Hi,
Steve has made a very nice summary of those situations where backlash compensation can be benefical.
For a mill with high cutting forces its not going to help.
.2" of backlash, INCHES? Tell me that's a typo!
No its no typo....and yes at 0.25 inch per turn, its almost a complete turn. The brass yoke is that worn the remaining threads must be so thin they break out some day soon.
While from time to time I do give this machine some hard work mostly it sits a month between jobs. I work repairing welding equipment and we might use it for facing
or otherwise shaping some insulation or shaping copper electrodes for a spotwelder for instance.
Despite the backlash you can still do some pretty good and accurate work with it but it takes patience and practice. Software cant do it, I can, and I prefer
to call myself 'squishyware'.
