I am absolutely thrilled with the LowRider 2! Many kudos and thanks to Ryan and everyone who helps him!! Thank you!!!
My reason for this remixed LowRider2 “X2_plate.STL” is the “Saga of the Sagging Stepper Motor” (a couple of PLA parts failed due to heat).
My X-axis stepper motor was sagging down visibly. I could tell it was from the PLA deforming due to heat. This was confirmed when I took the assembly apart. Perhaps my control board / firmware is sending too much electric current, or perhaps on one of my earliest jobs, I was doing something not quite right, or somehow running the motor too hard. My “X2_plate.STL” and “X2_idler.STL” both deformed quite a bit due to heat from stepper motor. See attached pics.
So, instead of just reprinting the X2_plate.STL as it was, I decided to fix two very minor issues. I thickened the mounting flange that protrudes upward, making it 5mm thick. Also, about all my screw driver shafts were too thick to get down into where the screws needed driven (those deep holes down low on the part). So, I widened that corridor a bit.
Also, although I did print the remixed “X2_plate.STL” again in PLA (the black one seen in the pics), I soon decided to reprint both the “X2_plate.STL” and “X2_idler.STL” in PETG, as to minimize chances of having to bother with this again. However, it was very first time trying to print with PETG, and the first print suffered from lift and warping, and my second attempt revealed my printer's hot end was completely clogged. I have replaced the nozzle and cleared everything out and reinstalled the hot end, but have not yet tried another PETG print.
Whether I end up using PETG or going with PLA again, I'm hoping the extra thickness on the upper flange will help.
