  • to "HomeLimitAll" if they all go to one input
  • to "FirstAxisHomeLimitOk", ..., "ThirdAxisHomeLimitOk" if all switches for a specific axis go to a single input
  • if each switch has its own input, then assign "{First/Second/Third/Fourth}AxisHomeLimitOk" to the switch that will set home and the appropriate version of "{First/Second/Third/Fourth}Axis{Plus/Minus}LimitOk" to the other switch on the axis.
To say exactly what you need to do, we will need a new report from the machine.
Thanks for your help here. Have had a look and the machine is set up as follows.

Will post a report from the machine as well.
Please reread the post from Centroid, Your inputs are not setup they way they suggested. You need "FirstAxisHomeLimitOk", etc. Your's are just set as home switches and not home/limit switches.
Hi there, thanks for that. I had changed the inputs as suggested and it the wizard noted that I cannot have a limit_all under input 7. Been trying to figure out the wiring for the machine. Will go and read the manual again and try and trace the wiring for input 7. Does not seem to go to the limits. In case it helps, the report file from the machine is attached as well. Thanks for all the help. Cheers

Thanks for the report. Several issues to note first, you are using 4.8 which is very old, with known bugs, and no longer supported. You should install the latest version which is 5.1 for free support.

Please post a CURRENT report from today or maybe from the last week if you have one. The report you uploaded is over 4 months old.

Remove the "limit all" from input 7. It's not needed right now and really not at all. You can set up "soft limits" in the Wizard for your max travel. No switches or wiring needed.

Set inputs 1,2 and 3 correctly because they are still incorrect in this report. If you've changed anything you should upload a CURRENT report for better help.

Your "steps per revolution" settings in the wizard are incorrect. They can never be 17,143 or 18,751 like they are now, they are simply wrong. Those values are either 1600, 3200, 4000, 6400 or even 8000, etc. They will ALWAYS be a whole number. It can never be the value you have it set at. This value MUST also match the settings in the drive. What servo/stepper drives are on the machine? Please start a Google album and share the link here. Take a bunch of pics of the control cabinet, drives and limit switches so we can see what you are working with.

You MUST correct the drive setup problems before you go any further. Set the steps per revolution correctly and the drives to match. Then you can proceed. A software updsate is recommended but if you choose to stay with 4.8 you'll have known issues.

Shawn. Thank you for the reply. Will go and digest this. Apologies for delay getting back to the post, have been travelling. The report was only a few days old. Will check pc as suspect date setting are out (not connected to internet).

A lot to unpack here but will start with an update and setting as limit and home and see where this takes me.
