Thanks Tom for taking the time to post the explanations. Sounds good.
Step&Dir or SPI (Serial Peripheral Interface) motion command.
Advanced SPI motion with up to 255 points 32-bit fractional interpolation and 8 x 32-bit FIFO buffer.
The spi functions will be implimented by using a DLL. The drive will buffer the commands if they come from the control faster than they can be implimented. This will provide for smooth motion. |
I like the sound of this feature. I have a current problem, if I use the exact stop mode in mach2 it will cut circles with jumpy jerky motion. If I use the constant motion mode instead it will cut off the corners on a square. Will the new feature help to slove this issue? Sounds like it should. In essence, mach2 will give the driver cards the steps and the cards will store the steps until they are carried out. Yes? If you have truely solved this problem then I expect there will be a lot of happy customers out there.
EDIT: Upon thinking about it, the mother board will store the code and not the driver cards, otherwise how could the gcode be co-ordinated to drive all the axis at the same time. Yes?
Encoder fault detection - no motor runaway with faulty encoder. |
I am glad to see this feature. I have seen this problem first hand.
I dont suppose you take trade ins of the old cards, Or even better swap overs
Maybe I could do a review of your new cards as a swap
(3 axis setup)
EDIT: Hey ViperTX from the sound of it, it may just be worth the extra wait, maybe Vlad/Tom might do a one off deal for you?
EDIT: Tom, I know this guy who is also about to launch some new drives too.
He disputes the high current claims that Rutex makes. He says the green conection plugs are ony rated at 12 Amps. What do you say about that?
Also I would prefere to see screw terminals instead of the plugs ( Just on the high current sections)
