Hello, when can we expect the new firmware for the M201 with the bugs fixed?
Please respect us, the clients that bought your product.

Thank you, this is all very helpful!
I recognize all the symptoms you mention.

One thing is, I tried to unscrew the nozzle but I noticed I was damaging the hexagon sides.
It is screwed on very tightly!

Would it be better to first heat up the hot end and then try to unscrew the nozzle?

This is no help at all.
I already tried version 1.0.3 which was released as v1.0.1.
It has errors, it is as simple as that.
When is it going to be fixed?

You are probably right.

Is there an instruction manual available how to do this for a 2-in-1-out hot end?
I am afraid that I will damage the hot end.
This is still a bit new for me.

I am using the m201 printer. I replaced the PLA filament on the left extruder. After the change there is a serious under extrusion problem. All surfaces are open. Furthermore the printer mixes the 2 filaments in the first 2 or 3 layers. But settings are for first filament 100% and second filament 0%...

yes, I use 115200 baud rate and a 63 bytes cache size.

Guys, I would appreciate it if you REALLY TEST the firmware before you release it! Installed it, tried printing from sdcard 3 times, every time printing stops after a few layers. Not a pause this time, it really stops. By the way, Firmware version in the menu says v1.0.3. I thought this was v1.0.1?

Here are some screenshots of issues with the new firmware: Cannot print from sd card. Printer starts reading and stops, but stays in printing mode. When you try to stop printing it hangs on message 'Print stopping...': http://certeza.nl/uploads/images/print_stopping.png When you print with PC via us...

Hmm, has anything been changed for the sd card?

After the update printing from sd card doesn't work anymore.
It starts and then it stops.
And when I give the command "Stop print" then it hangs on the message "Print stopping..."

Printing via usb works.

I can confirm this. I have exactly the same issues.
