Z Axis appears squashed Ultimaker 2 coverted to Ultimaker 2+

[michaelb123 0]

Hello, I have an Ultimaker 2 that was upgraded to the Ultimaker 2+.  I'm using Cura 3.0.4 and my z-axis appears to be squashed using the benchy print out.  I'm not sure what is wrong can anyone please help point me in the right direction.

Height should be around 48.00 mm, but I'm getting closer to 24.00 about half.

I did replace the heat bed on this unit at one point as well as upgrade the device from Ultimaker 2 to an Ultimaker 2+.  I'm curious if this is a cura setting or a cable backwords, etc?  Thanks,

Also, when a print finishes I get the following error.

Should I be using the Ultimaker 2 or Ultimaker 2+ firmware on this printer?  I currently updated it to the latest Ultimaker 2+ firmware, since the upgrade kit said the printer was now a Ultimaker 2+.  However, I'm now wondering if the firmware should really be a Ultimaker 2?

You have to upgrade to the "plus" firmware. There are twice as many steps/mm because of the 2:1 gear ratio. Plus I think it might turn the other way?

Also you have to do a factory reset to move the steps/mm setting from default firmware setting into the eeprom. Without a factory reset it tries to use all your previous values (including steps/mm on z axis).

Also it's possible you connected a fan cable to the Z 8/16 microsteps jumper. You want the jumper not connected - it's right in the middle of the board. Some people connect one of the fan cables to that by accident. If you look carefully it says something about 8 versus 16 microsteps for Z axis. And the fan cable is close enough to a short to make the stepper switch to 16 microsteps and hence move half as far.

Thank you so much gr5! The fan cable was indeed connected to the Z 8/16 microsteps jumper. I also needed to do redo the firmware update to Ultimaker 2+ and then perform a factory reset from Advanced's menu on the Ultimaker.

I remember when I was reassembly the cables that I wasn't sure which jumper the fan cable should connect. I guess, I just messed that up horribly. Anyway, thank you for the expert advice.

Did you get that Z error fixed? It's usually caused by something falling in the hole where the z limit switch is located. If you raise the bed by hand with power off and look under it there is a screw sticking down. That fits into a hole. Make sure that hole is clean.
