Machine Log
| Date | Notes | Entry By |
|---|---|---|
| June 8, 2013 | Added tool holder onto side of Ultimaker | Norm |
| May 14, 2013 | Tensioned X/Y belts, switched to white PLA and tested new experimental settings. Readjusted Z bed height, printed stuff. | Norm |
| May 11, 2013 | Rod endcaps removed, threadlock (blue) applied to the M3 screws and setscrews locked into place to prevent loosening. Lubricated Z axis and gantry system. |
Norm |
| May 1, 2013 | Printed and mounted new Z home switch retaining mechanism and calibrated. Z homing much more accurate. Observed further inconsistent extrusion, further investigation found online that the knurled bolt is only useful for the last 3 mm nearest the groove for the delrin clip. Adjusted bolt positioning to move good knurling into position, no further grinding or slipping observed, consistent solid extrusion demonstrated. |
Norm |
| April 30, 2013 | Installed new e-panel composite based build platform. | Geordie |
| April 29, 2013 | Printed and installed new extruder feed gear to reduce backlash during retraction. Observed inconsistent extrusion. Small gaps appearing in extrusion, yet full infill occurring on layers otherwise (ie: not clogged). |
Norm |
| April 27, 2013 | Print quality degraded significantly mid-print. Hot end disassembled, burnt PLA removed from brass tube, and dust/dirt removed from teflon-PEEK interface. Print quality returned to normal. Clogged again, cleaned more thoroughly this time. (Used 1/8" drill bit to handheld scrape out burnt PLA very carefully. PLA diameter changed. |
Norm |
| April 24, 2013 | Squeaking noise observed from Y axis axle. Endcap inset screw noticed to be loose, requires new endcap to be printed, and screw not to be overtightened. |
Norm |
| April 12, 2013 | Bed leveling assist tool printed and built. | Norm |
| April 8, 2013 | Belts retensioned, new bearing endcaps installed to reduce backlash further. | Norm |
| April 6, 2013 | Z axis calibration fixed, Z steps/mm in new profile on Git. X/Y axis backlash observed, infill not meeting walls, delamination observed. |
Norm |
| March 31, 2013 | Z axis calibration issues observed. 25mm Test cube showed ~6.8% Z axis error. |
