Hello, so far I made all the physical buttons work well but I found a problem with resuming prints the second time. The first time I press stop and then start (in web UI or physical button) the resume position is correct and the printer continues to print properly from where it stopped before but the second time I stop and resume the print, the Z axis gets lost and even causes the motor to hit the limit.

This is a strange problem that looks like RAMPS loses the correct position and just resume the print in wrong position. I use the /printer/stop and /printer/resume commands to run the physical buttons.

My setup:

Hi all,

I am using Build 1326.

I was trying to generate a mask and I found the following problem I do not know why.

When I press Preview (Display Mask) the mask moves laterally and longitudinally.

The two next images show the problem.

Thank you so much,

Hi,

Can I create a physical buttons to execute orders directly using GPIOs from Raspberry.

For example: I want a physical button to Pause the printing proces, one for Resume the printing, for Stop the priting proces and also a button to go to the home position.

Thank you so much

Hi,

I have a question about the LCD 16x2 i2C.

When I start the printer the LCD has the backlight on, but when the printer starts to work and has connection the LCD backlight turns off automatically.

I want the backlight on all the time. Do you know how to di it?

Thank you so much,
