Hi Ultimaker Community! I have a short, easy question that everyone needs to know an answer to. Thanks for your time!

Hi Joris! Is it easy to change the filament on the printer? And is the cabinet air-tight? Thanks.

Hi @SandervG Yes, my friends made a flexible mold

The UMO uses an Arduino based Mainboard. For firmware questions, I will refer you to @lowiekvds He made the firmware changes, and is an Arduino expert! Welcome @lowiekvds to the Ultimaker community

There's no special reason (at least not that i'm aware of). AFAIK this are the standard formulas that Cura uses, if acceleration or jerk control is enabled. You can disable it in Cura, if you want. Mark2 works with the standard values of the printer as well. What's the reason of your question? Did you noticed any serious drawbacks related to these values? As you already know, we are building an UMO with Mark2 upgrade but we have a problem. The first thing I've checked were the Cura settings... But that's not the problem... Any other idea @tinkergnome?

I have also printed with the standard UM2 slicer settings, so that's not the problem... I mean that you check the firmware default accel/jerk settings. But indeed it’s weird Delfaut accel: 3000 and delfaut jerk: 20 So that's okay...

Thanks for your reply! Okay, good to know I will try the Gcode on my UM2E+... @tinkergnome Gcode works perfectly on UM2E+... So the problem is on the firmware side...

Thanks for your reply! Okay, good to know I will try the Gcode on my UM2E+...

Why are the acceleration and Jerk settings so low on the standard Mark2 profile?

I have also printed with the standard UM2 slicer settings, so that's not the problem...

Problem is not solved with slower speed...

Thanks for your reply! Here you have the Gcode. I will test it with the lower speed...

Normally Cura wil overwrite your current Cura files and wil keep your settings, profiles and printers. If you want to keep the 2 versions, you can copy the files in Programs > Cura > Contests > Resources > resources > map of the files you want to copy...

Hi, Do you have the newest Cura version? (2.6.2) You can download it here Pleas let me know if your problem is solved!
