Hello,
I posted a little while back on the Lazy Cam Forum that I am having problems with my Z-Axis drifting. I thought the problem was mechanical but it wasn’t. I have an old oscilloscope I am using to look at the signals but without a test plan I am just looking at pretty signals without knowing what to look for. Does anybody have any suggestions?
Hardware & Software Specs:
Mach 3: Version R2.0.024
LazyCam: 2.00.032 Standard Edition
Computer: 2.53 GHz, 512 MB RAM
Drivers: Gecko G340 DC Servo
Motors: Brush DC Motor with US Digital Encoder
Machine: Homemade 3 axis Gantry CNC Router
Here is a copy of the Lazy Cam posting:
I have been having some problems with my Z axis. I use LazyCam to import a JPEG and convert it to G-Code. I load the code into the Mach 3 Controller. About half way through the cutting process I notice that my cutter is no longer in the material. It looks like the cutter has been slowly ramping in the positive Z direction. If I look at the Z axis during the engraving process it is moving up and down the way I would expect, but it must be slowly incrementing itself in the positive (upward) direction. However if I look at the Z axis DRO it is indicating a negative value which would seem to indicate that the cutter should be in the material. Am I missing a setting? I am confused. Any suggestions?
I am using the following software versions:
Mach 3: Version R2.0.024
LazyCam: 2.00.032 Standard Edition
Thanks.
