Re: A poor mans CNC machine
Thanks, Ive been keeping various parts through out the years for this new design (as I ditched the old) and if it has major problems I just might have to order parts to get it finished.

Re: A poor mans CNC machine
I might mention that home centers suck when it comes to component costs. So not the best way to buy build materials, especially anything involving metal.
My laptop died so I will not be able to see much detail but it does look like your machine could use more thought in the bearings. Generally the cheaper the bearing solution the farther they need to be spread out.
Re: A poor mans CNC machine
For sure materials are expensive, even bolts and brackets. Ive used an Ikea bed for the X base, the metal supports are sourced from a bed board, and a ladder for the table.
Each wheel has two bearings so there are many... here is my Z axis and table design.

Re: A poor mans CNC machine
Thanks, although the Y-axis is very stiff to move back and forth, Im getting lots of flexing.
Im not sure if some ad-on bracing will fix this, maybe centering all the wheels to the Y bar might help?

Re: A poor mans CNC machine
i realize that everyone's machines are a product of what they can afford, and material availability. i got a deal on my machine, due to pure luck i think.
i am concerned about the flex you mentioned. (haven't watched the videos yet.) maybe i missed it, but what is your end plan for this machine? what are you routing?

Re: A poor mans CNC machine
I would like to transform the front of an old sports car into a new design by carving pink HomeDepot foam for the mold.
Im thinking of stacking some square tubing I have, inplace of the ladder braces Im using maybe to reduce flex seen in the video.
