all axisis "twitch" every 5 seconds with nothing running. i've deduced that it has something to do with the parallel port as it goes away when i disconnect it. dont think its noise, when i disable the port it goes away. i read somewhere that the bios needed to be reconfigured to EPP, did that and still get the 5 sec twitch.
i am etching printed circuit boards and during the run my z axis ends up higher and therefore stops etching, i believe it has to do with this twitch and missing or corrupting signals during the run?
could really use some help, not much hair left.
thanks!
