CNC Fusion X3 Deluxe Kit Backlash Issues

[dneisler]

Just added a video on my site of my X3 moving at 120IPM. My first video, its not much. Waiting on some zero backlash couplers to arrive.

everybody's do'n videos, i guess now that i have my machine up and running, and i just happen to have a webcam out in the machine room, maby i outta shoot some vids.. i've seen mine move at the mach3 max of 270IPM.. pretty impressive....

[dneisler]

Yeah 270IPM is impressive, mine probably could go faster, but dang, 120IPM is way faster than needed. Its not like either of us are going to be able to cut at any where close to that :-)

I am using 425's for X and Y and a 640 for my Z. What are you using project5k?

all 3 are 500oz-in 3A 4 wire bipolars under gecko 203v's @ around 48V

no, i wouldnt ever be able to machine that fast, and its not to say that my machine will reliably move that fast all the time, you get out toward the ends of the travels and that 270 will stall... and if i lower the ramp speed enough to get past the stalling at the ends of the travels, then by the time its through accelerating it has to start decelerating or it would run off the end of the ways! heheheh

i am working on an idea about a much faster spindle, but thats in another thread about spindles.. thats really my limitation now, is RPM's...
