General Mach Discussion / Z axis incorrect

« on: February 06, 2015, 08:06:20 AM »

hello everyone
iv dusted off my old machine and am going to have another go at trying to get to know it better
with a few trial runs iv found that i am loosing depth of cut to what i have programmed. ie programmed to cut to a depth of 6mm but actual final cut was only 4.24mm
process of elimination.

 i first check the Z movement (distance) in mach to the actual movement (distance) of the spindle.

i set the base of the spindle 55mm from the bed zeroed the Z axis and then lifted the spindle 45mm on the z counter on mach
that should have ment that the spindle should be a total 100mm from the bed, it wasnt, it was 89mm off the bed, a loss of 11mm
the machine is a 6040 chinese cnc
according to the specs sheet the ball screws are dia 16mm with a pitch of 5 mm
the motors are 387 oz motors from Homann supplies (with a lot of outside help i changed the moter rewired and fitter G540 stepper controlers to it)
the info/help i am after is what should the correct configeration be, for this setup, and were in mach do i change the settings
thankyou in advance for any feed back that maybe provided.
cheers Tony

Gentlemen
Thanks for the reply
Thinking after I logged post I should have elaborated a bit more.
It has both a multi pin port cable and a USB cable coming from the computer to the controller,
I've put a multi meter on the USB cable and have the required 5 volts  @ pin were goes into Break Out Board.
I've taken the cover off the controller, the indicator LED on the BOB is lit green for healthy, as are the LED 's  on each of the stepper boards
But the red LED is also lit up on each stepper board
Thinking there might be a bug in the system I uninstalled mach from the computer hard drive and reinstalled reconfigured all the motors etc as per the manual and nothing has changed
Am on IPad at the moment  so cannot post a manual or photos, when I can get back near my home  computer I will endeavor to find and post
I know from other cnc forums I've looked at that the Chinese wiring etc isn't that great, but I've only had the machine moving for about 1 hr max, one would have thought it would have lasted a bit longer

Thanks again for any feed back
Cheers Tony

Hello everyone
Some time ago I purchased a 6040 CNC
Finally put it together and started learning how to make chips ( with some success )
When I went to start it up yesterday, I found there was no signal getting from Mach to the controller
I can hear the magnets engaging in the steppers
When I use the jog option there is movement on the screen counter
What I carnt work out is, it was working when I shut it down last weekend  but nothing when I started it up again yesterday
Is it possiable the the multiple pin cable or USB cable failed on shutdown or start up

Thank you in advance for any feedback
Cheers Tony

Thank you for replying

I should have mentioned that from the onset
