here is what lead up to this problem. i just replaced a first gen baord with a second gen after the old one went bad. i hooked it all up and after a very small amount of tinkering it all works. i can jog all 4 axis (foamcuttter) in both directions successfully. i could call for moves in the MDI box and all was fine.
I even ran a cnc program i used to run with the old board and all was perfect. somewhere after this, i lost ability to jog z the counter does nothing besides flicker and sometimes increas or decrease .0001 the others work fine. i can move z with the command line SOMETIMES but sometimes instead of z. A will move instead in a runaway sort of action. or sometimes a call for y will move a. sometimes g0 z-1 will cause a to runaway and z to move very slowly in comparison. this particular thing seems to only happen when the counter is NOT zero'd out. it will still run a file just fine. i dont understand what can be causing this, i have read that a jog command and g code command to move come from different places. i dont understand what would cause the counter to remain zero if its not a software problem. by the time you read this ill probably be sitting in a corner fingerpainting, eating marshmallows and talking to bugs.
thanks for any and all help.
