Mach3 was cheaper than upgrading my CAM software so now I have to figure out how to configure Mach3!
I use stepper motors with 200 steps like everyone else so I need to know what some of you guys put into the "steps per unit" field to get yours working. Especially the Z axis numbers would be great.
I can't believe I pay for software and it has such terrible user experience compared to the free stuff! LinuxCNC may have only supported RS274NGC but at least its user interface was great for configuring. I think I spent like 20 minutes setting up LinuxCNC as a complete noob. Here, a year later I know so much more and I'm just lost with the Mach3 stuff. I have to make this work since its the only way that 4 axis is going to get used anytime soon!
So, any help or pointers would be great! Also, I know the ballscrews are metric but I want to set this up as imperial. Any pointers or actual numbers would be great. The function in Mach3 to move the axis and measure the distance returns a different number every time so either my gauge is wrong or I'm way out in the weeds on some other parameter!
thanks!
