2 questions:
1.how tight is tight when adjusting belts on printer? almost stretched to breaking or just enough tension to "boing" slightly?
i found all types of info online but they go all over the place from just pull tight with hands and tighten to tightening so it has a certain pitch when plucking it.
i have tried to adjust belt to where it is slightly tight but i am still getting a vibe in prints and i don't want to cause damage getting too tight. i have gone through and tightened all the motor and frame bolts. i can slightly notice when the Y axis moves it make a low grinding noise, especially at lower speed for first layer and not as bad when speeds up. i adjusted current to where the motor sounds quiet but was under adjusted. i upped the current until noise was gone from motor but now it seems to come from the bed movement.
also my x axis keep getting slack in belt after adjusting. do the belts stretch and if so, how often to change? i have only had this machine about 2 months but have already gone through 4 spools. machine has been almost non-stop. is that possible for belt to stretch using it so much already. i've been looking at revised belt holders thinking it is slipping
2. while printer setting idle and heating up, not printing. my extruder will periodically extrude short bursts. is that a setting in firmware i need to look at or is that another issue and how to look into it. could not find anything online other that calibrating and that not an issue
my prints are coming out so awesome and within .17 to .23 of actual dimensions. i know that can be a belt issue but i have left default setting in firmware also without fine tuning. my prints are not that critical to be 100% accurate, but the oversize is close enough for me.

any pointers in right direction is appreciated
