in the Simple Step pdf. It's on the next to last page and is their FAQ. -quote- Q. How far can I move if your board can only step 65,534 steps total travel? A. If you have a mechanism connected to the motor that allowed you to move the unit 0.001 inches per step, you could travel 65.534 inches (5.4612 feet) total travel. Another example would be a mechanism that had an 0.01 inch per step resolution which would allow you to move 655.34 inches (54.612 feet). -end- Now if you wanted 0.0001 increments, which is often talked about here, would you be limited to 6.5534 inches total travel per axis? Sounds like it from their answer. If you went with 0.0005 then ~ 13 isn't so bad. Ray Message: 11 [CAD_CAM_EDM_DRO] Digest Number 483 |

300 oz inches would be better. I put those (300) on my retrofit and they worked very well. One other thing you may want to do is the replace the X-Y leadscrews with ballscrews. On my mill drill I found the original acme lead screws had a pitch error of .001 per in and .02 back lash. With ballscrews I have <.002 and the pitch is right on. I also solved the mill drill quill backlash problem (.02) by modifying the pinion shaft and making some simple eccentric bushing for the pinion shaft. I have a write up on it somewhere. It was easier than adding ballscrews to drive the quill. Dan -----Original Message-----

Re: Digest Number 482

Re: PROJECTS STILL ON THE BURNER?
It now appears I can get my Beast (the 1984 Leadwell-Ramco) of a milling machine to accept drip-feed input through its RS-232 port. I tracked down the people who made the old Centurion IV control (they are called Milltronics now, and are located in the Minneapolis area) , called the number (952-442-1410) and talked to "the old guy in the back". He assured me that if I could be happy with a 1200 baud rate, could come up with some kind of "BTR" (Behind The Reader?) box and appropriate shielded cables, and found a control program that could output my G-code as step and direction through the serial port of my computer, using Microsoft's built-in Hyperterminal or some other null modem connection, then I'd be in biz- able to feed it unlimited-size files in DNC mode. This sounds distinctly doable (much more so than the Brain Transplant), but I've got some questions for the experts here: What control program should I use to communicate with this old DC servo-equipped mill? Is this a good excuse to try CNC Pro, or would something else be better? Is the DOS port of EMC really ready and for sale someplace? I think this would go fast enough on my P223, in DOS mode- wouldn't the low baud rate be the limiting factor? How many inches per min. should I expect, in contouring mode? Do I really need some special BTR box, or can I go direct from the 9-pin serial port of my computer? Does this machine need its code fed in some special way, which the BTR translates from standard step-and-direction? If I do need one, which is the most cost-effective (for an non-electronician)? What about the "software handshaking" it uses: x-on x-off? How does that work? Is this just a series of characters I need to insert at the beginning of each program, (and if so, how do I find out what they are?) . I was thinking of Predator cables- anybody had any experiences with them? Predator also had a $700 control program (with cut previewing and other nice features) - anybody tried it? I'm sure I'll have more questions as I go along... Andrew Werby Andrew Werby - United Artworks Sculpture, Jewelry, and Other Art Stuff |

It makes claims almost as outrageous as Hurco, implying a vastWhat conspiracy? It's front and center in the USPTO's press releases. The USPTO has been reorganized to run as a business. Its tax funding has been reduced to only partially cover its budget, and a profit motive established to encourage serving its customers. The USPTO views its customers as the patent applicants who pay them filing fees, not the general public concerned with the progress of science and the useful arts. ----- [...] The PTO has evolved into a unique government agency. Since 1991-- under the Omnibus Budget Reconciliation Act (OBRA) of 1990-- the PTO has operated in much the same way as a private business, providing valued products and services to our customers in exchange for fees which are used to fully fund our operations. The primary services we provide include processing patents and trademarks and disseminating patent and trademark information. [...] ----- [...] Performance The mission of the patent business area is to help our customers get patents; its performance goal is to grant patents to inventors for their discoveries. These were established to help us direct our efforts toward providing our customers with high-quality service, one of the PTO's two strategic goals. [...] ----- PRESS RELEASE #00-21 CONTACT: Richard Maulsby March 29, 2000 Maria Victoria Hernandez 703-305-8341 PTO BECOMES PERFORMANCE-BASED ORGANIZATION Today, the Patent and Trademark Office (PTO) becomes the United States Patent and Trademark Office (USPTO), a Performance-Based Organization (PBO). The new status results from the American Inventors Protection Act of 1999, which reformed the U.S. patent system in a number of ways. The PBO is a concept created in March 1996 by Vice President Al Gore and the National Partnership for Reinventing Government. In fact, the USPTO will now be only the second federal agency in history to be a PBO, after the Education Department's Office of Student Financial Assistance. A PBO is a results-driven organization that delivers the best possible services to its customers. A PBO also commits to accountability for results by having clear objectives, specific measurable goals, customer service standards and targets for improved performance. In exchange for this commitment to accountability, a PBO is granted managerial flexibilities to achieve these goals and operate more like a business with greater autonomy over its budget, hiring, and procurement. The USPTO's new status will be celebrated this Monday, April 3, 2000, at a ceremony in front of the main headquarters building at 2121 Crystal Drive, Arlington, Va. The program will begin at 10:30 a.m. "As a PBO, the United States Patent and Trademark Office moves to the forefront of reinventing the federal government by becoming a results-driven organization with a renewed focus on customer service," says Q. Todd Dickinson, Assistant Secretary of Commerce and Commissioner of Patents and Trademarks. "Having sufficient resources to operate effectively in this new environment," he continued, "is now more important than ever." # # # |

I have read the notes about patent issues and am now concerned.

Date: Fri, 05 May 2000 06:57:59 -0400 Ron, Take a look at for the intelligent driver boardsthanks for the note, I pulled the docs on Friday and read them over. It does indeed sound like a fine way to run steppers under windows. I think I may order one and try to modify my current VB program to drive them. The only tricky part is getting the timeing right to cause the motors to do a ramp move. The SSXYZ board does say it uses a common clock so all motors will keep together within a few microseconds, but it looks like you hve to calculate the time for each axis first. Ive sent a message to them for clarificaiton. A 2 amp board for 3 axis is about $350. This beats FlashCut by a good deal. And thy have a big 6.5 amp board for aout $400. Looks like some good stuff. ron |
