Awc 608 Problems

[Tech_Marco]

How fast do you need to engrave? Can you send me your test file and I'll sent it to my tech for testing.
What is your setting on the stepping motor? 1/16, or 1/32? Also, what is the "um"?

Dear Mr. Marco

As you know i am working on the High Speed Engraving machine. I am facing problem is that when our design ( job ) width is thin like later, straight line, etc..

then our machine can not engraving that same. for more information please check attached photos.

Hi Djsuthar,

I need to correct what I wrote after checking your result-picture.
Your problem is really a delayed laser-output.
The question is why?
Arre you using Diamond-Series from Coherent?
What is the PWM-frequency setting in your laser controller? What is letter-size of smallest line on your picture?
Is the result the same if you engrave on anodized aluminum or clear acrylics?

200mm/s is absolutely not "high-speed" - not for the cheapest laser-tube, absolutely not for a Coherent-RF-tube and also not for your Leetro controller.
It can be possible that your problem comes from using long and unshielded cables between controller and laser tube. (just an idea)

You're a western people and you don't understand the culture of Chinese. Things may not be possible happening in Germany but it can be seems 'normal' in China.

Sorry for refreshing this, but to swallow this crap makes me sick.
Dear Marco, I lived and worked about 5 years in China I know the 三十六計 (Thirty-Six Stratagems) very well, I had lots of business-fights in big and small business and worked together with simple minded and studied Chinese people from Manzhouli (at the North Russian border) down to Shenzhen.
There is nothing strange in China, except some crazy laws and rules, made from f... politicians while representing the industry...but isn't it the same in the USA or Europe?
So what are you going to tell me about "not understanding Chinese Culture"?! They are human ...nothing else. Yes, business is different from what we know from western countries, but that does not mean that only asians are able to understand this.
Maybe you have some background because of your Genes, my background is the growing up in a socialism system and always trying out before I judge.

Please don't tell that kind of story to the people man!

By the way, I worked about 1 1/2 years in the USA & Canada ...your culture is not less strange than the Chinese to me.

What do you want to proof here? Honestly speaking, I'm losing my patience with you. If mine is crap than your's was a trash. To the some point I was trying to stop it and not boring you guys but you seems enjoyed doing so. Listen, you don't now the true behind it so please don't make the jugement on me. Being hurted by somoeone who're stealing your business and being imitated and telling out the true is a crime?? If you're not happy with me or my services or my 'story', you have the right not to read it and not answere. But the way you said is more personal attacking.

I thank you for your support to some question of my customers, but if you're keeping insulting me and being arroagant, sorry I have to block your account and from posting there. I don't use PM as I want to let all knnow that I dare to speak the true. And to be fair, I'll remove all "our converstion" after a while and the true stand still.

Here I apologize to other customers to hear my 'crap' story. Sorry for my 2nd grade English not being able to write a bettery story. I believe a true story don't need to be fancy English to make it up and will tell the true.

Walt:

I'm OK. I've nothing to do wrong in this case. If people don't want to know the true (or not willing to believe), so be it. I have nothing to lose anyway. I won't force anyone to believe me by pointing a gun to their head and say "Listen, believe on me or you die!" or "Use my DSP or I kill you"

One day I'll make my own DSP controller. That's my dream and that's my destination. I'm looking forward to.

Anyway, Walt thank you for your support. Really appreciated!

Dear Mr. Marco

sorry for delay in reply.

1.I have set 5000 micro step from Kinco Company stepper driver.
2. I have select 25000Khz freq. in Laser cut 5.3 software.
3. i want to make our engraving machine 65 inch/sec.
4. yes i am using dimond serial of laser tube from coherent.
5. i have use shield cable in our machine. i am using RJ 45 cable for on/off laser tube and power supply details is this ---output 45 to 50 VDC, 12 A
6. i want to engrave 1mm small later in the our machine.

