Yeah, horribly expensive. We do most of our shopping in France for the lower prices. I get paid less than the Swiss minimum wage, but my employer pays for my housing, so I'm able to survive with wife and toddler.
I still haven't been able to get my M3 up and running -- though I haven't devoted a lot of time to it -- since our discussion last month. I put LinuxCNC on a thumb drive and was able to boot it, but I don't have the setup files on it and the Linux won't connect to my wired internet for some reason.

Yeah...
Did some work in Switzerland many years ago. I almost died on the spot when presented with the bill for a pizza downtown. Is it still dramatically expensive there?
Funny when you write it. I havent seen anything about work in Switzerland. The only thing so far is in Graetz for NXP...

I copied them from my desktop computer, not from thr rteal setup.
If not, I can make a copy of my working USB stick. I just have to go out to the
garage and use the working USB stick as the original.

And it was probably best so as I can't make a bootale usb stick out of it now.
I might getting a bit senile but I can't for my life figure out ( remember that
is :( ) how to copy an USB bootable flash stick to an .iso file that can be used
top make a new bootable usb stick.
Most of the stuff from Google is microsoft and I simple don't have any of that
in my computers anymore.
Anyone with a recipe on how to do this in Linux?

You can use dd for this. In the example commands below, I'm assuming your USB
device is recognized by the system as /dev/sdX with X being the next available
drive letter. You can check this with 'df -h' as long as there is a filesystem
already on the usb drive. Do *not* use the partition number after the sdX, i.e.
sdd1, since the 1 refers to the 1st partition. The boot image has to be the
entire drive.
To make an image from your existing USB setup and write it to the file
usb-image.iso:
sudo dd if=/dev/sdX of=usb-image.iso
To go the other way, just reverse the if (input file) and of (output file).

Hmm, I just did a dd from a 8gb usb drive to a 16gb and it worked. All the
files from the 8gb are there on the 16gb, but, of course, only the 8gb
filesystem is visible. The rest of the drive isn't except in fdisk where the
remainder is unallocated.
I also have recently taken a 2gb iso boot image for my raspberry pi and placed
it onto a 16gb sd card with dd. Then used gparted to grow the filesystem to the
full 16gb. Booted just fine.

I'm starting to get rather fed up with the Foredom spindle now, not to mention
the Jacobs chuck I have. A lot of ther really nifty bits I want is min 8mm and
the collets I have for the Foredom is only max 6.5mm.
Also, I had to make my own collets as the Foredom collets only comes in 3 sizes,
all imperial. I now have two kits ofcollets, one imperial and one metric.
It actually makes a difference on the runout if I use 6mm bits in a 1/4" collet.
I'm now designing two new spindles. One with ER11 and one with ER16 collet
chucks. I'm making bosth spindles able to use a brushless DC motor as well as
the original flex wire. I'm still not entirely sure I'm happy with the ER16
because of the larger shaft size but I can always make the spindle in two parts
to accommodate for the wider areas around the bearings.
I'm watching a couple of lathe's on Ebay and I'll buy one this weekend.
I have a 1/4 hp DC motor but I think I'll go for a 1/2 hp one instead to get a
little bit more omph.
I intend to design the spindles to fit in the M3 tool holder, a diametre of 0.9"
or 1".
Dan, the foredom really just needs upgraded bearings. Use the one with the collets, if you have/made them already.

I have new bearings but I still get to much runout.
The collets I can buy are all imperial and comes in only 3 or 4 sizes.
I made two sets of collets so I have a full range of metrics as well.
The new generation of bits from Europe and Japan doesn't come in imperials and
the US lags when it comes to bits for exoptic materials. Besides, 99% of clients
outside the US demands metrics only...
Also, I need 8mm. 6mm shanks are not enough.
I'll buy a lathe during the weekend and I'll try decreasing some 8mm shanks to
8mm in the lathe to see how much accuracy I loose as well as how many tools I
kill.
The current design of the Foredom spindle use a way to simple front end bearing.
I'm looking towards a conical contact bearing if I can find one.
I use the best available SKF bearings, good for 44k rpm so I'm happy with the
perf of the bearings. Ceramic bearings doesn't work if I mill hard metal but is
brilliant for soft and composites.

