Re: [Emc-users] Rapid Prototype for CNC mill
Hi I did ask about rapid prototype machine and got helpful directions. I check about reprap technology Those all was close but not what i ask for. I am looking for real - real- rapid prototype. What this means ? 1. rapid prototype should have 2 liquid materials-- main material and support material. 2. rapid prototype must have CNC programmable head - like with EMC2 AC servomotor that open close needle valve that controls amount of plastic that introduced with head. 3. rapid prototype must have accuracy around on 0.005 to have real use to make real commercial model prototype. CNC programmable head must be able to change accuracy from 0.001-0.01 by changing M code in CNC program. EMC2 is good to use for that --by allocating 2 or 3 programmable axis only to control head of real rapid prototype machine. problem with reprap is that their main idea is to make cheap machine -under $ 1000- but not real rapid prototype machine. Real head for rapid prototype machine may cost a lone up to $5000 and shop will buy it because with it one can convert any size of CNC mill into high performers rapid prototype machine. thanks aram -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

From what I've seen looking into USB 2.0 device programming, the transfers are too quick for most (maybe all) microcontrollers to keep up with in software, so you are generally tied to DMA transfers on the microcontroller side. FTDI has some chips that eliminate the DMA issue for the programmer, but they may do DMA internally. There is a mode called 'isosynchronus' where a peripheral negotiates a certain amount of transfer for every time USB transfers data. This mode can be used for more reliable data streams. I suspect that a high bandwidth peripheral that has a USB port all to itself will not be as problematic as one that contends with a mouse and keyboard for the port. I also suspect that the USB connection has a certain period between communication events. A base period that gets lots of real time errors from contention with USB*/may/* have much less problems with both faster and slower base periods. Perhaps when documenting what works, and what doesn't, it would make sense to keep track of: 1:USB 1.1 or USB 2.0 2:What is the device? 3:Does it have the port to itself? 4:Is a hub being used?

Re: [Emc-users] Rapid Prototype for CNC mill
Although I don't have any inside information, I believe the reason DIY 3D printers have (or don't have) specific features is that most of the original patents remain in effect. Patent in US has only 15 years life. I have US patent personally on my name - not through any company etc. I can write patent application to US PTO my self and pay only standard fee. In special case -like pharmacy drug patent life can go up to 18 years. That is all. All those patent that you refer are too old and antiquated. Every manufacturing company incorporate in there product 2 parts. Part 1- is what customer need and willing to pay. Part 2 is add things that only increase price -costumer does not need that at all - and can not be option out. About waffle iron i think that all EMC2 is people that do just that.

Only knowing about the taskset command for the last few hours, and not knowing how linuxcnc does things, I'm learning as we go along. We'll see how this BASE_THREAD of 25000 test goes - even if the whole of LinuxCNC is on one cpu, as long as it seems to work without croaking, maybe that's all that is needed for my config.

By the way, The Axiom card is a Digital I/O card supported by HAL. I was kind of surprised that everyone assumed that it was a video card. The card is the Axiom AX5214H as described in the Linux CNC Docs. The problem was caused by an ATI Video driver that was not removed when I pulled the old video card out a while back.(Long before the DIO card was installed) Don't know why it caused a problem after the DIO card was installed but removing the old video driver corrected the problem.
