Need help with Z axes, everything was running good. I have the Elite Woodworker.
When running a program that has 3 tools after the end of the second tool program the z when up and errored. I rehomed and Tried to run the program and each time I start the program the z goes up past the limit and errors. I load a program that was run many times before and the same thing.
I checked all the cables and connection’s. I rebooted, rehomed, many times.
It will run fine in simulation mode but as soon as I run any program the z goes rapid up and errors.
Any ideas?
Is this after the 2nd tool always?
Did you chnage your z height in the different tool?
Is your start depth different?
Is your safe z height different?
Sounds like some part of the program is attempting to travel the tip of the cutter outside of the Z-travel area.
Did you recently repost the file? You may have added in different Z clearance/retract.
Did you change tools, and put in a shorter or longer tool? Or have the same tool extended from the collet a different amount?
Did you accidentally set Z=0 is a incorrect spot? Pretty easy to accidentally zero the z when you intended to zero the X or Y.
Check that the position Masso “thinks” Z=0 is actually is the Z=0 position. Do this by jogging the cutter to the Z=0 height, then look over at the Masso screen and double check the listed Z-value is 0 (or very close to 0).
Also note: the error isn’t necessarily at the moment in the program when Masso shows the message. Masso reads ahead in the program, and will throw the error if it sees a motion outside of the limits sometime in the future.

I load a program that I ran many times before.
1 home the machine.
2: zero my x,y,and z. to the workpiece.
3:rewind and hit program start.
The z stepper jumps up and stepper alarm flashes before the x and y moves to the work origin.
I think I can rule out the program. this happens on all the programs that I used many times before.
The first error happen at the end of a program when the z rises and before it moves to the front center to change the tool.
I also think the problem is unlikely to be the program.
Check that your Masso is still operating in G54 work coordinate system (WCS).
The top of the Masso display shows with WCS is currently selected (G54, G55, G56. etc…).
If, when probing you accidentally set it to something other than G54, then probed, it could behave this way.
Have you looked at the G-code for any weird Z movements? Feel free to post the code for us to look at.
Can you separate the various toolpaths each into their own program, and run them one at a time to see which one is the culprit?
Also double check your Z-homing sensor isn’t obstructed in any way. If, then homing, something falsely triggers the Z homing sensor, like a wire or chip getting in the optical sensor, it would mess up Z-limits.
yes it using G54 offset. my setup screen has the offset set to x10.4670 y 3.80669 and z is -0.21398.
this is something I never change.
I disabled the auto tool zero.
I set my Z,Y,and Z to a random location and if ran!
I reloaded the program I was trying to run, reset the work origins and it cut with no problem.
The only thing I notice was it did not slam up to the z when the program started.
I don’t know if its the auto tool zero or if it just started working on it’s own.
I will run some more test.
