7i70 with the same power
supply that's running the PC. Could that be the problem? I did this because
it was the quickest way to test the boards.

Hello Andrew,
I'm finishing some parts of the enclosure for the PC on the retrofitting
we're doing to our lathe. I'm planning to do the same thing you want to do.
Using step mode and being able to home with index. I recall reading on the
forum a post from Andy telling that it's more than possible
I don't know if he was trolling or not but...
I will only say that I'm more than thankful that we still have communities
like this one and software like LinuxCNC.
And I don't want to be a flatterer or sound too political but if the
ideology seen here would be applied in more places and
Merry Christmas to all.
And I hope you feel even better Gene! My father almost had to had a similar
intervention but for now he doesn't need it. He's 80 and fortunately he's
working with us every day.

I'm about to connect a 7i71 I bought a year ago to the 7i44 (wich is

the field power on the 7i71 to avoid voltage to scalate too quickly.
My question is: is there any recommended

I'm building a CNC router for wood machining for a friend of mine and the
best way I found to drive the Y joint for this particular design, given the
size of the machine, is the following:
One rack and pinion on each side of the longitudinal axis of the machine
and each pinion
in the process of
forging, we only machined and heat treated the camshafts but the forging
process was made by another company.

Hello to all.
I'm trying to figure out wich is the best material for making cold formed
bolts wich need to have 25 HRc of maximum hardness.
I was thinking about using 1022 steel wich is suitable for cold forging but
I'm afraid the hardness process will be much more complicated than just

Hello to all.
I'm trying to figure out how to design the simplest possible wire feeder
like the one on this video: https://youtu.be/_pjbwFM1LM4?t=28s
As you can see the wire comes to a stop (a simple bolt with a nut) so I
suppose the feeding mechanism has some sort of slipping capability once
frequency allowed
and also to accommodate the scrap iron for melting. The machine also uses a
water cooled capacitor that has no label on it telling me anything about
it, but I guess that the capacitance could be determined easily.

Hello guys,
As you know, it has been like 4 year since we've retrofitted our induction
hardening machine for camshafts with LinuxCNC.
I would like to start melting some iron and I think this is one of the best
places to ask for advice.
The heater itself can lock onto frequencies between 10 Khz

I've always been curious about these grinding wheels. Are these dressed
like normal aluminum oxide wheels? Because sometime ago I read about
grinding machines prepared for CBN wheels.
The Landis ones I know have wheel dressers for CBN and the only difference
I really noticed is that the dresser
and
lenght of an entire camshaft.
So the idea was to find something more handy to do the testing.

I came across this leeb harness tester on Ebay and I would like to know if
anyone on the list has had any experience with such a device. The links for
the listing and description are the following:

Delta ones are a very good product.
Thanks as always!

a short time. Cooling is not going to be a problem at least in the
safety section.

hought about using a vacuum pump to suck all the oil
inside the tubing before making the switch between molds. I'm not saying is
the best solution but a possible one.

possibility to heat could be
induction heating but I think it's going to be complex aswell to make it
work because of the size of the molds.
Cooling is not a problem the way I see it, the problem is mostly combine
the two
I came with this approach, wich I'm now only evaluating.

cussing here it's going to be a
lot better than using water.
I've been reading that Dowtherm can last for 10 years without replacing it
so it sounds pretty convenient. I should look if there's a distributor near
me so I can call it.

worries me. I'm used to
handle 2000 psi on hydraulic systems but never above 50°C so it's not as
dangerous.
The problem is, since I'm going to have a long injection time I really need
to heat and cool the mold because it's the only way this project is doable.
By the way, I'm from Argenti
material combination's heat/cool cycle.
