Building My First CNC Router, Looking for Advice & Other Info

[AlexDoran]

I'm sorry to inform you that the fourth axis on the controller is only rotational and can't be slaved. Have been drooling over it myself but have to go another way as I'm using 2 motors for my X axis. Boyan runs it with two drivers on the same signal but because of that he lost the ability to home separately.

I see, i also had this answer in another thread, a couple of the guys thought that it should be fine as long as there are no major crashes and i have a method for adjusting the gantry to be tram.

Hi I had KJN cut and drill my frame (With counterboring) which is a little cheaper than using the corners but also stronger. They will do it to your cad model, you could still use corners as well for extra strength.

Cost me £35 +vat for 18 holes with counterboring.

I already had the corners I did it for strength, I used m12 50mm A2 socket bolts.





A top tip if you do what I did make sure you get some corners then use them to get the extrusion straight before putting the bolt in when it's tight you can remove the corner and reuse.

Also 9045 extrusion takes M12!!!

That's a good shout, i will be buying my Extrusion from KJN too, i have used them in the past! Are brackets alone not rigid enough do you think?

Thanks
