After using two model of pi (4B and 5) I still get disappointing results. Even at slow printing speeds around 25mm/s there is layer shifting and unreliable motion throughout the operation. I believe now that pi + GPIO struggles to keep up with the pulse generation. Even though I am doing indexed printing (orienting the bed only between sections of printing, so no full 5 axis kinematics) My application is a 5 axis (3 + 2 tilting bed) 3d printer.

I think this was mentioned in the instructions that the PREEMT linux kernel was compatible only, but not recommended as 'industry standard'. Since I cant afford a Mesa FPGA card I am going for klipper on an Octopus board and try my best there. Thanks everyone for being super helpful. And if anyone is interested my 5 axis slicer is on Github, it is A Blender addon that works if you also have the Cura engine up and running. You would be able to slice more complicated models with overhang and printing it by rotating the bed (if you do have this kind of setup).

I like it.
Thanks

Looks like this

Is there a way to launch it in a smaller window (even if the text results small) so I can drag it somewhere in the screen while debugging?

Hello everyone and very glad to be a part of the community! This is my first post

I am super new to the linuxcnc and I have actually been reading the forum for the last couple of months trying to get started by myself and trying not to bother everyone with the questions that could be found in the documentation and/or previous posts. However it seems that now I have hit the limit and it takes toooo much time to get unstuck. I would really appreciate some push in the right direction

Anyways, I am trying to build quite a complex machine that has a single motor to control something like a winch and pull some things up and down. I got myself a Delta ASDA-A2-E inverter running a 1.5kW motor and I managed to get it moving using the Ethercat driver and axis GUI. The control is running on the Raspberry Pi 4B and I managed to get the linux cnc installed and running and to spin the motor in a position control mode, even though, later on I will need to use the torque control. But all of this was mainly the learning curve to actually get started

So what I would like to do is a simple GUI (probably from scratch) that would allow me to set the needed torque. Torque control will be quite complex, so I will need a place to write my own controls (I would prefer c/c++, but probably I can survive also with python). There should be also other functions for safety, data collection, etc, but this I can add along the way. Can you guys please help me set the simplest Hello World project where I would be able to get started? I would really appreciate any help.

Up until now I have been trying on Linux raspberrypi 6.1.54-rt15 but I am willing to start from scratch if there is a better option.

Thanks in advance!

awesome

sorry i didn't check the notify me box so only just stumbled across this.

just getting a bit stuck working out how to download it and install.

ideally a guide would be great. or something. I can go back through the thread and try to see what i missed but any up to date info would be great

i always seem to get caught out in the little details. like i have the wrong repo or just missing a command

but i have done many retrofits so not completely useless:)

but i think i might need a tiny bit of hand holding on this one.

cheers

This is a post that clarified a lot of stuff about this topic

www.forum.linuxcnc.org/12-milling/42241-...yder-cnc-mill-router

BTW I had success sending a tool number on the main window of PB, it runs the subroutine m6_tool_call_main_panel.ngc that you should edit whith your atc position.
Don't know if this is the way to do it, something tells me it's not

Now, I am planning a CNC welding setup.

In my application, touch sensing with Mig-wire is a must. Now, I tested the continuity between torch tip and earth clamp, it is already a closed circuit inside the welding machine. Then how do touch sensing work? 

Looking for help/ideas.

Anyone already using such setup??

11 hours you've done well!....

What is the actual command are you using for ping

Mmm, pizza fixes everything.

For the curious who might want to use lenovo tiny pcs:
- The pc needed a bios update to disable CSM mode. (legacy compatibility) and turn secure boot off.
- The bios needed to go on a bootable DOS stick, which was not super clear in the instructions and its been AGES since that was a thing haha so I just forgot.
- Once I got the bios on I still needed to reinstall linuxcnc cause I guess the boot record was still messed up.

After all that, its fine. Now to do the work I intended to do like 11 hours ago!

I need a nap.

@hellvetica Looks like I have same or very similar issue. What exactly was wrong with wiring in your case?

So with the official image if I install Network Manager then it fails at between 50k and 70k pings... However if I leave the network bone stock like the image (so using commandline and config files to manage) then 100000 pings at 1ms/ping and a response time of 0.105ms so yah... I think it was Network Manager that was the problem.
