I have found an issue on the last batch of fadals that were built for auction( issue has been found on 2 machines now).I have found that the bolts holding the bracket under the table that the ballnut...

It is to the point that you should contact the factory and see if they will help you out, there may be a good reason that the rebuilds were done there and not in the field.I dont know anymore about...

I looked at the part list picture and there are set screws in there,it looks like the preload ring (rot-0035) is like a spithe nut where you set the load tightness and then the set screws strech the...

I never took one apart so i am not sure what the nut looks like or why the threads are there,possibly for some tool fadal made up,make sure there are no set screws in there.the only work we do in the...

If you have to loosen the nut that tightens the main shaft bearings be sure to not over tighten it.I would pull the motor off and feel the drive gear,the unit should turn freely by hand.then be sure...

I have no info on the rebuilding of the unit but i do have an exploded diagram and parts list.

the axis card reverse direction jumper is only for and axis set up for that,generaly used for left side mounting of the x motor.i am not sure about the a axis using it.if it works fine just backwards...

take the 4 off that you see pull the cover back and 4 more bolt it to the casting,they cant be seen until the cover is pulled back.

most likely you can fix this by taking the z motor off and putting the coupler i n a different position,when the machine was moved the z motor was probably taken off and when replaced the coupling...

There are only 4 screws holding the front cover to the saddle,take them off and pull the cover back, you will be able to get at the end of the screw.if you have to clamp something on the screw the...

The fadal replacement parts would be mtr-0155 for the 2-lobe derlin (I prefer these,rigid steel coupling w/derlin insert, less trouble).or the mtr-0189 4-lobe zero backlash type, these are clamp...

the battery is on the cpu slot#5 in the card cage.the battery is purple and is aa size it is soldered to the board you will need to cut it off and resolder the new one on (it is easy to do).the...

The buzzing sound coming from the air valve means it is going bad.the other one under the side cabinet was for an a axis rotary.if the valves are the same swap with the bad one.one of my customers...

Must trust bearings are packed with kluber grease,it is expensive but good high end grease that will last.most new bearings come prepacked with grease already in it.

you can jumper fuses f16 to f14 on the power distribution board to bypass the e-stop,the machine can not stop itself like this so be carefull.

you can download the manuals from fadalcnc.com

try swaping mill interface and clock cards with the other machine.check all signal wires going to the motherboard and power distribution boards.try leaving the rs232 cable unpluged from the...
