Thanks for the idea. When I ran a few simple tests with no effect. I'm not sure how to test for emi. I expect if there was some my test would have had a reaction change but nothing changed. I moved the VFD as far away as I could and added a grounded makeshift shield.

I never thought to check that. I do have a filter on the VFD power. I will move it and see if that changes the problem.

I just went ahead and ordered the 1500mx. I had to get things rolling. It's gonna be an adventure!

As I said in the top post, my fallback is to use the same yaskawa PLC I did last time as a control. Last time it was a purpose built machine, this time I would have to rewrite my code to work on a mill layout. But I still have the backup of a simple UI coded for an automation direct c-more HMI. It has data entry boxes for operators to enter numbers for triming geometry. those get stored in memory and then applied to the motion control code in the yaskawa mp2300.

I just think it would be nicer and more dynamic to have a CNC control through. Hopefully I can make some flavor of LCNC work for me.

What does this code?

Is Electromagnetic noise from the VFD ruled out?

Hello,
I am scratching my head for days trying to solve a spindle problem. I have setup 2 other mesa boards and everything was fine.
When I attempt to start the spindle (M3 S12000) or click forward in the GUI the spindle starts then stops about 1 second later.
I did have On_Abort_Command setup and it called the abort which is the only thing I can get it to log. If I change the VFD to manual control the spindle works fine. Testing the 10V spindle out seems to be fine for the 1 second then drops to 0v. The machine almost always goes to "Machine Off".
The only differences to the other machines is they have dual Y and the size of the VFD.
I ran pncconf to setup a blank 3 axis limited machine for the 7i96s, axis work fine but spindle still causes the machine to reset.
My hal and ini are a mess from testing once I clean them up a bit I can upload them if needed, they are out of the box from the pncconf.
Motion seems to be fine, limits are working. I went through the .INI and .HAL line by line comparing all spindle items and found them to be identical. But of course the others work and this one faults.
