I've found that the grizzly is much more rigid than all others minimills. if you want a benchtop cnc mill to do shortruns on aluminum,you better of buying a heavier machine. well, good luck! |

up to the task, you certainly can customize it if you have the skills. Ray Henry has done a real nice back plot routine that lets you see the tool paths. Tim [Denver, CO] -----Original Message----- |

If you are at all computer savvy and don't mind learning a little Linux ITim, Thanks for the feedback. The linux world is tempting, but the learning curve on all this is steep enough without throwing a new operating system into the mix. Perhaps I can get started with some cheap/free DOS based software and graduate to the open linux stuff later? Do you run the EMC software? I assume it's open source so if you're savvy you can customize it? Thanks again, Mike ----- Original Message ----- |

Ericsson distribution
Murray Leshner
Ah yes, but who stocks Ericsson? They had only two or three distribs in US,
but now with JRC/NJR, I want to investigate the old JRC/NJR distribution chain (they had 7-8 or so). Apparently 3776 (easiest way to drive discrete H-bridge devices) is discontinued. 3960 I would like to find for microstepping front end, as well. Murray |

Help: CNC mini-mill comparison
mnels@pobox.com
I'm sure this has been discussed before, but I'd really appreciate
any advice on a CNC mini-mill purchase. I primarily want the mill for machining plastics, PCB drilling/machining and some light metal machining. Some of the plastic work will be for semi-production use (so speed is important). The three obvious choices are: The MaxNC mills... probably the 10-2. It's the cheapest turn-key solution but I've not heard good things about the mill or the company. I've heard the spindle/motor mount has problems and the motor speed and CNC control electronics are very substandard. The rest of the mill looks pretty solid. A Sherline 5400 retrofit (probably Progressive Logic or do it myself). The wide variety of accessories for the Sherlines are great but the mill itself seems less rigid and durable than the others? Another downside is a low 2800 rpm max spindle speed. This mill also has only a 2.25" throat depth. The Taig Micromill. Using the MicroProto CNC package, it seems to be the fastest (30 in/min rated and they claim up to 60 in/min). It weighs over twice as much as the Sherline and is supposedly much more rigid. The CNC version has a max spindle speed of 8500 rpm which is better suited to our needs. It has a 3 5/8" throat which is a big improvement over the Sherline. It also has 1/2" leadscrews versus 1/4" on the Sherline. Does anyone have anything to add to the above? Specifically, does anyone have anything bad to say about the Taig Micromill? Thanks! Mike |

From: Doug Fortune < I'm looking for a source of planetary reduction gears to attach to my motors so as to increase torque and resolution (say 5:1 to 100:1 range). Have you tried www.wmberg,com or www.sdp-si.com both extensive sources for all kinds of motion control hardware. Not cheap in small quantities but good selection and service. SDP-SI has free catalogue/engineering manuals plus a B.C. Rep at 604 986-5953. Good luck Vance Buhler |

rt for mac
Ray Henry
RTLinux 3.0 Beta pre-release 4 released
FSMLabs releases RTLinux V3.0 beta hard realtime for 2.3 Linux (Socorro, New Mexico - March 3, 2000) Mac users I found this on the I don't have a clear picture what it means but may work to solve some of the problems that a mac user will have with an EMC running on that platform. FSMLabs released the fourth beta of V3.0 RTLinux[tm] today. The new version has been completely reimplemented to run on Linux 2.3 and to facilitate development of versions on non-x86 architectures. RTLinux v3.0 now includes Intel x86 and PowerPC ports. The PowerPC version has been tested and runs on various platforms (including Apple G3 portables, Apple G4, some RS/6000 CHRP systems, Synergy Microsystems VSS4 and PowerMac clones). Testing on other other PowerPC platforms is on-going. Ray |
