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.

Tangent Corner / My Electronic Juke Box.

« on: February 15, 2016, 05:36:51 AM »

Just a bit of fun really but it always took me far too long to find the particular CD that I wanted to play in the workshop so I had an idea…
Based on the principle of the IPlayer/Ipod/Ipad I used a Win10 tablet (with some modified software) to become my electronic juke box. It uses it’s Wi-Fi to download the tunes from my CD’s stored in the cloud and it’s Bluetooth to stream the audio to my speaker system. Almost perfect except for two major problems…
1) Windows Update – With Win10 you can defer updates but you can’t actually turn them off and they do cause problems. The solution was to store all the music on the tablet’s SSD then disable the Wi-Fi. Surprisingly, I been able to rip some 80 CD’s to the SSD and it has hardly made a dent into it’s storage capacity – just another 100 or so CD’s to go and I will be there.
2) The tablet’s 10 inch screen size is just not big enough for my sausage sized fingers. I have tried using a rubber tipped stylus but I really need a larger sized touch screen.
To the rescue came this Win10 based, self-service, kiosk, which was used over the 2015 Christmas  period at the London Westfield ice skating rink - basically for just dispensing tickets. It has a 21 inch touch screen (just right for sausages) and can sync with my master PC for transferring over the completed music data base etc to it’s own SSD. Although it has it’s own ‘low level’, built-in, sound - the selected music is still streamed, via a Bluetooth link, to my sound system so it just requires a mains power connection to do it’s thing. I still have a bit of work to do but it looks good for sweet music in the workshop from now on.

Mach4 General Discussion / Re: Add a laser to my CNC

« on: February 15, 2016, 04:50:25 AM »

Hi Bob,

Perhaps all the more reason for motion controller developers to support the M62/M63 commands ??

In my case (as shown in the linked video) I am combining the A axis direction signal (a modified logic AND) with the PWM on an Output# (as a laser power control method this is described in a bit more detail in my Laser thread). As a result Estop turns off the Output# and also the laser (the A axis direction signal is not passed through without the Output# being active). I appreciate that not everyone would want to use this method but it is just one way of achieving the desired result when I only had limited tools available.

And how to mill so the object will not fall out when you mill it to the bottom

Most CAD/CAM software will allow you to create the Gcode with 'tabs' to stop the finished part from falling out. Another option would be to mount your stock onto the spoil board with double sided sticky ( as well as the clamps, if necessary ) that is usually enough to hold the finished part in place. There are also other options - as you are starting to discover, CNC is a never ending journey of learning.

Rather than repeat everything here, the Mach3 manual contains full details of how to go about its' configuration in relation to your particular stepper motor and your chosen micro-stepping. http://www.machsupport.com/help-learning/product-manuals/

Your maximum stepper motor current is shown as 5A and your stepper motor driver dip switches should be set to this figure (or just slightly less [4.45A]) - refer to your equipment manufacturer's data sheets for more details.
