Y axis problem on Ultimaker 2+

[Objectprint 0]

Good afternoon to you all,

So let me introduce my problem.

A few weeks ago, we did a firmware update for our UM2+. Since that date, all the problems started to arrive.

For every print and even buildplate calibrate, the dimensions of the Y axis are divided by two. The X and Z are ok for the dimensions and speed.

The printer used the same quantity of material as if the Y axis were "full scale", the part is all squeezed in the Y direction.

So after checking the web, i did severals things:

- Check all the belts and pulleys, and tightened everything.

- Check all the plugs connected to the electronic board

- Modify the set-up of Cura for this printer (mainly the size of the table in Y direction)

- Put all the firmware for UM2+ started with 14.04 until the last one

- I did not made any change to the firmware using Marlin or Arduino

Despite all those check-up, i still have my problem.

And the LED is not working, but this my least problem.

Actually, i am really stuck and i don't know what to do.

If someone can help me, it will be great.

Thank you

Are you 100% sure that you did choose the correct firmware?

Cura 14.04 doesn't have Firmware for UM2+

Hello,

I take Cura 14.04, and the option update firmware for UM2+ was available. So i thought it was ok.

Otherwise, i try to change firmware from 14.04 up to the last one (Cura 2.1 and something).

14.04 have UMO+ but not UM2+. Can you double check it again?

i think he means 15.04..

after a firmware update, i would always do a complete factory reset.. it will clear any wrong eeprom settings. can you do a factory reset and let us know if this resolves it?

Oops, my bad, it was actually Cura 15.04.

And i did a factory reset after each update of firmware. And it didn't change nothing.

Can you try with the firmware on the latest cura 2.3 beta?

I just did the update with cura 2.3Beta, and then a factory reset.

And no change with my problem.

Small update: after using Printrun, i managed to modify the M92 line (for step unit on each axis). And now everything to works, UM2+ is printing a test part and everything seems ok.

Thanks for your help
