I want to build a rotary for my stock k40. What is the step angle of the stock Y axis stepper? What is the max amp motor that can be wired directly to the stock board? Thank you in advance.
motor vary from K40 built models, about max 0.5 Amp.
I found that I could max source 1A to both steppers continuous. So 0.5A should work (Nema17) for a rotary device.
What about step angle or steps per revolution ?
@giavonni_palombo most stepper have just 200 steps per revolution. You use the electronics to make micro steps like 1/16 or even 1/128 with the latest step sticks. This effectively multiplies the resolution of the position. Pretty standard.
1 amp is about what the PSU could deliver, take care when you choose your stepper max 0.5A. and don’t forgot to unplug one of the 2 stepper (replace).
@giavonni_palombo I measured 200 steps per revolution when playing with an arduino controller.
Im thinking something like this but only 1 stepper a small nema 17 or a nema 14. The person explains that if the rollers are the same size as the dive gear on the k40s Y then there is no need to adjust mico stepping. Make sense. This is what I want, not to have to adjust mico stepping every time I want to use the rotary. So I should be able to get a stepper and unplug the Y then plug in the rotory and do nothing else. Correct? Im just trying to see if the Chinese didn’t use some unique stepper that will take more that a simple unplug the Y and plug in the rotory.
Stupid question…Will that fit under the laser of a stock k40?
