I have a LocoCNC TAIG using 2Linc engraving software for GCode generation (rotary enabled).   The machine is all servos with Gecko controller etc. and I've had pretty good luck running most all of my other code.   Also added some filter caps on my encoders as per MFG recommendation (to eliminate noise etc.)


My test program is a simple three lines of text that I want to print three lines across a cylinder like this.   I'm not going around the circumference just want to test out the ability to engrave larger letters left to right and check depth around the tube to make sure all is well.

It starts to run and acts fine but will always bomb out and throw an ESTOP on the Z axis.   Crazy!!
I have searched through the forums and I think I will try out the "debounce" settings next.

Your code seems to be OK - it runs through on my setup without stopping.

Generally unexpected estops are electrical noise related. Are you using screened cables for your switches etc ?.

Tweakie.

By screened do you mean shielded?

Yes Sir, shielded. (I come from the other side of the pond).

Tweakie.

I'll have to take a closer look when I get back to the shop.   I'm guessing they aren't, just your basic grey insulated computer type cable.   I did do a capacitor upgrade to the encoders to knock out some noise.

I can run most any other code with no ESTOPs but it's without the A axis running.   I also can disable any AXIS on the controller, did that and ran through the code fine with each one enabled and the other ones disabled.   So maybe the addition of the 4th axis introduces just enough more noise to cause trouble.   What is troubling is that it's not what I would call intermittent or unpredictable.   It will fail in my code at EXACTLY the same place every time.    That's why I'm thinking it's something other than noise.  not sure . . . .

Is your power supply up to the task of powering all axis at one time?
Hood

I think it's 600W.    I'll have to pop the hood and see what's in there.
