Just one further point...

How are you turning your laser on/off ?.   If you are using the M3/M5 or M8/M9 commands then you need to check out the M11Px/M10Px commands as that will make a much better job.

You can download Mach3 from here;  https://www.machsupport.com/downloads-updates/main-programs/

(Because of Pirate License distribution this forum does not support any DigitalDream products).

General Mach Discussion / Re: Loosing steps Add a second Y axis DRO for mach3

Obviously you did not get the answer you wanted to hear 

If you have proved that the problem lies with just one axis stepper driver then the best solution would be to replace that driver.

If, for some reason, you cannot do that then reduce your Velocity and Acceleration settings (as mentioned above) to a figure that the problem driver can handle.

Overall your DFX to Gcode is doing a very poor job and I suspect this may have been caused by gaps in your vectors.
Anyway, I ran your DFX through Vectric Aspire and have attached the Gcode file for you to test (you will need to edit the Gcode (use notepad) to set your offsets, etc.).

General Mach Discussion / Re: Mach 3 random EMO after installing new motor and VFD.

Sounds very much like electrical noise.

VFD's are notorious and their correct screening / grounding is extremely important. No one solution cures all so a forum search will give you plenty of options to try.

The general unwritten rule for reliable machine operation is to find the maximum Velocity (in Motor Tuning) at which the motor (or motors) start to stall then reduce that figure by at least 25% and save the changes. Repeat for each axis. Then perform a similar operation with Acceleration. (Overall the higher the Acceleration the better but reduce it, if necessary, to stop the machine shaking when performing short movements).

This will reduce the maximum feed-rate available to the Gcode and in your case it will probably be around 150 ipm.

Mach4 General Discussion / Re: Mach 4 on a Millright Mega V: What do I need?

Just a suggestion...

Mach4, the Warp9 ESS motion controller and the C11G breakout board should meet all your requirements. Perhaps check out the Warp9 website for more details.

Mach4 General Discussion / Re: Serious problems with G76 cycle in Mach4 Lathe and CSMIO IP S

We have a Mori at the shop that threads all day every day.  Threading is a motion controller dependent function.  For Mach, we treat G32 moves (the basis for all threading ops) as a regular feed moves.  But we mark them so that the motion controller can sync them with the spindle.  There is nothing else Mach can do, at this point, because the motion hardware has to do the real-time stuff.

Hi Steve,

Just out of curiosity which motion controller are you using with your Mori and which version / build of Mach4 are you using with it please ?
