Good Evening,

I'm relatively new to LinuxCNC having come from Mach 3 on mills previously.  Having found mach3 limited for lathes I have moved over to LinuxCNC.  I have been/have converted an old Boxford 240 TCL to run on new steppers, and LinuxCNC running on a Pi5 connected to an ec300 running the remora firmware.

Everything in general is working fine, except the spindle encoder.  Annoyingly, it is not a quadrature encoder.  It is a 100ppr slotted disk with an additional index pulse.  Currently, this is feeding directly into the Pi5, which is reading the 100ppr but missing the index.

So, my plan is to move the encoder and index over to the ec300.  While i understand that the ec300 has a dedicated index input, I am unsure on using an encoder with remora.  I've read the docs, and have run through this thread but my head is spinning trying to get things straight. 

Does the EC300 have the ability for a hardware encoder?  if not, software would work too, I'm just not sure how to set up the encoder component as I do not have a B phase.

On the hardware side, I'm going to have to work out some electronics as the encoder as it stands is running on 3.3v with schmitt triggers for conditioning.  So I will have to come up with something to level shift this to 24v.

Any help that could be given on the remora side of things would be greatly appreciated.
 

9660. The DVD drive fails BIOS diagnostics. Spindle error. I am ordering a replacement drive. In the meantime, I used a USB DVD drive. The 2.9.2 disk would not boot. But an ancient disk from Sherline called EMC2 did boot and install from that USB DVD drive. This is so ancient that Update Manager does not work. I put 2.9.4 on the DVD. While trying to install, it complained about unmounting media failing. I suspect 2.9.4 ISO lacks the smarts to handle a USB DVD drive. I have successfully installed 2.7.14 before so that is next.

Hello everyone

After seeing your video (looks really great by the way), I wanted to check out MonoKrom as well. However, following the instructions on the QtPyVCP repo, I fail at the step of installing MonoKrom itself. The apt source seems not be available anymore.

www.qtpyvcp.com/install/apt_install.html

$ sudo apt install python3-monokrom

Greetings Sandro

Progress. I cut the end frames down from the old machine so chips don't build up at the ends of the rails. this lets me reduce the safety margins and I get about 310mm y travel now. Also made a new top plate for the Z which increases clearance 10mm, and ups the travel to 112mm. Much smaller than the new version, but we don't have that yet sooo

Since no one stepped in, i do recall that discussion but not the end result.
I did refrain from posting there as i still vigorously maintain that capacitive sensing has no business near a plasma machine, as proven by a quick glance at new industrial machines.
I did remove plenty of fully functioning capacitive sensors from industrial plasma machines and replaced with float switch. It never fails.

What model of OptiPlex ?

Working on fixing the broken install.
I wasn't able to do that previously because I was not the root user. Some google sorted me out there.

I'm pleased to report that I have successfully installed Probe Basic!
This is a huge win for me because Linux and LinuxCNC have been my nemesis since I first tried using it in 2021 when I built my PrintNC router. I gave up because I simply did not know what I was doing. Four years on, and three CNC build later I have a modicum of a clue now.
Each of the posts in the thread represent more learning for me and your help has well, helped me get to where I wanted to be.
Thanks all!
 

just for clarification, in Linux with any program when installing in terminal, if dependencies are missing they will cause an installation error, you need to read the terminal after each command to verify if the installation was successful or if there was a complication that needs to be addressed, it will give you any clues as to what is wrong very clearly.  so in your example, there are missing dependencies as shown in the terminal boxed in red outline.  the solution is to immediately run after that installation command the following command shows in red text.  that should resolve and then the previous installation will continue automatically and complete.  now if you ignored any of the dependency errors in previous installation lines for linuxcnc, hiyapyco, qtpyvcp, you would need to go back and rerun those in the correct order from the docs and running the dependency fix directly after each.  the order is important because each item is a dependency of the previously installed component.

linuxcnc > hiyapyco > qtpyvcp > probe-basic

 


 

Just machine control. I'll try the apt install.

No that references Mesa Modbus and several userland modbus interfaces
that use kernel serial port/USB serial port drivers.

When you see errors like the missing dependency shown in the top line of your screen shot, those are what stop the installation from proceeding. While installing, if you encounter those, you can auto install them by running:

sudo apt --fix-broken install

which will gather all of the missing dependencies on your system and install them.

added location, had put on subject but added it to top of list now

Are you trying to install a dev work station or just a machine control? If a machine control, use the apt installation.

Hello,
this is my almost working postgui. This works is Input-04 is a switch. But i want to use a push button. What can i do?

#[Startknopf]
loadrt or2
addf or2.0 servo-thread

loadrt not #mit diesem Befehl wird ein not.in/out in die Pins geladen
addf not.0 servo-thread
net Start.not.out => not.0.out # hier wird not.0.out startbar gemacht

net Start.ext.an <= gladevcp.Start => or2.0.in0
net Start.ext.an1 <= hm2_7i76e.0.7i76.0.0.input-04 => or2.0.in1
net Start.or <= or2.0.out => hm2_7i76e.0.7i76.0.0.output-05 => halui.machine.on => not.0.in # Eingang not.0.in wird über den or2.0.out gesetzt

net Start.not.out => not.0.out => hm2_7i76e.0.7i76.0.0.output-06 => halui.machine.off
net MachineLED <= halui.machine.is-on => gladevcp.led_Startstopp

Hey, Ive been meaning to work on this and Dmitry's up camera, but before that I needed to build/install/configure my hardware with c axis before I started on this.

Nothing against qt/glade, but for simplicity I am trying to do everything in an Axis tab with tk/tcl/tkinter, and probably using usercommand file so that is my challenge.

The usercommand file Ive included is your initial file, but with a camera tab created in axis. I am using this as a starting point.

first hurdle : conflicting mainloops between axis and opencv

here is solutions, but Im trying to understand them first (I struggle with OOP)

Hello,  this is a bit off topic, but does the axis C component work perfectly? Thank you for your feedback
