General Mach Discussion / Re: DRO works, motor does not

RICH<      Thanks for the advice, I've checked the new motor, wired it to the Z axis, which I knew worked properly, to test it; it turned. Then wired it to the A axis and it turns, also. Problem solved, now onward to 3d printing.   Pico

I have found a reference for writing the terminal of my Hobbycnc 4th axis to my stepper motor. It is: A blue/white, a red, common blue and red/white, common black/white and green, b green/white, B black. Any comments?   Thanks,      Pico

I'm back with several other problems, as usual. I have replaced the motor with a Lin Engineering 5718M-02E-03. It's wires are: A blue/white, C red/white, A(with a line over it) blue, C(with a line over it)red, B green/white, D black/white, B(with a line over it) green, D(with a line over it) black. I'm assuming that the letters with the lines over them are the small letters; is that correct? The Cs are obviously the common and am I correct in assuming the Ds are also common? But here is the big problem: I wired this A axis into the controller, jogged the other 3 axis, which worked fine , tried the A axis, the dro functioned but the motor didn't turn. But then I tried the other 3 axis again and they didn't work, either, yet the dros function. Not certain where to go from here. In a thread called " mystery motor loss", Hood suggests that working dros and non working motors may be the result of a parallel port out. How do I diagnose that? Thanks,   Pico

I have an A motor problem. I wired the Z motor to the A terminal and got some humming, turned up the Vref and got movement. Thanks for the advice.     Pico

Could it be that the driver and motor are not compatible? The motor spec sheet recommends drivers BSD-01P, BSD-13G, BSD-02,and BSD-02LH. My driver is SK Japan SLA 7078MR 1303 P. Thanks,  Pico

I've seen the spec sheet. I have connected the A motor leads to the Z axis terminal. Orange to A white to common,blue to a, red to B, black to common, yellow to b. Although Z works fine, it can't move the A motor. I have checked the amperage between leads, it is 5.7 between orange and blue ends, with 3.7 between blue end and white common, and 4.7 between orange end and white common. On the B side, it was 4.7 between yellow and red ends and 1.3 between yellow end and black common and 3.7 between red end and black common. The amperage on that motor is adjusted a bit below 1. Thanks,   Pico

I am attempting to make certain my motor to terminal connections are correct. I have tried many combinations and not gotten it right yet. One problem is that data on the stepper motor, a Sanyo Denki 103H5208-10U41 is lacking. What is the A,A com, a and B, B com, and b ? Here is an image of the colors of the leads from the motor. Thanks,   Pico

DROs work and now it jogs, after turning off and on. I am going to look to see it I made any solder bridges when building the kit, also looking at motor to terminal connections. Thanks,    Pico

Good idea. I swapped the Z and A axis values out and was able to jog the Z axis with the A axis but not the other way. So must be something, possibly how I wired the 4th axis conversion. I look at that tomorrow. However, I changed the values back and now I can't jog at all, the resume and jog off/ on is green. Any ideas? Sometimes this thing drives me nutz. Thanks,   Pico

Thanks for the advice! I reduced the Vref to half of the other motors, which were twice as large and the temperature is about the same as them. I found a mistake in the ports and pins menu, I swapped the step pins and ports values. Now they are correct: A step =pin 9, A Dir= pin 8 and step and dir port both = 1. Still no movement in the motor. Back tto fiddling around with the wiring to the terminal.    Pico
