Mecreator2 raiser feet
Description
Nothing is more frustrating that a 4 hours print which is stopping before the end, due to a poor cooling design. Don't get me wrong : I love my Mecreator2 but my god, the design is terrible! It can go from not starting(when I unboxed it) to 150% of it's maximum speed(this winter, in the garage with an ambient temperature below 10°C) Why am I keeping it? Easy to understand : it's open source, reasonably upgradable, sturdy and can print almost all the common plastics on the market. Some people will argue that the print volume is too low but nothing is impossible with a good design. During weekend, I was trying to print one of the gear bearing spinner proposed by the community, once again, it didn't complete. I knew the root cause : The extruder stepper driver was in security mode due to the poor cooling. It was just overheating (as usual). I did a full stepper drivers replacement, last year. Unfortunately, I had to revert the replacement for the extruder as the TMC 2208 drivers are causing problems (not extruding) if you use the linear advance feature. The problem is disapearing if you use TMC 2209 drivers. If you add to this the fact that this printer is originally equipped with an amenic and noisy 40 mm side fan, you have the perfect combo. It was time to act, I was fed up. First, I opened the printer and checked if it was possible to move the drivers => nope, too messy Second, I checked if it was possible the controller board outside => possible but too messy, too I finally decided to use my angle grinder, make an hole, just on top of the controller board and install a 120mm fan, outside. Wait, outside ?!?! Yes, outside. As I mentioned before, this printer is not the piece of design of the decade and putting the 12v, 120mm fan inside was too tricky due to the bad cable management. This is leading me directly to the "project". I needed 4 feet for my Mecreator2. I found some on Thingiverse but I didn't know the clearance height. Another occasion to practice my favority CAD software, Fusion 360 ;) After a few minutes of hard design (joking, I went to the essential), I was ready to print this almost 4h print(0.3 mm / 15% infil ). The ideal occasion to test the new cooling "design". I set my printer on planks (no feet, waiting for the print and didn't want to use the resin printer), I crossed my fingers and started the print. And guess what? It worked as expected. Now, I'm more confident to start longer prints. Enjoy!
