CR-10S - Enclosure

The Enclosure

So here we are looking at the limitations of PLA for making RC Model aircraft. The main concern is the low temperature resistance. HIPS seems to be an interesting material with even more stiffness than PLA and much greater heat resistance. Unfortunately, like ABS, HIPS requires a very hot bed and an enclosure.

The first thing I did was to make a frame big enough to hold the printer. I didn't include the control box in the enclosure because the control box needs to be kept as cool as possible.





Once the frame was completed I covered the top, left, right and back sides with Reflectix an insulation material I got from Lowe's.
I used 3M metallic tape (3M 3340) to secure the material to the PVC pipes. This tape is rated to withstand temperatures -40°F (-40°C) to 300°F (149°C) 


We left the bottom uncovered and only covered the front partially. The opening was covered using transparent plastic (Optix). We used the same tape to make a hinge one one side.


On the other side we used a magnet to keep the door closed. The door is not airtight but it will stay closed.


On the side were the control box sits we cut a narrow strip for the filament to go into the enclosure.

Finally we added a light. We attached a small lamp, the kind indented to be installed under the cabinets. We secured to the inside of the box using 3M tape.



This enclosure should be sufficient to keep the air inside stable to print HIPS and ABS. Hopefully it will help keep the heated bed to the required 120ºC.

Eclipson Model-Y - 01 to 03

Eclipson Model-Y 01 to 03 Downloaded the Wing_C.stl Print attempt 01 Loaded Cura 3.2.1 using the standard settings for the CR-10 Modified the following settings: Profile: Fine Layer Height: 0.2 Wall Thickness: 0.4 Top/Bottom Thickness: 0 Infill Density: 0 Enable Retraction:  Checked Retraction Distance: 5mm Saved file to SD Leveled bed CR-10 Put painter tape on CR-10 Used Glue-Stick on print area Started the print the normal way. Monitored the first layers closely to ensure there were no issues. Noticed some minor imperfections on the trailing side but didn't think they were important. Significant issues started to appear 50mm up. the stringing on was very significant on a a nozzle travel path.  This problem was to important to ignore and I stoped the print. Closer examination of the part and the Cura layer view confirmed that the stringing happened on the nozzle travel path. Further examination of the part revealed

CR-10S - Extruder troubles

Image
Extruder trouble The simple 30-minute build of the CR-10S had turned into a multi-day event. We have resolved several unexpected issues: Couldn't screw the gantry to the table because the wholes didn't align. Solution: Move the x-axis in the gantry all the way to the top. Then attempt to screw it. Stripping the treads in the z-coupler. Solution: use a bigger screw. X-axis not leveled. Unable to "Auto-Home". Solution: find the way to adjust the x-axis angle with respect to the z-axis. At this moment we felt ready to attempt our first print. Loaded the extruder tube with filament. Pushed some of it in and it came out melted as a 0.4 millimeter hot plastic noodle. All ready to go. Pick our first print from the SD-Card and go for it. NOTHING. The nozzle head moved around but no filament was coming out. Nothing. The extruder seemed to move but not knowing how it was supposed to move I was at a loss. More internet searches and questions asked. Final