Waiting for reply

[Tech_Marco]

Reaching 65"/s (or 1650mm/s) is pretty tough for belt driven machine. To what I heard from many manufacturer it seems that an average of 750mm for cutting and engraving is the limit. Of course you can do straight line for over 1000mm/s. But for cutting and engraving, it's seem not possible. Note, it's not DSP card issue but the mechanical limitation. Don't forgot that the at such high speed the momentum it created is huge.

You may want to get a DSP to try it yourself as there is no way I can test it. Even with my new arrival XY stage, I could get up to 1100mm/s before it was losing steps.

Mr. Marco

Actually, i am working on two type of High Laser Engraving machine. 1. machine is stepper motor systems. and 2. BLDC motor systems.

And now i can move our machine on 1650mm/sec with BLDC motor systems and our mechanism and i can run 1000mm/sec our stepper systems.

I mean i can move machine on this speed , but when i engraving later and photos on this speed then i can not see laser fire image on the material. i think our tube can not on-off on this speed.

So, i need solution for this.

[Tech_Marco]

It may not be the issue of a laser tube or the controller you have, but the power supply. You got to know that a CO2 power supply need two inputs to work: TTL for enable/disable (or for PPI)frequency. The PWM for power control. Both of these two input are controlled by a frequency in between 20KHz to 100KHz.

FYI, different laser tube has different triggering voltage and operating voltage so if you swapped a laser tube even with the same power rating but by different brand, it may not work well if triggering voltage and operating voltage are different. For example, a 80W power supply work for Reci tube may not for other brand 80W as they have different voltages requirement.

From what you're saying, I think it's power supply compability issue. I wish I have your system to test. It sounds challegning to fix it.


Marco

[djsuthar]

Dear Marco

Here, i have given details of power supply which we are using for coherent laser tube.

Please check the below details for the 48 volt DC,
input power 100 / 120 48 vdc 14.6 amp
220 / 240 48 vdc 16.5 amp
Input Power 48VDC ±2% regulation, <±1% P-P noise/ripple, 12A max. avg.,
with 18A peak for 1 msec. minimum, measured at input terminals


let me know is it ok ?

[Tech_Marco]

I just talked to Pro sales in China. He said that you tube should run very fast! It's a RF tube, right?
He said that the issue should be the DSP on your machine. And he also said that AWC608 should run it OK but you need to change frequency to 5,000HZ

I don't know too much about a RF tube or the Coherent laser tube. I rely on info provided by other folks


Marco

[djsuthar]

Dear Mr. Marco

Please let me know following details . and yes we are using RF tube.

1.who is Pro sales in china ?
2. who is folks.?
3. who is real manufacture of AWC 608 control card.?
4. If any other person know about RF tube and high engraving, then please provide his details. so i can talk with them.

Waiting....

Dear Mr. Marco

Regarding my last conversation i don't know what you are thinking and what about others.

I know only i am engineer and i am working as a R & D Manager in the my company. - And i want to develop High speed engraving machine with High speed.

For this i need helps, In your last conversation you have told me you don't know more about RF tube that why i asked you any body can help me then good.

Second point is - i want to purchase AWC 608 card, for that my boss mailed you but you also didn't get perfect reply to him. thats why i want to know if you are dealer or manufacturer.

Any way if you can support to me then good. Hope you will understand this....

[Tech_Marco]

Hello djsuthar:

I hope you understand that I'm not the designer of the board nor am I the programmer. I don't know the limit of the card and I never use RF laser tube in super fast engraving system. I wish I can tell you the answer but I can't. As I told you before, you can buy a system for testing and if you're not happy with that, you can send it back refund. The only thing to cost you is the shipping. If you're not willing to pay for the shipping for your development, I really have no other solution for you. There is always cost for developing new products.

All I can tell you is that the AWC can run at 2000mm/s if "um" is setting to 15 or above or perfectly over 20. This is the answer I got from the programmer. Beside controller card, the frequency response on a DC power supply to the RF is important as well. So, without a 'real' card to test, I really don't know how far you can go.

The "other folks" I was refeering to person who worked for me and the programmer. Unless you understand flurent Mandarine (Chinese language), otherwise you're wasting time to get info from them. Plus, the answer you may get from shouldn't be too much to the answer I told you.

Marco
