Extremely frustrated, with getting the x-carve to the accuracy specified in the spec of the machine.
I have followed all of the online guidance on getting the machine accurate and several third party one, and now im wondering If i just have bad parts in my machine…
So, Im consistently cutting smaller dimension than I specify, here is whats tricky, the machine has been calibrated, I can move it 700mm and is spot on and and will move 700mm back exactly to the original spot. after all cuts I will come back to my zero perfectly inline. It took me a while to realize this much. So my cuts are consistently smaller, but here is another thing that makes it tricky, its inaccurate in a scaleable way, but only to a point… The error will scale upwards but once I get to beyond say an inch in size the error will stay the same.
So far my trouble shooting has included…
calibrating the xyz steppers, setting belt tensions, setting vwheel tension, tightening pulleys. Replaing the router. adjusting the potentiometers. and surprisngly none of these made ANY difference to the slop im getting.
The one thing i discovered today is that if I go crazy slow, with a cut that takes a .003" pass going 2"/m… the cut gets more accurate. but is still loosing a .05" on a half inch circle. So now I feel like maybe the problem is the carriage on which the router sits. If i wiggle it it feels like the v-wheels have slop on their track… so have I a bad carraige/gantry? or is this just what t x-carve is?
