Communication timeout - reset send buffer block?

Well my latest print was almost done and the machine just stopped and this was the error code I am getting any Ideas?

Did you update your computer to Windows 10 ?

Nope!

Can anyone help with this machine is still down???

Try disconnecting the Printer from USB and reboot.
Then reconnect.
Sounds like the Wondows com port driver hangs.

Does the printer connect in repetier?

What you can try then is go to device manager and show all hidden devices.
To enable that function you must set an Evironment variable :
DEVMGR_SHOW_NONPRESENT_DEVICES and set its value to 1
Then reboot and enable schow hidden devices in windows device manager.

After doing so, remove all serial port devices and uninstall their drivers, reboot and reinstall the drivers.

If that still doesn’t help your board may be faulty.

I am thinking my board is screwed so will have to send it off, gutted as I just got this bloody thing 3 prints and it poops out on me.

Would you have any idea on how to install a ramp 1.4?

Not happy Velleman!!!

Before you send your board in, try what i suggested.
Windows often gets in trouble with the USB com ports.

Did you try another PC yet?

What are cour settings in repetier -> printer settings -> connection?

here you have all settings under the Printer settings in Repetier-Host.

Your communication settings are incorrect.

Set them to :

Baudrate : 250000
Reset on Connect : disabled

then it should work

Thx that was the problem. :slight_smile: My bad. didn’t pay attention to the settings.

Nice to hear it works.
Happy printing!

Hi I am experiencing this same issue with
Communication timeout - reset send buffer block interrupting my prints but when I go into my printer settings in repetier I do not have the reset on connect option so may there be some other issue for me or am I missing something simple here? I’m running repetier 1.5.6.
My settings read as follows:
Connector: Serial connection
Port: COM4
Baud Rate: 250000
Transfer protocol: AutoDetect

Reset on emergency: Send emergency command and reconnect
Receive Cache Size: 127
Communication timeout: 40

your description sound like you are using down level software (0.84)
If this is true remove it and install this one 0.95F
http://www.k8200.eu/downloads/files/downloads/setup_repetierhost_k8200_0_95f.zip
You should be able to see all of the settings.
