[Emc-users] For Jon Elson, Q on the 12 volts for the servo amp
Jon; I have some wall warts for a defunct portable phone charger base that measures, no load, 13.1 volts. I am considering using one of them for the 12 volts your pwm servo amp needs. This is not enough overvoltage to make a 7812 work, and if the logic draw is 100 mills I expect it will sag to below 13 volts. Is this usable as is?

Re: [Emc-users] Before i go bonkers: M98, M99
Instead of that M98 P1000 L9 use O1000 CALL to execute the subroutine once. If you want to execute it more than once, use a loop (REPEAT, WHILE .. ENDWHILE, or DO ... WHILE) You should also define the subroutines before the main program. So your program could be: O1000 SUB G0Z2.34 G1x-5 G0x5 O1000 ENDSUB G91 G21 F30 G1x-4.12 G0x5 O200 REPEAT [9] O1000 CALL O200 ENDREPEAT G0x2 G90 G0Z50 M30 % I have not run this, but I think it should work, minor typos notwithstanding.

As long as you can be sure it won't ever surge over 15 V when inductive stuff is turned off, it should be fine. The FET drivers and CMOS logic on the PWM amp have no regulation. I usually test with a 9 V wallwart power supply that runs about 11.8 V under that load, but that is just for the test bench. -- ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
Re: [Emc-users] Before i go bonkers: M98, M99
This is the solution.. Just needed to change the output to a diff. syntax model. It does basicly the same thing so. =) Thanks. // A Den 2015-07-26 kl. 14:55, skrev Dave Caroline: Linuxcnc supports subroutines with a different syntax http://linuxcnc.org/docs/html/gcode/o-code.html Dave Caroline On 26/07/2015, John Thornton j...@gnipsel.com wrote: Just because code is available in other controls doesn't automagicly mean it is included in LinuxCNC.

I usually test with a 9 V wallwart power supply that runs about 11.8 V under that load, but that is just for the test bench. On hooking it up to the servo amp today, it makes 11.56 volts with the last digit wandering 20 mv. So it should work. Whole box is now assembled, lid installed after blowing out any drilling debris from making the lid screws, and turned it all on with the switch on a surge arresting extension cord, no smoke, the night light used for a power off bleeder on the motor supply lights normally, which I believe is a good sign. Now I need to get another 5i25 from Peter, its blown something and will not initialize, or reflash. It was pulled partially out of the socket by the data cable while powered up, a definite no-no. Other cards installed in the same slot work fine. I'd clean off the shelf and put it in its final resting place, but its 50+ lbs I'll rest a bit before I try setting it on a shelf 6 feet up. Some furniture yet to assemble, some midden heap to move and dispose of too, so without a 5i25 card, I can spend some time doing that.
