The THCAD-10 has 100K of total input resistance in its input divider section giving it a full scale input range of 100K*100uA = 10V. When external series resistors are used to extend the input voltage range, the required resistance value is: (VFS - 10V)/100 uA Where VFS is the new full scale input voltage and REXT is the new external series resistor. For example, to extend the THCAD-10s input range to a 500V a (500-10)/100uA = 4.9M resistor would be required. -- ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users Peter Wallace Mesa Electronics (\__/) (='.'=) This is Bunny.

[Emc-users] Inverting lathe X axis arrow key
Hi Guys, I am tuning the axes on my rear-mounted turret lathe and am having problems with the X axis. In the current state, pressing 'up arrow' on the keyboard moves the turret forward (towards me) instead of back. The diameter readout increases as it should and any MDI motion commands in the X positive direction result in a correct move of the turret towards the back/away from me. If the lathe were a front-mounted post type, everything would be perfect, but since it's a rear-mounted post type the arrow is backwards. I'd like to be able to press the up arrow key and have the turret move away from me without affecting any of the other things that are working correctly. Anyone have a solution?

How do I calculate, what is the resistance of additional resistors needed to reduce max voltage from 300V to 10V? The unknown element here is the current that passes through THCAD card. Viesturs That would be a 30/1 ratio, but would need to be a high enough resistance to not draw source or resistor destructive power, and if using carbon film resistors, the higher value resistor connected to the JasicCut should be in the form of several lower value resistors in series so as not to over voltage the carbon grains and destroy them over a log period of tie without their ever getting hot. If the load end load is 10k ohms, then the high end of the string I would make from 11 each 27k resistors, which would total 297,000 ohms and should, if they have sufficient wattage ratings, last nominally until the rapture. Half watt resistors s/b plenty good enough in that case. The resistor tolerances should give a very slightly higher reading, a percent or so, but linuxcnc can probably calibrate that out if it is that critical. I would much prefer to use metal film resistors as their failure mode doesn't seem to have the long term drift in values that bulk carbon or carbon film resistors are prone to. The values I quoted would result in only a red hair north of 1 milliamp of draw at the full 300 volts. That may not be enough, so dividing everything by 10 might be in order. 1000 ohm load, and 11 ea 2.7k's in series says its still under 5 watts total if I am running kcalc correctly. The likely hood of that isn't good, so please check me on that. 11*2700+1000=31700 ohms for the whole string. Then 300 / that=0.0097719869706840390879 amps of current flow, then wattage is usually calculated by me as i^2*r so the i squared is i^2=9.5491729355218623009e-05, and that times the total r of 31700=3.0270878205604303494 which is a red hair north of 3 watts. But since that 3 watts is effectively spread over the 11 2,7k in series, that is then worst case = 0.27518980186913003176 watts per resistor, so half watt resistors in metal film should be fine. 1 or 2 watter's should last forever. Other that striking the arc, do plasma cutters ever work at more than 75 volts? Cheers, Gene Heskett -- There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.

[Emc-users] Announcing the LinuxCNC 2.7 branch
Greetings LinuxCNC people, I bring you glad tidings! One of the things we did at the recent Hackfest in Houston was creating the 2.7 branch. We will test and stabilize the code in this branch, and when the time is right we will release 2.7.0. I'm hopeful that the time until 2.7.0 is released is on the order of a handful of months. The headline features in 2.7 are: * A new high-speed trajectory planned (written by Rob Ellenberg) * Support for the RT-Preempt realtime kernel (written by Jeff Epler) In addition to the new RT-Preempt support, LinuxCNC 2.7 will run on RTAI and the vanilla Linux kernel just like 2.6 and earlier versions do. We are currently targeting the same set of Linux distributions for 2.7 as we did for 2.6: Ubuntu Lucid, Ubuntu Precise, and Debian Wheezy. The final set of supported distros may change as we get closer to release. This new branch does not mean that 2.6 will go away. I will keep maintaining the 2.6 branch and making releases as needed. Your CNC machines running LinuxCNC 2.6 will stay supported with bug fixes for a good long while still. So, you're asking, how can I help? I'm glad you asked! You can run the 2.7 pre-releases and submit bug reports! There are probably some rough edges and possibly lurking bugs that we'd like your help in finding before we release 2.7.0. You've been warned! The install instructions leave a lot to be desired at the moment, but it goes like this: * Install LinuxCNC 2.6, for example using the instructions here: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?UpdatingTo2.6 * Upgrade to LinuxCNC 2.7 by picking an apt source line from here: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?UpdatingTo2.7 Happy upgrading!
