Stepper Motor Control??

[The Gresley Luthier]

Hi.
Thanks to members of this site I have decided to build my CNC wood router using NEMA 23 stepper motors. Due to space restraints in my workshop I have decided to build a Floating bed, Fixed Gantry frame, so I need x3 Steppers. I already have several Arduino Uno's I can use, but I understand the Arduino CNC shield can only handle up to 2 amps each, the NEMA 23's will probably be 2.8 amp. Does anyone have any advice on this? I have Googled this problem but things seem a little confusing. Do I use the Steppers with there own Driver, can anyone supply me with a wiring schematic I may study??

Regards.

Ray,

I feel you are on the path of building a 'toy' cnc machine.
You need to do more research, start by looking through some of the build logs on this forum, there are plenty of schematics to be found. https://www.mycncuk.com/forums/253-D...ter-Build-Logs

Hi, Thanks for the reply. "TOY" maybe to you, but a serious piece of kit for me. I first used a CNC milling machine in 1968, during my apprenticeship, I have been fascinated by them ever since. Its not mechanicals that bother me, but as my thread states I need electronic help, The threads you have pointed me to look mainly mechanical build, Bit I will Plough through them.

Regards.
