Mach4 General Discussion / My tool runs off
« on: October 12, 2020, 08:02:52 PM »
Sometimes my tool will appear to run off in a random direction. The actual tool path on screen shows that the tool left the programed path. This happens even when no one touches the controls and is a program I have run a dozen or more times. It just seems to happen at random intervals. Its almost like a software bug. It happens rare enough that it hasn't been a major issue but it just ruined a good drill and part that was 1/2 way done. Now I'm irritated. I have a home modified mini mill converted with Automation Technologies electronics, a UC100 motion controller, and Mach4 software. Any ideas?

Mach4 General Discussion / Uneven Cuts
« on: August 17, 2020, 12:32:55 PM »
When I run a CNC program sometimes the cut comes out lopsided almost as if the Y or the X axis "slipped" and didn't travel as far as it was supposed to before the next cut. Is this a hardware issue or a software issue? It only seems to occur infrequently and on larger cuts?

Mach4 General Discussion / Re: Axis reverse

Already tried that with no luck. I just reversed the wiring. That seemed to do the trick.

Mach4 General Discussion / Axis reverse
« on: July 15, 2020, 05:49:45 PM »
I have a Harbor Freight Mini-Mill that I converted to a 3-axis CNC machine using a Heavy Metal ball screw conversion kit with Automated Technologies electronics. I use Fusion 360 for design and have installed the Mach4 post to my local library from Autodesk's website. I have made a small bottle opener to test. Every time I run g-code the part comes out mirrored. My y-axis seems to be inverted. When the y-axis is supposed to be traveling in the y- direction it travels in the y+ and visa versa.

Mach4 General Discussion / The scale when cutting is off.

I have a Harbor Freight Mini-Mill that I converted to a 3-axis CNC machine using a Heavy Metal ball screw conversion kit with Automated Technologies electronics. I use Fusion 360 for design and have installed the Mach4 post to my local library from Autodesk's website. I have made a small bottle opener to test. Every time I run the g-code the bottle opener comes out about half size. The scale between my design and the actual part when cut always seems to always be off and it comes out shrunk. My machine setup units are set to inches and my unit mode is set to metric. Could it be my motor settings are off?

Motor Settings:
  counts/unit; 40960.0
  units/minute; 35
  units/sec^2; 0.49

My motor has 200 steps (1.8deg.) each and has a 128 microsteps.

My math: (200*128)/(0.625)=40960.0 counts/unit

Never mind. You mean the through the configuration tab, yes I did that.

How would I go about making sure?

I also downloaded the plugin for the motion controller and have it enabled.

This is the break-out board: https://www.automationtechnologiesinc.com/products-page/motion-controllers/c10-bidirectional-breakout/

I am new to Mach4 and trying to use it to control a Harbor Freight mini mill with an Automation Technology CNC conversion kit. All boards, power supplies, stepper drivers, and motors show green or have current. In Mach4 the machine diagnostics tab also shows green output to the motors. I followed the PDF instructions from ArtSoft as close as possible. Despite this I cant get any movement on the mill. For some reason there seems to be no signal getting through despite the green status lights and current to the motors. I have tried to manual traverse through Mach4 about a dozen times. Any input is appreciated!
