Error: Wrong checksum

in Slic3r
I just got my trevo flash 3d printer, its secondhand but is supposed to work fine. I'm extremely confused as to why this is happening, i've been trying to print something and continue to get these logs non stop 

23:07:41.318 : Error:No Line Number with checksum, Last Line: 14
23:08:20.290 : Error:checksum mismatch, Last Line: 14
23:08:20.292 : Resend: 15
 
but it repeats over and over again

    Please activate ping-pong mode in serial settings first. This happens on communication errors. Either you are flooding with to much data (input buffer too big which ping pong prevents as it only sends one line and waits for ok) or your baudrate is wrong cauing many errors. Especially 230400 instead of 250000 can cause this easily.

    I've trouble shooted with that already with no luck :(

    You can try different usb cable or different usb port. Sometimes it helps. When settings are theoretically correct it is normally interference with something adding noise to communication. Does it get some lines done just many checksum errors or is it not working at all? The error messages come from printer so that direction seems to work.

    It doesn't start printing at all

    Do I need to configure the printer or somethint with an outside source or will this do that for me?

    null
    I tried this and it also didn't work unfortunately

    I also tried doing it through the server instead but that just kept popping up with error messages. It would say print time 4s and then just error message

    Did you select Marlin as firmware? I think that is what it is running. If it would use binary format for repetier-firmware it would not understand anything. If nothing works you need to print via sd card. Normally not needed but all typical reasons are now tested. Only thing that might show a bit more is a full log where it transitions from working to not working with all data send and received. Maybe it shows something not thought of.
