1500MX "ML Serial Numbers" and probing/interfacing

I’ve been considering the 1500MX since it came out, and purchased a different used machine since, but I’m looking again, so reviewing what’s new with the 1500MX since I last looked.

I was previously saddened by the lack of nearby “MX” machines in my area, and nobody except a few sponsored YouTubers to give positive reviews. Sales numbers are a closely held secret, maybe for good reason, but I don’t want to be the only one I know with one. And I was perplexed by the “proprietary” nature of the probing and auto-level interfacing on the 1500MX, which doesn’t allow cheap generic probes or level setters to be added. (I like using cheap probes, as precision is less important than replaceability if dropped or broken.)

Now over a year later, there still don’t seem to be many machines out there. No armies of users sharing information and ideas/solutions. I had hoped Tormach would have a cheap interface, so generic probes and level setters, and other hardware could be integrated easily.

But I was going through the Tormach site, and saw that there’s now a “plug in passive probe” for $599.99 which supposedly works on the 1500MX with “ML Serial Numbers.” Not sure where this would plug in, but I didn’t think this was available last year. This makes me think a smart hacker could maybe get a cheap probe interfaced, though the same plug? Does the phrase “ML Serial Numbers” suggest an interface was added in recently made 1500MX machines?

I understand the 1500MX has a completely different electrical system, where all digital controls go through some special ethernet-like signaling lines, so a user can’t just interface new hardware. For example, the “USB M-Code I/O Interface Kit” which is listed as available for the 1100MX is not available on the 1500MX, But this type of function seems necessary to many users and gave the interfacing that made Tormach famous. How hard would it be to make a similar interface for the 1500MX?

Is there any way to interface crude/generic hardware, like probes and tool levelers to the 1500MX like we can with the 1100MX? It seems this USB M-Code I/O interface would do the trick, then it’s just a matter of making up macros to interface with the signals.

I’m not complaining. Tormach has a fine product, which is about 95% of what I need, but that last 5% is a killer. I just want to double check, that I understand things, before I buy another old used VMC.

@Thomas_Jones I am glad to hear that you are interested in the 1500MX again. We have had a busy year with this machine with strong sales and some incremental updates. Unfortunately, most of the customers buying this machine are putting it to work and don’t have a social media presence. There are a few threads here where folks are sharing notes on who has a 1500MX as well as wired probing on the 1500MX. e.g. Looking for a Tormach 1500MX owner - #4 by Roy

Probing - As for wired probing on the 1500MX, that is now an option and wasn’t when the machine launched. The reference to the ML SN’s is in relation to the 770MX as this kit will work on all 1500MX machines. If you want to use your own probe then you will need the y-cable (54753 $90) and M12 connectors (51353 $11). These aren’t directly accessible on the website and we can get them added to your quote from our end.

Thomas,

To add onto what Davie mentioned this is a brand new option that was released just before the holidays with 2.14.0. It is specifically an either/or option right now, you cannot mix a wireless probe with wired tool setter (might come in the future as well but it would have pushed back release even further).

There’s also a behavior change with wired probing with 2.14.0, if you just plug a probe/tool setter in and hit the tip Pathpilot will do nothing. You need to issue an M44/M46 (probe/ETS) command to watch for the signal. Those codes are automatically given when touching off a tool/putting T99 in the spindle.

It must be understood though that our ability to provide support for wired probing with a 3rd party device ends at the M12 connector. “How do I make my probe/tool setter work with a 1500?” or “will it work?” aren’t questions that we have the answer to and some DIY experimentation is required.

Thank you,

Norman

Hello Thomas,

Not sure where you are located. I just bought one here in Tucson AZ. I am in the process of adding a wired probe and tool setter. Happy to share what I have learned. Love this machine. Tormach tech support has been over the top… Amazing!

Thanks… Richard