Wow, what a coincidence. I am working right now as I speak (type) on replacing the spindle to the one I posted (Muscle MicRo) about two years ago on the lumenlab forum, but never put into action (router sitting in drawer all that time). I recently designed an aluminum piece that requires over 11 hours of roughing (not including finishing) using a 1/8" end mill at 15 ipm, 25% stepover and stepdown. If I use higher values, I get tool breakage. On youtube I watched a video of someone using a large machine removing more material than what I have in 15 minutes. Damn. So I decided to take the plunge and change the spindle. If is ends up breaking the micRo, so be it. Most of the things that I am trying to produce are just above the micRo's cabability or practicablility (15 min v.s. 11 hours )
I will post the drawing in my drawing file herein. I have already milled the 3 holder rings (parts 2,3,4) and modified an extra spindle block (part C) while I have the micRo still assembled. I have to take it apart to modify the spindle block (part A) on the micRo, which I will manually cut and plane out on a drill press with a 1/8" flat end mill.
I will provide a picture when the unit is installed and later, upon testing, I will inform you if it works well, or is the entire micRo breaks. Somehow, I am confident that the micRo is strong enough to at least improve time by 50%, remembering a video of Robin standing/riding on the micRo while it was moving. But we will see.

They did stand on a micro, but I can tell you right now that the micro just isn't rigid enough to get perfect facing results on most soft metals. I faced a 200x200 mm sheet of aluminum with a 1/2" router bit. Results were ok, but you can feel the tool marks pretty good.

I'm making a new concrete base not to far off in time and it's only coing to
cost be 10-20$ or so.
Ideally, a granite slab would be fine but it'way to expensive.
Even with a rigid base, you will get flex in the rods and blocks.
However,
If you add rpm control, the flex decreases dramatically if you use the correct
speed with defined by our tools. Feed and rpm is crucial for a good result. If I
control the speed accordingly, the milling bit cuts instead of grinds and
cutting develop far less forced in the "wrong" direction - with a "smooth as a
babies arse" result.
I'll try to cook up a decent recipe with pictures when I build my next concrete
base for my M3.

I just finished cutting and planing the spindle blocks (parts A and Con drawing) and just need to carefully drill holes and connect the router holding ring (parts 2,3,4 on drawing). Then I can assemble and start testing.
I do not expect perfection of milling since the micRo is only as rigid as the rods and hdpe blocks. The base can easily be stiffened with concrete, or the like, but everything else is what it is. The x and y axis forces are pretty much axial, but the z-screw is excentric from the y rod supports. Add to that the excentricity of the cutting tool, which will be greater with the router than the original spindle. So, that will also be what it is. The only way to improve that is to theoretically add a parallel y rod/block/stepper motor with the z block/spindle connected and placed between them, like a bridge crane.
The router does have some potential benefits: 16000-30000 rpm and 1 hp.

It helps by setting the speed and feed to what the tools require.
If your milling tools "cuts" instead of doing the high rpm "grinding", you'll
decrease the torque significantly. You willalso find the torque change
direction.
RPM= (metre/minute x 1000)/ PI x Diametre
So, doing the usual 25 IPM ( 0.63m / minute ) requires a RPM of
(63x1000)/(3.14x6). 630/0.1884 = 3500 RPM
Who feeds the mill 25 IPM at 3500 RPM?
Most users do the full speed, around 25k RPM. That would require a feed of
178 IPM for best result.
Seriously, these high speed spindle motors are pure BS except for engraving.
But please check my maths. The wife claims I can't do math properly... The
formula is correct however!

