the purpose of the M8 washers are to eliminate any movement from the lead screw which passes through as the bearing and shaft collar alone is simply not strong enough to stop any movement, plus the...

here is the link to my post about sorting the movement out in your z axis spindle motor housing..
...

no need to apologise we all have to start somewhere, i too have the 3018 and may or may not have a different control board to yours so what i would first suggest is put a couple of decent pictures on...

hi dennis on your control board you have the following input terminals IN1 IN2 IN3 IN4
you can use any one of these to attach your touch plate wire which ever one is not being used, then...

edit: dennis i have just checked and the touch plate wire has to go to one of the input terminals (not the 5v as indicated)

thanks steve i am going to mount my variable speed 240v 35000 rpm dremel look alike rotary tool as i did a mock test with it and wow what a difference it made, cuts were so clean and increasing the...

hi dennis are you able to upload a picture of your control board? if you can then we can see what type you have and possibly its pinout for you so we can help you further.

i bought one of these machines and after a couple of weeks my spindle mount (Z axis) had over 3mm of play in it. here's how i solved it.

First take the motor out, followed by the whole z axis...

this is the same steve yes only difference is mine is the bigger frame/table model (3018) which basically means 300mm x 180mm working area.

thanks for the suggestions I'm not too bothered if the motor is running at full speed, and was wondering if you could tell me if this could be used on the link below
...

not identical but practically the same yes, so i don't mind going down the route of utilising a separate power supply just for the new motor but i have not got a clue what parts to buy or where to...

control board is here Al in this other post about the controller which i have since figured out

tested on my car 12v battery and works ok so its looking like i need to find a separate power supply for this as per Sterob's reply as well.

power supply i have is 3amp 24v dc output which came with the machine along with another power supply that is 12v dc output, both power supplies plug into the controller and the Arduino is powered by...

thank you very much al i will check it out and report back

i bought a 775 18v dc motor for my cheap cnc 3018 from here

I will see what information I can find for you roger and I appreciate your help on this.

thanks roger for your reply, but I have no idea what you mean by pulse engine or interface. all I know is the control board has an Arduino nano on a shield board with the word developower v2.0...

hi to all, i have made my own touch plate with small croc clip on the spindle as negative and the plate running off pin A5 on my arduino and i am using grbl control software. when i run the z-probe...
