Glass Bumper MP Mini Delta

thingiverse

Three of these bumpers hold the 120mm glass and build plate firmly in place on a Monoprice Mini Delta printer. The bumpers keep the bed from shifting horizontally, ensuring a stable printing surface. Scale your prints to fit the bed size - for example, a 64mm wide part printed perfectly at 62.5mm on my MP Mini Delta. To fix the MP Mini Delta's sizing issue, I used G-codes M92 to adjust the XY&Z stepper values and then saved the changes with M500. This allowed me to print a 64mm model accurately. The original settings had 56.5 steps per mm, but I increased it to 57.6 steps per mm. Before achieving decent first-layer prints, I also needed to adjust the end stops by about .1mm. Next, I calibrated the extrusion system because 100mm of filament was only producing 96mm of actual extrusion. To verify the changes, I used M503 to view the updated settings.
