Folks, I've added a conversion of the asm that Mariss posted to Dynamic C for the Rabbit2300. http://groups.yahoo.com/group/geckodrive/files/G2002_101A.C Seems...
Dave, Just as soon as I get the boards back and tested, a portion will set in (liquid?) stone. That would refer to port bit assignments, external interrupt...
The purpose of the G2002 is to get around some shortcomings of PC based "software only" solutions for motion control applications. By making it open source,...
"My thinking is there are 3 ways CNC programs are implemented presently: (1) Software only, DOS based. Inexpensive and adequate pulse rates (100 kHz). Funky...
Mark, Jon Elson is a very intelligent and educated person who I respect. Rather than "rain on the parade" his contributions should only make it a better and...
Mark, Your #4 is really just #3 as far as the actual architecture. The editorial comments that Mariss added may not apply 100%, but it is still the same ...
I dunno what kind of file it is, but microsoft internet explorer 6 can display them. Eric ... __________________________________________________ Do you Yahoo!?...
Steven, A .wmf is a "windows meta file". You should be able to view it with Win98, Win2000, WinXP, ACDSee viewer, etc. When I get a chance, I will convert them...
Hi, Wouldn't it be easier and maybe even cheaper to have a PLD instead of the bunch of logic chips ? It should not be hard to port to a cheap altera or xilink...
Alexandre, Actually exactly that is in the works. What matters at this point is to get the first 100 prototype board sets out and the "glue-logic" version...
Hi, Mariss ... That makes the project look even nicer :-) I use assembly in my everyday work but I am a little rusty with Z80. I am starting to use C but I...
Hi, I uploaded to the files section, "G2002" folder, a picture of the axis card. This is a rendering from ACAD of the actual card (3D model) that has gone into...
Mark, Your #4 is really just #3 as far as the actual architecture. The editorial comments that Mariss added may not apply 100%, but it is still the same ...
... Most Windows crashes come from poorly written applications - not all of the problems and crashes are directly Window's related. I am NOT picking sides -...

I'm not completely sure I understand the project. I see that there are axis boards that look to be some sort of velocity generator yes? No? The main board...
Brian: Well, I'm sure Mariss will be around to explain things better on the electronics side, but as far as the serial data goes, the idea is to send...
Brian, Dave has it correct. The individual axis cards work in conjuction with the Rabbit to generate primative motion control actions. These include: (1) Point...
Hi I have revised the G2002 boards to include 2 GP outputs and 2 GP (general purpose), input per axis. This is different than the outlined schematic. I will...
Hi, The numbers show there are 63 members in this group. If any of you have questions or contributions, please post and do so. It would be great to have you...
OK... I'll take a stab at this... By training I'm an Electrical Engineer. I spent the first 8 years or so of my career doing embedded designs and software to...
I've been using the geckodrives on an EMC based CNC I built a couple years ago. I've been using the rabbit on other projects, and this combines both! I'm...
Hi Mariss, I guess I'm one of the lurkers. I've been thinking about a very similar project for about 12 months now, but as usual it's been pushed back due to ...
Hi, I know practically nothing about the project's hardware or the low level programming needed for it, however it is an interesting project and I'll be...
