Gecko G540 Trim dajustment
« on: February 12, 2010, 08:00:27 AM »
Does anyone know what this adjustment is for?  I have looked all over trying to figure out what it is supposed to do and cannot find any information on it.  I am not sure if I need adjust or not but first I have to find out what I am adjusting,

I presume it will be the same as on the G201 drives, the 201 manual details how to adjust if I recall (been quite a few years :) )

Found it, thanks Hood..........

I have one more sort of related question.  The lead screw being 4 turns per inch if I were to change that to 10 turns per inch the stepper will have to turn faster to move the same distance have I imporved the accuracy.  Maybe a better way to phrase that question is "does the lead screw thread per inch have any bearing on the accuracy of the move?

Hood's having a break. ;D

Yes accuracy improved or actually resolution, but speed slowed

4 / 10 = 40% decrease in speed, 40% increase in resolution

10 TPI for a mill

4 TPI for a router

All other things being equal

Thanks Phil, I sort of thought that but for a router I think the 4 TPI is probably the right way to go.  that is what I am runningbut have to do some major work on the drive system for more reliability and thought if I need to change them now is the time. 

I have couplings connecting the motor to the drive screw and they are split tubes with set set screws at each end and have a tendency to loosen up I have to fix that ..... I am looking now for a better coupling arrangement.

The couplings I am using now are Single Split Couplings
