Hello,

I cut the first chip this afternoon  Grin ... and I made a video ... but it will be for tomorrow ... it's 1:30 (AM) and I have not eaten yet Roll Eyes

The spindle is a Kress 1050W (5.000 / 25.000 rpm), the same as my previous machine.

Do you have to start the spindle motor manually, or is it under the computer control?

I like the fact that the Kress has a nicely machined round collar for mounting.  How do you do edge finding with this machine?

Hello,

Spindle and vacuum cleaner are controlled by the Gcode, they are plugged on the 2 blue sockets in rear of the box. It's just ON/OFF, no control for speed by Gcode.

Not sure that edge finding is the thing as I think  Roll Eyes   .... If it'is, Z has a probe (the cylinder on the front bar, at the left of emergency stop).

For the X and Y, I use the same think that I use on my milling machine, and I don't know the English name for this tool  Embarrassed

The problem with the Kress, it's very noisy  Shocked ... and collets are not standard, unable to use ER11 or ER16, it's Kress specific  Angry Angry

The English term is just "edge finder" or "wiggler".

I was wondering if a standard US one (mine are all 3/16" diameter) would fit in the collet.

I know that 3/32, 1/8 and 1/4 exists for Kress, same thing with SUHNER (same size as Kress for inch collet, but both as no 3/16" ...)

 Grin if I translate "wiggler" by Google, he say that is an UPS (saving power for computer)  Grin

...Back in the workshop, I must finish the PC stand for the CNC  Wink maybe some photo/video later ...

I mistyped the above post.  My USA wiggler diameters are 3/8, not 3/16.

Hello Ralf,

 Grin Grin Yes it's painful, but in real you can't switch off the sound ... and even with helmet it's very noisy  Cry water cooled spindle are more silent ? or it's the same ? )

Maybe a box as yours for the future, but it's not the priority for now.

Hello,

I just noticed that I forgot to put the rest of the installation of the machine.

First I make ​​wedges to put the machine on it.









Then I make a stand for the PC

The raw material



plugging the hole on the bar with a steel washer made ​​with lathe.



Turning and milling parts used as rotation axis.



and welding at the end of the bar



making the rest of the support





and finished, naturaly, the wood parts GCode is created by Cambam  Smiley

a video of the machining

http://www.youtube.com/v/ZFLrd_YJw7o



installation of suction and Microlube









PC and Controler stand




Then I create a servant (not sure it's the correct term) with chipboard recovered from an old stereo cabinet, remains of floating floor and 2 racks purchased in supermarkets











I've problem with the 4th axis, It turn well in a direction and vibrate and lost steep in another (~10 in only one revolution) you can see (or rather hear) this on the following video. The 4th axis works well if I plug it on the Z output by example.

http://www.youtube.com/watch?v=jlLRb10aSis





And for now, I'm retrofitting an old drill-wise to use with the CNC, I have to reduce height and redo the jaws.

It look like Moon surface Grin













gain of 10.2 mm on the height
