When an Estop isn't an Estop

[tmarks11]

It doesnt make sense that the e-stop doesnt stop the spindle. Check for a jumper on the contol board, or the spindle drive that there is a input for e-stop. Is there a brandname on the control?

He had to swap out VFD's, and the new VFD isn't programmed correctly, and the company hasn't been much help to get it programmed correctly. Apparently the estop commands the VFD to stop the spindle vs. securing power to the VFD. Good and bad in that approach (good: spindle stops faster. bad: if the VFD is haywire, the spindle might not stop).

INVT brand.

Here is a video of the estop problem

Obviously an omission by the MTB, if a commercially made machine then the spindle controller should be fed from a contactor, on which the e-stop relay should drop out.

That's no excuse, it's just a matter of common sense design.

No, it's not an excuse, but it is a reason. Buy cheap = buy crap, or at least be prepared to do some extra work.

I don't understand people whining over the eBay and every Chinese seller. Stop buying from them and the problem is solved.

That's no excuse, it's just a matter of common sense design. Our Shopmaster machines cost less than 5K each and they have an E-Stop that kills all power to the machine, besides having individual switches for the spindle and CNC system. Plus you can hit reset on the touchscreen in Mach 3 or the escape button on the keyboard and it will shut off the spindle.

OH I see. So how is that the manufacturers responsibility? No service from them is a choice they make. They wont be in buisness long with that but the spindle issue is on whomever changed the spindle. If the owner had it changed then its up to the owner to fix it. What am I missing?

Because it is a US company that sold it, I paid a premium over buying it direct because I wanted support with it and I figured they would of "improved" the machine and had it made to better specs. I probably paid double what buying it direct for. Tormach is a Chinese machine but it has great support and they had it made to their specs.

It is straight from the factory like that, machine is less than a year old, still under warranty (for whatever that's worth)

I thought you had the spindle changed.

They sent me a new VFD (which wasn't programmed) to swapped in and try and it was swapped back out.

I am a bit confused...

If it is bought from a US company then blame that company. THEY are responsible for what they are selling, THEY are responsible for that the regulations are followed.

No, I am not saying that everything Chinese is crap, but normally you pay more for what is better made or better supported, even if it is made in China.

He is blaming the company. While it might be "cheap" compared to a Haas, $20k (or so) isn't cheap by many peoples definition.

If you save $6k and buy off Alibaba, you expect crappy after-sales support. When you buy from a US importer, you expect them to support their product.
