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

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
