Please..Help Axiom AR8

622 Views 8 Replies 5 Participants Last post by  Mic666
My X axis is failing to respond, Z and Y are fine. I have checked wiring on the side for loose connections, they seem good. When I Home All on UCCNC the software co-ordinates are moving on the PC but the AR8 is not. When the machine is on I am able to move X by hand which seems strange.The machine is approx 2 years old but only used as a hobby toy maybe 1 weekend in 4, havn't even worn out the bits that came with the machine.If anybody can point me in the right direction, it would be much appreciated, as I live in Australia and help is very scarce.

Thank you, at least we are from the same state.

That certainly sounds like either the stepper isn't getting power or the stepper is bad. Any chance you can switch cabling between X and Y to see if the same thing occurs with either Y not moving or being able to move Y by hand with power applied?

G'day @Mic666 , welcome to the forum.

So at least now you know the X stepper is good. I realize you checked the connections but is it possible to switch out the cables end to end to verify the cable is good?

Pull the side cover off of your machine (left side facing machine) and there should be a multi-pin connector for the motor and the wiring harness. Use a VOM to check continuity on the cable running from your board to the multi-pin connector at the motor end. If all is good then it sound like your board is bad. Hopefully you're not running a Rich Auto hand held setup like here in the states, as those units are all one piece inside the control box.

Thanks for the info,I think it's the board as I opened the control box and found 4 separate boards so I swapped the x and y axis and the x axis moved and y did not, so fingers crossed a new board will fix the issue.
