Beginners help need with CNC
« on: May 04, 2016, 06:33:49 PM »
I just setup a machine and set my soft limits which work fine. I jog my machine over towards the middle of the table and load a simple gcode of a 2" circle just to see if it runs and I keep getting soft limits warning error. Please advise, thanks.

What are the dimensions (x,y,z max travel) of your machine and what do you have your soft limits set to?

Dimensions:
x=50
y=96
z=6

Soft limits set to:
x=49
y=94
z=2

Is the machine homed first?

Did you set a start origin and regen the toolpath?

I have had this error a lot and its always fixed by doing these two things, for me at least - it's telling you the code is trying to move the X beyond what it thinks it is capable of but usually because it doesn't know where it really is;)

Fingers crossed :)

Until it's homed the limits won't really know where the axes are you settings are similar to mine - 2mm under max travel, do you have a slow-down zone set as well, you will likely need it but best set by trial and error.

Still not having any luck, this is the process I've been using after watching this youtube video  https://youtu.be/08qK4NfnXqA?t=266

Jog to center of table


Zero out


Regen Toolpath


I'm getting a soft limits warning on the z axis, but I have my soft limits set to -5 inches which should be enough for a simple circle file I'm trying to cut which says only .75" on the z if I'm reading it right. (I would upload the circle file I'm trying to cut but don't know how)

Its still being told to go somewhere it thinks it can't.
Is it just Z thats faulting now?

That code appears to be from Vectric, check the end of the code to see if there is an M05 line, vectric seems to leave these out which is odd, my one did anyway.

You should be able to post the code file as you did the pictures - add attachment, maybe change the file name by putting your name in front etc first, or open it in notepad and screenshot it if its a short code.

When you home Z is home at the topmost part of the travel?
X&Y zero at front-left corner?

What's your safe Z set to in your Vectric program?
If you're not sure where to find it, it's under the "Material setup" in the Toolpaths tab.
The safe Z is set under "Rapid Z gap above material" and "Home/Start position".
If this is set higher than your soft limit distance, it will give an error when you hit cycle start.
