You will lose resolution but not accuracy...
Leadscrew Pitch Tutorial
I just changed from 16TPI to 10TPI and then even further down to 2TPI.
My x and Z axis are 14 TPI. My Y is 10 TPI. Would my CNC be more accurate with a 14 TPI on my Y-axis?
Too, my CNC works very good but my God... it is loud, especially when the Y axis is in motion. I suppose the wood framing along with the stepper motor gives it the roar. Does anyone have the problem?
Thanks. What about that roar?
Your x and z have a theoretical accuracy of 3 ten-thousands of an inch (approximately) assuming you are using steppers, and you have to ask youself if you routinely hold these tolerances in the parts you make, or even, are your leadscrews are that precise or your backlash is smaller than that...
I have not lubricated them. I will try that. thanks
