Steel framed fixed gantry draw slide build super cheap

Just a few more photos of the z axis, i will fit the lead screw tomorrow if all goes well.

finished off the z axis today, i finally gave up on having supported bearings on the lead screw and mounted it directly to the motor as ill only be using this machine for wood/plastics it wont be a problem

So today I made some progress...
I mounted x axis to the base
I updated z axis face plate to alloy insted of ply
I decided I didn't want the y axis motor sticking out the side so
I mounted it inboard

Sorry to sound negative, but you will kill that Z stepper very fast if you start using the machine. The screw seems to be hanging on the motor axis, which is a VERY bad idea, since the motor and the motor bearings are not designed for that heavy job. Same on all the other axes as well, but the Z is probably the most critical, and at least one end of the screw must be fixed. I also don't understand why use drawer slides. Those have just too much play and are not fit for the purpose. But OK, if learning is the purpose then fine, but considering the time you must spend on this, I am sure that real parts are better investment than parts which later on must be replaced, especially considering that replacing and squaring will be very difficult since you have welded everything possible to weld.

Don't be sorry the world is full of negative people !!! the stepper bearings will cope no problem,I am using heavy duty draw slides as i wanted to build a machine that uses alternative components as much as i can

Can you do me a favor and start a thread on your machine that way you can remove your links from my post and place them on your own post

He hasn't placed any links on your post. They are part of his Signature and are on every post he makes which is perfectly fine.
He's also correct in what he says and I don't see it as being negative.? What your doing is joke in terms of real cnc machine and these Important things should be pointed out for the sake of others who are new and thinking this is acceptable way to do things. It isn't correct or accurate and it will cause problems or fail so he's perfectly correct to point it out.
End of the day this is forum for debate and if you post something then don't get upset when someone disagree's with how your doing things. Either explain why done this way or choose to just ignore the poster or better still accept and learn from them. But don't tell them to go away just because they are not blowing smoke up your arse or not saying what you want to hear.!! . .

Why do you think its not acceptable to be creative, innovative, and experimentative and do things differently ? after all there's more than one way to make a chocolate cake right !!!
