Probe Basic Manual Tool Not Working

Category: QtPyVCP

Glad you got it sorted. The docs are only giving probe basic specific information, the assumption on configuration building is that the main lcnc docs are used to obtain a working config. In that regard the connections for the probe basic UI dialog are what's being connected here in lieu of lcnc stock dialogs. This gives probe basic control of tool change ques. with the limited number of people working on probe basic, typically 2 or fewer at any given time it's too much to cover what's already available in linuxcnc. This is why we express the importance of qualifying a working configuration in axis before beginning the transition to probe basic to eliminate any general linuxcnc configuration problems without the complexity being compounded by the probe basic requirements.

For your situation it's 100% uncharted territory because none of the devs use Ethercat. If you would like to contribute a docs section for Ethercat users it would be greatly appreciated. The sphinx docs source files in the repository are where the doc pages reside and you can write up the specifics needed and format in the .rst format and submit a pull request and I will add them to the main docs page. I'm sure future Ethercat users would be very grateful for some guidance on how to avoid pitfalls the standard config docs can cause.

Let me know if you need assistance getting started.

Probe Basic Manual Tool Not Working

Category: QtPyVCP

Thanks, I was able to figure it out.

I did read the words.  In fact I reread, prior to posting here.   To be honest, all the documentation is light, I would rather follow the docs than be a pia, yet we all are humans and make mistakes.
If you were asking if I removed all the hal_manualtoolchage, yes there is no hal_manualtoolchange in any of my hal files.

The issue is that the other tool-change nets were not defined. So while I followed the words and removed the red, it also implied to add the other nets.  I am using EtherCAT so my machine hal was not built from a pnconfig, etc.

For anyone in the future, these nets need to be in your machine hal.
#  ---manual tool change signals---
net tool-change-request    <= iocontrol.0.tool-change
net tool-change-confirmed  => iocontrol.0.tool-changed
net tool-number            <= iocontrol.0.tool-prep-number

It would be very useful to add the INDEX input to the encoders, if you want to use oriented spindle or the lathe to do threading.

You're missing the main hal file section or at least are not showing it here. Your posting the post gui Hal file above. My image is of the machine.hal or whatever you named your machine. The one from pncconfig or other config builder. Read the words in the docs not just the pictures.. ?

Probe Basic Manual Tool Not Working

Yes, I did follow the directions. Sorry, I should have stated that, but I used step #4. I only posted the section to ensure I did not mess that up.  I feel like I missed something very basic.  I can trigger the modal using showhal and setting 'tool-change-request' pin

The directions don't have the tool-request-loopback net, is that needed?

Here is the entire post UI hal

loadrt time
loadrt not

addf time.0 servo-thread
addf not.0 servo-thread

net prog-running not.0.in <= halui.program.is-idle
net prog-paused halui.program.is-paused => time.0.pause
net cycle-timer time.0.start <= not.0.out
net cycle-seconds qtpyvcp.timerseconds.in <= time.0.seconds
net cycle-minutes qtpyvcp.timerminutes.in <= time.0.minutes
net cycle-hours qtpyvcp.timerhours.in <= time.0.hours
# *** Time items required for Probe Basic to run ***

#  ---manual tool change signals---
net tool-change-request     =>  qtpyvcp_manualtoolchange.change
net tool-change-confirmed   <=  qtpyvcp_manualtoolchange.changed
net tool-number             =>  qtpyvcp_manualtoolchange.number

# *** Probe graphic simulation trigger push probe tip ***
# net probe-in  lcec.0.Z.din.1  qtpyvcp.probe-in.out

# net spindle-speed-fb hy_gt_vfd.speed-fb => qtpyvcp.spindle-encoder-rpm.in

# Status LEDs

net ethercat-0-Z-limit-pos lcec.0.Z.limit-pos => qtpyvcp.led-lcec-0-Z-limit-pos.on

net ethercat-0-Z-din-2 lcec.0.Z.din.2 => qtpyvcp.led-lcec-0-Z-din-2.on
# TODO how to we get the current stage of the HW pin, not the state of the hal pin

net mist-on => qtpyvcp.led-lcec-0-Z-dout-1.on

home build cnc cutting fabric machine

Category: Plasma & Laser

hello all 
I'm planning to build a fabric laser cutting machine
but as I have not enough space (and money) for buying a real machine and as I need to cut very long part, I've come up with an idea 
I will keep fabric on 2 rollers (1.5 m long) passing from one side on another from a cutting line (Y axis) with a moving laser diode head (X axis) 
if it was so simple I would use a cheap 3D printer / cn machin controler but whatbrings me here is that I need a closed loop position controller 
idea is that roller will be motorised by 2 motors ( left and right ) and will only working by pulling on fabric ( meaning that 2 motors will work in +Y and 2 in -Y) but I can't rely only on steps on motor to move accurately the fabric as depending on roller fabric diameter changing the distance of fabric moving on cutting line 
File Attachment:

on the other hand fabric can also moves on X axis when rolling and unrolling and objective is to use differential of both right and left motors to correct position 
in my idea the close loop in postion control can be supporte by an optical mouse sensor that can track X and Y moves and I can put 2 on each side right and left 
my question is: is linux cnc can be configured to adapt of this strange machine ?

Delete the red potion and make sure the lines above and below it are there still for the manual tool change.

need some lines in your main hal file also, check the docs it spells it out very clearly in the machine config setup docs. step 5.

New "BIG" Probe Basic Release for Develop Branch Incoming!

Category: QtPyVCP

Hello All!

We are preparing to merge a BIG Probe basic update. it will require some config setting updates and some new folders be added.  I have added a new "Update Release Notes" section to the docs page which should be very helpful going forward for when we have updates release.  please feel free to have a look and give feedback!

Probe Basic Manual Tool Not Working

Category: QtPyVCP

My manual tool changing does the Probe Basic. 
If in MDI I use "T2 M6 G43" , the line stays active with the play icon, but never ends.  The same issue in NC files.

Nothing happens, no pop-up, etc

Here is probe_basic_postgui.hal
#  ---manual tool change signals---
net tool-change-request     =>  qtpyvcp_manualtoolchange.change
net tool-change-confirmed   <=  qtpyvcp_manualtoolchange.changed
net tool-number             =>  qtpyvcp_manualtoolchange.number

Retrofit Hyundai lathe?

Payed much more (3280 Euro + Mesa boards) for this but it was working...till mice had a run at it in my shop! :)
Retrofitted and working with LinuxCNC (see videos on that link), so yes it is worth retrofitting it.
Difficulty is high for sure, so see if you can get the schematics for it, that will save a lot of time and headache.

New HAL Components - Best Practice was created by kubes

New HAL Components - Best Practice

Category: HAL

I am new to LinuxCNC, but I play a software engineer in life.  I have identified a few areas where new or updated (and refactored) components could be beneficial.  What is the current best practice to build HAL components?  I would assume halcompile, but more specifically, .comp files or just long-hand .c?  The components that I am currently thinking about are in the user-space.   The first one I want to tackle is an updated/new hy_gt vfd component.  I am running 2.9, so backward compatibility is not a personal concern for me, but maybe people don't update?

Any feedback would be appreciated.
Thanks
