I work with Industrial grade routers and they move 1000 plus pound tables at 3120 in per minute and stop on a dime plus having .0001 accuracy. Harko...
That must be some servomotor! A dime is 0.7" in diameter (I just measured one). To "stop on a dime" when moving at 3,120 IPM calculates to 5.03 G deceleration...
I have to admit I didn't actually try this but I don't think it would be reliable. During my testing I had problems maintaining steady data transfer even...
Hi Dennis, ... Actually this doesn't matter. The precision timing is done in hardware. The spread spectrum is only a small timing jitter and has negligible ...
... I know its been a bumpy ride to this point, but on the plus side is we're sitting on a nice piece of completed hardware now. Is it out of the question to...
Ah,.. 300 times slower rate of accel (150ms / .449ms) requiring 300 times less peak power invested in acel/decel. 29.55kW becomes about 100W now. Mariss ... ...
Lest anyone get the wrong idea, the G100 will always be available. We have no plans to ever withdraw it from the market because that would make no sense. The...
... That would be excellent! One of the main things keeping me from designing an ARM board for the G-Rex is that there was no way to change the FPGA code...
Hi Harko, Those are very impressive specs, can you tell us more about the machine, motors and drivers? Do they use rack, belts or screws? I don't see how...
... Mariss, How do the concerns and issues put out in this thread effect 5 and 6 on the list? I.e. is Mach going to be the bottleneck that it sounds like it...
Mariss, you are an exceptional person! Thank you for setting the standard if fairness and compassion. Jim C. ... Lest anyone get the wrong idea, the G100...
Steve, The G100 hardware was designed from the get-go not to be married to any particular processor. The main board appears as just another 8-bit I/O...
I hate to ever give up on something. I try not to turn my back on an idea and never revisit again. Number (5) will make for a very good servodrive by itself...
I'm kinda new in this subject, but I'm working in a project where we want to control a 4 axis Scara Robot using the Grex 100 and Mach3. Initially we would like...
Hi Steve I am very interested in your plans for the grex and ARM daughterboard. I would really hate to abandon the grex and use it as a doorstop. There is so...
... be ... would ... buffer ... you ... Les, you could be totally correct about this, but it still seems to me that if we consider implementing G100 code that...
I agree with Paul, if some redevelopment does get going with the G100, I wish you would discuss what you are up to, it is over my head in many ways, but little...
... Yep - I know the bus/connector pinout is in the manual. I'm sure that a non-Z80-like processor can be mated to it just fine. There are changes that I'd...
... I don't have a definite plan yet. I've been trying to decide if it makes financial sense to do the work :) I have been considering the Atmel 91SAM7X...
... There are PCI and parallel-port connected FPGA-based solutions that can generate step rates into the MHz range. These work with EMC2. The PC then runs a...
Well, not to throw too big a wrench in here, but have you looked at EMC2? There is a kinematics file (and a sample config) for SCARA included with the...
Hi Steve, ... This is exactly what Mach does, which is why pause takes a little while to respond and stop immediately stops pulses with no deceleration. ...
Hi Paul, ... As I mentioned before USB or Ethernet add quite a bit of extra potential delay. They are nowhere near as high priority as Mach's pulse driver and ...
