Hi all,
I have been using a TouchDRO board, with 2 iGageing scale on my mill for some time and they have functioned perfectly.
I recently added a 3rd scale (all 3 scales were bought at the same time and are identical, except for their length - I've only just made the mounting hardware for the 3rd scale).
I am seeing large, sporadic jumps in the reading on this new axis. For example, if I zero the readout, within a few seconds, it jumps 4 or 5mm in either direction. The amount of the jump seems consistent between Zeros...ie, if it jumps +4mm, it can jump back to zero, or up to plus 8mm. If I then re-zero, it will jump by a different amount. This is with or without any ambient electrical interference...
The scales have all had their original cables replaced with shielded cables.
I don't know if this is significant, but the affected scale/readout is connected to the x-axis on the board, even though it is z-axis on the mill itself.
I plan to try a different channel on the board (w), but I thought I'd ask here too, just incase there was a definitive 'fix' for this behaviour..?
Cheers
Paul
