For the Z-180 after homing:

My startup procedure is: Starting the configuration and homing. After that the Z Axis is at -180. See screenshot attached.

For the different tool change position:

Toolchange from no tool to lathe tool:

X-Axis-Position: 250mm
X-Joint-Position: 623.2051mm

Toolchange No. 2 from lathe tool to endmill:

X-Axis-Position: 330mm
X-Joint-Position: 873.2051mm

The Y-Joint-Position is the same.

Spindle orient:
"Because this value changes instantly it would likely cause a following error in the b-axis drive " that was the missing bit of information.



 

Either pncconf or MesaCT can make working configurations for a 7I96S
(and MesaCT can make working configurations for the 7I95T AFAIK)


What actual issue do you have?

Measure the input voltage at the VFD it's probably at 10v constant ?
​​​​​​ Yes you can also hook up outputs for  FWD and REV.

OK, This is a Merckweir MK300 VFD that was installed from the factory. As par for the course with this machine, the unit is an old out of production version. All this that I am trying to do now is to salvage the purchase of this mill after taking a giga hose job and losing over $3k.

To answer your questions in order -
1. Nothing happens when I try to adjust the speed. Whether I issue an M3 S100 or M3 S15000, the speed is the same. VFD panel reports 3500 rpm, or at least I think it's RPM, anyway, no change.

2. Yes, VFD

3 The input is suppose to be 0-10v and if the translator on my phone is correct that is connected to the AI1 (0-10v analog signal input) on VFD

3. As far as I can tell.... There are only 3 wires, COM, AI1 for the 0-10v analog and X1 that connects to spindle out1 (spindle-cw)

I had posted some photos of the 8 spindle machine and the configuration file here, if is at all helpful. You can see there how I handled slaving the extra joints to the Z axis.

Axis is a great GUI and very stable, the problem with Axis is it's super complicated to try and change the behaviour. Once you start to need a custom GUI this is where Flex GUI shines.

Hello Corbett

Thank you very much!

I'll try it here

Do you need the Realtek card?

Physically remove all unneeded hardware.

Try disabling all power-saving features you can.

./remove_all

What does it do when you try adjust the speed? Is it a VFD you are using? What is the speed input to the vfd pwm or 0-10v analog. Have you the VFD wired correctly ?

I'm a n00b, straight from UGS, so I don't know if that will be an issue. I anticipate using the pendant during setup, so being on the "Manual Control" window might not be a problem.

What's a solution to the focus problem?

Yes PCW, is the same Realtek with dkms driver for fix latency.
Maybe I'm asking the wrong question: is it really necessary to do the test with YouTube?

When you get an error, what does:

halcmd show param *.tmax

(typed in a terminal)

show?



 

OK, I figured out a way to select from the GUI list of jog increments using a single keystroke.

There's more than meets the eye. You've got to pull in some GUI elements that are only apparent if you read through axis.py. It's not good enough to set the increment because the GUI will re-set it based on the dropdown.

import linuxcnc
import tkinter
import hal

def set_jog_inc_rc( event, index ):
global comp, jogincr_index_last

root_window.call( widgets.jogincr._w, "select", index )
jogincr = widgets.jogincr.get()
print( f"setting jog increment to {jogincr} inch " )
comp = float( jogincr.translate(str.maketrans("", "", string.ascii_letters)) ) # remove "in"


root_window.bind( "<e>", lambda event: set_jog_inc_rc( event, 5 ) )
root_window.bind( "<f>", lambda event: set_jog_inc_rc( event, 3 ) )
root_window.bind( "<g>", lambda event: set_jog_inc_rc( event, 1 ) )

True.

Also, make sure the function keys don't invoke some system function.

Pressing [R] should run program, but does nothing for me.

The only shortcuts that work for me are:

[Home] -> Home current axis.
[End] -> Touch-off current axis.
[Up Arrow], [Down Arrow] -> Jog and select Y-axis.

Try deleting [spindle0]

setp scale-rpm.gain .02
put that in instead
 

 

At least that gets me to the next error - ./remora-ec500.hal:127: Pin 'remora.output.02' was already linked to signal 'spindle-cw'

line 127 is - net mist    remora.output.02     => iocontrol.0.coolant-mist

Edit: I figured out that the pin for the spindle was wrong, it should of been .00 not .02. Now I have the spindle turning on. First time I have seen the spindle run sense the day the machine shipped. No speed control and I am unsure how to fix that, but at least I am making progress. At this rate I might even see the mill actually working before fall.