Your comment: "Who feeds the mill 25 IPM at 3500 RPM?" What does that mean?
Your comment: "Most users do the full speed, around 25k RPM. That would require a feed of
178 IPM for best result." What does 'most users' mean? People who do miniature carving, such as jewelers, use super fast spindles (100k) with very small stepover/stepdown (bite) values. An industrial millworker friend of mine has some very large mills that run around 3k rpm and when using large endmills (1", 2"), the feed rates aren't very fast either. Conversely, I observe on youtube all kinds of people using machines at different feed rates and bite rates, some very fast and aggressive.
Your comment: "Seriously, these high speed spindle motors are pure BS except for engraving." I have a product in patent pending that I used the micRo for creating test prototypes with parts almost 1" thick. That is cutting, not grinding nor engraving. So, if used right, the micRo can do more than just engraving.
I once contacted MSC, who provides customer service, and asked them the recommended feed rate for a particular end mill that I wanted to buy, expressing that I have frequent tool breakage. I gave them all the parameters and they calculated a 78 ipm. Their math was correct, matematically, but on the micRo anything over 20 ipm on alumimun frequently breaks the tool, especially during initial plunges at each new milling level where 100% of the endmill engages, even if it is for just a short run until stepover is possible. Conclusion from this: we need to adapt/adjust the theories to the micRo's capabilities.
By beefing up the spindle, I am trying to see if I can improve on time, by using a bigger end mill, say up to 1/4". Currently I am able to mill aluminum and brass, but it takes forever. Is anyone interested in seeing if a stong router works on the micRo? I am, because if it doesn't work, I will just have to save up big $$ and get a different system. But first, I will try.
It seems to me that most peole on this forum are interested in working on the electronics of micRo and/or creating pcb boards, that I assume only use 2d milling.
So, is there anyone in this forum that actually uses the micRo for 'traditional' milling or other applications where we can exchange experience with the actual use of the micRo that would be mutually beneficial?

Tsss
Don't break out the comment out of the context.
To use the mill bit as a cutter, you need to set a different speed/feed than we
usually use. Normally, we run the motor at max rpmand happily feed around the
spindle, more or less using the tool for grinding instead of cutting.
The BS part might stick out but when you talk with an old fashion engineer and
tell him you want 44k RPM - he tens to look at you with kinda blank face.
Running fiftyleven rpm is of course required if the spindle speed and power is
on the weak side.
The formulas to calculate best speed and feed for tools are normally given by
the tool manufacturer.
I byy most of my high end tools from www.cutweltools.co.uk and they are very
specific on the speeds.
As noted earlier, the micRO tend to give a surface with the typical runout
circles. Mostly because of flex but also a soft spindle.
However, testing with a lower RPM spindle and a 1/5 to 1 hp motor gives a
smoother result. The runout circles are there but in another direction and not
as deep as with the 1/4 hp flex shaft motor.
Also, the tool runs significantly cooler when it cuts according to the tool
speed/feed recommendation. And if it runs cooler, less unwantedforces ought to
be the result, and is inline with the smoother result.
But as ever, milling like we do with sometimes non-ideal setups is not a science
and the mileage may vary.
I also noted that my micRO's "original" power supply might be on the weak side.
If I run simultaneous ( or close to ) XYZ movements, the milling speed varies.
It can of course depend on the extra CPU load, having to calculate movements for
all axis. But I don't believe a 1.6 GHz CPU is to slow...

