Creality CR-10

• Stock CR-10 S4, a little over a year old, well used
• When I got the machine, the bed moved smoothly by hand with a little resistance
• A month ago, it suddenly it became harder to move the bed
• Takes 2 hands to move, not smooth anymore, almost jerky once it starts moving, but it still printed fine
• Now the y-axis will lock up during a print, X and Z continue to work. You don't want to see the picures
• Restarting the machine restores the y-axis and the machine homes correctly
• With the machine shutdown, still hard to move the bed
• Removed the y-axis cable, still hard to move
• Removed the y-axis belt, bed moves sooth as silk, does not appear to be any flat or over tightened rollers
• Removed the y-axis stepper,
  • It is not difficult to rotate, it spins like a stepper should, with a stepped rotation
  • But randomly you feel a snap/click, once or twice during a full rotation, never in the same spot
• Am I correct in assuming this is a failed y-axis stepper?

After replacing just about everything on my CR-10S PRO except the motherboard, I went ahead and bit the bullet and purchased a new board. Due to COVID and stocking issues, I was just now able to install it.....and nothing. The fans come on, but the LCD screen is blank and Cura doesn't recognize that there is a printer attached. I'm pretty sure it was supposed to come with Creality stock firmware, is it possible that I have a bad replacement?

Hello again!!

So, a week ago I started having problems when printing with TPU. After and hour of so of printing, "temp runout" error showed up on the screen. After that I checked for the all hotend (e3d V6) connections, like thermistor, tightening heatsink to the nozzle and all that. Nothing was loose. The problem was still there.
After some more research I tried replacing the thermistor (original that came with CR10s). Now the error that came up was MINTEMP. It didn't even read the room temp. Heatbed works fine.
I checked the board, nothing looks loose or damaged.

Do you have any ideas what this might be? Thanks in advance for your input!!
