I designed this bracket to attach the Dondolo dual extruder to my ORD Hadron. I have yet to test it on my machine, but the mounting holes are accurate and it should work. You may need to adjust your y-axis makerslide further forward because the extruder extends out from the x carriage further than a Wade's extruder does. See "Instructions" tab for tips. This is a drop-in replacement for the Prusa x-carriage, no other parts need to change for this component to allow mounting to the Hadron default carriage.CHECK YOUR NEW Z-AXIS ZERO POINT MANUALLY before running a homing procedure. Your head could crash if you do not take care to adjust your Z-axis zeroing height. Be aware that the extruder will now extend 35mm in the positive Y direction further than if using a Wade's extruder or other extruder centered on the mounting bolts on the Hadron carriage plate. Monitor the Dondolo for wiggling about the X-axis. It may be necessary to secure the top of the extruder to the X carriage plate to stop wiggling. This is due to the height of the heavy servo and stepper motor above the mounting screws.
