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 probe-in  <=  qtpyvcp.probe-led.on

# *** Set line below for actual spindle readout from your hal file ***
# net spindle-rpm-filtered scale_to_rpm.out  =>  qtpyvcp.spindle-encoder-rpm.in
# net spindle-speed-fb hy_gt_vfd.speed-fb => qtpyvcp.spindle-encoder-rpm.in

# Status LEDs
net ethercat-link lcec.link-up => qtpyvcp.led-lcec-link-up.on

net ethercat-0-Z-limit-pos lcec.0.Z.limit-pos => qtpyvcp.led-lcec-0-Z-limit-pos.on
net ethercat-0-Z-limit-neg lcec.0.Z.limit-neg => qtpyvcp.led-lcec-0-Z-limit-neg.on
net ethercat-0-Z-din-1 lcec.0.Z.din.1 => qtpyvcp.led-lcec-0-Z-din-1.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 ?
