[Emc-users] losing position
Gentlemen, I was just made aware of a recurring problem with the Cinci and the Enshu. I have heard nothing about the Dahlih. The Enshu is running 2.5.0-pre and Touchy interface. The Cinci is running 2.5.0-pre and Axis interface. Yesterday the Enshu lost Y position during a program run. The Cinci has done this previously but that was before the latest update to 10.04 and 2.5.0-pre. I did not report anything when the Cinci lost position because I could not be certain the problem was not mechanical. I am not CERTAIN the problem is not mechanical now but on two machines I have the same symptom. This leads me to want to report this. On the Enshu the Y position was incorrect by approximately .400 inch in the middle of the tool motion. Some correct cuts were made and then the tool plunged into the part in an incorrect position. Sending the machine to Y0 showed the misposition in the program zero. Homing the machine corrected the error. The same error repeated a little later yesterday during the run of a different part program. This time the error was in the opposite direction of the previous error. Again, homing the machine corrected the error. We have only seen this happen on the Y axis on both machines. Questions will be investigated/answered to the best of my ability. thanks Stuart -- dos centavos -- Forrester Wave Report - Recovery time is now measured in hours and minutes not days.

I agree with this IF the error happens all at once and IF the ferror limits are set to a reasonable number. If the error happens gradually (1 or 4 counts per servo cycle is gradual to EMC but pretty darn fast to a human) it would probably not ferror. Stuart, assuming you are homing to index, you can detect even one lost encoder count. Home the machine and note axis.1.motor-offset. Then move Y around or run a program, possibly losing or gaining one or more encoder counts. Then home the axis again and check that axis.1.motor-offset is still the same number. If not, the change in motor-offset is the *distance* lost or gained. -- Forrester Wave Report - Recovery time is now measured in hours and minutes not days.

If I can figure out how to tape it to the well soaked with various oils metal on my micromill on steroids, which does have a mister head when I load the reservoir, it will come in quite handy. I have some bellows material on hand, but haven't really set down with a sharp pair of scissors and a tape measure figured out how much I need and where. First addition I suspect would be some sort of a small bracket for the rear of the saddle that wouldn't restrict its toward the post motion if it can be helped, just to get a flat surface to lay a strip on sandwich the material in place.

[Emc-users] Axis Run Time display
The Run Time display available under the Properties menu item of Axis 2.4.6 on Ubuntu 8.04 does not seem to reflect the Feed Override setting.

[Emc-users] Stupid Questions from New Guy (Search Archives / Limit Switch Setup)
Apologies for being a totally virgin new guy here to this group. (2 stupid questions...) 1) Can you help me help myself? How can I search previous archives for specific questions? (I'd hate to interrupt the group to ask a dumb question that has already been asked..) I've tried different versions of google search site:news.gmane.org/gmane.linux.distributions.emc.user search keywords but the results there are of limited use. Is there a better search system that I should be using? (Note: I've not set up a newgroup controller with my internet service provider.. do I need to do that here? Browser system is probably preferred, if that is possible.) 2) I'm designing the wire harness for a 2 dimensional CNC plasma cutter. (DC brushed motor, optical encoder, Rutex driver boards.) I'm unclear on how to wire up the limit switches. On our drive axis, we have a limit switch at one end, the other end the driver gears fall off the drive track. I've got two switches, one for X axis, the other for Y axis which are normally closed to be used as limit switches on the appropriate end of the X,Y axis. I'd like to send that signal into the system, but I'm not clear on where I get a +5v signal source. Obviously I'd prefer to obtain a +5v reference directly from the parallel port. I don't see a setup pull down that enables an output pin to always be set high (at least using the visual parallel port setup tool) Can I set an Estop out port to use as my +5V source to my limit switch, and return the results to a parallel port input pin (10, 11, 12, 13 or 15?) Obviously I'd have to add pull down/up resistor as appropriate to clean up the signal. Anybody been here before? (hmmm. or is that inverted Estop out to generate a +5v source when ever the machine is turned on?...) Apologies if this question has been asked before. I've spent a couple hours looking, and nothing pops up as far as I can see.
