I'm working on trying to size my CNC build and had a question with regard to the weight of the gantry.
My plan is to use CNCRouterParts bearing blocks with 1/4" steel and rack and pinion gearing. I planning on a rough size of 48" x 48" surface area for cutting.
So, for my Gantry/"Y" I was planning on using some lumber I had left from a job we did some work on, 1 3/4" x 6" Oak, laid flat spaced apart with an 8" piece of steel to bolted to the front then to connect that with the the x axis using an aluminum plate on each side to the x axis bearings.
I'm planning on using the following for the steppers and controller, thoughts..
G540
KL23H2100-35-4B 381 oz motors
KL-350-48 48V/7.3A power supply
Obviously cost is a factor, so my concern is about the weight of the gantry and your thoughts on the stepper demands.
Thanks for your input.
VB,
