This is for a spinning lathe application all points have to be taught. the Jcode is very promising is there a way to have mcodes recorded with the file?

Hi All,

Ive been searching and trying a few diffrent things to do a Jog and teach, I need to record positions as the jogging happens. So far what i have tried has not been completely succesfull. I also looked at the copycat wizzard. Doest look like it actually teaches as you jog. Anyone have any ideas?

Rcazwillis,
   How did I miss this one? Will you post the files and any info to help. That is really neat. You don't have a short video of it running do you?

Brett

wouldnt mind seeing those files as well

Actually the arc voltage is only being used to determine height when cutting and is just the voltage the plasma unit is cutting on. the first "touch off" on the metal is a function usualy of the cnc controller.

Havent seen any touch off's work that way. I think you might confuse pilot arc with touch off. Ohmic sensing is usually done trough the cnc control and really has nothing to do with the plasma unit. And many commercial cnc plasma units have a secondary switch as a fail safe, or for cutting brushed stainless that has a plastic layer on it.

You did not specify a size, so all I was pointing out is that the smaller the cut the more chance of greater errors.

In point 1, I was saying, cutters may cut over size, not that they are over size. (I probably didn't word it right)

Graham.


All said and done we both really mean the same thing, the problem is though that we think from diffrent corners of the room ;D

or something like that. I guess it would be good to post a set a rules on this?

Hi xjdubber,

I will apologise now for what I am about to say.

Don't apologise  ;D

Agree with you on every point, except for the first (and some others:)). Im sorry but I've never seen an over size cutter yet? as for the rest, I agree but then those points should already have been taken care of before setting accuracy. As for the acuracy on the ballscrews that really depends on how new they are. Also squaring the spindle is not going to change the lenght of a cut. On your point #4 what do you mean 1" even normal size digital calipers go up to 6", You think i would measure error out of a 1" cut?

I have setup 6'x20' routers, that run anything up to alluminum that hold tolerance of .005 over 10 feet, so far the way i do things has been working for me ???

well, when i check accuracy on a machine I dont check it over long distance, I will go and cut something that i can measure with a very precise measuring device (like digital or dial calipers, i still rather use digital). Also remember that when cutting somethin with a milling bit, say if your using a .250" bit the bit doesnt have to be ".250 it can be smaller (wont be bigger though). If you have any double flute milling bits i would do a test cut with that because you can actually measure the diameter. Anyways thats what i would do.

edit: after reading that i realized I have to add that after checking over short distance and tuning. I then would check over long distance. I gues you could do it with a precise steel ruler (starret or something). If it looks dead on it should be ???
