turn the lead screws by hand, when the machine is turned on, there should be no play

hi Oleg, you need to rotate the screw itself by hand, otherwise you won’t see anything, it’s these clutches that burst easily, it’s better to replace them with those on the right in my photoVID_20230108_141504.mp4

So how can I replace the bearing? Will I be able to knock it out and push back by myself?

this is not a bearing, turn the screw, see if the coupling has burst, there are screws on it, loosen, remove the engine and replaceVID_20230108_151254.mp4

the motor rotates easily by hand, it is worth increasing the holding current
I said on the video that first of all I switched the motor and coupling X-Y to check if it's one of them. the coupling is fine

ок, clicks during movement can still be emitted by a screw coupling in the middle of the screw, if there is no lubrication in it, then when the washer is loosened, the balls can jump and click

is that your У axis? check everything already, you don’t need to remove it, just turn the screws with your hands, the damage is visible, if you don’t find any defects, calibrate the axes again

I also finished the molds. First experience, not perfect, but will see how the casting will go. Being a novice, I did the molds too tick, so had to cut away the excessive material from all the sides, otherwise would not be able to cut the mold into 2 halves.
Now just need to cover with graphite powder
