General Mach Discussion / Re: 6 Axis CNC MACH3 Engraving Machine Interface Breakout Board USB PWM Spindle

« on: February 16, 2016, 11:47:52 AM »

This board is connected to your PC's LPT parallel port with the appropriate 25 way cable. It also requires a 5 volt supply and this is intended to be achieved with a suitable USB cable. The Outputs from this board are connected to your individual stepper motor drivers and the attached document details the pins to be used. The document also identifies the Input pins to be used for Estop etc.
Please refer to the Mach3 maunal for full details http://www.machsupport.com/help-learning/product-manuals/

It sounds as though your Acceleration settings are too low (Config / Motor Tuning).

You have a belt geared reduction to your axis lead screw therefore you need to count the teeth on each pulley and use the formulae  Driver/Driven  to calculate the reduction ratio. Then measure the pitch of your leadscrew and use the information you now have in order to calculate the 'steps per unit' for the axis - this figure is then entered in Motor Tuning.
Please read the Mach3 manual - it is all explained there. http://www.machsupport.com/help-learning/product-manuals/

Sorry but your .xml did not post correctly so I am unable to test your set-up here. If you post it again it will have to have a unique name (i.e. Jamie2.xml).

Perhaps more curiously, when I FIRST start Mach, the actual pulse frequency is a rock steady 25,324. However if I close and restart, this drops to a rock steady 24,397. If I close and restart again it's rock steady at 23,674. Closing/re-starting from then on has no further effect and it remains at 23,674. If I re-boot then the whole (3) cycle will repeat exactly. Just one of those Mach3 things I suppose.

How on earth you discovered that beats me - it appears that the more I learn, the less I know about Mach3.

They used to be such slender and dainty little pinkeys but now that I have turned 50 they have become sausages - C'est la vie.

Ok, I got Tangential settings working better than I thought they would. I'm using it with a wire feed welder so I will have to get it to work without continuously rotating so it won't rap up the cords. Is there a way to do this? my a axis soft limit was set to 0-100 and it was still a continuous rotation.

If you attach your .xml file - the one from your Mach3 folder named <your profile>.xml (typically Mach3Mill.xml) I can take a look at your settings and maybe suggest a way. Copy and rename your .xml file to Jamie.xml then use the Reply button and select Additional Options to attach the file.

Mach4 General Discussion / Re: Mach 4 V2 Windows 10

To re-enforce what Don has said – with Win10 you can only defer updates, they cannot be turned off and from recent experience they will cause problems. IMO it is always best that the PC running Mach is never connected to the Net, even momentarily (I was surprised at how quickly my PC could download updates when my back was turned).

Your motor step size is 1.8 deg. (200 steps per revolution) and I would suggest a micro-step size of 10. This equates to 2000 steps per revolution and the dip switches from 4 to 8 would be set OFF, OFF, ON, ON, OFF which is exactly as your picture shows.
