Hello,

In my view, not necessarily the best idea.
For my part, I felt very useful and pleasant to comment.
It works in other places too.
And I also see no problem that everything that comes after a double cross is simply a comment if it is in the same line. The possibility of creating extra comments lines remains.
The only thing I can think of is that I recently edited the INI and because the comments could have inserted without switching on the milling machine, I can't think of anything else.

What I really miss is an understandable change overview between really every single versions or the place where I find something.

This has done the problem.
Sorry for the sometimes unhappy choice of Google translator, my modest English is even worse.

All the best and best regards, Frank

Sorry to post on a old topic but I wanted to see if this functionality was in qtplasmac in the 2.9.4 install or if you need to be running from the 2.10 master?  Also, has anyone done moving piercing in Fusion360 CAM?

Forget the pots, you can do without them, might need adding a home switch.
And also open the possibility of working with roll's of material, meaning not being limited to a certain length.

Would a compartor with some sort of reference changer circuit that changes triggering voltage based on motor dir work?

When motor dir is positive, it sends a positive limit signal when it spin too far.

When motor DIR is negative, it sends a HOME signal when the axis reaches the HOME location.

(comparator + NAND?)

Will post schematic.

Do the motors have tachometers connected to the drives?
(these are needed for velocity mode)

 

99.9% of people at my school would not be able to calculate that.

(I can tho)

I'm trying to convert my cheap 3040 router with an LPT card to connect to LinuxCNC using a Mesa 7i92TH
Current LPT pinout is :

1 VFD spindle on (CW) , using a small relay
2 X step
3 X dir
4 Y step
5 Y dir
6 Z step
7 Z dir
11 X home in
12 Y home in
13 Z home in
15 probe in
17 VFD spindle PWM (0-2000Hz)

If I read the documentation ( 7i92tman.pdf ) correct the PROB_RFX2D would match it almost perfect , but that file is not in the ti92t.zip from the Mesa website. Which firmware am I best off to use ?

Hello got everything up and running the machine will home. I keep getting the same error and I’m not able to run a program. I am not skilled at writing G code, but hopefully this is a quick fix. Any assistance is greatly appreciated 

In line 39 of the referenced G-code file it looks ike there is a command to call a subroutine. That hasn't been found in the current file, so it is looking for it ina separate file of the same name. 

At a guess (and this is a complete guess) you may be running the cooper_groove_master_2B.ngc  file from a backup location ("Old to Hold") and the referenced subroutine file may not exist in that location. 

Have a look around line 39 (might not be _exactly_ line 39 for a reference to <135> and see what it is looking for, and if that exists elsewhere. 
 

Does the "G54 Work" change to G55 if you are in G55? (I am not familiar with probe basic)

Can you elaborate?
What triggers the motor to home?

i have struggled to find out what "mode" my drivers run in. as far as i can tell there is no option to choose between the torque or velocity. 

My drivers are Advanced Motion Control (branded as Precision Valve & Automation) B12A6F-PV2. i have not been able to track down any manual or documentation for this specific drive, but i do have a general setup guide from AMC which covers this era of hardware and gives me some idea of how to operate it.

However in re reading the above documentation i think the dip switch labeled "open loop" on my drive (which is switched off) is the mode change switch, with "open loop" being velocity, and the alternative being torque. Pages 14 - 16 have the modes of operation, but my drives do not have all those options. below is an image of what i have showing the pots and the dip switches.

we do now have rpi4 apt installation, just need to follow the installation guide for it. it is built in our buildbot.

kcjengr.github.io/probe_basic/development_quick_start_apt.html

ok i have reworked keyboard jogging, it now has the following functionality and is available in the latest apt install for develop branch.

ini settings:

KEYBOARD_JOG = true
(turns keyboard jogging on)

KEYBOARD_JOG_SAFETY_OFF = true
(removes the need for the control key)

shift key + jog key will give you rapid jog speed (works in safety mode and normal mode)

jog key gives you jog speed with jog feed override slider percentage applied


Probe Basic Lathe uses the following for keyboard jogging:

Left and Right arrow keys for Z axis
Up and Down arrow keys for X Axis

(in the display section, set one of the following entries only, LATHE is for front tool post, BACK_TOOL_LATHE is for rear mounted tool post)

[DISLPLAY]

LATHE = 1
(this makes X Positive direction jog key the down arrow key)

BACK_TOOL_LATHE = 1
(this makes X Positive direction jog key the up arrow key)

I think these all make sense and follow the linuxcnc std a little more closely!

Best Regards,

Chris
