[SOLVED] Weird problem with travel table

Hello,

My X-axis has a range of 300mm, my Y-axis a range of 200mm.
I set these values in StepConf Wizard (X: 0 -> 300 and Y: 0 -> 200) and homed. These things works good.
But when my axis moves to 0 it fails, the machine reach 0 but LinuxCNC not and continous.

Somebody who knows a solution?

Hello,

Are you using home and limit switches?
You might want to attach your configuration files.

Yes I have only home + limit switches and they are on the end of each axis (maximum).
Do I also need to add limit switches for the minimum of each axis then?

you have a number of options , but not knowing the type of machine you have , here they are

1 add limit switches to minium end of travel
( you only need one switch to act as limit and home )

2 set homing to move to + limits and then set the offset to show positions to be 200 and 300
you would then be able to set a button in a pyvcp panel to move to 0.0
this is set in your ini file for each axis , see the entrys for HOME , HOME_OFFSET and search and latch , examples are in the documentation linuxcnc.org/docs/html/config/ini_homing.html

You actually don't need limit switches on both ends though it is recommended.
Once you have homed properly, linuxcnc will not let you move outside the software limits.
Now if the hardware fails to follow commands properly....

You say linuxcnc doesn't get to zero and continues? You mean the machine continuous to move but the Digital readout doesn't?

Config file would help.

I found it... I used G53 G0 X0 Y0 Z0 to get again on zero.
But I think LinuxCNC didn't home propely and that's why it fails...
