E-stop easy go into inputs and toggle active low if it's cross change to tick or vise versa.

I wouldn't mess with drives it's very easy to let out the magic smoke just connect motors and chances are they will work and absolutley don't disconnect motors from drives with power on when you get them it WILL BLOW THE DRIVES.

i hear ya.. read that on different sites...

thinking of 3.1nm motors.. would they do the trick ,

For the vast majority of machines 3.1Nm motors are a good choice. If the machine is small enough to use smaller motors its hardly worth it as the cost saving is so small. Unless it's a big machine (towards 8x4 size) 3.1Nm nema24's are good. What size is the machine?

not sur jonathon, think ive mentioned in earlier posts maybe 4 x4 to begin with... a starter... then progress... 4x6..what would be the limit ... could go 4.0nm but is that overkill.. mainly timber and mdf stock...


Can i just say this forum is awsome,,, so helpfull for us noobys so too speak not feeling like we are being talked down at by the people that know more than us... that has always been a pet hate of mine on some forums, infact when ive read some posts ive not even registered.. so thankyou all... especially jazz and jonathan..
