General Mach Discussion / Re: Step Pulse Won't Save

I will try that , config menu and choose the save settings option does not break the cycle , the only thing that seems to break the cycle is opening the ports and pins dialouge after motor tuning.

The earlier version of mach 2.5 or so did not have this issue , it started when I upgraded to a more recent version , its not really a problem once you figure out how to stop it , just a little glitch as the original poster pointed out

I would think you need to change the number of pulses for unit of movement( 1 inch) in motor tuning. If the distance of movement has changed by a factor of six exactly you should be able to simply devide the number of pulses listed currently by 6.

I would love to be able to use the existing  encoder if at all possible, I am def not going to take it off with smooth stepper soon being able to utilize it

mine needs to be at 11 or 12 for the spindle motor to spin up to the correct speed, at a value of 5 I cant get the output to my VFD over aprox 3 volts, needs 10 for full rpm (1725). I am not sure exactly what the value I am changing is but a few months ago when i was going thru the VFD setup someone here mentioned trying a much higher value.

looks like about 5 1/2" is about as small as I can make it , the spindle is 5" diam where it exits the bearings and increases to 10" at the big air cyl that closes the chuck . There is a 6" diam cog that drives the qaud encoder sandwiched between the bearing housing and air cyl , I was thinking of pulling it off and replacing with slotted disk

I just spent a bit of time playing with mach 3 , The value will keep dropping until it hits 2 , but if you save the value you want and then open the ports and pins dialouge box it seems to break the cycle of dropping by one and stays on the last value before ports and pins was opened. Not sure why but it seems to work

Thanks  , yes the slotted disk is what I am reffering to .

it keeps dropping until it hits 2 on the machine I use daily

Is there any problem with a using 5" + diameter encoder disk with the C3 index pulse card from cnc4p

I have noticed the same issue with the step pulse value, if you enter the value you want , choose save setting and then close the motor tuning dialouge box it will save your setting but each time you open the motor tuning dialouge box that value will drop by one . I have it set at 11  and each time I open motor tuning it drops by one to 10 , 9 , 8 and so on , you just need to make sure you type in the value you want and click save axis setting every time you open motor tuning.
