Description

The Creality CR-10S V1 is a cartesian 3d printer with a relatively large build volume. It is built primarily using 4040 and 4080 extruded aluminum with the beams running on the X axis being constructed of 4040 aluminum and all other beams being constructed of 4080 aluminum. The axes on the CR-10S are constructed using shielded bearings and acetal running wheels which provide maintenance free operation. The axes are constructed in a Prusa format with the Y axis moving the build plate, the X axis moving the extruder, and the Z axis moving the X axis carriage.

Firmware

The 3d printer was configured using the configuration file example found in Creality/CR-10S/CrealityV1 and Marlin version 2.0.9.5. Future changes may include adding more bed leveling points and an upgrade to the latest version of Marlin. Additionally, the leveling grid may start from the previously recorded leveling point instead of starting at a 0.2mm offset.

History

The Creality-CR10S was donated by Kyle. Thanks.

The glass build bed was donated by Michael.

Hotend

The hotend was previously clogged with a giant blob of PLA. Please watch your prints through the first layer at least. Not all prints will succeed, but you are more likely to succeed after the first layer is printed.

The thermistor on the hotend was replaced on 2022-07-20. Problems were noted in June.

Bed

The build surface was blue tape when the printer was first donated. The build surface was the Creality "Carborundum" tempered glass bed. As of 2022-08-22, the bed is binder-clipped, PEI coated steel.

Controller

The mini USB B connector on the controller board was previously destroyed. The printer is now connected to octoprint using a hardwired USB A cable. Thanks Yangbot.

Operators' Log

Bed adhesion issues noted when printing bike handlebar spacers.

2022-08-28 Brandon

Bed adhesion issues confirmed.

Bed leveling was completed successfully, but there is a significant dip in the center and center, right side of the 3d printer bed. Bed leveling shows concerning data:

0.2mm leveling data
0.225	0.225	0.275
0.225	-0.050	0.000
0.275	0.250	0.300

Nozzle was severely clogged with burnt plastic. Nozzle replaced.

The clogged nozzle could have caused the issues on 2022-08-26, but a bed leveling was also performed. Additionally, extrusion on the first layer is increased to 120%.

2022-09-03 Brandon

Bed leveling completed and bike handlebar adapter from Thingiverse successfully printed.

The bed is still severely unlevel in the middle and center-right corner.

In order to adhere to the rough PEI surface, the printer was leveled 0.1mm lower than the measured height. This is done so that the first layer of extruded plastic will flow around the rough PEI coated texture on the bed and create a stable mechanical bond.

USB port broken during printer shuffling and repaired/replaced by the yangbot.

Although it was once an issue, it is no longer an issue. Do not place stress onto the USB connector and always check the print area for things that may come into contact with the printer while it is in motion.

The last print performed yesterday at 2022-12-05 23:50 did not succeed. The filament was not loaded during the print, and a first-layer inspection was not completed.

Nozzle is further from the printer platform than normal. This may be the result of a previous maintenance action on the 3d printer or from a previous operator failing to save the printer bed leveling data into EEPROM.

The issues were resolved by turning bed leveling on before starting the print. m420 s1 applies bed leveling and should be run after the printer homes axes.

Previous operator logs did not note other dips in the 3d printer surface between the center and rearmost leveling points. It is theorized that a more granular UBL grid would be able to compensate for these points in the future.

The fan was replaced with the Y.S. Tech YW04010012BSS previously selected for the Zortrax. Although the printer probably works, it is now placed into delta stale status since a minor qualification print with the new fan is required.

Possible hazards during the delta stale qualification print include nozzle undertemperature and failure during initial hotend heating.
