It actually says "Pulsing too fast"
If you do an advanced search for this there are lots of posts to read (not too read ;-) )

Add (____________________________BLANK LINE) on your blank lines to maintain them as lines in MACH3

Thanks Tweakie!
I know the concept of a shaft encoder is old but the idea was a way to massively improve homing accuracy and repeatability in a way that would be accessible to everyone who's already added or is considering adding homing switches to their machine ;-)

I am cutting at 50% feedrate on mach 3 screen. I could not find a downcut bit in 1/8

That could be 50% of nothing or 50% of Light Speed, a percentage means nothing without a reference value ;-)

General Mach Discussion / Improved Home Switching Idea?

« on: April 03, 2016, 05:36:01 AM »

If we assume a machine with all limit switches on one input and a separate input for each home switch and wire it up with any old decent Normally Closed micro-switch at end of travel we get home positions but with accuracy and repeatability which is often dismissed by owners of pro systems and rarely proves good enough to pick up halfway through a finishing operation.

But what if we add a cam somewhere on each stepper shaft or ball-screw which operates a second switch wired in parallel to the end of travel limit switch for that axis?
The cam switch will operate once per turn but the home circuit will only open with both switches open, tune the cam switch to open/close a fraction of a turn after the linearly actuated switch is open and the accuracy and repeatability should be significantly better than is achievable with just linear switching.

Sound feasible?

I don't see the importance of CAM.

There isn't any if you want to manually code parts.

but there is a member whom has made it

He is using a PLC, essentially a PLC is an industrial automation computer and you would need to know what functions the PLC deals with, what software was written to do this and how the automation is handled from within Mach3, he's using Modbus to communicate with the PLC but his G-Code will have to include stuff to initiate this.
None of this is standard CAM output, you would be able to write your own Post Processor for a CAM system to support the hardware.
I think there are more learning curves in there than you might thnk ;-)

In BIOS as well as OS?

I built a new machine and used a ethernet board and I have not had any problems. I am thinking it was the usb board

Had you disabled all power-saving on the USB on the problem PC?
