hi so i got a ox cnc that i have tried for a while now to get working. but i have spend soon close to 100 hours to get my protoneer and rpi. but i think i found the one that got away. i am an electrician and have a automation engineer degree so im a bit surprised i cant get it working. now im tired of all the troubleshooting and looking for a new motion controller. i have this kit but with 4 motors and drivers. Special Offers : Big Sale 3 Axis 3.0Nm(425oz.in) Nema 23 ... would the black box be able to handel my motors? how do you connect it to the computer? computer requirements to run the software ? how do the setup looks like (not wiring)
Motors of that size have no place on an Ox. Get 4 of either Nema 23 - 57 x 57mm : P Series Nema 23 Bipolar 1.8deg 1.26Nm ... or Nema 23 - 57 x 57mm : P Series Nema 23 Bipolar 1.8deg 1.9 ... and a BlackBox and you're good to go.
Chinese OX? I did the same and paid for it ditch the controller you have been messing with and go to the black box worked for me amazing device and will handle those motors fine. Very easy to set up.
that would not happened, the motors are already fitted to it, but pleas do explain why you feel that way. how do you connect it to the computer? is it hard to set it up?
Oh sure they'll fit but you're just hauling around a lot of unnecessary dead weight. The teeth will skip on the belts long before you get to using their full potential and the weight of the Z-axis motor way up on the mast will cause the X-axis to flex each time there is a sudden change in the Y direction. Remember the original Ox was built with a piddly little Nema 17 (which only turned out to be insufficient because of the unnecessarily aggressive slope of the Tr8*8 lead screw). The Z-axis need not have a stepper greater than 1.26Nm and the other axes 1.9Nm. But if you're going with the motors, drivers, and power supply you already have, all you really need is an Arduino to make it run. There are plenty of examples on the forum and online as to how to hook it up. You can also use the free OpenBuilds software to run it (as well as many other Gcode based freeware and payware programs that are out there online).
aa ok that make sens, so 400 g makes that differens? well my plan is to run this set up for a while and then upgrade it more and more to get rid of the belts. but if i change the z axis motor then i will not have any problem other then i cant go full power? ill probably are going to test it with arduino.
Is it the same like cnc router model BobsCNC E3 CNC Router Engraver Kit ? I'm doing a simple comparison with some models of CNC routers ( from here: https://www.wоodroutersreviews.com/best-cnc-router/ ). Genmitsu is also great, cause it comes ready to use from the box.
