After building MPCNC and LowRider I decided to step up the game and replace my Ender 3 v2 with MP3DP! Just started build over the weekend. Will be 300x300mm. Waiting for bed / bed support material to arrive before I order more expensive parts [IMG_3649]

My motors rated 2A tho. What is the side of your bed? I am 325x325 and at a full length with a max speed of 1000mm/s occasional skipping occurs at 6000mm/s^3. For smaller beds I would expect top speed will be smaller and accelerations / decelerations will put less stress on steppers

I’m at 300x300 and running Ryan’s steppers. I think they are 2amp but cant remember for sure. I think I will run into over heating on the 2209s before I get to that point. I’m happy where its at now. the 1000 I had before the current bump and testing was better than any other printer I own lol

Mine are BIGTREETECH TMC2209 V1.3 no overheating While faster print speeds don’t make much difference - accelerations and travel speeds are. I am happy with 3500 accelerations and 1000 travel speed

I have klipper set for 3500 max_accel and 500 max_velocity. I didn’t realize until after the test that it was set to 1000 and 1000. So all of the acceleration test first were done at 1000 mm/s. Haven’t tried to print with the new settings yet. Was doing some bed drop test

What is a bed drop test? I don’t like my bed to drop :grin:

Update on the wavy patterns. I just replaced all XY pulleys and idlers with the ones Ryan sent me. I did that without changing the belt and tension. Left is before, right is after. I think it is a bit better but still able to see the pattern. New belt (different brand) will arrive tonight, I will tr…

Sucks it wasn’t a complete fix but at least it was an improvement!

It really might be a second bent shaft…

I doubt because I was printing a cube another day placing it diagonally. This isolates XY motors but wavy patterns persisted on all sides of the cube. I can run this test again tho, when I replace the belt
