thanks for the reply I did not get a notice you had replied sorry for the delay in my reply.
I will give that a try in the morning. I am using all single motors for the axis. My table config is that the Y is for the across table motion, which is used by some but others use that direction as the X. (: (:  Not having the Y to home will make it so I will not need a home/limit switch for the rotary and I can jut switch the motor signal cable from the controller to the Y or rotary servo.  (:  (:   
 

I find it odd that a computer cannot populate a memory location with a value entered.
Goes against 65 years of experience.

The Z0.511 error is actually disconcerting.
I tried increasing the precision value from 3 to 4, still strange results.
Note that the errors are either very small, or only arise when setting the Offsets.

Touch-Offs prior to program Run are good.
But, that means I cannot rely on the Offsets.

Hi everyone, I'm reading this post from the beginning because with the search function I didn't find what I need (I'm on page 66 now)to be able to do a firmware bck and then connect the j-link v8 segger and flash.
I have a nvem v5 with rt1052.

Unless I'm misreading your response, you might want to buy a single drive and test the IO response speed with the actual hardware you intend to use before committing to buying a complete machine.

The other thing to consider is that nobody outside Tormach knows exactly how they're doing stuff behind the scenes with PathPilot.  They've not released the ethercat version of PP to the opensource community (yet?), and what little I've dug in to the non-ethercat version of PP indicates it's really, really different from standard LCNC.  Lots of python-based stuff, not as much HAL/INI.

I'm pointing this out because you're not as likely to get much help from this forum if you're trying to modify a 1500MX, whereas if you stick with a standard LCNC installation and some ethercat drives you'd likely find some assistance here when things inevitably go sideways.

I am glad.
And i am fully aware of the pain and suffering those types of injuries incur, been over 30 years i messed my spine, still hurts more or less, over 20 years since i messed my knee still hurts daily, elbow, hand, left foot, etc etc.
I learned to live with the pain to the point of not noticing most of the time while working, but any strain reminds me. Luckily, it has not stopped me or even slowed down a bit...well maybe about 10% slow down in general.

Then on the other side of the spectrum you have this

if you're referring to my back it's as good as it is going to get. I have to be careful how much I lift
because If I do to much weight I could inadvertently start loosening the screws. For the most
part though I'm good.

Thanks for that great info on the drives, I hadn't identified the model yet.
I'm diving deeper into the user manual/electrical prints. They are pretty well done. tormach.com/support/mill/1500mx-documents

The prints confirm you are right on all counts. They are getting the I/O from the drives. The I/O board is called "Tormach Servo IO Breakout". and its connected to each drive with a cable.

And the axis drives are listed as:
"Inovance SV660N, AC Servo Drive, Ethercat, 220 Vac, 5.5 A, STO Function"

I'm likely going to add a 4th axis anyway. So either 5in 3out more will be enough for me, or I'll just buy a Beckhof module like PCW mentioned.

I'm sure I could repurpose some of those existing 25/15 I/O, I'm not going to have flood coolant, for example. But it would be nice to leave the factory stuff alone as much as I can, just for simplicity.

I also noticed the ATC option, which I was going to get, looks like it gives 2 more In and 1 more out unused. It looks like I've got plenty of I/O options.

Thanks for your response!
