Soft limit problem - Mach3 + SmoothStepper
« on: May 27, 2009, 12:57:47 PM »
Hi,

I have read a few old posts with questions about problems with soft limits, but I didn't find an answer on my problem.

I'm using Mach3Version3.042.027 and SmoothStepper on my milling machine.
After I start Mach3 and send axis in home position, all soft limits work fine - also by maximal speed.
With manual moving isn't possible to exceed soft limit.
If now I start one of the program, soft limits are not working any more. Nor if the program was interrupted because of broken tool,
nor if program is finish normally.
Only if I press RESET button soft limits are working again.
This is in my case a very big problem, because my Z axes has only 115 mm and is very quickly on the limit.

Is there any possibility to solve this problem?

Are you using the latest plugin? I have not noticed this but I will test tomorrow and see if this happens to me.

Tested it out here with both the plugin I had installed and also tried with ogb and both seem to work fine.
Can you attach your xml and I will see if I can find a problem there.

You seem to have the soft limits set up in a strange way, try setting the X and Y min to zero and see if that helps. Also your Z axis seems funny but maybe that is just the type of machine, what is it and are all of your Z moves positive (in machine coords) as the norm is for all Z moves to be a negative value.

I have set soft limits also in positive range, but still nothing.
Soft limits work fine until start of NC program, when program is finish (or if program is stopped) they are not working any more.
After pressing a RESET button twice they are working again.
