Material Feed is reversed

[undertherain 0]

Hi I haver just updated my Ultimaker 2 to the 2+ using the upgrade kit and everything went well however when I try to feed filament the motor direction is reversed. I have seen several other people on the forum with the same issue but no real solution does anyone know how to fix this. I have installed the printer as both U2 and U2+ and upgrade both times to the latest firmware and its still the same. I have the latest cura also. Are the motors in the kits wired incorrectly? or is this a firmware issue? If anyone could help I would greatly appreciate it as after a £400 upgrade my machine is no longer working.

 

Thanks

Hi undertherain,

 

If you just upgrade from "the real UM2" to the UM2+, without all the changes needed, you might have a reveres feeder as a result (plus feeding much to fast).

 

The thing is; an upgrade to UM2+, also ask for a new feeder installation. Yes, you have to change the whole feeder unit into a new one that is rotating the other direction. There is also a different speed for the feeder as this also will feed very much to fast(to much feed)..

 You need to change the feeder unit with the one needed for this software change, or you have to change the number of feeding steps and the direction of feeder back to revert back to standard UM2 settings.

 

Thanks

It's fixed now thanks for your suggestion. I spoke to tech support on the phone Cura 3.4.1. has a bug with updating firmware downgrading to 3.4.0 and re-flashing cures the issue.

 

Many Thanks
