Cura firmware problem

Recommended Posts

Posted · Cura firmware problem

Hey!!

I am using what I think is the latest version of firmware for my UM2. I have been having retraction problems and tried to turn it off during a print. I set the retraction speed to 0. This caused the printer to lock up and I had to reboot it. Luckily the print was only 1 hour old. I tried other values for the speed and it did not lock up. I also tried putting 0 in the distance value which worked ok.

May I suggest changing the minimum value for speed to 1 instead of 0.

Thanks

If you put a speed of 0, the retraction will not move. So the printer will just sit and wait for it to finish forever.

It's like waiting for your car to back out of the driveway without starting it.
