Hi, this newbie needs help. Have fitted limit switches and all work OK. However when I press the "ref all home " button nothing happens.The machine should go to all switches as I understand it. Any help would be appreciated.
-
Do you have the home switches enabled under Port & Pins -> Input Signals?
-
Hi, yes the switches work fine, they stop the machine and show in the diagnostics page. Its just that the ref all home won`t work ! :'(
-
You say they work fine and stop the machine. That implies that they are properly enabled as "Limit" switches. However, I believe, if they are not enabled as "Home" switches, you will see no motion when you press "Ref All".
On the Ports and Pins -> Input Signals page I mentioned before. Are the "X Home", "Y Home" and "Z Home" enabled with valid Port and Pin numbers?
-
can you reference each axis on the diagnostic page
-
Hi, have got m1 and m2 home leds up on the diagnostic page so will not ref.ms will ref but will not stop on the switch. Must have a serious mistake in the wiring !!!
-
check the pin numbers aren't duplicated
-
Hi, have got all three axis going to ref home but not stopping on the switches.The leds are lighting up in the diagnostics page

Have you checked this, and a reload of mach may help but make sure you either save the xml or know the settings.

Just for the future, you should try to post LazyCam questions in the LazyCam area of the forum and start a new thread.
As for the DXF issue, try saving it as an 11/12 vesrion of a DXF. Also, I personally used to use AutoCad, but had similar problems exporting. Then I switched to ProgreCad (free autoCAD clone) and I haven't had issues after that.

yes, what cured the problem, and what was it eventually.

I am having the same problem. The led's light up in the diagnostic page when I press any 1 of the 3 home switches, but when I ref all, the axis motor does not stop. I crossed checked the port and pin configuration between the c25 bob and the home settings and they are match. I am using an ESS board between the machine and computer. Everything else works fine including all axis movements. I have also tried my laptop, but the results are the same. There must be a parameter setting that I am missing? Stumped on this one!
