I'm writing an article on #LinuxCNC and, I dunno why it appeals to me, but the fact the machine controller setup (a Pi5 in this case) can take screenshots and upload em to shared drive etc feels ace!

@la @MisterMaker
I do have a leftover Hub75 card that can also be utilized for #linuxcnc instead of the MESA card. You can have if it you like.It also features the nice flex-PCBs from @marble, so card has inputs.
Not sure how much pain the software is though. Have never tried it myself.

Finally got around to mounting my relayboard for the cnc. I spend quite some time in FreeCAD to make the threaded clamps.
Unfortunately the reason for getting into the cabinet was that the modbus/rs485 connection to the vfd was dead. I ordered a new usb-rs485 thing after rewiring and testing.

Wodden boxes I made for xmas presents.
Made with my #cncwoodoruter using #linuxcnc cad/cam was with vectric vcarve.
It was quite a challenge doing two sided machining. I ended up making a fixture, to machine the outside.
Topsides were a 2.5D relief motive. Bottom was engraved with "made by pedersen, xmas 2025, for y"
Walnut wood finished with furniture wax made from beeswax and linseed oil.

This weekend project was adding relays to my #cncwoodoruter with #linuxcnc this proved to be a nice learning experience with #freecad and the linuxcnc hal system.
FreeCAD to model a relay board mount. Which is now on #printables for #3dprinting https://www.printables.com/model/1552269-8-channel-relay-mount
I did go a bit overboard with cable channels and snapmounting - I still need to do a bit more for a wall mount and perhaps a cover. -

Today's CNC job at @cccac was this motor mounting plate for our CNC mill.
@la and me did the drawing in #FreeCAD and millied it out of a scrap piece on the #LINUXCNC machine.The only complaint is that it looks quite boring.
Since the belt is still missing, we cannot test fit it yet. So fingers crossed that all measurements were correct.

I'm wondering whether it's possible to have a device running #linuxcnc which can take an extra input which is continuously added to say the X axis to cause a variable offset in the X position?
Imagine a device which repeatedly traces a pattern on a moving conveyor belt. This is the sort of thing usually done with a PLC but there seems no reason why LinuxCNC couldn't do it.
I wonder though whether #grbl might be a better option?
Anyone understand what I'm trying to ask and have any ideas?

Sodding Hell, it seems that turning a path in an SVG file into a series of lines and arcs for CNC GCODE is no longer a possible thing in the FLOSS world using distribution packages or even pip.
You'd have thought #LinuxCNC would have it sussed, but that's held together with manual patches and scripts.

With the new #PREEMPT_RT #linux kernel hitting mainline I wrote an article on the importance of kernel parameter tuning to reduce latency and jitter for #LinuxCNC

Curiously, some of the best docs on #Linux PCIe parallel port cards is the #LinuxCNC wiki;
This probably explains why my MosCHIP PCIe doesn't want to do EPP (although it's data sheet looks believable for EPP); I've got another machine which has a CH382 and even it's data sheet doesn't make sense about how it's supposed EPP and ECP modes are supposed to work.

Next step for the #LinuxCNC mini-mill is a touchscreen. So I ordered one for which the seller explicitly said it supported the raspberry pi, including how to hook up touch.
Not only does it not show up on touch, it no way no how shows up in
lsusboutput. I guess there is a chance the seller comes through with a fix, but probably it's going to be a return.I'm looking for a reasonably inexpensive 14-15" touchscreen monitor with a reasonable number of pixels (the 1920x1200 on the monitor I bought looked nice) and VESA mounting (75mm or 100mm pattern, I don't care), that is known to work with a raspberry pi. Anyone with relevant experience have one they would recommend?
I really don't want to have to have a mouse wandering around the mill table. ☺
