Welcome thread-tell us about you.

[Diver66]

Just a draftsman, some programming, electronic hobbyest, r/c fan, and an all around tinker. Love to build stuff hopefully will be able to build first machine this fall, must build shop to put it in, current one too small. That is my story and I am sticking to it if my wife asks.;-) Great site and lots of information and great advice.

Thanks
Barry

I'm an ex-drafter/designer turned Computer Programmer. I'm building a 3-axis machine with the help of a book by a Cannuck named Geoff Williams. I've got my boards built, except I still need one more motor driver chip. The two boards I have completed have the coil windings energized when I power the boards, but for the moment I'm having trouble making them turn with the software.

If anyone has any specs for these little airpax 82227/B82359 steppers, that would help me make sure I have the coils wired correctly, but I can't find anything, so I'm guessing. I might just end up buying some new motors complete with documentation, since I'll need bigger ones for my final design anyway.

BTW: I'm in Denver, CO.

Hi all
Soaking it up like a sponge. Hope to squeeze out a machine soon.

How do I post a new Thread?

hello all ,
gosh!!!!! i just CANT write a simple hello...erased this 5 time now i got lots of questions ,i know about machining (been machining for about 10-11 years) but i dont know much about building cnc machines ,or the power of a stepper motor or the controlers,other than what i have read here and on other sites,better to not clutter up this with with all my questions ,still searching to see if i can find the answers that have already been posted here,so as not to go in circles over and over asking the same question that im sure have been answered already!!


there i go again rambling on better quit while im ahead....

Hi All.
Just been lurking and reading for a while. I am slowly gathering all the stuff needed to build the jgro cnc table. Already have a Xylotex 3 axis board and steppers, I just need more time. Too many other things going on in life to devote the time I would like to devote to CNC.
I will post some pics when I get to the point of actually building.

Erkiwi You go to the general forum list...Which is at the top left, ...the ultimate machinist community. Then pick the general topic you want ...for instance.... General Metal Working Machines Once that is open you'll see start a thread or start a new topic...

Just arrived. Looking for information to upgrade my SHARP with an older Millpower 2 axis CNC. Machine's tight, but the old OS and software are way old. CNC's very nicely, but system can't except G-Code or DWG/DXF files everything must be programmed in manually.

Anyone got any ideas on the way to go on this, a new Millpower system looks like 10K. I'd like to get in for less than that.

A Newby! Just purchased a RF-31 Mill/Drill, now need to learn everything!
Thanks to Boosted & RLC for questions answered.

I was wondering if anyone has built the "Workshop Bot", based on the book by Geoff Williams. I like the size and the frame design, and but the electronics needs to be updated. I was thinking some servo's from http://www.homeshopcnc.com/page4.html , with the Geckodrive.
So is there anyone out there with some guidance.

Thanks for your time.

I'm a bit of a beginner myself, but I am building a Machine based on Geoff Williams book. The issue is of course primarily finances, but I have built the circuit boards as described in the book. I'm not sure why you say the electronics needs updated, but as far as I know, the design is functional. I still need one more L298 chip to finish my third board, and the two boards I have finished have not yet moved a motor, but I think it is either an interface problem or a motor coil wiring problem. I have no specs for the motors, so I have made an educated guess as to how they should be wired. What I get when I power up the boards is energized motor coils, showing that power is getting through the circuit to the motors, but I can't seem to make them move with the software...yet.

I'm probably going to build another set of driver boards, and on the second set I want to put a connector in to utilize the 'motor enable' feature of the chip and software. That is a pretty simple modification. I'm also going to do my own design for the table. I have no space for a setup like his.

I did a search on the site, and found that, blfuller123, under "My first cnc router", is in the middle of building his version based on the same book.

It look pretty sweet, so far. Nice pic's.

Good luck on your design.

I will be out of touch for a week or so. Work is getting in the way of my life.

I will check in again in a week.

Best Regards to All.
