Did you try running the machine with it?
Did you try running the included PARPORT/AXIS/AXIS_MM config ? Does this report warnings when running?
Make a config for your machine, set the base period to 100000, everything else at default, try running it and see if it complains about latency.

Best TTC3018 Pro CNC Router Machine: Is It a Good Choice for Beginners?

I’m considering a desktop CNC engraving machine for small projects, hobby work, and engraving designs on suitable materials. I’m looking for something compact that can fit on a workbench without taking up too much space. Ease of setup, engraving accuracy, software compatibility, upgrade options, and overall value for money are the main things I’d like to consider. I’d also prefer a machine that is manageable for someone who is still learning CNC machining.

Here are two options I’m considering:
TTC3018 Pro CNC Router Machine, Desktop CNC Engraving Machine

TTC3018 CNC Router Machine 3-Axis Engraving Machine Metal Engraver

www.amazon.com/CNC-Router-Engraving-Engr...rue&ref_=as_li_ss_tl

Both options seem worth considering, but I’m unsure which would suit my needs better. I’d appreciate advice from people who have firsthand experience with either machine.

How difficult are they to assemble, configure, and operate for a beginner? Is there a noticeable difference in engraving precision, stability, and noise during normal use? I’m also interested in how well the machines handle different materials, what limitations become apparent with more detailed projects, and whether additional upgrades are necessary.

Are replacement parts and accessories easy to find? If you have used either model, what drawbacks have you encountered, and would you choose it again?

I’m open to other desktop CNC routers in a similar price range if there’s a more practical option for a beginner.
Any recommendations would be appreciated. Thanks in advance!

I'm setting up an real milling machine with xyzab_tdr_kins kinematics.
To avoid unnecessary questions, I emphatically declare that everything is correct in my configuration, I made all changes on purpose, it was supposed to be like that, it works well and has no connection with the described below error.

Since this is a real machine, it has real parameters in the ini file.Unfortunately, the Z-axis travel is only 110 mm, but as it turned out, this was a bigger problem than I expected....
After basing it looks like this:
 
Then I issued some commands, which you can see in the MDI window.
 
So far everything works as it should, but after executing G12.1 miracles happen:
 
If you look closely at the pictures above, you can find the reason.

The explanation of this phenomenon is extremely simple.
Well, after a 90-degree rotation, G12.1 actually swaps the axes.
This is probably mathematically correct and works correctly in the simulator and on a real machine in JOG mode.
But when I try to use the g-code in MDI or in a program, this converted Z(abs) value is compared to the Z axis soft limits specified in the ini file, which makes absolutely no sense.
As you can see in the pictures, even an attempt to rotate by a very small value (here 1 degree) causes an error, although it is very far from the soft limits of the Z axis. Basically, it's even worse, because G0A1 here is a movement around the Z axis, the spindle is supposed to stay in place, and the error appears...

I only have reference sensors in the machine, I haven't planned any hardware limits and I don't want to install them because there are Ethercat drives that turn off when overloaded and report an error.
I also don't like the abandonment of soft limits, because they effectively prevent movement outside the working area.
Besides, the error is in G12.1 and it is this that needs to be fixed, not around the problem.

G12.1 should, in addition to what it does, disable soft limits (and G13.1 enable them again).

Good morning. I’m new to this.
I need some guidance regarding a Benchman machine; the PC board has failed. Could someone who has already handled this kind of repair please provide some advice?

Short update: I made a 3-minute video that goes through all 12 cycles - the form, the 2D preview and the G-code it generates.



Also new: the Windows version is now on the Microsoft Store (no more SmartScreen warnings on the installer). The Linux .deb is on the site as before.

Trial (15 days, no email needed): turngcode.com/en/trial/?utm_source=linux...utm_campaign=3min_en

As always, feedback and bug reports are welcome - especially from anyone running it on a real lathe.

Ive started using this yesterday as well... honestly, im rooting for it to get 90% as good as fusion, and hopefully 80-90% of the Manufacturing tab, that will bring linux into real world CAM finally.
I even was able to connect claudecode to it to design stuff via prompt. Insane how fast stuff is moving.

I don't think the Axis user interface has any provisions for multiple spindles. For on screen control of spindles other than the primary one you will either have to settle for using MDI commands or build a VCP to control the other spindles (such as PyVCP, GadeVCP, or QtVCP.)

Hello everyone,I'm developing a custom CNC controller on Ubuntu Linux with real-time capabilities. The core control system is being written in C, and I'm working on integrating EtherCAT for servo drive communication.I'm now considering the best approach for designing the user interface (HMI).My main questions are:

• Should I develop the entire application, including the GUI, in C/C++ using a native Linux GUI framework?
• Would it be better to build a modern web-based interface using React, with a separate backend communicating with the C control core?
• What architecture would you recommend for a CNC controller that requires reliable real-time motion control, low latency, and a responsive user interface?
• Are there any existing LinuxCNC components or libraries worth considering for this purpose?

My priority is to keep the real-time control layer independent of the GUI, while making the interface modern, maintainable, and easy to extend.I'd appreciate hearing about your experiences and recommendations.Thank you!

Unfortunately,  I don't know about Debian, I use Mint
and build kernels from source.

Hola, después de mucho tiempo. Finalmente he armado esa pc, bien antigua, hoy con 1024 megas de ram ddr, su procesador 32 bits, y por fin su ssd. Descargué el Ubuntu propuesto, lo instale, re bien, sin internet, pero cuando probé su latencia, dió unos valores altísimos , probé, probé y luego volví a instalarle Linuxcnc 2.7.14, pero al realizar su latencia, iguaklmente muy alto los valores, por ende no me sirve para utilizarlo. Sería tan amable de compartirme su hardware tiene en su Ubuntu usado por años, sin problemas?, sigo insistiendo que me tiene que servir ñeste viejo cpu, pero los valores no acompañan para nada. Muchisimas Gracias!...

How to install 7.x to debian 13 from backports repo ?

Quick Note: Everyone in the EU, looks like the USPS is charging me for prepaid Duties, Taxes, and Fees now on top of the postage.

Upside: Duties and Taxes will be prepaid.
Downside: I have to include that cost in the Shipping quote.

If you have a local dealer, please check with them first. Even used, International sipping and duties/taxes may make my listings cost prohibitive.

Mesa 7I95T has been SOLD, the rest is still available.
