That, and another 10 volts of motor power, will triple the speed of an air cut. In your ini file, there is a debug enable setting, which can make the terminal show a lot more info than is shown above, see the docs for a very terse description of what does what. Thats not saying I detest the gui, but because I'm getting more capable at pyvcp stuffs, my axis gui keeps adding more things that will be or are usefull on that machine. Like on this lathe I'm rebuilding and converting, now has a spindle tach, 3 buttons under that to tally motor power and spindle direction if its on and turning, and now two more below that to show the currently selected size of the move for one detent click/move of the dials I put on the front of the apron. Still not done with that, but making progress ATM rebuilding the countershaft because someone back in the mists of time, changed the spindle drive belts and re-installed the spindles drive pulley backwards on the shaft, so that when the belts were aligned, the pulley missed the key, threw it away, leaving the setscrew to try and hold it from slipping. Horrible failure, and both the shaft and the pulley bore were eat out by the slippage. So I am fitting it with a taperlock hub, currently clamped down on the mill table with counterbores in the flange for the draw screws yet to be bored, and the tapping of the holes which will be done by rigid tapping on the mill. No hurry as amazon won't ship the last of the bearings for at least another 2 weeks. The manual I have on this style of drive says the two shafts are spinning in a pair of needle roller cartridges on each end of each shaft, but when I took it apart, they were bronze bushings and running too hot regardless of the grease I pumped in. > John suggest I open an issue on this but want to make sure I am not > including something that I shouldn't or vice versa before I do. Thats the procedure, serving as a reminder that something needs some TLC. Some of my own code could stand a lot of that. OTOH, like this, it works anyway. :) But getting rid of cruft is always a good thing. I often long for the days when every byte of code had a memory cost, it made us carefull when memory was $400 for 4k of static. > Regards. > > Joe Hildreth > > > Interesting comment, John K. > > > > So I fired up the editor and took both CYCLE_TIME settings in the > > .ini file out of the ini file for my small mill. > > > > On running it, trajectory did not complain, but emcio did, saying it > > was useing the default timing of .01 seconds, same as the ini file > > setting.

I'm assuming that the two things you want aligned are the bore perpendicular to the large face and a key way in the base. I was wrong in referring to the key way as a t-slot. In the original mail you were referring to making a hole perpendicular to and aligned to the center of the bore. Couldn't see a hole in the drawing and it looked like there was a key way aligning the center of the bore to the center t-slot of the table. One more setup then; large face down and face cut base, then base down and face cut large face, back to large face down and skim cut on base and cut key way on base. This gets the two faces perpendicular and the center of the key way perpendicular to the large face. >> sweep the two sides of the t-slot to center spindle on slot > When you say "T slot" do you mean the one in the table?

At 3 locations around the perimeter of this taperlock flange. Drive the machine to where the counterbore is to be cut, using that location as the X=0,y=0 center point, get the machine there and execute this subroutine: Machine is in g90 mode at the call. o<drill_countersink> sub s750m3 g1f1500 z#<_tool2work_offset> g91 (incremental distance moves) g4p.1 (queue breaker) g1 f200 X2.6625 Y0.0000 (move from center of hole to outer edge of counterbore in relative mode) g91.1 (relative I/J/K, is default mode anyway) g4p.1 (another queue breaker) G3 X2.6625 Y-0.0000 I-2.6625 J-0.0000 g90 o<drill_countersink> endsub When this works, the G3 will be converted for a spiral down to depth line, by placing that line above this one and letting this one clean up the bottom of the hole. popup on reload says its a 50% error, regardless of where I put the g91.1 or g91. Proper Fix? Thank you. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
