Is there any other cam software for tangential knife except sheetcam ?

Ok let me compare that with my machine as I am using also two parallel ports.
I will get back to you next week when I have been been at my workshop.

you marked out one too many tool change lines in the hal.

 

Okay, I think I didn't explain myself in my first post. When I said "install," I meant exactly that: using the SIM files on a machine already configured with Axis.

The problem I was having was with the PostGui file, and I already solved it. I had to comment out one more line.

Now it starts up perfectly, but I can't change tools; the Probe Basic tool changer window doesn't appear.
If I use the Axis tool changer window, it switches perfectly.

I'm running linuxcnc 2.9.4 (which I downloaded from Debian 12 Bookworm PREEMPT-RT ISO ) in VirtualBox in order to try out the various UIs etc. The actual CNC is being driven from a Raspberry Pi. I'm currently running gmoccapy but I'd like to try out the QtDragon UI.

I found some instructions that said I needed to install linuxcnc-uspace-qtvcp but it's not in the debian repo and I didn't want to start adding random sources without knowing what I'm doing. There are also references to modifying .ini files but there are a lot under sim.gmoccapy so it's not clear which one to modify, and in any case, I thought using QtDragon meant not using gmoccapy.

@Endian,

When you run the scurve in linux. The joint.[x].... hal outputs already show you position, velocity, acceleration that is
usable for your servo drive. The halscope shows a acceleration curve that is indeed not constant.

@Endian,This is only downloading the clothoid3d source :
user@debian:~$ git clone codeberg.org/skynet/clothoid_3d.git


Check the readme install file, follow the steps :
install readme file

First step :
git clone --recurse-submodules codeberg.org/skynet/linuxcnc_scurve_compact
Install all:
/cmake/./patch
/cmake/./installer

Or if you want to install it on a linuxcnc clone you already have running:
1. copy cmake dir to your local clone.
/cmake/./patch -> or patch files manually : patch manual
recompile your linuxcnc clone
/cmake/./build_cmake

Thanks I tried both of these suggested configs. 

Still no output even when it is set as the only Parallel port for Linuxcnc.  The config itself worked because my motors no longer lock up when enabled as they are still connected to the 0x378 port.  Got no voltage changes on the 0xe800 breakout board even when it was configured as the only port in linuxcnc.

When both ports are specified port0 works but port1 still no output. 

I have taken some better photos of the lspci -vv and /proc/ioports plus a photo of the hal file so you can make sure I am not doing something dumb(this is likely). Sorry has to be photo as machine is not networked and usb ports are hard access currently. 

Starting to think maybe its the card.  I have another card but is is not working in linux. it is a sun1888 card it list in lspci but the drivers do not get assigned to it.  If there is an easy fix to getting this going it might be a good way to test.  (I'm a linux noob but willing to get into the weeds with good instructions) 

Thanks.

Hi,

Ok. We will rename it to : grotius-tp.so

@Endian,
It's still unclear to me what you exactly need.

1. A linuxcnc single axis component that generates a scurve motion, given a target position, maxvel, maxacc, maxjerk.
2. A multi axis pid for linuxcnc that generates motion given target position, maxvel, maxacc, maxjerk.
3. Something else.

Making a pid from a scurve is possible. I am a bit concerned about the following error, but we will see how it works out.

Yesterday, i got messaged by 2 people who have installing problems to enable ethercat & scurve on their linuxcnc iso installation.
Most off the users don't have the skills to install a rip installation, etc. So they have in fact a problem running our software.
It will take them hours & hours to get some install results.

To resolve this, i think i will make a .iso distribution today.
 
 

I need a calculated acceleration command beside of calculated velocity command which I will send to the servo driver ... But acceleration is non constant value in the time I think and therefore I think I need some spline element which will calculate them?
