Hi all,
this is my first experience on CNC stuff. I've bought a 5 axis board form ebay (link) and motors (57BYGH56-401A, link). I know that is cheap material, but is what I can afford by now. I've seen many threads about this (or similar board), but can't find a good answer (I'm italian, not so good on english).
I'm using the board with a 24V - 15A Power supply (from e-bay ), and I'm testing/tuning the motors without attaching them to my DIY MDF machine. Motor turns, but not so good. They are very noisy and when moving slowly, they are absolutley not smooth (toc-toc-toc-toc...) Trying different settings, but missing the point, so let's start from the beggining.
Current Setting
I can set 100%, 75%, 50%, 25% of current. Specs say they are 2.8A motors, must I set it to 100%? Now I'm trying with 75% (don't want to burn it, noob on electronics).
Decay mode
Don't know what we are talking about. Playing a bit with dip switches, FAST MODE seems to be the best.
Microstepping
Full step is a mess, half step works but some steps are lost along the way, 1/8 seems to be smooth. How does it affect the torque and speed?
Someone has used these components with success? I'm looking for a config that make it works as better as possible. After the dip-switch setting, I will play with the "Motor Tuning" dialog in Mach3.
Thank you
