That's the problem. Nothing happens when the RM1 switch is pressed. It used to go into manual mode but now it does not reset anything. The machine doesn't do anything when the switch is pressed. I'm checking the limit switch in 30 mins so hopefully I'll have it sorted!

Did you get rid of these after or do you still have them?

Does anyone happen to know the location of the trip on the motor control board?

Thank you so much Marcus. You've been such a great help to a complete novice! I will check all of these things and get back to you. I hope it's something simple!

Hi, I have no movement at all. There is a reset button on the bottom right at the front. Next to that more in the middle is the axis L.S OVERIDE button. So should I be pressing this button whilst trying to move the axis? Any idea why the emergency stop doesn't put the machine into manual mode?

Power board repaired

I have repaired the power board by the drivers as there were faulty components (electrolytic and paper caps) The inputs to the motor are all reading 158v.
I've looked through all the schematics but I'm at a bit of a loss now.

Hi guys. I hope you help. I have sold my dad's Orac which on the day of sale decided it wasn't going to work any more! The spindle, x and z axis no longer move in any mode. The emergency stop button no longer puts the machine in manual mode (instead the axis L.S OVERIDE does) The guy who has paid fo...
