  1. Re: Omni 1530 ordered and ongoing log of the process

    Very, very bad experiences with Omni. Too many con games. Try Max at NewTopCNC on Alibaba. No reply needed.

    Re: Omni 1212 Delivery

    It sounds as though you are getting a basic machine with standard Chinese components. Mechanically the machine will run. If you must comply with local commercial safety standards, you will need to...

    Re: Dust exractor

    Omni take on contracts that they cannot fulfill properly. They cost me another $625 because of a local DDU shipping SNAFU. Promised control features were not included in the control panel and in the...
  4. Re: Omni 1530 ordered and ongoing log of the process

    I don't know how much this will help you, but there are grades of collet and collet nut. The basic level (supplied with mine) are 1 grade above lathe std and are not good for CNC. They are in...
  5. Re: Omni 1325 options - NC Studio vs DSP A11 controller, and other advice invited

    Victor, Again you have missed the subtleties of the points made in my last post. You muddy the waters with incorrect information and sound like a Chinese factory representative here to help the...
  6. Re: Omni 1325 options - NC Studio vs DSP A11 controller, and other advice invited

    Victor, It's clear to me that English is not your first language. There is nothing wrong with this, but your English comprehension is often a problem and your replies do not focus on the salient...
  7. Re: Omni 1325 options - NC Studio vs DSP A11 controller, and other advice invited

    Victor, In the case of my machine, it was never about late arrival at the destination because of shipping problems. One of my contacts here in Canada from whom I bought a refitted laser cutter has to...
  8. Re: Omni 1325 options - NC Studio vs DSP A11 controller, and other advice invited

    Brian, be very careful with these guys. See my posts in this forum. Make sure that EVERYTHING that you want in your machine configuration is in the contract. They are losing repeat business according...
  9. Wiring schematics and user/maintenance/tech manual not provided.

    I emailed the message below to Sunny Sun at Omni a couple of days ago and have had no response from him or Zach Sun. This Omni 1325 CNC router took 2 years to build and there were many games on his...
  10. Re: Omni 1530 ordered and ongoing log of the process

    I'm not trying to insult you. The inspection of the building and the equipment are 2 separate issues. You are probably right about the space heaters too. It is possible to use the machines without...
  11. Re: Omni 1530 ordered and ongoing log of the process

    8mm steel, you may get 6mm for a lot of it. My inspection showed this by micrometer. Also, I have read that not all of the seams joining the legs and the table are welded.
  12. Re: Omni 1530 ordered and ongoing log of the process

    You're a bit behind the news. The UL & CSA settled this issue in court 4-5 years ago. They now accept each other's marks. Yes, the HSD spindle and the Becker vacuum pump only have CE but are very...
  13. Re: Omni 1530 ordered and ongoing log of the process

    You are in the UK, so CE marks are OK, although there is no guarantee that your parts and wiring are to BS or EEC standards. Beware fire hazards. In Canada UL/CSA extended tests are required for...

    Poll: Re: CNC 6040 6040Z - China Made CNC Routers

    You should be able to get a rough total by adding up the watts or amps of all motors on the machine. 1500W (actually 1800W) = 15 amps and 700W = 1HP. Add 20% for surges or get a slow blow fuse. Dave
  16. Re: Omni 1530 ordered and ongoing log of the process

    Gfacer2, I received replies to my Alibaba, etc RFQ from 60 factories, received 3 fake UL certificates, got exactly the same stories about how CE was OK + quality from each one. Talked to them about...
  17. Re: Omni 1530 ordered and ongoing log of the process

    I did UL/CSA too. I provided everything required and they still couldn't get it right. The ground wires in one control panel build were black!! So remember the international wiring colour codes. Once...

    Re: Omni 1212 Delivery

    You have many choices for shipping denoted by abbreviations. FOB seems the cheapest, but is paperwork intensive and you pay all the fees. I chose DDU. This means that the factory and shipping agent...

    There is a trade off here involving convenience, cost and technical safety. The CSA costs more for a field inspection, but have a lot of extended safety standards. In talking to my local CSA branch...

    Local inspection is possible for ~$500 by your local city inspection group. That is the first place to start. They will ask for a few changes and apply an ETL sticker. David

    Re: 3 phase 360V electricity for CNC machine

    I posted the international colour codes in the Chinese machines forum. What they do is use whatever wire is used for the domestic market and leave you to replace it. That attitude must change.

    G59, you're correct. If you're buying from Ebay, then 'caveat emptor' applies. Many Chinese suppliers of household goods do meet OUR safety standards, but with the tools and certainly CNC machines...