So, is there anyone in this forum that actually

beneficial?
Hi Mikau,
I agree that some of the formulas I have seen for calculating feed
rate/RPM don't seem to work well with the MicRo. For example, when
milling the holes in my base plate I had to use a much, much lower
feed rate than you would expect for a 4-flute EM turning at high
RPM. I think the limiting factor is the rigidity (or lack of
rigidity) in the MicRo itself, and especially the limited torque of
the spindle motor. Calling the MicRo a "milling machine" is like
calling the Vespa Ape a pickup truck... sure, it meets the
definition, but the MicRo is no closer in capability to a Haas or
Bridgeport than the Ape is to a Ford F250.
With a high torque, high horsepower motor turning a rigid shaft in a
solid machine you could use the maximum / optimal feed rates. With
a small fractional HP, high RPM motor and a flex shaft drive, trying
to do such a thing will very quickly stall the motor and break the
tool - and probably destroy the work piece as well.
Most of the milling I do is with ABS plastic. I've found that I get
the best results with a single flute end mill, low RPM an a moderate
feed rate of 12-30 IPS. For aluminum I need to use high RPM and a
low feed rate; in fact, when stepping down into a hole I usually use
about 2 IPM to avoid getting too much deflection. Putting a .203
hole through the base plate takes about 6-7 minutes per hole, using
a .125" 4-flute tool.
So what can be done about it? The flex shaft tool was designed for
grinding, engraving and wood carving -- not milling. The MicRo
really is not well suited for directly attaching a high torque
motor, except maybe a brushless DC motor. As much as I'd love to
switch to one of those, I'm going to have to wait for someone else
to come up with a good way to do it -- I've got my regular job, my
side business and a couple of other projects (like building an
airplane) that are eating up all of my time and then some. So for
the time being I'll stick with the flex shaft and all of its
disadvantages. It's certainly not perfect, but still gives me a lot
of capability I didn't have before.
I agree with everything that you said. I have made small holes in aluminum using 1/16" end mills running at 1 ipm and 10% bite. On the average, a 15 -20 ipm feed rate works OK for aluminum, but as I mentioned before, some projects take forever. So I am experimenting with the router even though I know the micRo is not built for it.
In the picture file, I placed a phone picture of the router clamp. The bottom and top of the router have vent holes, so I may need to create splash guards for those areas when I use coolant, that is, if I ever get to that point assuming the micRo does not break.
I am self employed and work by contract so I get chunks of free time between contracts to pursue other interests. So I try to create things. I have been looking at Tormach 770 "personal cnc" for a while, $10k with accessories, maybe I can save up for that. Or maybe Robin is working on an upgrade machine. I have also been looking at Sprutcam; seems better that the cam software that I have that does not have reroughing/restmilling unless I buy the 5 axis expensive version.
Hello Robin: I sort of heard that you were involved in an upgrade project??

The iso file is slowly coming your way. The download speed is absolutely
ridicolous and only around 700 MB so far. I started around your local time 7:46
and I still have 3+ GB to ftp.
But if everything holds up, the file should be txfered during the night.

 Somehow, I am confident that the micRo is strong enough to at least improve
time by 50%, remembering a video of Robin standing/riding on the micRo while it
was moving. Â But we will see.

Not yet... but I need to do some engraving, and so far nothing has
worked satisfactorily. I used a sharp engraving bit and a program
to probe the surface and adjust the depth accordingly. It works
"OK", but with an anodized aluminum surface the slightest tip defect
results in ruining the piece (an expensive $10 Al cabinet) during
probing. Not probing didn't work because the surface isn't flat,
and I don't want to go to a spring loaded diamond drag engraver
because I want to do some plastics as well.
So... I'm thinking about building a spring loaded spindle
attachment with a Delrin or Teflon ring to set the tool depth. That
will let me use whatever tool I want, and set it to whatever depth I
want, without having to worry about surface variations. The
applications are as diverse as lettering on Al sheet (aircraft
instrument panel), ABS plastic boxes and extruded Al cabinets.
Problem is... I've got too much other stuff going on, so
realistically I'll be dead before I get time to do it. This is
starting to look better: http://www.bullerent.com/Engraver.htm.
After all, I did manage to make the M3 pay for itself in a year!
I've been using autoprobing for a good while now. It's an absolute necessity for
pcb making and engraving. But it wasn't until I started using a vacuum tabler
that I achieved perfection.
Go get yourself a vacuum table!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Or build one. But talk to me first as I have some valid pointers...

Autoprobing works great -- IF you're
not working with an anodized surface, or a painted one. And a
vacuum table would be nice for flat sheet stock, but it's useless
for doing what I mainly need to do, which is extruded aluminum and
molded plastic cabinets. I'll do a few flat sheets, but I'll do
thousands of boxes.

Just saying . . . I had plenty of *mixed* results with upgrading bearings in
Foredom and Chinese spindles. For this to work for the general populace I feel
a very high level of detail must be provided in terms of precisely what bearings
to buy as well as an iron-clad protocol for actually changing out bearings. I
keep losing two cents everywhere.
