Xc540 error

Thats a shame. Was the motor you fitted an OEM one or one of the chinese copies? They copies don't always work as well as they should!
It could be to do with the pinch sensor to the right of the head. Maybe the printer isn't registering the head is there properly on startup. Other than that its probably time to start changing boards

Chinese motor but doing the same thing it did with the original.
Not really sure what pinch sensor you are referring to, the one that senses the pinch rollers lever is in the locked position or the the little metal knob type thing that the head carriage locks on? Not sure what boards would need swapping, but hopefully it doesn't need any more boards swapped or repaired.

The little knob is just a knob, it doesn't have any sensing. I'm not that familiar with the layout of the XC, but there should also be a sensor on the right hand side that senses when the print head is in the docked position. It will look something like this ( the black part ). This is so the printer knows when the head has reached the far right position so it doesn't keep trying to move it once it gets there and cuts the power to the motor. It is normally around the same area as the end of the encoder strip

I think i found the sensor you are referring to, the metal tab on the head carriage pushes into it when it locks onto the metal knob. It is dirty so I'll clean it and see if that helps at all first.
I did try and turn it on yesterday and put a little pressure on the head carriage as if I was going to move it to the opposite end. Just that little bit of pressure moved it from processing to cleaning and brought me to the home screen with no error. Did not let me setup roll without the error coming back though. Brings me back to your previous idea that the head carriage may not be unlocking for some reason.

Cleaning it did no good, wonder if maybe I ruined the encoder strip when installing and should try the other since it was a 2 pack. Doubt that will fix it but might be worth a shot.
It's worth trying, but it is very unusual to ruin an encoder strip when installing. Even if it was damaged in the middle, the printer would still read up to the damaged point ok.
Also cleaning a sensor wouldn't help if the actual sensor itself is faulty, or if there is a problem with the board the sensor is connecting to

It could be one of the ICs that can't be replaced. These are custom made for Roland, and there isn't really an easy way to test them unfortunately. Even the Roland official technicians don't do board level work, they just replace them and see if it fixes the problem.
It could even be something like a bad cable connection inside the printer somewhere. I worked on one not so long ago that was giving sensor problems. I tested the sensor out of the printer and it was fine. Tried fitting a new sensor and that didn't work. Eventually took apart more of it and found out a mouse had been nesting inside it ( must have been nice and warm in the night ) and had nibbled through one of the sensor cables !

I checked it out again no bad ribbon cables or chewed up wires etc. I tested it and saw no issues. Turned it on with board exposed both led 1&2 stay lit up and green the whole startup process. This time it did not do a clean cycle and immediately gave the service call. I'm not sure but I wouldn't think board at this point and don't have the funds to just swap a servo board right now anyway. I'll try and switch back to the old motor and see if maybe with the new sensors and encoder strip maybe it will magically work.
Its worth a try just in case the new motor is faulty, it has been known. One other thing I would try is giving the bearing blocks on the back of the print head a good lubrication. If they get sticky it could be the head is sticking in the start position and that is causing the error. The head should move smoothly and easily from the head dock right to the other side and back.
I have encountered this before on printers that have been out of use for quite a while. The motor isn't strong enough to move the head, so it gives the scan motor error
