Printer: Geeetech i3 Pro C Dual Extruder
Mods/additions: Heat sink on Y motor, air funnel across ramps drivers, filament guide.
Firmware: Marlin ( I don't know what version)
Software for slicing: Cura 15.04
Method of printing: Octoprint
Problem: When printing a dual extrusion name plate the print shifts on the Y axis 6.87 mm.
Attempts to repair issue:
1. I read that the stepper might be getting to hot and added a heat sink and monitored the temperature by touch. I stayed room temperature.
2. I thought the filament might be getting caught on the lcd and added a guide.
3. I also read that the stepper driver on the RAMPS might be getting too hot and added a shroud that funnels the air from the RAMPS cooling fan across the drivers.
Each time the shift has occurred, it was at the same layer and shifted by the same amount. I have looked at the layer view in Cura, but I don't see the shift there. I haven't had any problems printing anything else.

Any assistance with this would be awesome.
