I/o Range BF00-BF07
I/o Range BE00-BE07
I noticed the commonality between the various PCMCIA to Parallel cards it that the first number of the top line in the I/O range is the port to enter into Mach3.
Here is what I had to do to get smooth operation:
* XP sp2 HP Pavillion 1.7 ghz dual core laptop.
* 3040 typical ebay brand CNC router / engraver.
* Card is ebay cheap brand "Best Connectivity" purple label.
* Mach3 Port & Pins > Kernel speed = 100khz.
* Mach3 General Config > Input signal debounce set to 1 or more.
Before my motion was very loud, slow, and jittery. Every once in a few boots the motion would be good. None of the motor tuning settings helped. Disabling all non essential services did not helped. Change powercfg settings did not help. After 2 days of fiddling around I pushed the kernel speed to 100khz. CNC moved smooth 50% of the time. Then I adjusted input signal debounce. Worked perfect after that.
