Hi Rob, how's going over there? You still making model car parts?

Pop in the IRC. Note: #linuxcnc has moved to Libera.Chat and #flex-dev is my channel

4 X max31855 or max6675 will read the thermocouples of heaters
and linuxcnc will do the pid driving solid state replays for temperature regulation. I plan to use an sbc like rpi5 or opi5 with touch screen.
Now for plastic dosing the are mechanical regulators with switches
that the plan is to replace with linear encoders or linear sensors measuring distance and limit switches replaced by photoelectronic or induction sensors.
An sbc like rpi5 or opi5 will be enough using GPIO headers
and 24v breakout board for driving electro valves ?

Also am looking if it is possible to remove all hydraulic system
and convert it to pure electric machine with servomotors
because mold locking is done with toggle mechanism.

Sliding Head Lathe for sale - maybe grate devlopment tool for linuxcnc ? UK

Category: User Exchange

Location UK, Cambridgeshire

For sale i have a used Citizen L16 it has 20mm upgrade guide bush for it also
,love to see it go to someone who can maybe retro to linuxcnc and get some devloment progress on dual spindle programing and multi spindle/dual path programming

 reason for sale its not being used  as i upgraded to a M20 Citizen slider in its place and no space to have both.
price - £1500
buyer picks up i can load to buyers transport with pre aranagment , or send your own machine mover as it is a pickup and go no skating needed.

the origianl control does dual path program, $1 for main, $2 for sub,$3 is for setup pramiters have made many parts of all types on it, in materials from Steels, Stainless, Titanium etc never a problem for this machine.holds grate tollerance, all axis work fine, all spindle work grate axis

programable , Z1,X1,Y1 , Z2,X2Spindles 3, Main (+indexing),
Sub & Power toolingBar feeder ready interface (was ran on Imeca magazine)
can only work on simple single bar type barfeeders also.

can run ground or non ground bar on it
Main & Sub spindle uses F25 collet type, very common to find - sorry i dont have any i can include as our new machine uses this type also. 

has power tooling on the main slide,
i have the slide unit that runs 1x power tooling , also slide unit that takes 2x power tooling. these are easy to change over,
and in the control you tell the machine which unit is in use and it will adjusts all offsets etc for the slide units. 

machine has dual path programing so main and sub slides can do there own things, or work together. very powerfull machine when used to true protentional.i have the manual for the machine, paper copy only includs drawings, programing and using of the machine.

Guide bush type depends on guide bush module in use (max 16 OD unit type B238 (61.002), or max 20mm OD unit type B261 (22.001))
i have a driven and static guide bush unit for the B238 types - included in price (photos now added of these)

i have a handfull of B238 Collets i will include in the sale for free , alot are odd sizes from running plastic bar & aluminium.sorry no main orCollets included now added in photosall collets are round,
Sizes are: 2x10mm, 7mm, 3/8",9/32",8.5mm,9/16", 5/8", 6mm, 13.5mm, 1/4",16.6mm,12.85mm,16mm,2x8mm  

has indexing on the main spindle only, this is every 15deg with a lock peg to hold position, sorry no true C axis 

power tooling holders take standard ER16 Collets. 

have upgraded the old inverters to newer Mitsubishi units for the main and sub spindle upgrades aprox 3 years ago, also upgraded the old DC power tooling motor to AC servo motor so more speed & Torque than standard.
had a new encoder on Z2 motor about year ago. 
also changed the old CRT to LCD screen

the machine is fully barfeed ready with a socket for the interfacing of a magazine type barfeeder,
there is no bar feed included as we used this on our new machine. but i do have a LNS magazine barfeeder that i belive could be made to work/talk to this machine that i can offer  to the buyer with machine for £500 

machine is underpower but has been in storage for awhile now and has lost its pramiters, i do have these but it requires reloading due to it being in storage batterys are flat in it ,
machine is sold as seen but was fully working and making parts untill our new machine arrived.

no tool holders included sorry. 

machine weight Aprox 1Tone
machine requires 3 phase 400v supply to transformer which is included for the machine 400 to 200v 3phase 

any questions please contact us,

if you wish to view the machine please contact me
.questions please post here it is listed else where also.

It was the probe height setting. Increasing the probe height setting a lot made it work with one touch. 

Looks ok now.

Is there a new Linuxcnc release in the wings ?

Category: General LinuxCNC Questions

Agreed; so much good code goes to waste; at least it's open source!

Dead proprietary programs just go to waste.

But why is there a double sense always? 
It should be enough with one, the first contact.
The plots are from a web csv plot tool, output from the sampler component to record longer sequences.
 

The following settings have been used.

EL8 - Rehoming axis goes max speed ignores machine and driver limits

Category: EtherCAT

Hi Shemj
I am currently having the same issue as you when I press ref (X/Y/Z) in probe basic the machine moves to its 0 position on that axis uncontrollability ignoring the maximum velocity.

Please let me know if you have found a way to home to machine and retain the encoder values when the machine is powered off ?
cheers will

That should not be a distro issue, but a config issue, so do start a new topic and upload both configs so we can have a look.

Proposal RPi Linuxcnc Image Based on Raspi OS All welcome/encoraged to comment

Category: Installing LinuxCNC

I'm happy to be helpful to the community even if it is just planting ideas into smart people's minds :)

That is quite a habit to have, so use it as much as possible.

Proposal RPi Linuxcnc Image Based on Raspi OS All welcome/encoraged to comment

Category: Installing LinuxCNC

Saw that, but was too lazy to setup the spare RPi. In fact that was what led me to pi-gen. Tho I haven't completely ruled it out.
Tho I do seem to like with pi-gen you can stop the process at certain stages.
Luckily or maybe not so I'm in a position where time is something I have plenty of. Also a couple of PC's I can use to build different configs. Sadly only one spare RPi400 and one spare RPi5, with the RPi5 being part of a very generous gift on Father's Day from my son.

first of all, thanks for the kind(-ish, lol) words, I'm happy to be helpful to the community even if it is just planting ideas into smart people's minds :)

have you seen github.com/raspberrypi/rpi-image-gen? to me it looks like a better fit for the purpose - all we need is to install some packages and configure some things, right? building the entire distro from scratch seems excessive.

Axis configuration not fully working on 2.9.6

Category: AXIS

The buildbot doesn't seem to be working properly at the moment.

I have build a test .deb manually instead.

www.linuxcnc.org/temp/linuxcnc-uspace_2.9.7pre_amd64.deb

You should be able to download the file and install with
sudo apt-get install ./http://www.linuxcnc.org/temp/linuxcnc-uspace_2.9.7pre_amd64.deb

Note that this will overwrite your current linuxcnc installation (or will install linuxcnc if it is not installed on the machine). It will not alter the Linux OS and your current machine configurations should be unaffected.

Raspberry PI4/5 I2C support for non realtime IO/ADC/LCD

Category: General LinuxCNC Questions

Hi,
i wrote a hal component in python to control some I2C devices

*  pcf8574 : Digital IO's
#  ads1115 : Analog input
#  lm75  : temperature sensor
#  hd44780 : LCD display

It is actually part of the RIO project, but can also run independently.
Maybe someone can use it.
It's also no problem to install additional devices. Just let me know what you need; I have almost everything here :)


Cheers Olli
