This one has me stumped When I try to use the touch probe on first touching the probe to the router I get a spark and a fault comes up on the Y access i have checked all connections nothing appears pinched or loose. There is 17 volts present between the case of the onefinity controller and the act…

After much unpluging and pluging including swapping cables The only way to reove the voltage is to remove the Y2 cable from the machine (y right side motor) The socket in the end of the right rail has 4 connectors in it the top right one has continuity with the rails so i am assuming a fault in th…

Pretty sure the Y socket should not have continuity with the rail!

That was my thought, not sure if Onefinity monitor the forum or weather to drop the a line

Hey Jim, hey @CSM Darren, [image] Pleased2fly: pretty sure the Y socket should not have continuity with the rail! yes, I agree , Darren, you did not answer my question: If, with multimeter connected between the case of the Onefinity Controller and the rails of the machine, and you see the …

Hi sorry I connected a wire from the machine to a know good earth point when i swicted the machine on a Y motor fault appeared on the screen and i could reset the stop or cancel the fault i then powered down before removing the temp ground wire I am convinced that the fault is in the right Y rail …

[image] CSM: I am convinced that the fault is in the right Y rail internal cable or motor or socket which fills me with dread as i assume its a machine strip down job Yes I agree. There should not be a connection between a motor driving conductor and the rail. And without this fault, you sho…

you may proceed with error diagnosis by disconnecting the stepper, but I’m sure it’s the cable or the connector of the cable. As I think I already stated earlier, these tin-plated Molex/Amphenol Connectors used on the Onefinity are the first thing I will throw away when I will receive the machine a…

I bet one of the lines got pinched inside the steel tube, or the plug hidden in the middle of the tube is the cause. I replaced all those wires with a continuous run of IGUS CF6 shielded cable.

All sorted there was a short between the right Y rail motor cable and the machine body Replacement cable on its way from Onefinity
