Moving part origin
« on: April 19, 2014, 06:25:28 PM »
Happy Easter everybody!

I have an Chinese made router, distributed by IEHK (www.iehk.net) that, a week or so ago, I converted from pendant controller RZ********* to mach3 control.
Just to mention, I'm an electronic guy so I made my own BOB (original pendant has differential outputs, so the BOB that I made is converting LPT port Step and Dir signals to differential ones).
Today, I started a job which is 350 x 450 mm and has 7 roughing passes and one finishing.
After tool change for a finishing pass I've noticed that my origin has moved approx 0.4 mm per pass, approx 3 mm in total, both in X and Y direction. Haven't been by machine all the time, but I guess that the move occurred after every pass.
Machine is servo driven with 2.2 kW water cooled spindle.
Could not figure what caused this moving of work origin.

Yesterday I made a simple code to "touch" 4 points 500 x 500 mm apart, repeating the process 50 times, and the tool made the touch points spot on :(
