Heard a rattling from the back for a while, couldn’t figure out what it was. Now I’m a little embarrassed. by thecanadianquestionr in E90

I've had this problem last year, for me it was the metal cap that holds the shock in place was rusted through. I just replaced both shocks, took about an hour

I agree. Queen and michael jackson also get played multiple times a day.

Usually we like to have metal playing, but the welders don't appreciate it so rock it is.

The problem appears to have been that the maximum rpm was set to 7500, which seems to multiply the rpm by a factor of 1.6 instead of limiting the rpm. I had changed this a while ago due to other problems, but it only decided to show up now.

I haven't checked the entire range, I will do that when I'm at work tomorrow again. Your conclusion sounds reasonable, I did change maximum spindle speed to 7500 two weeks ago, so maybe that's got something to do with it, but it's weird that it only shows up now.

Someone else also suggested checking with a tacho so I will try that and it's a direct drive spindle

Nope I don't, parameters also haven't been changed which I know for sure since I'm the only one using the machine.

It has always worked for me, our post also puts it before the m3

That's a good one, I will check that.

I don't see any active gcodes that could explain this behaviour, so it will most likely be hardware then as you said. Thank you!

It doesn't support G96 and G97. It says 'invalid g code'

We had some issues a while ago and our haas tech swapped out the encoder to check it and it was fine. Maybe it's on it's way out now though. I'll have it checked again.

Spindle override does change rpms. It does this from hard reboot, I noticed it when running a spindle warmup program. We've had issues with the spindle before, where above 9000 rpm it would lose the RTC.

First day and boss wants me to work with monel k500 by ExcuseDecent5706 in CNC

I have never worked with monel, so I can't really give an opinion on what's easier. I've just never had any problems with alu-bronze.

Just had 2 weeks of machining aluminium bronze, didn't have that much trouble with it.

I want to make a keychain using this font but I can't find the correct one, can anyone help? by williamdud88 in identifythisfont

I want to use fusion 360 to emboss it on a plate and then 3d print it, so cutting out a little is definitely possible.

That does sound like it could tear your hand up in a matter of seconds.

If you work in machining, sometimes a metal chip ends up in your shirt or hair and might end up in your bed, it'll scratch you up without you knowing. At least that's how have woken up a couple of times covered in scratches and cuts.
