* | * DO NOT USE Isopropyl Alcohol on the '''IPG Blue Tape'''. (On any other make of Blue Tape using that is fine.) | ||
* | * The wood support structure that holds the printbed is loose! At least on 1 side, a partial disassembly may be needed, to reverse which side the bolt heads are on, and which side the nuts are on. | ||
** '''FOR NOW:''' Grab both sides of the front '''wood''' structure (just outside the bed level screws), then gently move one side up, while the other moves down, to get the bed level. (Bed seems to stay level for printing once ajusted.) | |||
* | * The flatness of the used side of the '''3mm Carbon Fiber Plate''' is out by LESS than 0.1mm ... so large prints should again be possible on this printer. | ||
* '''If needed''', manually adjust the Z-axis for the first layer until the filament is being laid down flat (not rounded). | |||
** Turn the threaded rod clockwise to bring the head closer to the print bed, and counter-clockwise to move the head further away. | |||
* '''This printer is in fairly rough shape mechanically'''. This causes the most problems with prints that have thin filled walls. | |||
** Printing slower and at a higher flow rate can help with getting acceptable print quality. | ** Printing slower and at a higher flow rate can help with getting acceptable print quality. | ||

|Head was jammed, took it apart and replaced Hot End Isolator Coupler, Hot End Isolator Tube and PEEK Insulator with ebay parts that were in 3D printer parts bin. Seems OK now, maybe under-extruding a bit. | |||

* Using a feeler gauge & Machine Shop straight edge, determine that the center of the plate '''is high by more than 0.2mm'''. | |||
* HOWEVER, the other side has a different high/low spots pattern, that is out by '''less than 0.1mm'''. (More than 0.06mm, and less than 0.1mm) | |||
* So able to get the Carbon Fiber Plate working to print on, by ONLY using the '''one good side'''. | |||
** '''See the Known Issues and Fixes section, about the loose wood under-structure that holds the build plate.''' | |||

* 300mm X 200mm X 3mm Carbon Fiber Plate purchase for printing on is HIGH in the Center. | |||
* After installing (without cutting) takes HOURS to get the bed leveled. (Front left spring can't go up more. Back right level screw seems jammed.) | |||
* Once leveled, CAN finally print on entire print bed, but high center has print in that area toooo close, in a way that will always rip blue tape when taking the print off. | |||

* Reconnect the board cooling fan on the underside of this printer. (Wire pulled, so not plugged in?) | |||
* Use a straightened out coat-hanger to get badly broken out of the bowden tube. | |||
