USB / serial problems

Post by th7511 » Mon Jul 13, 2015 9:20 am

Hi,

I face a lot of serial communications errors ,
sometimes i have 5 minutes with no problems then too much errors (resend or wrong commands or n 'waiting commands) to use the printer
don't know what to do

i checked serial speed/stop bit/parity: 250000/1/no
cache size 63

i tested change of usb cables

any ideas?
