Hi All:
Well, whata we got this week....(I'm now keeping a better filing system so I'll list from my copius notes... 1) Close file button added. 2) Reload last session file button.. 3) BackLash error fixed. (Thanks Isak) 4) Rutex stability in PID variable readouts. 5) CV-OFF LED OEM function is added (OEM #56) 6) Not pressing enter when entering a jog incr will no longer cause a 0 to be entered. (Which was crashing the program) 7) Index signal is now debounced to eliminate spurious noise. This means the width of a spindle index must be equal to your interrupt period * Debounce interval before it is assumed to be valid. 8) Dwell G04 may be in milliseconds or seconds. Selected on the logic screen. Small bug to be fixed for next version is that you must restart program after changing this value. Thanks, Good luck, (Special driver has been updated for it as well.)

Steve:
The debounce inetrval now applied to the index pulse. This means that when the index sigmal goes active, it must stay active for the number of debounce cycles. Lets say your dedounce is set to 20, this means that any signal, including the index signal, must be active for at least 20 interrupts or it will be ignored. So, if your using 25Khz, then one interrupt is 40us and times 20 is 800us, so the width of the index pulse must be at least 800us to be recognised. This should elimiinate any noise or reflections from triggering it. If you have a 1ms pulse width, then it should read fine. I think I will have to give you a separate debounce interval for just the spindle beacuse the width of the pulse will, of course, vary with the RPM of the spindle. This means at high speeds, you may not read the index at all if the debounce is too high. I'd be interested in what your spindle RPM now reads and if its more stable. Thanks, Art www.artofcnc.ca |

Art: Still in development, so at this point, it simply reads the PID values (the pots) and displays the current pot reading. This is only valid if your using the Rutex motherboard and have the SPI jumpers installed. Thanks, Art www.artofcnc.ca Yahoo!

I'd be interested in what your spindle RPM now reads and if its more stable.Not brilliant news :( All tests at 400rpm Debounce 20 50 50 100 Normal Spin count 3495 3492 3541 failed Current Spin count 7339 5124 5836 Adder 3344 1966 1846 Adder is still counting millions for ages after spindle starts and there is a distinctive jump in X & Z axis as it stops counting and then decides to move in for cut. Z moves are not smooth and it is only half way through a 10mm long thread that feed is consistent. Displayed spindle rpm is much smoother, but I think there is still something wrong somewhere. Spindle speed is not changing throughout all this but Mach2 seems to be displaying or "sensing" a slight slowdown,as Z axis moves, my tacho says it's not? -- Steve Blackmore |

Steve:
Well, the adder values are correct for the sensed speeds, but the sensed speeds are still screwed up. I will redo this section, hopefully tonight, and see what can be done. Separate debounce setting for index is obviously a must and will be added immediately. I will try to simulate this problem and see what happens. I'll set up a step/dir control on my spindle output to see if I can make these same values happen.. I'll let you know, Thanks for the tests, I think we're slowly getting there...

It is a method for controlling the speed of a spindle through Mach2. My partner Jim Cullins is working a special PC board to use with Mach2. Bob Campbell ----- Original Message -----

Step/Dir spindle sends out a scaled constant step/dir pulse to control the
speed of the spindle. It is ramped up and down just like a motor. The thought was I could use a Gecko320 and a 1-2HP servo motor as a Lathe spindle motor. Not only could I get a very low speed, but I could do 3d images on the lathe by moving the spindle as a controlled axis for 3d work. I will eventually get there some day. (I even have the Gecko320 waiting for it.) Art www.artofcnc.ca |
