CS-Lab / CSMIO/M and Mach4

« Last post by Michaelc on July 13, 2025, 11:57:22 AM »

Hi, can anyone help. My set up, Windows 11 worse luck, demo version of Mach4 turn, and CSMIO/M controller. Now information is thin from all companies and I have found nothing about resetting the network adapter to the settings the CSMIO/M controller needs. This was so easy with windows 10.
So after a hour trolling the internet I found some information on changing the network adapters address. But it must of been for an older version of windows 11 because it looks like I have done it correctly but the LED light on the controller is not on and Mach3 can’t find the controller.
Can anyone help me out in simple terms. Thanks

Mach4 Plugins / CS-LABS CSMIO controller and Mach4

« Last post by Michaelc on July 13, 2025, 08:54:30 AM »

Hi, can anyone help. I am trying to get my cnc lathe working. So far I have downloaded a version of Mach4 demo version. And the firmware for the CS-LABS controller. I have seen the CS-LABS controller in Mach3 plug-ins and ticked the box to use it. I unticked all the other options bar keyboard. Save all the above.
Turn off the system. Now on start up the can’t find controller shows up. And nothing moves.
I am using the Lang cable that came with the controller.
What am I doing wrong, I have set the IP address and mask to the settings CS-LBS listed.
Can anyone help me out here.
Thanks

General Mach Discussion / Strange Circles

« Last post by Spandex on July 13, 2025, 05:18:15 AM »

Hi guys, I created a part in FreeCAD. When I start Mach 3 on the same workstation that I have FreeCAD installed on, everything appears to be fine. When I transfer the .nc file to my computer connected to my CNC machine, I suddenly see strange circles. Does anyone know what might be happening?

Mach4 General Discussion / Re: Mach 4 Thread Milling

I downloaded a program from  https://www.chestnutpens.co.uk/misc/home.html some time ago which works very well.  However currently Norton is blocking access to the site as there is a certificate problem.  The site owner modified his internal threading code so it could cut down from the top to allow the use of a standard tap (with all but one of the cutting edges ground off).

Mach4 General Discussion / Re: Mach 4 Thread Milling

Hi,
I work with automotive instruments and on occasion require very small screws. The smallest I done successfully is a  13BA thread, which has a major diameter of 1.2mm
and a thread pitch of 0.25mm or 102 TPI!!

I was lucky and got off EBay five new Kyocera 98M11-0250LFA1 threadmills for $15USD. They are 1.1mm dimeter with a 0.25mm clearance, two flute. I could and did the external
thread of the screws above at 1.2mm major diameter. I made them in 316 stainless with a 3mm thread length. They were for a classic Jaguar tachometer from the fifties.
The smallest I could do an internal thread with these ultra tiny endmills is 1.4mm, but still pretty damned small!

The trick is to use a large number of very shallow passes otherwise the tool flexure beats you when it does not break the tool outright. That in turn requires that your machine can
do circular interpolation with micron type repeatable circularity. My machine made these screws and measuring with a micrometer found a ovality of about 0.02mm, which I thought was
pretty fair.

Hi,
I use Fusion and it has a perfectly good threading toolpath feature.

Is there a Wizard for Mach 4 for thread milling? If no wizard, what is a good way to generate the g-code for milling an internal thread on a mill using a single form threadmill?

I have mach4 V. 4.2.0.4517 on windows 10 64bit. ESS smoothstepper to gecko drives
Mach4 only shows readout windows for X Y Z, not sure, maybe it used to have A.
How do I go about getting a display for A axis?

Hi @Dotyman and @graphicer82

Thanks for your sharing. Would you like to release a DarkScreen ScreenSet support 5 or 6 axis?

Thank you
