So for the life of me I cannot figure out why this is happening. I can print small parts just fine say < 2hr prints, but i am having an issue with anything longer than this or with bigger prints and by bigger prints i mean x-idlers and what not. It seems that at the last few layers or 20 mins given the x-idler the y-axis starts shifting really bad about every 5-10 layers rendering a 4hr print useless “at my current settings”
Now before you go asking why an idler is taking 4 hrs to print, its because my y-carriage is to heavy for my 48oz/in stepper to handle at full speed / acceleration. I have the jerk settings way down, the speed and acceleration are at 1000 and 1500 respectively. Everything rides smoothly the belts are not to tight as far as I can tell. Not to mention its hard to diag since it only happens on “Large Prints”
I have fans on all of my steppers and they are cool to the touch when it skips like this, there are no teeth missing in the belts or pulleys, and I have filed a flat in the y-axis stepper. I still need to pull that off and see if it has skipped somehow.
any ideas or suggestions, what settings or fix’s have you employed when facing this issue.
The LM8UU side of this print is facing the back of my printer.
