x still crashes against stop and not homing correctly

[szeiger]

I have uploaded the new firmware you provided and have finally been able to print some useful parts. Thank you. But, the printer still crashes against the X stop. I have changed the settings in configuration.h to true as you instructed but it did not help.

Additionally, when starting a print, it does not position itself correctly, making the nozzle crash against the metal clips that hold the glass to the hotbed.

Please help.

Hi, szeiger
According to the time you submitted your posts, it seems that you have solved your problems. But I still want to ask, have you solved your problems? If not , I would be glad to help you.

yes, moast of my problems have been resolved except the start position of the print. Where should the print head be in relation to the bed, and why doesn't it put itself in the right position?

When the print head is homing, It's position is as shown in the picture:
