I noticed in the latest RotarySMP video that he is using FreeCAD.

So do i, for several years, i did whole machine design in FreeCAD and 3D printed the results

Hi Pcw,

Can you try once more with Mesa?

In the repository :
git pull
cd cmake
./build_cmake

Added pins to monitor at runtime:
tpmod.hal_component_max_cycle_time_ns
tpmod.hal_component_max_cycle_time_scurve_ns

Param to start with, also influences max acc :
tpmod.hal_max_jerk = 5

Then the above pins must stay below ~50000 nanosec at runtime.
Everything above 1000000 ns is bad.

We have now 3 configs wich run scurve. 1 is in Slowakia and runs like a rocket on delta servo's.
My ethercat steppers run, but not optimal as my desktop pc has bad latency. Base thread & ethercat apptime = 80000
Another machine is in Italy and had bad .hal config wich broke the scurve at runtime. Now that is fixed, it run's.

G-code file loading at G53 instead of G54

Category: Qtvcp

Hello, 

I'm not sure if this is the right sub-forum to put this, but it seems close.When I load a G-code file onto my mill running QtDragonHD, the code is initializing at the G53 machine origin (top front left corner of the work envelope), rather than G54 as called out in the code (work offset zero in the middle of the work envelope). Please see the attached image (sorry it's not a screenshot, I don't currently have an easy way to pull screenshots off the mill computer) and G-code. 

Does anyone know what I might be doing wrong with my configuration or code to have caused this?

Linuxcnc & the Raspberry Pi (4 & 5) Official Images Only!!!

Category: Installing LinuxCNC

There was a user having an issue with gmoccapy locking up, but this issue was related to zram, which was discussed earlier in this thread.
I've had my RPi 5 sitting there with Axis open connected to a "cobbled together" 7i92 and after a week and a half have only dropped one packet.
When I get a chance I'll look into the ethernet setup. For some basic advice, do not have a gateway nor DNS server entry for the NIC that the mesa card is connected to, it generates unwanted traffic on that interface.
TBH I'm not up on the meaning of the LEDs on the card you are using.
It maybe worth checking the manual and searching the forum for that answer.

Ganty sawmill was created by vre

Ganty sawmill

Category: Advanced Configuration

I want to retrofit an old 5 axis gantry sawmill and achieve functionality like this machine
www.hualongm.com/stone-processing-machin...italian-pegasus.html
www.esautomotion.com/marble-working/
What user interface can be be a good starting point ? qtdragon_hd ?
Non trivial features are cutting with disk and spindle finishing cuts in the corners or small radius cuts or waterjet
and optical recognition of slabs with camera (opencv)
Any suggestions ?

Change Tool Offsets after editing the Tool Table

Category: Gmoccapy

If you edit the tool table, save the changes, re-load the tool table in the GUI and then issue a G43 in MDI then the tool diameter really should change.

Maybe it's the "reload tool table" step that is missing?

Is the Z limit switch also a home switch?

halshow (in Axis menu - Machine - Show Hal Configuration) will let you explore whether joint.2.*-lim-sw-in is not working properly.

Zero Pierce delay After pierce Only

I was not awere of this working mode, it can be useful because you can use  sheetcam drawings or generate in QTplasmaC.
but still need change pierce delay in tool.
