If you're going that route, silica gel crystals is the 'proper' stuff, as used in power transformer breathers.

RICE is your friend ! for electrical components you will be amazed how the stuff just sucks the moisture out ....

however ive only used it on smaller stuff, phones etc ... not sure how a...

We used to dry them out in an oven for several days, not too hot obviously just enough to drive the moisture out. Make sure any surface dirt has been wiped away around terminals otherwise surface...

Hi all

after doing some nice work on my little CNC plasma table, I have now got a job which uses all of its travel capacity.

The steel is a bit bowed, probably max 4-5mm variation so not too...

I have heard rumours of people managing to cut steel paste mask stencils with 120 Watts but the surface had to be dulled down first. I have no idea about engraving stone. When I think "laser cutting...

I don't know much about lasers (have had a 900x600 60W machine for about 3 years now and have never managed to set it up!!!), but if converting a commercial cnc router I would have thought it best to...

The laser assembly could be mounted on the machine without any problems. This takes away the need for long flight tubes, beam paths and alignment issues.
What materials and thicknesses are you...

Here are some basic answers to get you started. You do not want to move the tube. CO2 laser tubes are large, fragile glass things and require inconvenient things like 25kV and water chiller pumps....

If you want UK laser chat with laser freaks who actually do this stuff, how about http://oplaser.co.uk/opsupport/

Well no one with any sense would go to the expense of buying a motion control card and running nasty cheap drives or Breakout board with them.! Equaly no one would buy servo's and run them with a...

I use the Russian PLCM-E3 from Zapp and yes I did have a small problem with it. The controller worked fine (I use a slaved axis)
Then I found a problem with a probing routine and only one motor...

I only know of one in Uk selling ESS and they are ripping people off so I'm not even going to mention them. If you want the Smooth stepper then I and others have bougth from Peter Homann in OZ as...

Sorry I haven't been on here for a while, been a tad busy of late.

The latest version of AutoLeveller is 0.8.2 and as of 0.8 you can log your probe points to a file then feed that log file back...

Ahh right, well I dont know about double the money you would more than likely get a more powerful tube and so on, you seem happy enough to give it a try, I know John S purchased one rather than build...

Gunk might be useful for the cleanup too ?

With regard to the voltage, you need to find out what voltage each component is rated at. The spindle motor and VFD will be the first to look at, the...

This is the best video I think showing how to repack a ball nut, it worked for me no problem. It also shows the idea magicniner mentions to keep the balls in.

Linearmotionbearings C7 Ballnut...

Those four bolt heads holding motor look like could be eccentric cams to me.? Those will be whats used for tensioning the belt if there are no other signs of tensioning.

That's looks virtually identical to our Morbidelli. I didn't realize that they are apparently the same company, or one is the parent company of the other.

I would think that you can push the head...

There must be a way to release tension from the belt first ?

What's stopping you just unbolting the motor? ..Clive

Is this any good to you George?

Hi All,
.
I have been having a play with DeskProto for the last couple of weeks, as I was getting frustrated with Vectric 2D and 3D's lack of features and some "unsafe" practises. So I thought I'd...

We tried something new that has been planned by us now for quite some time. Me and my son 3D spindle engraved a Laurel & Hardy height map greyscale with a 1/32" Ball End Mill with a 1/8" depth. We...

Using vector control (also known as, FOC - field oriented control) also gets rated torque to zero speed with synchronous motors. Servo motors are generally permanent magnet synchronous motors and...

A Vector drive will give full torque at zero speed, but with an asynchronous motor not a servo or stepper.
Have a read, look at the vector drive section....
