Prusa I3(or other machine)

Hello, have a fine Prusa I3, found some miner minus whit it, but overall a very good machine.

But trying to print the Bust Lady from tinguniverse around 60% up the print it'ts startet to wooble a little and hence since i using 0,2mm the extruder
hit the print, the statuette has a rounded seat and therefor not stabel,, THE print wasent lose, the tape worken fine, but the fast chance in direction in Y axsis
did the wooble of the print,,, insted off building a BIG raft or support,,,, isent there a G code there can force a soft chance in direction and the print at normal speed
or slow it down just before shift in Y or X ?

You can reduce your acceleration settings if you're using Marlin or Repetier, but that won't necessarily prevent your wobble.

You'd be better off solving the warping problem, which is what I assume you're getting from the description of your problems. If you're printing in ABS, you'll need a heated bed at the very least. Regardless of type of filament, make sure your bed is level and your initial Z-height set correctly. Bed adhesion and heating aside, this is one of the biggest causes of warping. Print the 20mm test cube from the wiki calibration page - [reprap.org]

Thx,, i am a techworker at work,, my axels is near perfect, whitin 0.03mm, bed level the same.
The buste print have a bevel stand, and the weight and fast shift did make the buste woble hust enughf too catch the nozle.

I guess, i should have made some kind off support beside the raft..

My cube print was 20,31 allmost on every side.

Whit Raft i have no problem whit print normal, only this heavy high one, as i wrote, it still was fast to the underlayer
then i stop it, the shift was simpel to fast a directionel force.

I am using Merlin prusa I3, but havend yet connect to PC(dont know how) i still print via SD card...
What was the code to slow down shifting?

You can slow acceleration by sending M201 to the printer (you'll need to connect your printer to your PC and use control software such as Pronterface to do this). Reference here: [reprap.org].

Obviously you'll need a USB cable to connect your printer to your PC, then some control software like Pronterface ([github.com]) or Repetier Host ([www.repetier.com]) to control it.

You could use CURA and there is a plugin Tweak At Z, so you can lower speed after some layers when your print is getting high.
