Hey I got everything working. Turns out I was getting signal interference on my USB cable. I moved it to a location away from everything else and haven't had any problems since. Thanks for the help, the programming changes worked perfectly. Thanks again!

I figured out how to modify the screen load script. Changed the code to make it Ref X and Y individually, but now I'm getting this error code. I don't think any settings changed on X or Y since I had the RefAllHome working with all 3 axes. Thanks

Ok, it looks like just changing the home order to 0 on Z didn't work. I need to edit the screen load script but I don't know how to do that. I can see it on the operator tab, but I don't know where the file is to actually edit it. I know this is a very basic question but I'm new to Mach4 and haven't needed to change much since I upgraded. Thanks

Wow, you're right, I can't believe I didn't think of just setting the home order for Z to 0, haha. Thanks for the help!

Hi,
Yes, I have home switches on my X and Y axes. For the past year I've used the switches as they're currently configured as home switches. Now I want to use the switches on my Z axis as limit switches only. In the future I'll probably add a third switch to do homing on the Z axis, but for now I don't really need to home the Z axis, as I typically rezero between operations or tool changes anyway. Thanks

Thank you for your concern about my limit switches. I very much understand the importance of limit switches, and if I could, I would put all of the limit switches on every axis. Rest assured that I eventually will put the correct amount of switches on my machine at a future date, but until then I just need it to work, and part of that means having RefAllHome on only the X and Y axes. If you know how to modify that code and would like to tell me how then I would really appreciate your doing so. Thanks

Okay. Thanks for that, I'll keep that in mind.

So about modifying the Homing script...

Hi Craig,

Yeah, if I could get this figured out by the time I go back to work on Friday that would be great. I'm sure it's an easy change, but I haven't been able to find any guidance on this specific topic. Also, I was hoping to get some clarification on how to use a limit switch as a home/limit switch. Everything I've tried so far has resulted in Mach 4 either not being able to jog, or crapping itself and running past the switch and crashing. I have a Bridgeport Series 1. Z axis has separate limit switches which work fine as limit switches, but with the switch set as a limit/home at the same time, I can't RefAllHome without bad things happening. With the Z switches set as limit switches, I can't ref the other axes home, hence the need to change the RefAllHome script. With the switch set as Home only RefAllHome works great, but then I don't have a limit switch which is obviously bad.

On a related but separate topic, my X and Y axes each have only 1 limit switch that trips at the extents of travel. Mach 3 was smart enough to recognize that a limit switch triggered moving in one direction was either a -- or a ++ depending on the direction of travel at the time the switch was triggered and allowed you to jog back off of it. So far I haven't figured out a way to use only 1 limit switch as a -- and ++ limit switch. I never used the homing function when the machine was set up with Mach3, but I'm certain that the limit switches were operational the way I described. It sure would be nice if there was a way to use 1 switch as Home/--/++, but maybe that's impossible in Mach 4 and I need to lower my expectations. Thanks

I would like to modify my Mach 4 RefAllHome script so that it homes only my X and Y axes and not the Z axis. Is this possible? Thanks.

Mach4 General Discussion / Re: Help! Error Message G81 Cycle, Z Value Unspecified Error

« on: December 08, 2017, 12:47:52 PM »

Thank you! I left the first line the same but removed each subsequent G81 like you said and it runs perfectly. I don't know how long it would have taken me to realize that that was what needed to change, but I think you just saved me at least another hour of banging my head on the wall.

Now I'll need to update our Gcode generator program. It's a program that my coworker wrote years ago that lets you pick points and polylines in Rhino3D and it spits out a Gcode. Anyway, thanks again.
