Knuth Mark Super CNC Retrofit - need some help with my first LinuxCNC

Category: Milling Machines

Hello,

okay thank you. :-)
One other question about the G-Code. Where can I read about the supported G-Code for Linux CNC and what kind of postprozessor I have to use or setup.
I need some bore cycles and helix in all 3 axis...

Have a nice day
Martin

I can solve above error by changing to :

#net x-home-request joint.0.request-cia402-homing => cia402.0.home
setp joint.0.request-cia402-homing true
net x-homing joint.0.is-cia402-homing <= cia402.0.stat-homing
net x-homed joint.0.cia402-homing-finished <= cia402.0.stat-homed

but the motor still not move.

Ignore hard and or softlimits for toolchange

Category: General LinuxCNC Questions

My toolchange uses two custom hydraulic rams in top z position to release the tool.
They are leaking and I am not sure if I can fix them. An alternative would be to make them fixed and move Z up to release the tool. 
But this has to be avoided during normal usage.
The reference switch is at the end of the tool change travel. So I could use this as a combined end and reference switch.
But I would need to be able to move over this point for toolchange. 
Is ip possible to set something like this up?

Thanks Patrick

The underlying problem may be that GUIs handle this differently (ie have not been updated to the new [SPINDLE_n] section) but I'm not sure.

Please raise an issue so it does not get lost.

If you are following Rods method why are you not using his 'cia402_homecomp.comp' he describes on his page?

I think that might be possible using a python remap for 'T'. The remap is executed by the read ahead and could start the tool search through hal.

[edit]

Just gave this a try and it looks like it might work:
import sys
import traceback
import hal
import emccanon
from interpreter import *
from util import lineno, call_pydevd

throw_exceptions = 1 # raises InterpreterException if execute() or read() fail

def remap_t(self, **words):
    cblock = self.blocks[self.remap_level]
    tool  = cblock.t_number
    if self.task == 0: # ignore the preview interpreter
        return INTERP_OK
    self.execute("T%f" % tool, lineno())
    print('T_Remap preparing tool: ',tool)
    # Initiate your tool prep here
    return INTERP_OK

with this in the [RS274NGC] section of the ini file:
REMAP= T py=remap_t

You will also need to configure python:
linuxcnc.org/docs/devel/html/remap/remap...emap:embedded-python

For sim config on python remap see:

Okay so im putting together a parts list to get started with this build. I put power to the driver box, tripped the contactor with a screw driver and a green light comes on the power board and fan runs. im not sure what else I could do to test it besides connecting the burny 10 back up.
So far in my parts list I have

7I83 Analog output/ analog servo interface
7I85S 4 Channel encoder, 8 differential output 1 channel Serial RS-422 interface
THCAD-300 High isolation A-D accessory (Go to replacement: THCAD2)
7I96S STEP/IO Step & dir plus I/O card

I am going to assume that I can hook straight up to the raw arc voltage of the hypertherm ht2000 with the thcad-300. Is there any advantage to a voltage divider board other then the potential risk of electrical shock? Will I need a power supply to go along with these boards? do you have any recommendations for a reliable one on my previous build I used a cheapo china one and the fan stopped working a while ago.

Oh the red highlight was for cycle start selection.
Ie in MDI mode cyclestart would run the MDI command, in Auto run the program.
It's code not ready yet, I just forgot to turn it off.

Plate centering so if a plate is set crooked on the table, you can define where it sits with 3 or 4 points. This avoids the chance that a plate is placed crooked operator error and it cuts off the side of the plate.

Is there anything special you need to use that would require building from sources and patching?
For normal stuff, it is as easy as downloading the latest ISO file, installing it, then in a terminal type
sudo apt update
sudo apt install linuxcnc
That should also install the RTAI kernel together with the RTAI version of LinuxCNC, although i have never tested it.

I think ive made some mistakes that I dont have the knowledge or time to recover, so I have found a good video to build from source and am currently working on that. Thank you for the help, but due to me I'm starting from square one.
