IDEX Toolchange Speed

RogerPodacter

I am trying to have consistent toolchange speeds on my IDEX printer. only the right U carriage changes speed fast, the left X carriage is very slow during the travel moves. Print moves are fast. only the toolchange speeds are slow, yet i have all settings identical between left and right carriage.

what am i missing?

@RogerPodacter in the G1 R2 commands in the tpost#.g files, try adding a feedrate parameter, for example F10000.

What firmware version are you using?

RogerPodacter

@dc42 i am on firmware v3.4.2. i removed that command and all is well now. i did not intend to use that specific command.
