Using a cheap 3 axis CNC controller #1

Open vender0711 opened 7 months ago

vender0711 commented 7 months ago

Hello, I am also a woodworker and like what you are doing here. I was wondering would it be possible to use a cheap CNC 3 axis controller. I think it would bring the cost down and give you one simply controller to use. I do not program so I have no idea if this is even possible. This is the $25 controller I was thinking of using? It uses a MEGA 328P and has built in drivers, CNC controller Thanks for your great work! https://www.aliexpress.com/i/2251832599320727.html?gatewayAdapt=4itemAdapt

Hello, as far as I can tell from the AliExpress listing this board is suitable to drive the motors that control the gates. But you also need the logic part (aka input to tell them what to do).

Meaning you will probably need an additional controller board which will take the input from the sensors that detect when a machine is turned on and tell this board what to do.

In my setup this is the Arduino board (doing the logic), and the MEGA board is there to drive the motors.

If you take a look at this listing you will see that the set with Arduino/Mega plus drivers is probably cheeper that this board alone - hope this helps.

Side note: I was building this from what I had on hand (old 3D printer with controller and power supply) - and documenting it here for myself and other if they want to recreate this.

I will in the near future upload some additional guides with images to follow along, so stay tuned.

That is what I am trying to do, use up some old CNC parts. The board does have inputs for the logic part. Oh damn that is cheap. Thanks

Could a relay be added to turn the dust collection on/off?

vender0711 commented 7 months ago

I am going to build one. I like what your doing! Any idea which model would be best? Thanks for your help https://www.aliexpress.us/item/2251832522572842.html?spm=a2g0o.productlist.main.1.27f94eca3K1ht3&algo_pvid=d00c7cb8-7299-4292-9055-4f5a5855cc13&algo_exp_id=d00c7cb8-7299-4292-9055-4f5a5855cc13-0&pdp_npi=4%40dis%21USD%213.77%213.77%21%21%213.77%213.77%21%402101fb1017098234444333505e1e0d%2166287665257%21sea%21US%211911867813%21&curPageLogUid=Ryar4NlbQ6Xw&utparam-url=scene%3Asearch%7Cquery_from%3A

Sure a relay could be added to trigger the dust collection ... I know they can be controlled via an Arduino (have not done it myself - as all my machines are 3-phase and I have a dedicated switch to do so).

The SCT013 is the correct measuring sensor (the exact one I'm using) ... buy the cheapest one that you can find - these are identical - only different merchants.

A quick google search I found this guy explaining how to do the relay part: https://www.youtube.com/watch?v=d9evR-K6FAY

Happy building.

3 phase, commercial building or just your grid? also i do not see a donate button? I pay what I can for others hard work. I would like to give you something when I get it working??
