Hi, When will we be able to purchase the G2002 ? I'd really like to try the new system on our machines. thanks, Rab, Rainnea CNC http://www.rainnea.com/cnc.htm...
Hello I have been thinking about the G2002 FPGA Register mapping. These are just thoughs at this time but it seamed worthwhile shareing them. Regards Peter The...
Hello, was reading through the old posts awhile back and saw reference to a paper about different methods of driving steppers which Mariss wrote. I missed that...
Finnaly, i start to understand how to treat a stepper motor, it just like a baby, a bold and heavy baby, as a baby SHE must be treated tenderly then she will...
Ball: Don't have Mariss' paper, but I DO have a link to some OTHER "stepper stuff" in which you may find something of interest: Jones: Stepping Motors Jan...
I have some nice 12v servo motors laying around. I'd really like to use a geckodrive to control it, however, the specs do say 18v+ on the geckodrives. I'm a...
You can run your 12V even with a 24VDC power supply. Just don't command the motor to go faster than its 12V rated RPM. If it's a small motor, set the current...
After almost three months without any success in finding a supplier to 74AC or 74ACT ICs in Portugal (unless I was willing to buy 5000 unis :-)), I accidentaly...

I seem to remember some kind person ... saying something about the possibility of a 'Lite' version of the developemnt kit ... without the C compiler maybe ......
Hi, Robin: I know that the WinIDE developer was asking how much we'd be willing to pay for an assembly language only version. A couple of us said around $100 ...
Hello, We are building ann x,y and z axis CNC router system, 5x10 table, steel gantry , very heavy duty and using Gecko servo drives for the motor control via...
Hi Rab: I think the G2002 is available now. But you either need a way to program it, (Programming cable etc..) or you need to ask Marris to flash it with a ...
I'm working on a controller card for my DIY CNC machine. I have unknowingly been thinking along the same lines as Mariss; I want a card that takes care of the...
... The FTDI USB FIFO chip used on the g2002 is probably just as easy to use as a MAX232 etc (RS232 driver), and gives far better performance. From the PC...
Excellent idea. It's called Bresenham's line algorithm. :) ... Ethernet is more trouble than it's worth anyway, until you get to a fairly heavyweight...
... performance. ... The reason for not using USB was that I thought it would require writing of device drivers, but if the chip comes with device drivers that...
... I haven't looked at the G2000 code yet, but... (I may be off a little in this, I'll have to look at it in depth sometime soon) For each line segment in...
A question -- Is your development intended only for your use, or is it intended to be a product that you offer for sales to others. If it's for yourself, then...
It is intended for me only - mostly for the learning experience (not to mention a CNC router would be cool :). But who knows, if it works out ok and there's...
... [huge snip] I didn't realise that :) I have used Bresenham's Line algorithm before, once, while trying to learn i386 assembler. I have to read up on this,...
Pleased to be of service. :) I'll be out of town this weekend (picking up my Brand New Used Bridgeport - woohoo!), but I'd be happy to discuss things when I...
Hi Art, It would be hard to think of a better combination for a controller than Mach2 for the software interface and the hardware coming from the Geckodrive...

Hi Rab: Marris seems to be hiding. That usually means he is deep in contemplation on viper or g2002 issues. (The man likes to think...). My g2002 is running...
Hi, Steve: Consider that a PC that runs DOS is fast enough to write a pulse train of several kilohertz that is stable enough to drive a stepper motor. This ...
Hi, Art, rab et al, Yeah, I'm kind of like in hiding because I'm digesting what is confronting me here. The Vampire drive has been consuming here. What started...
