Don't stop when hitting a Limit Sensor
« on: November 13, 2019, 04:37:14 AM »
Hi members~

I made a fresh install of Windows 10 Pro in my Dell 9020M micro computer, and installed MACH4 4338 and ESS 250 plugin.

I finished configuration, and checked the home and limit senors work.
(I did it with "Diagnostics - ESS v250")

When I slowly(very slowly...  STEP by STEP) move an axis to a limit switch, MACH4 stops(E-Stop)., but when I jog the axis in normal speed(F1000?), MACH4 does not STOP on the limit switch and pass to the end of the axis keep making squeaking noise...

Why did happen?

And when I try to reference home, the axis just move to pass the home sensor.
(But in the Diagnostics - ESS v250, home sensor is correctly working.)

Would you please give me some help?

in pokeys you must fill all parameters of behavior of the homing cycle
like if stop when touch or return...etc
i consider you already did that and still have the problem
we mate such problem with pokey when the accl/dcll was too slow and its not stop enogh fast then its heat the mechanic or the limit
pokeys solve now this problem ,that pokeys take the accl/dcll parametrs from mach also about the homing

Oh... You are my SAVIOR!!!
I could hardly expect that my motor configuration was wrong, because I just put the same values as I had in the former computer.
I don't know but the motor configuration was changed (maybe by MACH4... the values were all the same...).

I put correct value and found it worked!

Now the limits work. ;)


Thanks again KatzYaakov~~~
