(a hassel to use in that manner, but fine for testing ) so I have looked at the source code and cannot see that bit being set. My understanding of C is very aboriginal.

[Emc-users] Change of Home Position
Hello Everyone, Over the last few nights Ive experienced a coupled of odd events with EMC 2.1.7 normally runs flawlessly. Running AXIS Ive homed all axes to zero and then commenced running my Gcode. Last night the Y axis home position appeared to jump by 0.400 (as seen on the DRO), axis still reported Y home at 0.. Tonight a similar thing happened with the Z axis. Initially DRO Z and AXIS Z were zeroed and followed one another to within ½ thou (which is okay for me) then following a return to Z = 0., the DRO read +0.0250 and AXIS still reported Z=0.. The cutter was obviously offset from the workpiece so I stopped the programme, rehomed everything and started again, this time with no problem. Has anyone else experienced similar behaviour Im guessing not since I havent seen any posts. Regards Andy - This SF.net email is sponsored by: Microsoft Defy all challenges.

Re: [Emc-users] Xylotex Stepper Board
I'm using a xylotex 3-axis board. I'm pretty happy with it so far. For whatever reason, my machine moves reliably at higher speeds (70ipm instead of 40ipm) in half-step mode than 1/8 step mode, though most people seem to prefer using the board in 1/8 step configuration. The connections are very simple: PC to xylotex with DB25 M-F cable; 24VDC connection from power supply to xylotex; 4-wire connections from xylotex to each motor. In stepper_inch.ini or stepper_mm.ini, change standard_pinout.hal to xylotex_pinout.hal There are probably other all-in-one boards, and emc should work with any board that takes step+direction inputs that match the PC parport for voltage and current requirements. Geckos also work fine, though I understand that the other models *besides* 203V have input current requirements that may not be met by all parports, leading to the use of an extra board in between with its own 5V supply and line driver IC. Someone who's actually used geckos should add them to the wiki. Jeff - This SF.net email is sponsored by: Microsoft Defy all challenges.

For instance, my Universal Stepper Controller : http://jelinux.pico-systems.com/univstep.html It is only $250, and it allows you to connect encoders so you can detect actual position at all times, even when you crash or hit E-stop, it also has opto-isolators for 16 digital inputs and positions to plug in 8 solid state relays for spindle, coolant, etc. Finally, it supports spindle sync for lathe threading and rigid tapping. As far as I know, no one is working on interfacing the G-100 to EMC. Jon Some of us are still hoping someday to not have to use a parallel port to communicate with the CNC machine. I personally am hoping someday to be able to control EMC2 from my Mac (read no parallel ports). USB or ethernet look like the most likely prospects. The solution may be to use something like G100 or ARC100 at the machine and axis running remote but, we can always dream that someone will find a solution to allow EMC2 to operate over USB or ethernet.

Re: [Emc-users] gerber files to g-code?

This was just recently generated on a Mac, a simple pcb board for mounting a 27xxx eprom chip and plugging it into a color computer. Is there a convertor in the geda suite (or any linux free) that can convert this to our dialect of g-code, RS-274D? Well, no. The Gerber file is designed to draw the pattern on film with light, with the apertures setting the shape of the light beam. It can flash round, square, oval and thermal relief pattern in one blink, with one like of G code. You can't do that with a mill. If you want to actually cut a working PC board with a router bit, you need to convert the file quite radically with a trace isolation program. It figures out which traces and pads are connected, then draws a series of moves around the entire extent of the net. Eagle is one of the programs that can do this, but the somewhat odd format of this file may be an obstacle. Could the person who made the file on the Mac specify for trailing zero suppression on these files and re-generate it? I believe I could then read it on my Protel software, for instance, or make it plot on my photoplotter. The industry standard is for Gerber photoplot files to have Leading zeros suppressed, and for Excellon drill files to have Trailing zeros suppressed! All part of the history of the electronics industry, dating back to punched paper tape. Jon I'll check with the author, it could be he isn't that fam with the usual ways of doing things. Thanks Jon. -- Cheers, Gene There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.

Re: [Emc-users] G100+emc2
The Mac mini's are very tempting. Duo 2 core. 1.8 GHz . Runs OSX ( BSD unix ) with an Apple replacement of X on top. AFIK X the proper compile of X runs just fine. The only problem is the lack of EMC compatible I/O. The mini's have USB, Ethernet, and Firewire. The really nice thing is the package ... about the size of 6 CD cases stacked. I have no data on how well it runs with a linux/rt kernel. Anybody have any data?

Run each machine's EMC headless and make an NML socket to whatever machine you want to use to run it. We demonstrated that it could be done from a MS-OS at the NAMES show in about 2000 or 2001. I was running a box 200 miles away the other day using an Xterm. No need for anything special and I think Mac can handle Xterm about as well as Linux. At the price of PC's these days you can probably get this sort of setup for less than the base price of a G100.

There are a number of cheaper, more capable interfaces to step/direction drives that give you a number of advanced features the G100 still lacks. For instance, my Universal Stepper Controller : http://jelinux.pico-systems.com/univstep.html It is only $250, and it allows you to connect encoders so you can detect actual position at all times, even when you crash or hit E-stop, it also has opto-isolators for 16 digital inputs and positions to plug in 8 solid state relays for spindle, coolant, etc. Finally, it supports spindle sync for lathe threading and rigid tapping. As far as I know, no one is working on interfacing the G-100 to EMC. Jon Some of us are still hoping someday to not have to use a parallel port to communicate with the CNC machine. I personally am hoping someday to be able to control EMC2 from my Mac (read no parallel ports). USB or ethernet look like the most likely prospects. The solution may be to use something like G100 or ARC100 at the machine and axis running remote but, we can always dream that someone will find a solution to allow EMC2 to operate over USB or ethernet.
