Fallo en codigo impresora 3D

Buenos dias, he construido una impresora 3D DIY, que funciona razonablemente bien. El problema es que al activar el controlador de la ranura SD (para hacerla independiente) me da un error de compilación. He intentado contactar con el creador del diseño varias veces y no me contesta. Yo no se nada de programar y no se solucionarlo por mi mismo.
la impresora lleva un arduino mega2560 r3 original, un ramps 1.4, drivers a4988 y una “pantalla” riprapdiscount
Adjunto foto del error que me da el marlin, creo que es de sintaxis pero mi ignorancia me impide arreglarlo.
Muchas gracias por su ayuda


Good morning, I have built a DIY 3D printer, which works reasonably well. The problem is that when activating the controller of the SD slot (to make it independent) it gives me a compilation error. I have tried to contact the creator of the design several times and he does not answer me. I don’t know anything about programming and I don’t know how to fix it myself.
the printer has an original arduino mega2560 r3, a 1.4 ramps, a4988 drivers and a riprapdiscount “display”
Attached photo of the error that marlin gives me, I think it is syntax but my ignorance prevents me from fixing it.
Thank you very much for your help
