Help with CNC 3018 from Banggood

[AndyUK]

After hours of reading, I changed all my limit switch wiring to shielded wires……..Nothing still same issues.

Hi Jean,

Agree with Doddy and Kitwin that pull up resistors are indicated and should be fitted - but haven't seen any mention about shielding of the spindle wiring? You mention limit switch wiring shielding, but not spindle?

If its not already, I'd recommend making that shielded too in order to reduce the noise output. Also be sure to ground your shields at one (and only one) end.

Thank you, Andy,

I will shield the spindle and ground all the shields. I, at least, can do this for the time being.

Hi Jean,

I am a complete novice as far CNC machines go and I have got myself a new cnc 3018 pro machine. I just assembled it and have been playing around with the GBRL and calibration stuff and thought I should enable the homing feature which would need endstop switches.

I was looking at the Optical Endstop that you have mentioned in earlier posts and thought it would be a nice clean method as opposed to using the micro-switch option.

Did you get round to solving the issues you were having? Will be grateful if you could upload a pic or two of what your switches look like and how you have attached them to the XY and Z axis.

Thanks,
Mike
