... I measured about 17 Megohm for all 4 motor lines. I guess your Big EasyDriver is dead Sad

As you did not show the "interesting" information like "ramping", I cannot really help but ask for the full settings of your miniE. Can you set everything so that you are having the problem and then post or mail the settings-file from the SD card?

As my cutout for the display is not exactly, you can’t see the scrollbar.
How can I open the minie.cnf file?
And i wanted to attach the file but the forum says: The type of file that you attached is not allowed. Please remove the attachment or choose a different type.

Can i email you the file?

I made a video from my test shot, and as you can see after the 5th second the system moves fast then in the beginning.

Hello again - you should now be able to upload the configuration file.

The file cannot really be opened as I save all the data in binary form to minimize the file-size and thus also minimize the time needed to save the configuration (which happens every time you are done with entering a value).

Yes here is the file.

Hi Airic,
MAYBE i found some small bug:
The Limit switch input is a bit unstable, in my case a can trigger the LS even with attaching a open ended wire.
I cant measure a voltage drop on the line, it stays around 3,25 V but if the motor starts the LS is triggered. Seems like the Crosstalk in my 8x0,25mm² cable, some small spike, is enough to trigger the LS ? It's not an actual problem, but i'm trying to solve it an keep u informed, just wanted you know about this behaviour.

Greetings
Martin

I added that to the to do list. I guess what I need to do is adding a little debouncing delay and then re-read the limit-switch-line to verify that it really is triggered.

Thanks for the tip!

I just uploaded a new version which should fix the bugs you found.
Cheers.

Thanks Airic,

my yesterdays first test with the new software gives me these results:
The motor now moves with the correct distance not as in my video. --> Perfect
The "Jog motor" function, works at the first use not correct, but i tried to reproduce the error and it didn't happen again --> Test later once more
The "Pop Up" "Go home all" function is not fixed. the motor still rans into the wrong direction Sad

Cheers Sascha

*Argh! I am definitely setting the direction pin but sometimes the pin state changes according to what I am settings and sometimes not. Could that be a bug of the SAM3X processor of the DUE? I will continue investigating that.
One (possibly dumb) question: did you also update the libraries in your Arduino folder?

Cheers.

No I didn't should I? I will try this in the next days.
