I have an mpcnc that is sized to cut a full sheet of plywood. My intention for the machine is to use it just for 2D cutting. I will build a smaller one for milling next year. I purchased the hardware kit from this site, 3D printed my own parts and built a large wooden frame. I am using 18/4 wire to ensure there will be no problems with the length of the wires for this a large machine.
I realize I’m going into crazy land building such a large one. Especially using regular EMT conduit. But perhaps we can learn from my pain!
My wife is cool. I have this thing in our dining room over the winter! The plan is to move it into the shop (which I am renovating at the moment) in the spring.
It is mainly assembled and operational, aside from the Z, and I can move along the X and Y axi though there is chattering.
Question #1 : I cannot manually move in either the X or Y further than 1000mm … is this a firmware limit?
Question #2 : My hardware kit came with a spring … is this to solve backlash on the Z?
I’ve seen others use adjustable supports and I may go that route. Mine are all the same height and I’ve noticed that some are loose compared to others. I figured that having them the same height is probably a good thing as it would consistently limit flex. I’ll let you know how these work out once I’ve used them some more.
