Mach3 turn x axis moving 4 times as fast all over sudden
« on: November 24, 2013, 02:04:54 AM »
Hey guys,

i have the following problem. I start up Mach3 and i switch on "Jog" to move the axis by hand with the cursor button. I have setup everything correctly in Motor tuning and i was pretty happy until this afternoon. I was moving along the z axis and was getting ready to slowly plunge into my work piece and i noticed that the x axis was moving a lot faster than before. So i switched of the lathe and moved the x axis and its going about 4 times as fast as normal. I checked the motor tuning settings and retype everything about 50 times and nothing changed. After that i moved the Z around a bit for about a minute or two and all over sudden the x went back to normal settings.
This keeps happening all the time now. First i though the drive might be bad and i tested it with 2 other ones with the same result. The x position on the screen still moves slowly and is totally off the real movement. Its almost like it switched from 1/8 step to full or half step, although they are all set for 1/8 step with dip switches.
All this started today after i "accidentally" installed mach3 again. Not sure if that has something to do with it. I dont dare running any code at the moment since i don't want a 1/8 plunge ending up being a 1/2 one
Anyone ever experienced that? Any help is greatly appreciated

Seb

Never heard of anything like that and cant really think of what could cause it. If you attach your xml I will have a look through it to see if I can find something.

Almost sounds like your PC is switching frequencies ?

Intermittent noise problem on the X axis connector?

Cheers
