Calibrated but prints still bumpy So I have completed all calibration, but when I run a full new print I get "waves". I have attached what I mean. I have a basic set up prusa i3 with only a mk7 And plan to upgrade, but I have seen mk7 prints much better than what I am getting. 20150503_195317_zpsk1yhcuh2.jpg mod_embed_images_loadimage('e3884fc35d956f47ab21ed1c93d65623', '/forum/thumbcache/4a5/dee/dc7/770/df7/7fb/d7b/cc2/786/225/e6_800x400.png', 'http://i105.photobucket.com/albums/m233/sandbarsurfer/Mobile%20Uploads/20150503_195317_zpsk1yhcuh2.jpg', 'https://reprap.org/forum/addon.php?262,module=embed_images,check_scaling=1,url=http%3A%2F%2Fi105.photobucket.com%2Falbums%2Fm233%2Fsandbarsurfer%2FMobile%2520Uploads%2F20150503_195317_zpsk1yhcuh2.jpg', '', 504761, 800, 400, 'Loading image ...', false); https://reprap.org/forum/read.php?262,504761,504761#msg-504761 Tue, 17 Mar 2026 09:01:45 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?262,504761,507506#msg-507506 Re: Calibrated but prints still bumpy https://reprap.org/forum/read.php?262,504761,507506#msg-507506 tmorris9 Printing Sun, 10 May 2015 20:12:51 -0400 https://reprap.org/forum/read.php?262,504761,507334#msg-507334 Re: Calibrated but prints still bumpy https://reprap.org/forum/read.php?262,504761,507334#msg-507334 drHEEB Printing Sun, 10 May 2015 11:22:37 -0400 https://reprap.org/forum/read.php?262,504761,505616#msg-505616 Re: Calibrated but prints still bumpy https://reprap.org/forum/read.php?262,504761,505616#msg-505616
Change this one to 15 instead of 20

#define DEFAULT_XYJERK 20.0 // (mm/sec)

Change X and Y to 3000 and then move up until you find a sweet spot and E will depend on type if direct drive go up from 1800 and if geared from 700. Z can go up to 125 but no more.

#define DEFAULT_MAX_ACCELERATION {9000,9000,100,300} // X, Y, Z, E maximum start speed for accelerated moves. E default values are good for skeinforge 40+, for older versions raise them a lot.

Raise this one as well to 1800 and go up from there if direct and 700 if geared

#define DEFAULT_RETRACT_ACCELERATION 300 // X, Y, Z and E max acceleration in mm/s^2 for r retracts]]> ggherbaz Printing Tue, 05 May 2015 21:11:30 -0400 https://reprap.org/forum/read.php?262,504761,505594#msg-505594 Re: Calibrated but prints still bumpy https://reprap.org/forum/read.php?262,504761,505594#msg-505594 drHEEB Printing Tue, 05 May 2015 18:47:23 -0400 https://reprap.org/forum/read.php?262,504761,505087#msg-505087 Re: Calibrated but prints still bumpy https://reprap.org/forum/read.php?262,504761,505087#msg-505087
Calibration cubes are basically streigh lines.... That pokemon have several slow downs and accelerations in small spaces.]]> ggherbaz Printing Mon, 04 May 2015 19:58:12 -0400 https://reprap.org/forum/read.php?262,504761,505083#msg-505083 Re: Calibrated but prints still bumpy https://reprap.org/forum/read.php?262,504761,505083#msg-505083 drHEEB Printing Mon, 04 May 2015 19:33:01 -0400 https://reprap.org/forum/read.php?262,504761,504891#msg-504891 Re: Calibrated but prints still bumpy https://reprap.org/forum/read.php?262,504761,504891#msg-504891 ggherbaz Printing Mon, 04 May 2015 10:39:53 -0400 https://reprap.org/forum/read.php?262,504761,504762#msg-504762 Re: Calibrated but prints still bumpy https://reprap.org/forum/read.php?262,504761,504762#msg-504762 drHEEB Printing Sun, 03 May 2015 21:30:02 -0400 https://reprap.org/forum/read.php?262,504761,504761#msg-504761 Calibrated but prints still bumpy https://reprap.org/forum/read.php?262,504761,504761#msg-504761
