Hey, new here, looking for some help regarding machine setup/config.
After getting tired of the size limitation of my little 3018 I decided to build something a little bigger so I started piecing together a 1000x1500 unit, water cooled 2.2kw spindle, gantry frame, nema 23 closed loop steppers.....
Trying to 'get it going' with a 'duino for now but the drivers dont appear to want to accept instruction....
With the drivers powered up the Steppers hold position and when sending a Jog command the enable signal unlocks the steppers however the steppers just squeal. Im guesing there is a problem with the Pulse/Step but I cannot work it out.... I have tried various step durations, as according to the manual for the chinese drivers it needs to be longer than 10millisecond, with no luck...
The steppers operate fine using a CNC shield (abit much for the little drivers, the get warm quickly) so they are not an issue...
The supplier states the steppers will not work without the drivers (obviously they do just not in a closed loop fashion)
and made remark about not using Mach3 for control but i think a language barrier may be an issue getting info there...
Any suggestions/advice much appreciated....
