Hi !
I http://geeetech.com/firmware/ I see two types of files to download
A30_APP_S_V1.38.61.bin и A30_APP_M_V1.38.61.bin
this is the slave and master
What's the Difference ?
Which one do I need to load into my A30?

Thanks !

Hi !

I have the A30 c EndStop located at the top, but it's not very convenient ((
I want to remake to the bottom
How can I do this - please give instructions

Thank you, Vadim
