I have recently purchased a '95 Arrow 500 with a CT FNC controller. Have had a few teething problems. Getting most of them sorted now.
There is this one thing the machine does that freaks me out a little.sometimes when you start it up, you press the green button, then press again and the Y axis comes shooting forward at rapid, so I hit the Estop. Now when I switch it on, I press the green button once and monitor the indicated positions, occasionally the Y is running all over the place which to me sounds like an encoder problem. I only press the button the second time now to energize the servos if the Y axis measurement is stable, whenever its unstable the table will take off.
Its not yet done any crazy moves when running, but I fear that could happen at any time, and it may be a problem that gets worse.
Has anyone seen this exact issue before??
Thanks
