Why do you need to use a manual handwheel?

Wouldn't it be possible to move the axis solely via CNC control?

What is "The following error"? You don't print any error message after that statement.

An idea:
You could connect a rotary encoder wheel and configure LinuxCNC so it behaves exactly like the handwheel, but drives the axis via the motors and CNC, without directly, physically moving the axis itself. It'll also save your shoulder from the strain of turning the handwheel and allow ultra-precise movement too.

I'm sure that the functionality you describe is possible, but I'm sure there must be some easier workaround for this problem.

Cartesian axes:
Refer to movement of tool
Standing in usual operator position, e.g. in front of machine


For vertical machine centre
X+ tool moves from left to right
Y+ tool moves away from operator
Z is axis inline with spindle rotation. Z+ is moving up
(just like an x,y,z 3D graph)

Z is always inline with spindle, so axes naming is "different" for a horizontal machining centre or grinder.

I did a reeinstall removed the raspi part like hakan suggested and everything worked. I will try to connect my ethercat devices tomorrow
Thanks

My DMU50 looks kind of like this. That model is at least quite common i think.
 


Here's a fancy sales video of a 'newer' version of mine:  DMU 50 3rd. Generation

Sorry, this is a Button at the Probe Basic GUI

 

Furthere more where can i decrease the "G0" speed? 

 

Was ist "go home" ?
A button on the GUI?
Probably by editing that button from G53 to G54 Fxxxx ...

Hello,

today I did the steps from tommy`s link.
At the end i played around with the P and FF1.
After arount 50 different tests, slowly the hard errors dissapeared and at the end i found the best working configuration with P=15 and FF1 =1

So I configured this parameter on all 3 Axes and it works.
Only one last problem is the speed for "Go To Home"
Is ther a info where i can find the different settings for all moves?
Jogging Speed is OK and i can change ist via the GUI.
Homing Speed is also OK, but "Go Home" is far to fast.

Best regards
Jens 

Here is my config (with working Linear-Encoders​ & Closed Loop Stepper)

Assuming it has analog servo drives and those work, you would need an analog Mesa card, preferably Mesa 7i97T as it has analog outputs and encoder inputs all on one card, and a few I/O for limits and relays.
It is an ethernet board, and there is no practical difference between PCI/PCI-E/ETH cards except ETH cards can be mounted wherever is suitable on the machine as the LAN cable can be quite long, while DB25 cables are limited to about 1.5m (there are 3m and 5m ones but will have to be very good quality to work).

The Maho should (or should not?) have some EXE boards that translate the signal from motor feedback to encoder pulses that Mesa can use. This is what i've learned fro reading here on the forum, i do not have a Maho.

You are welcomed, always.
And as a general rule, edit machine files only with simple text editors, anything else will add special characters to the files making a mess.

Try

Parallel port in mode OUT (normal mode):
OUTPUTS
1, 2, 3, 4, 5, 6, 7, 8, 9, 14, 16, 17
INPUTS
10, 11, 12, 13, 15

So, just to side track a little....

Where would you stick the control? Assume the machine is open, cause its a wood machine.

Would you put an arm on the machine frame, our would you put it on the stand? I feel like cause the stand is optional/variable, mounting it to the machine is better. off to the right side (viewed from the front) vertical 15" capacitive touch. with a little printed housing for a clusters of physical buttons and e stop.

Thoughts?

ЧЯДНТ? What I Do Wrong?

Grazie per la risposta,
Si, si tratta della funziona Hal. Ho letto come impostarla, ma sono in difficoltà nell'imdividuare i piedini della parallela. Pensavo di usare il p. 12 come ingressa di M8, il piedino 3 come segnale di PAUSE, e il piedino 13 come segnale di RESUME. Sono segnali TTL in uscita da un integrato cd 4017.
Un saluto

 matrixkins is a standard technique for correcting the curvature of the portal in the LinuxCNC 2.10 kernel (and above). The issue of mutual correction of XYZ coordinates is resolved by specifying correction coefficients. However, this component is provided for single-engine machines, i.e. XYZ schemes. To use this software correction, changes must be made to the ini machine configuration files. Hal file does not require correction. MAN does not give these examples, см. github.com/LinuxCNC/linuxcnc/blob/master...ents/matrixkins.comp. However, in the ini file 
instead of -
KINEMATICS = trivkins coordinates=XYZ
set -
KINEMATICS=matrixkins
then explicitly specify non-zero correction factors, for example -
halcmd setp matrixkins.C_yx -0.00252427184466  

You will find the coefficient values and the transformation matrix in MAN.
The halcmd setp matrixkins.C_yx correction command -0.00252427184466 can be executed in the terminal (not while the machine is moving!), i.e. the parameter can be changed on the fly.

In case you have a multi-engine XXYZ configuration, etc., you need to change the source code of the matrixkins component (github.com/LinuxCNC/linuxcnc/blob/master...ents/matrixkins.comp), similar to www.forum.linuxcnc.org/38-general-linuxc...xyyz?start=20#338894

+ sudo halcompile --install matrixkins.comp
