Help and Support / Re: HD-100 - Random Resets and Origin Loss
« on: December 19, 2023, 01:03:32 PM »
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!

Drew, I appreciate your response, and apologize if I came off as a bit... mad, hah.

I'm going to call Phantom and see if they can help re why it happened. Maybe get some tips on grounding, though I assumed this would all be done. (Power to the machine was done by an electrician, I'm not super familiar with the concept of grounding, but assumed it could/would all be done via the power input.)

Regarding coordinate recovery, a few questions:

1) After reset, which happened when the spindle was sitting above the origin at X0/Y0/Z25, workpiece coordinates still read 0,0,25. As the machine was homing itself, I watched the DRO on the workpiece coordinates move with travel of the machine to home. The piece was a bout a foot into the bed in X and Y, and the DRO for workpiece coordinates read ~ -250X / -300Y once it reached mechanical home. So I figured every was copacetic.

How would a G offset behave any differently? Are the G offsets not relative coordinates themselves?

Is it practical to setup G offsets for one-offs? Sincere question - I haven't played with them much.

2) I did consider writing down the mechanical coords once my origin was set. Is there a "Go To" type function in the HD-100? E.G. Go To 250,350,30

I'll run some tests when I find them time, maybe running some hole patterns where Mechanical Home = Workpiece Origin. See how consistent it is between resets.

Thanks for your help Drew.

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?

Yea I know what you mean re: mechanical home. I guess it goes back to Sam's question of how consistent that position actually is relative to the rest of the bed. I'm gathering that it is precisely the same every time, which is great to know. I was worried it would potentially vary by a few thou time to time.

Probing would be great, but no time or money to figure that out hah. 99% of the time we're cutting with wide margins either way.

We have an SCV44 with the HD-100 controller. Besides static discharge causing the machine to unexpectedly reset once, it's been pretty good.

I think I prefer the HD controller to the DSP, though I've never used the DSP.

Thanks for your help drew - hope the guys at Phantom are treating you well!

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...

I have been following this issue, and while I REALLY appreciate this forum and it's extremely knowledgeable and helpful founder (drew), just wondering if Phantom Technical Support was contacted about this?

If so, curious if they've stepped up to help.

This seemed like a forum conversation until mention of sharing machine parameters files. I'd expect Phantom to facilitate a hardware "flash" and to have the correct files to send me promptly based on the machine I purchased.

Congrats! How do you like it?

congrats! people here can help  :)

You're going to love 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

Smackey Would you share a photo of how you connected the line together? We use the air, so would be great to just close the rollers and keep the air stream.

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.

Yea we did remove them, just a bit jarring to have the pistons going up and down all the time haha.

Is there a way to disable to rollers on SCV44?

brewvet63 Brandon from Phantom told me not to use the reservoir on the SCV44. He recommended applying a few drops of any 10W30 oil to the ways (a few dabs along the length of each silver track). I believe he said every week or two... obviously varies on how much you use the machine!

Would love a comprehensive maintenance schedule as well if you find one!
