Delta printer won't move after G28 command

Well as in the title… after G28 it’s homing then it stops. I can’t move it anymore after that and i’m able to use G28 only so it get back a little and stops on endstops again. Endstops are working fine. Don’t know what’s the problem here. And i’m using config file from the guide(this one for delta printers).

I’m working on a Delta printer too and in some way I had the same problem. I don’t know your exact situation, so I will descripe some possibilities:

  • Do you use the Repetier-host software? Because it need some changes in the printer settings.
  • Do you use “alpha_limit_enable” for example on one or more towers? (default off is just fine).
  • And I like to know if you used the trim function like “alpha_trim”.
    They are off by default. You could try: tower_trim -5 for instance for each tower.

I’m using pronterface.
I don’t have alpha_limit_enable ar anything about alpha_limit in my config. ( Should i add this or is it off by default?) // added them and nothing happened
I was not using alpha_trim. I tried -5 for them but nothing changed.
Printer still is going up to home position after G28 and after G28 i’m not able to sent any other command other than G28.

What do the leds on your board show after G28 ?

5

Those leds are like this OIIO (O - on I - off) but those in the middle are constantly changing from OFF to ON.

What does sending version or @version to the board return ?

I’ve had the same problem. If I send simply “G28” it does the homing of each axis and then stops and nothing can be done after. I had to unplug the motor’s supply and reset the Smoothie.

I’ve been using G28 and specifying both axis X and Y so “G28 X Y” and this has worked for me. Does the homing, retracts to the distance specified in config, and then I can make it move again no problems.

Tried it but it doesn’t work for me. Is tere any way to fix this?

commitment the debounce_count in the config (delete the leading #) set the count to 400. Save the config, and reboot.

This as well changed nothing but only added wierd sound.
// I managed to rewirite a config file for AZSMZ mini board and it’s currently working(at least movements). I will post my config file when i finish it and get it to work as it’s supposed to so other people with AZSMZ mini would be able to work with their board too.
