well - bought a cheap renishaw probe knock off from ebay. Having fun
calibrating the machine. the ball screws seem to be a little off of
what it should be 3tpi. seems to be linear - just off. (we are talking
.00017" per inch)
Here we are calibrating the probe to a hole we bored.

Maybe uploading (and linking) to the emc2 wiki is appropriate?

well, this brings up an interesting question, what is the best way to share
these files? I assume I can't just attach them. What file sharing site do
you recommend?

Possibly, yes.
Not in G-code, it has no way to handle arrays with curves in well (it
might be possible with computed parameters, like
#[100 + #1] = [sin[#2]] which is valid, but it
Hello everybody,
My father, my brother and I have a little workshop and we make camshafts as
spare parts for the local market here in Argentina.
Given the situation in our country with the medium and little manufacturers
like us, it's almost impossible for us to adquire a CNC camshaft grinding
ma
It doesn't matter, the wheel diameter is going to change in time due to use so
it will effect the final part dims, this is why cam grinding requires multiple
passes [one reason].
I've seen machine tools that use lasers to measure wear on end mills and such,
I suppose that is possible w/ a ston
Yes, when I looked a little further it appears when you purchase the cam
grinding system you get a code which gives you access to the software that
generates the G code.

You could use a separate software package to generate the G code, but I will
bet you c
The cam grinders I have seen dive straight into the cam face as the
camshaft turns. Flat tappet cams are tapered from side to side so
the tappet rotates as the camshaft turns to distribute the wear on the
tappet.Roller camshafts are straight across.
The guy I am talking to wants to move
The guy who contacted me tried to contact Sherline and I was told he was
unsuccessful in getting access to the software. Perhaps it is only
sold with the Cam grinding package which might make sense.

The wheel has a different diameter to the cam follower, so is tangent
to the work at a different point.
So, first you calculate the cam profile from lift and angle and
My understanding was that grinding doesn't require wheel diameter
correction because the precision grinding happens on one side of the
wheel:

Don't forget that whatever type of home switch you use,
it must be able to distinguish one (ball?)screw turn
from the next, and be reliable and repeatable, lest
disaster occur.
For those with homebuilt machines using fine-pitch
"All-Thread" screws instead of ballscrews or acme screws,
this can be

Sherline sells a miniature version of what you are talking about, and since
they sell their CNC machines with EMC installed it's probably done with that.
There's a picture here:

No, but I would expect the wheel to follower radius differences to be
handled by the cam CAM.

Guys,
I know a guy who is interested in using EMC2 to control a cam grinding
operation - as in automotive type camshafts cam lobe grinding.
Usually a large diameter grinding wheel is moved in and out to grind the
cam profile. Compensation for the wheel diameter is required.
Has anyone ever
Hi all,
Sliptonic posted this tutorial on a single HeeksCAD feature.
Apparently HeeksCAD can show at least one moving part!
(Although you have to create a "group" of at least two
parts to do this, so there might have to be a "phony" part
involved.) Anyway, it's pretty cool.
I asked sliptonic if I
