Jackpot3 x motors moving at different speeds

Software / Firmware General
1

My axis motors are moving at different speeds. How do I get them to be the same speed.

This causes the axis to skew when moving. They worked fine using the Ramps board and Marlin firmware. With the Jackpot3 and FluidNC firmware they move at different speeds.

Any ideas?

Unless the configuration file has been modified (only you can answer this question), the most common causes of this is are

  • loose grub screw on one of the stepper pulleys
  • stepper pulleys are mismatched (one 16T, one 20T)
  • belt misalignment so that the belt is running on the stepper pulley flange instead of against the stepper pulley teeth.

Power up the board, them copy/paste the output of the $SS command from the terminal.

Use the preformatted text option in your post to make it usable. It’s on the editing toolbar and looks like this: </>
