Hi, If you are able to, go back to the original way you had the machine, with the original profile, and confirm that the only problem is swapped X an...

Great to hear that - just shows how accurate the machine can be if properly set up and adjusted.

Evan Could it be that the milling cutter is not running true - if my visualisation is correct a wobble of .07mm will reproduce what you are seeing....

Hi, I made my own from scrap wood so as to mill small printed circuit boards, and used a small vane type vacuum pump to get a good vacuum. All the...

If your computer is dedicated to UCCNC then go through the MSCONFIG startup and services menus and stop anything that isn't strictly relevant to your ...

You'll need to tell Mach4 all about your machine - I can't help with details of Mach4 as I use UCCNC. If you have a UCCNC profile for your machine...

If you are going to have to upgrade anyway to work in 3D, then give serious consideration to UCCNC. Not only does it work very well, but is is easily ...

Hi, Your 2N2222 is fine for the job - specified at 30V Vce and 800mA Ic. Zener diode provides protection against inductive spikes - I've sugge...

UCCNC defines operations in terms of units - without actually defining what units are in use. Standard Stepcraft profiles use mm as the basic unit, ...

Check your units - you've probably drawn in inches, cut in millimeters (25.4 : 1).

Hi, The line driver IC's are type SN74HC244 if I remember correctly - the device data sheet specifies an output current of 6mA both sinking (at Vol...

That was quite an ambitious layout for a first attempt!! Getting the FR4 flat is, as you found out, critical to getting a proper depth everywhere. ...

No need to do that - capability is already available in Eagle!! Draw the outline of your board using the "wire" command and place on layer 46 (mill...

Hi Use the .DXF output format - this imports straight into UCCNC. The basic UCCNC software can be downloaded for free and run in simulation mode...
