Motor is directly connected to chuck,no transmission...Also,it makes 4 steps to make 1 degree,is this minimal movement for this motor or it can be set to make smaller steps for better detail?
This is from the mach3 yahoo group,
Config> ports and Pins> motor output> enable the spindle and enter the pin
numbers for the indexer step and direction pins.
Don't forget to click on apply.
Next, click on Config> ports and Pins> Spindle set up> put a check mark in"Use
Spindle Motor output" and another check mark in step and direction.
Last go to
> config> pulley set up
and provide the necessary info.
Then in your G code you will need the M3 command and the S value.
Such as S 200 for 200 RPM ...........................................................i didnt get if i set spindle pins do i leave my a axis pins same?and what pulley is right,and do i have to set ports for spindle.what should i set to be able to make a ring ?and can my motor be set to make more than 4 steps per degree?
Just wondering but when you ask "how to set A-axis to move continuously,not in steps?" do you really mean "continously" or do you mean you want more resolution. I think maybe there's a misunderstanding going on here - at least that's what I get when I read your second post.You are right,i realized that now too,well,I would like to have better resolution,smaller steps when i do toolpath along x as i do now, I also want to be able to execute toolpaths with 4th axis that are perpendicular to x axis.For that i need 4th axis to move smooth and not in steps.I gues smooth is right word ,not continuous like lathe.I did set my 4th axis as spindle but than i cant use it as A axis,so now i changed Steps Per in motor tuning for A axis from 4 to 2000 and now i have smooth movement but now degrees dont match in DRO as RICH said.So,is it possible to calibrate degrees from DRO with actual degrees?
how many revolutions does your motor turn if you command G0 A360if i put "4" in Steps Per it makes 1 turn (4 steps for 1 degree,so it makes 1440 steps). ..if i put 8 in steps per-it makes 2 turns,if i put 2000 in Steps Per it will make....500 turns. ...problem is that when i set it on "4 steps per" the movement is in steps,not smooth,and i have heavy chuck and its shaking after every step,..but when i set it on "2000 steps per" the movement is fast and smooth but it dosnt match the degrees in DRO...
Then to summarize - I'm afraid that's it - your system has a resolution of 4 steps per degree and as I've said - there is nothing you can do about it other than gearing.how many revolutions does your motor turn if you command G0 A360if i put "4" in Steps Per it makes 1 turn
