I just finished my OX CNC build, but having issues with motor current. I am using the CNC xPro controller from openbuilds Nema 23 motor from openbuilds. bosch colt router My build is 1000mm by 1000mm using the OX plates, gives me a 818mm by 700mm cutting area. My issue is that i am not getting any cutting force to speak of. I have created a job in Sketchup to plane my spoiler board to level the board to my spindle. If i set my feed rate to around 800 then i can cut a depth around 1-2mm, but it i try to cut 3mm deep then my motors will skip and stop turning. I have tuned the current following the xPro instructions. I am at a point if i turn the current POT another 8th turn then the motors wont run(assuming to much current), but i still get bad motor steps. What i think is going on is the controller is not powerful enough to run the nema 23 motors, or that the motors dont have enough torque. Motors are rating at 2.8 Amps and the controller is rated at 2.5 amp peak, but run around 1.75. Has anyone built a maching this big using the xPro controller? If so can you share how you got good cutting force. I am thinking of buying new motors, i am looking at these. http://www.automationtechnologiesin...14”-dual-shaft-stepper-motor-kl23h2100-35-4bm But if i get these then i need to upgrade the controller, which i am looking at. Gradus M1 PRO GRBL CNC Controller With the bigfoot drivers(if they are avaiable yet). It will give me a 4 Amp driver and should run the 3.5 Amp motors. I am alos looking at a new spindle. If anyone has a spindle in mind pls let me know. My over all goal for my CNC is aluminum milling. I just want to pass this by a forum before i replace my motors and controller. So any feed back is greaty welcomed.
