I last used my printer a few days ago, everything worked fine. But when I want to used it today, it doens’t react, in repetier host, it’s “connected” but I can’t see the temperatures, I can’t move the bed or extruder,… It says there are 5 commands waiting, but nothing happens.
I use repetier host V1.0.3, I tried reinstalling the drivers, checked the port, the Baud rate, tried resetting the printer with the button on the board, but nothing helps…
It should not have changed but is worth a look
In the printer setting make sure the baud rate is set to 250000
Make sure “Rest on Connect” is set to Disabled
Already checked those, they are still the same 
USB cable issue? Are you using a USB extension cord?
Did you try on a different PC to rule out PC problem?
I use the USB cable that was included with the printer, haven’t tried another PC though, but I doubt that’s the problem since I haven’t changed any settings.
The problem has been solved, my power supply had a bad connection, I fixed it and everything seems okay now. Thanks for the help guys
