Wire foam cutter takes of on its own

Postby tomJohns » Wed Sep 16, 2015 5:59 am

We use a partially new MK2/4 as a cnc wire foam cutter. some times it runs profiles fine, but the problem arises when in some other times it will all of a sudden tumble across the cutting board on a zigzag manner somewhere in the middle of a cut and then it stops. Or it just becomes super slow. any ideas will be appreciated...
cheers

Electro Magnetic Induction. It is a thing. Google it.

You see, EMI occurs when some of the electric current and the magnetic fields around the steppers interact and distorts the process of the wire foam cutting in your case. At least I think this is what is happening here - I happened to encounter a similar problem as I was browsing around some months ago - I forget where it was but I will furnish you with the particulars when I get it.

Well, you could try making the cables insulated - I think this would help. Although I am not sure. Like I said, Google it.

Hey, EMI actually stands for electromagnetic interference. But you are correct on the sense of it being the cause of OP's woes.

Nice one, fellows! I have learned a lot today - here is the whole process boiled down to the dregs: YT :-)
All men dream-but not equally. Those who dream by night in the dusty recesses of their minds wake in the day to find that it was vanity: but the dreamers of the day are dangerous men, for they may act their dream with open eyes, to make it possible.
