Thanks, I think so too, but I had started to doubt it.

I think you will be fine, CNC machines rarely use full power and its highly unlikely you'll have all 3 motors at full power at the one time.  For example, the Z axis is only likely to use full power on plunging and then your X & Y are not moving.

Hi Aciera,

you are right, but i see almost any buttons of my keyboard, i can not figure out how tog et the rest of them.
Another problem is, when i press Button "Z", the menu in LinuxCNC shows up, because "Z" sends "F10" ( or was it F11 ) which brings up the menu. Another Axisbutton toggles between Windowmode and fullscreen of LinuxCNC UI, which is not what i would call a reliable system..
So i think i have to remap the keys send by my keyboard, or is there another solution to this problem i don't know about?

Thanks in advance, Greet, Tom

Hi Tim if you can post the Gerbers or Kicad that would be useful since Riocore is a open source project.

Cheers
Kam

I think github.com/LinuxCNC/linuxcnc/pull/4453 alleviates the issue, testing on machine needed for anyone available to do so

had a stab at #3455 as well github.com/LinuxCNC/linuxcnc/pull/4453
also check
github.com/LinuxCNC/linuxcnc/pull/4441

Dear meister:

item.taobao.com/item.htm?abbucket=19&id=...%7D&xxc=taobaoSearch

This is the link.

1.I am not sure if it is appropriate to post my product link here; if not, I will remove it.
2.I’m not a merchant; I’m just a DIY enthusiast. In my spare time, I make small items and sell them in my little Taobao shop. When a customer from China makes a purchase, I get a notification via the Qianniu app; the order includes a Chinese shipping address, and after paying about $1 for shipping, the buyer receives the item in a few days. However, I have absolutely no idea how to handle orders with foreign addresses. I’ve had English-speaking customers place orders before, but the delivery addresses were still within China, so I assume they were likely foreigners living there.
3.I would be very happy if someone could check out my little shop.

No, depending on efficiency, 4.7KVA is roughly 4-4.5KW, and your motors/drives will use more than 1.5KW at full power.
Still, it will work fine, do not worry about it.
1. chances are you will never have all 3 motors art full tilt at the same time,
2. even then the transformer should survive just fine, although the output voltage might drop a bit, but the drives should handle that,
3. transformers handle overloads quite good, might heat up a bit more, but they do not cut power when overloaded as switching power supplies do.

Quick development update

Over the past few weeks I've mainly been working on two areas that weren't reliable yet: internal machining and automatic thread reliefs.

Fixed internal roughing: The internal roughing cycle was in some cases producing a single, way-too-coarse cut instead of properly staged passes ("not really a cutting strategy"). Found the root cause and fixed it – now it produces even, multi-pass stepping just like external turning does.
Reworked DIN 76 thread reliefs: Previously only a simple rectangular pocket was generated. Now the actual DIN 76 profile is output (30° lead-in, tangential arcs, relief bottom, shoulder radius), using real values from the DIN 76-1 table instead of estimated widths. The relief is now correctly anchored to the end of the thread (not the end of the contour), and it now also works in the middle of a longer contour, not just at the very start or end.
Safer internal approach moves: When feeding into a bore, the tool now always moves axially to the clear retract plane first and only then feeds in radially – no more diagonal rapid moves straight through the bore.
Also fixed a few real LinuxCNC crashes along the way (e.g. tool nose compensation at the inside relief corner, a "Not monotonic" error with G71/G72 when a relief is spliced into the contour).
Important: All of this is currently only on the dev branch, not yet in the stable release. Not everything has been verified with a real dry run on the machine yet, but preview and generated code now look correct for the cases tested so far. As always: feedback, test cases, and criticism are welcome.

Shaft Gauge - a free browser tool to measure STL files (mm)

I built a small, single-file web tool for quickly reading dimensions off an STL mesh, handy when you just need a measurement without opening full CAD (with claude AI).

Drag in an STL and you get:
- Diameter and length (auto shaft-axis detection) plus full bounding-box dimensions
- Point-to-point distance with vertex snapping
- 3-point circle fit to read a bore/round feature diameter (works on tilted planes)
- 2D cross-sections on the XY / XZ / YZ planes with a movable slider
- Volume, triangle count, light/dark theme

No install, no sign-up, and your file never leaves your device - everything runs locally in the browser (binary and ASCII STL). Open source (MIT).

Feedback and feature ideas welcome.

Since you said the link was wrong, feel free to post the correct one and do a bit of promotion for your Carrot Board

and i could see most of my keys turn yellow in the halshow.

Not sure I understand you correctly but it you have the pins in your hal reacting to your pendant keys wouldn't you just need to connect those hal pins to the respective pins of your gui?

Dear meister:

What informations do you need?

I had posted schmatic, pcb plot vlews,and user manual, in the user manual have all information about this board

A little progress.
After installing the transformer, I'm wondering again whether its power rating is sufficient for three 1.5 kW servo motors.
The transformer is rated at 4.7 kVA, 415 V to 220 V, 3-phase.

What do you guys think? Is 4.7 kVA enough for three 1.5 kW servo motors?

 

Why not post the correct links here again? You could also add a bit of information about your Carrot board.

@all: With some projects, people complain when someone builds and sells hardware for them. You don’t need to worry about that here – it’s an open-source project, and I have no financial interest in it; it’s just a hobby. On the contrary, I’m actually really pleased when someone else offers others the chance to get ready-made hardware. I’d be delighted if there were even more of these available – and ideally in a way that means you can order them here in Germany too (AliExpress?!?)

OK, there’s just one thing I do expect: if you end up becoming millionaires because of this, you can treat me to a meal ;P

Best wishes, Olli
