Welcome to the forum Bill.
BILL, I use MACH3 to tune my steppers using xp and 25 pin serial connection. I t sounds to me the steppers aren't tuned in.Hi
I’ve got an older cnc router (24x24) . The motors are fine and the ball screws are good.
I bought it new and it’s been on a shelf in the garage for at least 10 years.
My problem is the controls. One day it’ll work ok, next day the motors move choppy.
Sounds like a machine gun. I’m getting very frustrated with it. I’m hoping this is a
common problem with a simple solution but if it isn’t, could you suggest what I need to do.
I’m using a computer with Windows XP and a 25 pin printer cable connection. If I have to
replace everything between the software to the motor control could you tell me what I need.
I’ve got the Cut 2d & Photo V Carve software and I’d kinda like to use it. Bought the software
in 2014. I’m recently retired and have some time to play.
Let me know.
Hi DavidHi Bill - you posted this same info in July last year and received some replies, suggestions, etc. Did you try any of those?
You could delete the post from July. Hopefully someone will respond to the updated one in the CNC subforum.Ok, generally you just go back and add to the thread you've already started rather than re-post the same info, especially since there are replies to the original post. The original post/thread can easily be moved to the CNC subforum.
We don't need two with the same info so do you want me to merge the two or delete one?
Okay Bill, let's start at the beginning. What kind of CNC did you buy? What kind of controller/software did it originally come with? Did you check all the connectors and clean them up?
Hi MEBCWDOkay Bill, let's start at the beginning. What kind of CNC did you buy? What kind of controller/software did it originally come with? Did you check all the connectors and clean them up?
Hi Bill. It sure sounds like electrical connection problems. You had a suggestion to clean the connectors and that is what I would do. I would pull every connector, inspect for tarnish and reseat it. Look at the pins on your DB25 connector. But also check your stepper motor connectors. I've had a flaky connector on one that made for some choppy motion.It has to be the software. I loaded the Mach 2 disk and rigged up a pencil to the Z axis and it worked pretty well. See picture (my wifes name is Heidi) .Next day I started it back up and it ran choppy.
I've tried a couple different computers and got the same results.
