Hehe - Guess I shouldn't be surprised you know as much about web protocols as you do CNC machining.

All above my head, but I'd love for the forum to keep existing. Would be a shame to lose this pool of knowledge, as well as future contributions.

Thanks for all you do!

I guess I am questioning if there is drift in mechanical home. I know it's located by the machine using limit switches, so should be very closely repeatable.

The HD-100 controller displays both the spindle position relative to Mechanical Origin, as well as the spindles position relative to your workpiece coordinates.

What's weird to me is that after the machine reset, it read "Workpiece Coordinates" as X0 Y0 Z25 (or some height I had left it at between ops). The spindle had not moved, and the relative coordinates of workpiece origin were correct at 0,0,25 (because that's where I had left it).

So, the spindle, which did not move/was not moved prior to re-homing, was at the workpiece origin I had set, and display read as if it was there.

When I initiated the homing cycle, something got thrown off. The relative position of the user set origin was not actually at the same point in space as it was before.

The only reason I can imagine for this is the the mechanical origin is not repeatable - as in, it can vary between re-homings of the machine.

In any case... I'll need to do some tests to confirm my suspicions. Maybe "something just happened"!

I do like the tip of writing down the relative position of my set origin before I start running cut files. Wish I had done that so I could fully determine if there is drift in home as I suspect. 15mm seems excessive.

Do you have a shop or something? Your projects sound neat!

 

Hey all,

I've had two instances now where the HD-100 controller unintentionally resets.

First time was static electricity that reset it. I was done all my cutting for the day, so wasn't a big deal.

Second time I simply pulled the pendant out of the cradle to insert the USB key with a revised file. The machine reset itself.

Controller prompted me to re-home the machine. I did not, as I didn't want to lose my workpiece origin. I was running multiple ops off this origin.

It wouldn't let me start the file, so I eventually let the machine do the homing cycle.

I was hopeful it would keep my workpiece origin and it seemed like it did with a quick visual check. Unfortunately, it absolutely DID NOT (Z was way up, so seemed closer than it was). When I ran the file, the origin was offset about +15mm in X and Y.

This really cause A LOT of heartache. The part being milled was one of a kind. Without the last op, it did not work as intended. We have no way of knowing if the last op would have made the difference.

Honestly, I'm furious. I NEVER want this to happen again.

Any suggestions?

Thanks,

Paul

I was curious about this too. Simply assumed that referencing had to be redone every time the machine was homed for absolute accuracy/repeatability (+/- 0.005). Good to hear that is likely not the case.

drew - do you know if Phantom has published their maintenance guide yet? I'd really like to have this. Only maintenance advice I've had is:

1) Don't use the auto oiler

2) Dribble (drop?) some 10W-30 motor oil on the ways once in a while...

Congrats! How do you like it?

Assume you figured this out but:

Hit "Menu"
Select "Machine Parameters Setup"
Select "Tool Measurement" (option 12 of 14 - you need to scroll down beyond what is visible at first)
Select "Sensor Block Thickness"
Set to new value

Ours was off by ~0.040

Not an expert, and really not sure if this will help, but you may want to adjust your puck height in the controller. Ours was ~ 0.5mm off.
