i am a bit confused as to how the microstepper works here, you have it set a 1/16 so does that essentially mean that it requires 16 impulses from mach3 before it will send 1 impulse to the stepper motor. If that is the case that seems like an artificial form of accuracy.
@koncertLive Yas and no... Mach does send and extra 15 steps (the regular step + 15 more = 16 steps), but the driver does the job of establishing the micro steps. In other words, it is the driver's responsibility to make sure that Mach's 16 steps will translate to a 16th of one step.
@anajonesr so how does this benefit the machine in anyway, other than require a computer that can handle such a huge kernel volume. In your exmple you talk about using a 2 turn per inch lead screw with a 200 step motor. That leaves ou with only 400 x 400 points of contact with your cutting head. That sounds like n atrocious resolution?
@koncertLive I recommend 4 microsteps for lead screws with 2 turns per inch. This translates to 200 x 4 = 800 steps per revolution for the motor, and with 2 turns per inch, the actual steps are 800 x 2 = 1600 steps per inch. This is a good resolution and the kernel will be able to handle this with relative ease. I'm not sure I understand the 400 x 400 points of contact. Can you elaborate on this?
@anajonesr If you have a lead screw of 2 turns and a stepper of 200 turns that is only 400 actual positions per inch your cutting tool can make. I like your videos very much and find them very informational but I am failing to understand what benefit you receive from forcing the software to generate these extra steps just for the micro-controller to consolidate them.
@anajonesr FYI, I have the EXACT same set-up you have described here. With the exception that I will have a 4th motor and driver slaved so I can run an dual overhead gantry system. I have purchased all of the electronics for my cnc but have yet ordered the framework. I intend on using supported 20mm linear rails with my truck gapped at 6 inches to eliminate play but the one thing I have not set in concrete is the drive system. I could care less about speed and I am focused purely on accuracy.
