Hello! This is a question related to my 3D printer so I’m sorry if it’s not within the scope of this forum.
I’ve tried Makerbot support but I’m not getting much help.
So far I’ve printed 32 of the MPCNC pieces with some occasional issues (I will explain them later) but the prints eventually worked after a couple attempts. I mostly have the longer prints left to do: C-Roller, C-Roller M, XY_C_Burly, Tool_Mount_C_6-32.
The first problem that I had early on was bed adhesion but I fixed it by increasing the number of external brims and lowering the speed + disabling the fan on the first layer. Changing from hexagonal to linear infill also helped with some other printer issues.
Now onto the 2nd, persistent issue.
It seems that on the longer prints it gets to a point where the filament begins to under-extrude.
Always happens at a different Z-height. Most of the time it’s after ~60% but has also happened earlier.
Makerbot Replicator 2 (enclosed)
Hatchbox 1.75mm PLA
Retraction distance: 1.3 mm
Print speed: Solid 90 mm/s | Sparse 80 mm/s | Shells 35 mm/s
Changes/inspections I’ve made but did not fix the problem:
- Was printing @ 230, decreased to 220, 210, and 205 with no improvement
- Checked hotend fan
- Replaced SD card
- Checked tension on filament
- Replaced nozzle + cleaned old one
- Re-sliced STLs
- The print speeds listed above used to be faster but I decreased them with no improvement
I really want to get this working but the last few days have been very frustrating. I’ve probably “wasted” over 500g of filament
Any advice for a beginner? Thanks so much everyone!
