Topic: Printerbed moves in wrong directions after flashing repetier firmware

Yesterday I (re)flashed my da vinci with the repetier-firmware and made a fresh install of repetier host. All went fine, except on manual control in RH, the bed travels in opposite directions and makes a high-pitching sound (during travel).

Does anyone have a clue? Did I by accident change some firmware value?

Mine does that to (up is down and down is up) it still prints fine though.  Are you able to print?

It's that way for a reason, it doesn't know the bed is going down. Rather, it thinks the nozzle is going up.
If it bothers you though you can change it.

Printer owners need to understand that gcode is old, it was written for CNC and machining equipment originally. In that world everything relates to the toolhead movement. So all move commands move the tool, not the platform or bed. So by default software for printers are setup so that move commands move the head , not the bed. In some designs like the Da Vinci the head however is only moved on X and Y so the bed moves instead. So moving the bed down actually moves the head up. This is normal. However some find it easier to switch settings so the bed moves when a command is issued in the expected direction which technically is not normal or correct but if it helps an operator better manage his machine I guess it is up to them.

Yes, printing is fine. But does your machine have that "high-pitched"sound, when you operate it  manual (up/down)?
I use repetier for quite some time and it never made that sound. It occured after the last reflash.

Your z speed is too high in the firmware. It should be around 300.

Wardjr and Carl_m1968, thanks a lot for or the clear  explanation/solution.  The strange thing is, I never had to do this before (flashed it several times).
What bothers me more is the change in sound it makes while operating it manual. It used to make a smooth "zooming" sound , like the sound  it (still) makes when it automatically returns to the "Home-position".  Like I said, it's a sharp high-pitched sound, like is has to overcome some kind of  resistance. No mechanical changes are made to the printer. Btw while printing everything works fine.

Any suggestions?

I would guess this is caused by higher speeds used during manual moves.  If it bothers you it can be changed.

Re: Printerbed moves in wrong directions after flashing repetier firmware

Thanks for the suggestion, but my z speed is set to 100 in repetier host. Should it be  changed in the firmware (eeprom)? Where to check?

EEPROM values override all other settings. Also the setting in your EEPROM is different from the setting in your slicer. The slicer setting is for build moves while the EEPROM setting is for manual moves with the buttons.
