Hi, found this old post. Hope that it is okay to post here. I am looking to install proximity NPN switches too with my PoKeys57cnc board. I am not an electrical engineer. I understand from this thread, that I have to wire a pull down resistor between the sensor and the keys57 board, but in this manual https://www.poscope.com/wp-content/uploads/downloads/Pokeys/LibrariesAndPlugins/Mach4%20and%20PoKeys57CNC%20-%20step%20by%20step%20guide.pdf page 15 it just sounds like you can connect the switch directly, but they mention an built in pull up resistor. So i am kind of confused here. I would of course like to do the right thing, so that I don't blow up my keys57 board.

Ahh it may be the velocity I has to play more around with. Will be looking more into that later today.

Mach4 General Discussion / Motor chops
« on: May 24, 2017, 03:07:19 AM »
Hi,

First of all I am new to all this, so sorry If anything is obvious for you guys.

My setup:
Pokeys57cnc controller
4x postep25 driver
4x nema motors
Windows 10
Mach4

My problem is that when I manual jog the motors, all seems to run smoothly, but when I press return to zero, some of them chops, and doesn't run as smoothly as if I manual run the motors.

 Has anybody of you an idea of what I can do in the settings to fix this?

Thanks

Do you mean reverse like the option you can tick in the motor configuration?  (Mach-configuration -> Motor -> Little reverse tick on/off box)
