1 - This was amazing to watch, the progress combined with all the cool features you added are awesome 2 - The sounds from the nozzle camera and also seeing the tall PLA-CF object with the Z decoupling system were both so satisfying :) 3 - Would you consider making another video telling us about everything you learned along the way? I learned a lot from this video already, but I'm sure you've picked up a lot of valuable knowledge and experience from these builds that I'd love to just hear you talk about in more depth, maybe like a "director's commentary" on this video :P
@davidwang_3dРік тому
Thank you. About making a video of what I've learned, it is unfortunately unlikely. I really learned a lot, but it's complicated to keep track of what I've learned. But I can tell you that most things I learned are surrounding a central core, that is Klipper.
@nathanjakerРік тому
That makes sense. A commentary over this video might help with keeping track of things, but understandable if it's still too much in your opinion. If you found Klipper most interesting, maybe you could do a video on your favorite/most useful Klipper functions/implementations? I'm just so curious to learn more about everything you've accomplished after seeing this video!

@Mr.Thermistor72287 місяців тому
glue stick the entire area of where the print is going to lie on the bed! there is nothing to lose and it always works. glue stick has recently been one of the things that has totally up my printing game. i was a denier for awhile, but then i used some purple elmers stick and since then i havent had a SINGLE corner of any object lift off the bed a warp, not a single one. i have used glue stick on every single print i dont start a print without it no matter the size and shape of it, its a game changer if you were like me still and a denier, highly recommend
@davidwang_3d7 місяців тому
It really depends on material. Gluestick is beneficial for PLA, which usually doesn't stick well enough, and PC, which usually sticks too well. But for PETG, gluestick actually ruins the adhesion and makes parts more likely to come off during the print.

I really don't know what to do with my ratrig. I got to a point it's "consistently reliable". Not mega fast but it's quick enough. I want to upgrade it rather than putting out another £1000 + for a 2nd printer. I don't know if I should do AWD or IDEX.
@davidwang_3d6 місяців тому
IDEX will not make it fast. IDEX gives you the option to print two filaments with quick tool changes. AWD will make your printer faster. If you want to save costs, start at using 48V and TMC5160 for your XY steppers, and it you are not happy with the performance, then you want to go AWD.

Awesome video, may I ask what approach you went with to tighten those belt ? I feel like the belt tightening is what is holding my vCore 500, I got everything in metal (fame, vzhead + extruder). I know for sure that something is vibrating because in 2 years, only one time did I tighten the belt perfectly.All print, material and speed had perfect quality. I never got that print quality again because at the time I was clueless of what was going on. Thank you for your videos.

I move the gantry to one side, adjust the belt tension of each belt until the gantry is completely parallel to the frame.
@mophie6941Рік тому
@@davidwang_3d After reading this I went and corrected my gantry. I am sure I had it parallel but It somehow had 8mm of play now. I made sure to undo all twist in the linear rail Y+X, I could feel it had resistance. Oh boy did that make the difference. Before with input_shaper enabled I had a bad ringing that kept appearing no matter the accel/speed. Now I can make it disappear with lower accel on parameter. Doing all test in silk pla might not help with my perfectionist eye tho....😅

Overall are you happy with this large size? I have been wanting to build one for a good while but am scared of running into issues due to its size. Like the gantry and bed warping, bending, and or sagging. Do you use the large build plate enough to where its worth it? If you could go back, would you still pick the 500mm size? Thanks for your time and help!
@davidwang_3dРік тому
I didn't really have an option but to pick the 500mm size. The reality is that most things I print fit in a 300mm, but there is always sometimes I had to print something really long that only fits on the 500 diagonally. Yes, the bed mesh isn't great, it's at about 0.4mm variance, but that's not the bed itself, but the gantry sagging/bowing, which can be dealt with. Personally, I think it's better to have a large machine but print mostly small things on it, than having a small machine and worrying when there is one time when I need to print something large.

if you were building from scratch and were planning on doing AWD with the carbon gantry from the beginning, would you think that 600mm3 would be sensible?
@davidwang_3dРік тому
Firstly, 600mm³ does not equal to 600mmx600mmx600mm, but I get what you mean. There are reasons why I chose the 500. 1. 500mm is a standard kit and it's easy to order from Rat Rig. 600mm is not a standard size they sell, and I have to self source everything, which would cost me a ton more. 2. The larger the machine, the less stability, the frame has more leverage to wobble. 3. The gantry gets heavier, and the belts get longer, which means more ringing, and less acceleration. 4. The bed also gets significantly larger and heavier, which increases variance on bed mesh, and it takes significantly more energy for it to heat up
