Maybe you should check the cutting parameters especially the piercing distance. i believe it is set too low.

The supplied cutting distance and piercing distance should not be change as per...

If you know where you can bypass the thermostat, you can try this.

1. bypass the thermostat (so you can run the compressor without stopping)
2. run your laser
3. note the tempreture rise if it...

Hi oneeye,

What you have done is impressive but i hope you have properly earth the machine just in case the water came splashing out and come into contact with the HV terminals on the laser tube....

The steel are used to prevent damage to the bottom of the material.

Most large laser machine companies advise to use the same method to prevent damage on the workpiece. Some company advise to use...

Maybe you could find somebody to use a turret punch machine with rubber strippers to avoid scratching the mirror finish.

Turret punching is far cheaper to do your work as compare to laser cutting...

Basically the caloriemeter is calibrated to a 20 sec period. The actual period is normally marked at the back of the display - sometimes it is 20.1 and it can be 19.8 second.

To use a 100w meter...

Some extra notes on the reply by laser tech,

water out is normally on the output side (High voltage side / output coupler side)

Normally the water is supplied by a cheap fish tank pump as the...

To add a note,

This is a OEM supplier (for laser mirror and cutting lens) and of course you have to pay higher price for their products which is of a high quality.

Normally you would not have this problem too much on the y axis.

The encoder strips needs to be clean - use reagent alcohol to clean them with a soft lint free cloth.
Also the encoder and the...

Sorry to have you misunderstood what i have meant.

The tubing i refer to is the copper pipes and also the plastics pipes and not the Glass tubes on the resonator.

After some period of time the...

The HV probe as suggested by PaulC is a must for checking high voltage.

Please make sure you follow the instructions that come together with the probe - especially the earthing for the HV probe...

It is true, what you have said.

What i mean is that, there are some "members" which i think create stories about failure of their laser machine.

When you tried to help them, they are unable to...

I believe there is a service centre in the UK for bystronic.
If you fails to check the fault after many attempts it is better to call the service center.

Have you check all the laser gas tubing...

I was looking at the HX laser website and found their short movie is quite impressive even though their english is not as good as it should be.

The way they teach you how to set up their machine...

0.075" is approx 1.9mm stainless steel.

The cheapest way to cut is to use the plasma cutter.

An example, from an old cutting parameter for a 1200w CO2 laser the cutting speed is approx 3000mm...

Hi signbloke,

As far as i know it is true that the laser gas will degenerate over time.

If the output coupler gets darker, most probably it is from the fumes that attached to it while using -...

Hi signbloke,

360usd for your 80w tube is a good price for testing and experiment.

You are saying it last for about 4 months, basically how many hours it is "on" and is it a full 80w power all...

Since you are using almost full power all the time, it is advise to clean your cutting lens regularly.

Normally how's the lens fail? Is there dirt at the bottom of the lens or oil on the lens or...

The laser power depends on what you are cutting and also the cutting speed.

For paper cutting the power needed are lower than for metal.

A 4x4 price is not a big difference to a 4x8 since the...

There is a lot used punching machines around example armada, strippit/lvd, trumpf, finn power,

For 40k i think it is quite impossible to find a decent one except maybe a very old model.

Do not...

two cents of thought,

Do you cut the same material as the trumpf?

Is the power for both machine is the same? eg.4kw on lvd and 4kw on trumpf

If the material is the same and also the laser...

My two cents of opinion,

I think the adjustable Z axis is a better choice but the added weight might pose some problems.
On this method the four corners are perfect.

On the other hand, if you...

Actually i saw the method you use over the internet some years back.
They recomend to remove the i.c. chips this way.

I have to wish you good luck on the salvaged components and before you use it...

Hi mononeuron,

In my country i can make a choice from TT (telegraphic transfer), Demand draft and Payment order from any bank.

I believe you could have send him a cheque (demand draft as in my...

Hi mononeuron,

What type of money transfer are you using?

Normally i use TT (telegraphic transfer) or Western union.
TT for me is far cheaper than western union, that's at about one third the...

Basically you need to know the temperature range to be use (max and the min).

Then you will need to the different type of sensor based on the required temperature to be used with the controller.
...

Food for a thought....my 2 cents opinion

Now i saw some people are collecting only plastic bottles (eg. coca cola soft drink) and then recycle it in one factory.

These people only buy/collect...

For the cooling water you can can in bulk for example 5 litre bottle in the supermarket, in my country 5 litre distill drinking water cost below one US dollar.

Normally there is a choice between...

"Funny" in my post means you want something and you would not say what you need.

Okay i presume you are trying to copy the design.

Why can't the normal 2d software be used if the end product is...

The engraving lens is just above the workpiece and in my opion it best to order maybe another two piece.

The courier charges will cost more than the price of the len.

I have seen the difference...
