If you do not have your machine tuned correctly then the results obtained are unlikely to be satisfactory.

In both videos it is evident that your Acceleration value is far too low.
In the second video your axis is stalling indicating that your Velocity setting is too high.

I think you need to set-up your Motor Tuning for optimum Velocity and Acceleration for each axis. Page 13 of the Mach4 manual gives more details.

General Mach Discussion / Re: Pending signal managment on mach3
« on: June 04, 2020, 01:49:49 AM »
Mach3 was never intended to be operated in that manner but it does support the M1 optional program stop. This command could be linked to an input pin so that Mach3 could be toggled between start and stop by an external signal.

I am sure Mach4 could be operated in a similar manner.

General Mach Discussion / Re: How to add a second input to an E-STOP?
« on: June 04, 2020, 01:41:48 AM »
If you have a spare input (pins 1-4) then one of them could be used.
You need to first check the voltage levels from your 'spindle fault signal' to make sure it is suitable for connection to the G540 then the Gecko's input pin could be configured in a similar way to a limit switch and when triggered will operate Estop.

Hi Glennlee,

I don't think any updates will cure the problem (updates often create more issues than they solve) but re-installing your existing version may be beneficial if any of the old files have become corrupted.

Suddenly, mysteriously, in the exact same machine with the same wiring, Mach 3 version 3.043.062 cured the random estop triggering. 

Hi Ken,

Thanks for taking the time to explain your unrequested Estop solution.

(Unfortunately, back in the day, version .066 was developed for one particular motion controller manufacturer and it did not play nicely with the ESS. The Warp9 website does refer to this and recommends version .062 for use with their ESS).

Yes indeed sir the ESS will work with a any CNC machine using step and direction drivers and operated by Windows OS.

Like the other quality motion controller manufacturers, the ESS has excellent manufacturer support backed by an active forum where any problems users experience are quickly resolved. Please check out their website and forum for more details;  https://warp9td.com/

Please bear in mind that Mach3 is now obsolescent and although it still has a great many users (including myself) third party support is now aimed at its successor Mach4.

I can't recommend any particular motion controller because they each have their own merits but as I mentioned above one that I use is the Warp9 ESS which can be used with and has plugins for Mach3 and Mach4.

Hi Peri_95,

It is not a Mach3 bug otherwise we would all be breaking router bits  ;D

My advice would be to bin the cheap Chinese XHC card and fit a quality, US or EU manufactured, motion controller - it will save you money in the end. Selecting a motion controller that will also work with Mach4 would perhaps be good for the future.

(There are a few different motion controllers to choose from but one that I use is the Warp9 ESS).

In Config. / Ports & Pins / Motor Outputs,  change the Dir Low Active state of the axis you wish to reverse direction. Apply the change.

G-Code, CAD, and CAM discussions / Re: Loop-d-loop G41
« on: June 01, 2020, 10:47:42 AM »
Hi John,

Very nice looking machine.
You are using the latest / best version of Mach3.

There is something not quite right dimensionally with your Gcode file but I am not clever enough to spot where the problem lies. I suspect that Mach3 thinks there is not enough room to apply the cutter radius compensation (lead-in) so it takes an alternative path.
Incidentally UCCNC also reports cutter radius compensation warnings when your Gcode file is loaded which may confirm a Gcode dimensional error is present.
