Hello Ihatecreatingnames:

I hope you understand that I was not upset at all. It may be my language issue so it may made you feel that I wasn't happy about your feedback. No! It's not. I always welcome feedback from my customer. I think you know that English isn't my native language but second language. If you talk to me by phone, you will understand me better. I sometimes replied very quick without going throw so call 'first draft', '2nd draft', and 'final' like what I was told in my English class. I was trying to reply most question as quick as possible so that my customer know that I care their question and feedback. So if my response offense you. Well, since you're an engineer like me, I think you understand my point and won't affect your faith on Marco ;)

Regarding the size issue, one thing I can sure is that if the size of the machine is defined, the workable area is guaranteed. Say the machine is 900x600, that means that the cutting or engraving area is 600x400 or a little bigger like 620x410 something like that. I think a customer won't complain if the workable is a little bigger than what they buy, will they? If a customer need perfect size of 600x400, can I order it? The answer is "Yes". In general, I don't want to give so many 'requirement' to tech in the factory as doing so may interfere their job or causing unnecessary mistake.

About the shipping, if a customer is not willing to do local pickup or if pick up cost is not justify, I'll ship the machine direct from the manufacture to them, door to door. In that case, I'll have my buddy Mr. Lau, who is an expert in CNC machine to do QC for me. His dad used to do tools and parts (oem) for SONY. He is good on MasterCam, ProSHop, G-code,AutoCad.... And now, he work for me as a consultant and he will inspect each machine before shipping. We know the issue of other US customer having a lot of trouble to get the machine to run bought from China. Once a machine shipped, there is not much both side can do anything to the machine. Tech support is an issue and shipping cost is another matter. So, to avoid this hassle from happening, I always tell my partner and other tech there to make sure the machine is fully functioning without a problem. It is not about hardware alone but cosmetic is also important. They know my standard is higher than local order so they usually pay more attention to the machine made for me. The boss there always shoot me pictures and video for review before packing.

Some folks always yelled "Chinese product cheap and no good". when receiving a product that doesn't work or having quality issue. Well, that is a very sensitive topic. I have to say "It depends where you buy it from" and "How much did you pay for". Remember that iPhone, HP, Sony, .... so many companies are having their products manufactured in China. Is Chinese product really that bad? I don't think so. When most company selling a machine for $6~7000 and you pay $4000 with S/H included. Then, you shouldn't be surprised when there is an issue. Of course, some may challenge me by making this conclusion but not considering a 'great deal'. Well, I'm not challenging anyone but it is quite against the odd. Here is what I learned from over 10 yrs dealing folks in China. To get good services from company in China, most or less a friendship or good relationship must be 'established' or you won't go too far. That's why I traveled China twice a year to see my supplier.

Let me wrap things up other than talking too much and you may get bored. If no one has special requirement on a machine they want to buy, I will use specification obtained from the manufacturer as the standard. But if anyone has special requirement like size, color, weight, shape, ............. just ask and I'm open to taking special order that is feasible. I will try my best to get you one to meet your requirement. If you want pink, I can have your machine painted in pink. If you want working area 1195 x 885mm, then I'll make one for you with exact dimension even though I don't get the point why not use full 1200x900. Or, If you want the power Z table one the 6040 machine change from 200mm instead of 150mm, we can make you one but you pay more on the shipping cost. Or, if you don't want operation voltage of AC220V, we can make AC110V. I'm trying to be flexible as much as I can. I am not the man can do this magic work but they do - my partner company in China!

Pink machine? Hmmmm.

I was a team lead engineer for large company that designed computer system on a chip ASICs for customers around the world. We also had design centers around the world. That included a design center in China and customers in China. I very much understand how difficult that communication problem is and wish you luck with it.

I don't want to change your machines. I just want to be sure what I am getting in certain areas. Most of it is fine. The web site confuses me here and there. One area is the shipping of machines and XY stages. Another is the large tolerance you spoke of on the work areas. +-30mm is over plus or minus an inch. That's huge range. Simple measurement on your part should clarify that. I told you why I was interested already -- small end of size range may waste material because it won't fit. I would have expected that to be a common problem for folks who buy standard engraveable supplies in US. So a little puzzled.

I have about decided to build my own machine out of your parts. Likely use 600x900 X-Y. Between these discussions, the words in the descriptions of the various sizes not looking consistent to me, and the choice of shipping cost you must make in the cart, I am not totally sure what the shipping cost will be at this point. I have no problem with you shipping stuff directly to me if that is significantly less expensive. But I am not sure of that either. Maybe I should submit the entire order and let you sort out the best way to do it?

I am wanting to cut puzzles, among other things. May be wood, acrylic, or cardstock backing in the range of 2 to 4 mm thick (I think). Want cut kerf as narrow as possible. I am considering 60W or 80W tube (want to cut some thicker acrylic too as well as some plain vanilla engraving) . I want a red laser with beam combiner, a beam expander (which one? and what focal length lens?), and was considering 35mm mirror parts you sell because of beam expander. That would waste bunch of parts on the XY stage unfortunately unless you have a solution for that. Will build or acquire a motorized lift table. Not sure the value of autofocus.

I also see that the XY stage says it has 3 phase stepper motors. What stepper driver works with that? I had considered using Gecko 203 drivers -- way overkill but indestructible. Not sure if they will work.

Picked a 10L per min pump. Not sure is big enough. I read your comments about appropriate temp for cooling water as well as Parallax site comments and RECI site comments. They are all in agreement there is an issue, but disagree on appropriate temps. RECI site has a much wider range specified than I expected. This is all very much an issue in central Texas where outdoor temps can be 105 F. That is too high a temp for your chillers, for instance. Not sure what to do other than put machine in an airconditioned space. My shop currently does not have that.

I want a conservative, bulletproof machine.

I probably build chassis out of unistrut and vibration isolate it from the XY stage, laser, and lift table if possible.

Your comments on the above would be appreciated to help me complete the BOM and order.

I read you. Since more than one is concerning the dimension issue. I'll fix my description. Regardless the +/- 30mm, it really has no affect to the "workable" area. The workable for sure will meet the size I specified but capable to make some adjustable. I guess I have to say "more but not less" ;)

The ocean shipment will arrive tomorrow 9:00am. We're ready for the new arrival. The demo room has been built. What I need to do is to fix some florescent light, add ventilation, and add power cord. I'll provide rental services for the local folks who isn't ready to buy a machine but need laser services.

I'll post the shipment pictures tomorrow and the demo room.

If you're going to buy large, bulky parts, it's best to submit the order directly to Marco so he can calculate the shipping better - the estimator on the store when I ordered my 1200x900 XY stages was out a fair bit.

Finally all machines arrived safely. I have put four new machines in the showroom and a older model for testing purpose. Currently, I'm waiting for air veneration system and power installed. All machine should be ready to run sometimes on next week.

I'm planning to do case in Kit set so that one could buy one to build a complete and big laser machine. My first try will be 600x400 and 900x600. Will use extrusion aluminum as the frame with precise cut and hole pre-drilled. What it need is the front panel but anyone can use the machine to do nice cutting on acrylic. For 600x400 machine, it should install a 60W tube and it is powerful enough to cut through 6mm at 5mm/s.

So, you can have yours big machine with different color (acrylic is colorful to pick) to select from.
