Ultimaker 2 to 2+ Feeder Spacer

thingiverse

This feeder spacer frame is needed if you want to fit the Chinese Ultimaker 2+ feeder to the Ultimaker 2, as the stepper shaft is too long on some Ultimaker 2's, so instead of cutting the shaft, which I think is a bad idea, you can use this spacer. You will also need the alloy mounting plate, and some m3 bolts, I cut my m3 bolts down with a dremel to get the correct lengths. Some feeder steppers on the UM2 do not have the D shaped shaft to fit the new plastic gear, you will need to file or grind a flat spot to fit the new gear. Set the tension on the feeder to about half way, this is done by turning the hex bolt on top Anti clockwise, like you're loosening it, but you're actually increasing the spring tension. Install Tinkergnome firmware using Cura, as you will need to change the feeder E steps to around 738, tinkergnome has a feeder calibration to extrude 100mm of filament. To do this you need to remove the bowden tube from the feeder and insert a piece of filament into the feeder until it's level with the top of the feeder, now extruder 100mm using Tinkergnome and measure how much you get, if you get 103mm, just take the number you desired which is 100 divided by 103 times the number the E steps it's set on... So I got 103mm, so 100/103 = 0.9078 * 738 = 716, so I set the E steps to 716, this now gives 100mm of filament Added the 3dsolex TFN couple, and the ultimaker 2 is printing very nice! Additional setup with Tinkergnome, PID Autotune your nozzle and heated bed, set the target temp to what you normally print at, this helps a lot. and do a bed level with a new install on Tinkergnome!!!
