I'd like to launch a new industrial machinery business. My goal is to import and distribute high-quality, competitively priced industrial CNC routers built for the UK market. The demand across woodworking, signage, and plastics sectors for affordable yet reliable machines is massive right now, and the supply chain is fully ready.

Now, I need the final piece of the puzzle—the right technical partner. I am looking for a UK-based, independent CNC Field Service Engineer to join me as a co-founder.

Who I am looking for:
The Skills: experience with mechanical/electrical troubleshooting, installations, and servicing industrial CNC gear.
The Location: West Midlands or other areas.


What I bring to the table:
Full Technical Training: I will arrange deep-dive training on our specific router models, control systems, and electronics until you know them inside out.
Solid Hardware: A reliable product line utilizing with diferent options.
Zero Logistics Hassle: I handle all the backend procurement, factory management, and parts fulfillment.
Real Partnership: Shared equity and revenue potential from both machine sales and long-term service contracts.

If you’re a skilled engineer ready to stop working for someone else and want to co-build a reputable CNC brand here in the UK, let’s talk.

Please drop me a PM here on the forum to arrange an initial chat or grab a coffee.

Cheers. ]]> Telford 26 https://www.mycncuk.com/threads/16107-Looking-for-a-CNC-Field-Service-Engineer-to-join-me-as-a-Technical-Partner NEW MEMBER: New member interested in CNC and G-code https://www.mycncuk.com/threads/16106-New-member-interested-in-CNC-and-G-code?goto=newpost Mon, 13 Jul 2026 01:32:37 GMT Hi, new member, Interested in CNC and G-code and CNC software.

Interested in CNC and G-code and CNC software.
Currently writing free online tools for the CNC community.
If you have a dodgy piece of gcode you want help with, hit me up, mill / router / plasma cutter / laser etc. (Not 3D printer or lathe)

Thanks! ]]> New Member Introductions UltraNC https://www.mycncuk.com/threads/16106-New-member-interested-in-CNC-and-G-code Built a free G-code viewer with real cycle-time simulation. Try to break it. https://www.mycncuk.com/threads/16105-Built-a-free-G-code-viewer-with-real-cycle-time-simulation-Try-to-break-it?goto=newpost Sun, 12 Jul 2026 02:13:13 GMT I've built a free G-code viewer that runs in the browser. It uses real motion control algorithms the same kind as your CNC controller.

Set your machine's rapids and acceleration in the "Machine Dynamics" box to match your machine, or just leave the defaults.

Nothing is uploaded. The file is parsed in your browser and never leaves your machine, so you can paste anything.

What it handles: G0 to G3 arcs in all planes, canned cycles including peck drilling and rigid tapping, M98 / M97 / o-sub subprograms nested and expanded, dialect-aware G04 dwell (Fanuc milliseconds vs LinuxCNC seconds), G94/G95, G61/G64 blending in the time model, and optional S-curve jerk if you set it. Anything it can't fully model gets mentioned in the message panel instead of being quietly ignored.

The challenge. Throw your ugliest post-processor output at it and try to make it time wrong, draw wrong, fall over, or simulate something wrongly without telling you. A missing disclosure counts too. Find one and I'll fix it and credit you in the changelog.

The rules and the full supported-code list: https://ultranc.com/challenge/
The viewer, no signup: https://ultranc.com/gcode-viewer/

The screenshot below is the "UltraNC Sign.nc" demo, timed at 44:35. It's in the viewer's demo file menu, so load it and check the number for yourself, then bring your own worst file.

Free, no accounts, no catch. Tell me where it's wrong.

I have just replaced an ACME feed screw with a ball-screw on a Harrison milling machine, and in the process have had to remove the table feed motor.
A number of people have fitted NEMA hybrid servo motors as part of a CNC conversion. What I would like to do is retain a manual control along with a DRO readout but I am struggling to find information on how I can do this.

At the moment I have the original hand-wheel driving the screw directly. What I would like to be able to do eventually is to fit a stepper motor with a view to full CNC control and fit a rotary encoder to drive it manually. The only problem with this is I would have no idea of the cutter position.
Can I attach a DRO to the stepper driver and get a digital readout of the tool position? or do I have to fit scales?
If I have to fit scales can I use the position from the scales to drive the stepper motors position, and use a non hybrid stepper. If I use a hybrid stepper how do i account for any lost steps?

I have tried searching the forum but keep getting no results, so I am probably asking the wrong questions. ]]> Bitterend https://www.mycncuk.com/threads/16101-help-please-jst-getting-started FOR SALE: Warco GH Major Milling Machine https://www.mycncuk.com/threads/16097-Warco-GH-Major-Milling-Machine?goto=newpost Fri, 26 Jun 2026 10:50:38 GMT Sold!

I have a developing problem, sometimes the machine jitters like it’s catching up with data, other times more commonly mach3 loses connection with cslabs and it stops mid cut. I am using stepper motors. The jittering occurs on large complex 3d NC programs, mach3 losing connection is random when it occurs.

I am using a windows xp laptop and connecting via an Ethernet cat 6 cable. At first I thought it was the Ethernet ports - poor connections. So I replaced my interfaces with the machine with screw down Ethernet connects made by Neutrik for microphones etc, also a new cable which is shielded ( last on was to) The problem hasn’t gone away.

I cannot seen to find much information online about setting to tweak. Most popular suggestion was to use cslabs interface instead of mach 3.
I have rebooted my laptop a few times and cleaned all the contacts in the data path, so I am now not sure what to look at next. I haven’t changed any of the settings from those Dean helped me put in 9 years ago.
Any tips to resolve this would be appreciated ]]> General Discussion Stressedwoodman https://www.mycncuk.com/threads/16092-Problems-with-mach3-and-cslabs-controller-jittering-losing-connection-frequently
