Russ and Brett; i bought these off ebay the seller is IMSRV ,i think it stands for Imservice. i'm looking at the page i printed off ebay it says each revolution of screw moves .5 inch linearly.
accurate to.009 inch /foot.  it says 1/2-10, is that 10 pitch?  won't that be .100 x 5 =.5 ? by all means check em' out on ebay . i don't want em' to fool me. richard.

thank you,  Chaoticone, the lead is .5 " per rev ,it seems like that would be a 2 pitch , also the spread sheet has a default  value of 10 in the micro stepping window, i am not familiar with that value. shouldn't it be something like 1/8 or 1/4? thank you very much richard .

gentlemen; i was machining  a guitar in 2" blue styro foam  when mach froze, i had to close mach and reload and all was fine. i was past half way the code when it froze, i was doin' 120 ipm. this the second time this has happened. i built my machine, it's direct drive, 5 start,hobby cnc board and steppers, it's pulsing at a little over 27k, 1/8 micro step,i think my steps per is about 3200, i really can't get my steps per set right because it moves to fast to read the dial indicator revolutions. any way to slow it down? thank you for your help, richard stanley.

General Mach Discussion / stepper squealed

« on: February 15, 2013, 02:12:35 PM »

dear gentle men: i was cutting blue foam on my new home built router, all was going fine when a stepper let out a loud squeal and then ruined the part. is this loosing steps?
i,m trying to set my steps per unit I'll use my dial indicator  today.
what do you think happened? thank you very much, also since all 3 axis are using 1/2" single start 10 pitch acme screws , shouldn't the steps per be the same on all 3 axis? 
thanks again, Richard from watts, OK. out.

Chaoticone; there is no substitute for experience! I put in a value 100 in the debounce, this system seems to be operating at more 29khz. any way i just completed a dry run of the road runner with router running but no tool installed. went through it with out a hitch. thank you very much, richard.
