As you can see from picture the strands are not next to each other. I don't know what setting to adjust.

This is foot of the Ultimaker robot. Slicer is Cura, PLA at 210. layer .2, nozzle .4 speed 50. I am using an Olson setup and a Bondtech QR extruder. I did download and install the current firmware from Bondtech. this is a very consistent problem so I am hoping it is a setting

    That looks like "Bottom/Top thickness" in Cura is set to 0. The perimeter prints well, but everything else looks like infill.

    @chuck-yanke Maybe check that setting and make it 1.0 if it's on 0

    ...and you have changed the steps/mm for the e axis? (that's important)

    Here are the rest of the Cura settings

    I downloaded the firmware hex file from BondTech for the Ultimaker2 and installed it. I did not change or adjust any of the steps. My understanding was the steps had already been adjusted.

    yes you are correct I have just fitted the Bondtech I use S3D and it is fine (ish) I was under the impression the Hex File was moded already from TinkerGnomes Firmware.

    You can change to mm/s on the preferences of s3d if it helps.

    You appear to be getting very consistent 50% underextrusion. I think your steps/mm is off by 2X. Try setting flow in tune menu to 200% instead of 100%. Is it possible that you have UM2 firmware inside your UM2+? Is this printer new? Is this your UM2 or your UM2+?

    Anyway you clearly have massive underextrusion. If it's not your steps/mm then there's lots of other possibilities.

    Nope.

    I thought this is explained in the bondtech manual...?

    The setting is stored in the printers EEPROM. You can do a factory reset, or "print" the short gcode script from the bondtech website.

    I don't know exactly the changes from bondtech, AFAIK the rotation direction is reversed and the default steps/mm for the e-axis are changed to 492.45 (for the Bondtech QR).

    Usually the default values from a new firmware are only used if there are no settings stored in the EEPROM or after a factory reset.

    Glad you got it sorted don't know why you had the problems, when you set the steps how did you do it. Just so I know, I'm going to upload tinkGnomes latest firmware and set steps/mm

    I haven't checked my steps/mm yet but I believe it should be 564.  The UM2, UM2go, UM2ext all have 282 steps and doubling that gets you to 564 for the "plus" kit.

    I'm thinking though that the "plus" moves the feeder stepper the opposite direction!  Not sure if you can change that in tinker Marlin or not.

    tinker marlin is here:

    github.com/TinkerGnome/Ultimaker2Marlin/releases

    edit: Holy $h!7!  Tinker Marlin already has a "plus" version!  Use that one!

    Um2+ it's 360-390 or so. Um2+ uses other feeder motor brand and model with 1.8 200 steps/rev instead of the um2 0.9 400 steps/rev

    Edit: um2+ echo: M92 X80.00 Y80.00 Z200.00 E369.00
