Ender 3/32bit Board Marlin (CURA)

I have added one of the new MK2 systems to a buddy's machine. It was fast and honestly easy to install with a direct drive. Notwithstanding, I am confused with the setup though of the GCode.

The printer started fine, the instructions said to change a few lines, and the 3dChameleon was homing and changing tools correctly between extruders. However, when it started printing the skirt, it was about 5mm over the bed on its Z height, and the extruder was running at the speed of sound and just skipping like mad. I am using the profiles recommended by Bill and only updated the areas requested in the G-Code.

I printed before the installation of MK2 and made sure the Ender was printing correctly to rule out any issues in installing the system that could arise from a prior incorrect misconfiguration.

My question would be, how do I fix my Z Height and High-speed Extruder during the printing?

ALSO, I'M THE FIRST TO POST BOOYA!!!

Hi Ryan! Ok... our code doesn't actually do any Z motions, so I'm not sure where that is coming from. However, I noticed that you're using a little older version of our software installation method than I recommend. For Cura (and all our supported slicers) you should start out with a profile that is known good and working for you without any modifications (for our stuff, that is.) So for example, Cura has great profiles for the Ender series of printers. Make sure you can print with it, then up the extruder count to 4, (making sure to copy all the settings from extruder #1 to the other 3 new ones) and then use our GCode Generator to create the 8 (4 for other slicers) blocks of gcode to copy into the Tool Change portion. We do not require any start or end gcode modifications for Cura, so the default settings will be maintained, and as long as the existing code doesn't show that symptom, you should see the same correct behavior after our code is added.

OK, That totally makes sense, and I was reading the G-Code to the best of my ability and couldn't see you modifying really anything but tool changing but with CURA 4.10.0, it was so weird. I didn't change anything except installing CURA 4.10.0, and this computer had no previous installs of any slicer and download/import your profile.

Cura did not work as I expected, even though I'm fairly familiar with the software.

I did, however, install the latest PrusaSlicr and the same thing just imported your profile from online, and boom! It worked, no problem!!! I have some measurements that I got wrong that need to be adjusted for the tool changing G-Code, but that was my own doing. It printed perfectly, and I am thrilled!

I have heard that S3D (Simplify 3D) and CURA have some issues, as does Prusa, I'm sure, but, for whatever reason, PrusaSlicr worked without a bunch of work. It took me about 5 minutes, and I started printing. I have S3D, and it did work with a little more effort, but to keep costs down, I doubt everyone would jump to S3D except those who own and swear by it. I'd say PrusaSlicr right now is the easiest to use for printing in color.

Bill, Thank you for such a quick response. Also, thank you for this forum where we can gather your knowledge and ours to assist everyone looking into and owning anything to ColorPrint. I assume it will be helpful no matter what product is used.
