New feeder

[3D4Makers 0]

I bought a Sanjui feeder because the orginal feeder of mine Ultimaker 2 is broken and now I need to change the E-steps but I cant figure out where..

I already tried it with Tinker gnome but the firmware keeps giving errors..

More information please.  Are you saying you were successful installing tinkergnome and successful setting the E steps/mm but then kept getting errors?

By the way you can use the original firmware but adjust the flow.  It's an ugly work around but it can get you printing for now.   Just move the filament by 100mm and measure how much it moves and then you now the percent error and can adjust the flow by that percentage.  you can do this in the TUNE menu once you start a print and before it actually starts printing (while it's heating up the bed).

Did you try version 16.01 here?

Thank you for your quick reply!

Succesfully installed the newest version of tinkergnome but when I started a print the printer gives me this error X or Y Switch Broken, but there is nothing wrong with the switches.

I just increased the flow and it gives me better results but I don't think this is the best way to do it..

"x or y switch broken" could happen during homing if you accidentally got the "um2go" firmware which has a smaller build volume. Or it's possible the dimensions of the printer got corrupted some other way - this is common when changing firmware versions. I recommend doing a "reset to factory settings" on the menu. This will probably fix the X/Y switch error.

Each firmware stores certain values in permanent memory such as steps/mm and print volume and about 20 other settings. Different versions of the firmware store values in different places. There is a mechanism where the firmware knows what the old firmware was and moves all the values to the new location but this mechanism only works when moving FORWARD in versions. If you go backwards (or sideways) it can get corrupt. "reset to factory settings" puts all those values (like steps/mm) back to default.
