4th axis angular need help from newbie!!! was created by libas77
Hi,
I built my 4 axis linear hot wire cutter (X,A axis horizontal, Y,Z vertical movement; X,Y right and A,Z left side). I am going to cut wings on it. I use motor driver board TB6560 ( is not the best, got to late) . I used for controlling the machine mach3. I didn't want to pay mach3 license for cutting wings for max. two aircraft per year. Therefore I decided to switch to linuxcnc (version 2.5 Ubuntu 10.4).
I configured in stepconfig 4 axis X,Y,Z A limit and home switches. I am able to home all axis but:(current Issues)
First Question
There is something wrong in my configuration one of the axis runs angular the remaining axis run linear. By homing the axis one motor sounded strange. All axis should run linear. What I have to change? ( ?change stepconfig INI file? How?)
Second Question
I had a issue in mach3 with motion mode. I had to switch from exact stop to constant velocity. Is there any configuration in linuxCNC for motion mode - constant velocity?
Thank you in advance for your help

Hi
1. The axis type must be set in the ini file. A defaults to rotary
www.linuxcnc.org/docs/html/config/ini_co...tml#sub:AXIS-section
2. I don't know what 'constant velocity mode' is in this context. That is Mach terminology presumably.
Suspect that as you refer to 'exact stop' in the same sentence, what you require is G61 or G64
www.linuxcnc.org/docs/html/gcode/gcode.html#sec:G61-G61_1
regards

These machines are normally set up as XY / UV machines.
Try looking at the sample config sim/axis/axis-foam config to see a sample setup and how Axis can accurately display the foam-cutting process.

Hi,
I have just normally set up as XY / UV. I found a tutorial here : code.google.com/p/emc2hotwinch/ Due to some issues I can not start linuxCNC now. See below.
Attached you will find the horkydraht.hal and horkydraht.ini and a file with an error message.
Could you anybody from you check the .hal and .ini file there must be a bug.
Thank you very much
best regards

horkydrat.hal:7: Ini variable '[EMCMOT]SHMEM_KEY' not found.
that is the problem.
In your horkydrat.ini file under the [EMCMOT] section, add the line
SHMEM_KEY = 111
unfortunately, motmod (the module defined under [EMCMOT] doesnt have any info on the manual page about the key parameter.
So I'm not sure exactly what the number should be, but 111 seems to be a popular number.
If that doesn't work, you can try removing the "key=[EMCMOT]SHMEM_KEY " from the second line of your .hal file.

The "motion" module hasn't needed the "key" parameter since LinuxCNC 2.4. Just delete the reference from the HAL file

Nothing attached
Start linuxcnc, get the error and then run dmesg > dmesg.txt and attach the resultant dmesg.txt file
which will attach OK
