Still very happy with my K8200. Have been quietly printing and upgrading/tweaking for the last couple of months, and having great fun.
I have just this week, completed this project thingiverse.com/thing:724999 I experimented printing parts in PLA, ABS, Taulman’s Alloy 910 and Tech-G, and just recently Eastman’s Amphora 3D Polymer, and Polymaker’s Poly Max. It’s really astonishing just how strong parts printed in some of the more exotic filaments can be!
But I digress. As per the title, I have a small and annoying problem that I cannot seem to figure out! I have layer shift/miss alignment, but only on one axis. I have tried may things to eliminate this, but so far I have had only managed to minimize it. Please see pictures below for better understanding.
As you can see, great results in one axis, not so great the other.
Upgrades as follows. Z axis upgrade, TR12X3 trapezoidal lead screw with brass nut, gt2 belts, custom tensioner assemblies and 16 tooth pulleys on x and y axis, DV8825 stepper drivers with heat sinks and active cooling, 24v upgrade to heated bed and 24v E3D v6 hotend.
I have gone over the printer with a fine tooth comb and checked every bolt, screw, fastener, checked voltages for drivers, checked the linear slides and bearings, belts, wiring. Please can someone give me some sage like advise? I am running out of ideas.
The only thing I am yet to check, that is kinda weird, is one stepper (x axis) is virtually silent in operation, the other (y axis) is noticeably noisier. I have been thinking about swapping the steppers (x to y) to see if the miss alignment follows the stepper. Might do this soon.
I’m open to any suggestions, please help before my head explodes!
