What Did You Buy Today?

As long as it works and you position it carefully there shouldn’t be a problem. The main reasons for the15* is to be able to have the point of the diamond touch the wheel rather the the side of the diamond.

The 15* point placed a 7:00 will also cause the tool to be pushed away from the wheel should you try to lower the wheel too much. The 40* angle could cause the tool to get caught under the wheel tip it, and violently eject it.

I’ve seen incidences where a tool was misplaced and the magnetic chuck wasn’t engaged. The tool flew across the room and hit the wall. No casualties other than a broken wheel and damaged tool.

As a side note several companies make wheel profiling tools. They are often used at a variety of angles.

Thanks for the info. Pushing the tool away from the wheel struck me as the logic for the 40* angle. So far, I've used it once, and it worked great. I'm pretty risk-averse by nature, but I'll be extra careful when using this.

Bought a precision digital scale for weighing internal engine components for balancing. They had these as low as $58, but paid $115 delivered for this one as it was supposed to be accurate to one tenth of a gram, and It appears to be dead nuts on. Also has a cable connection for printer or to computer, so should be able to feed data directly to balancing program. Mike

I was going to say that's a pretty nice box for $100!

But then you said the drawers are full. So:


LOL!

After a few years searching,... I got my hands on a 10hp rotary screw compressor with a dryer for a good price. Drug it home yesterday!
Needs a good cleaning, 27000hours, about 30cfm@150psi
Gotta love when they pop up in town.
One wouldn't believe how fast these sell....

This arrived last week... it's printing as of yesterday.



Packed really well..


A few minutes of minor assembly:


Then run through various calibrations:


Then 90 minutes in support chat. The left Z axis stepper seems to have seized since it left the factory. They say they haven’t seen this failure. Because of this they need a few days to decide what they want to do. Support had me remove all the fasteners to lift the heat bed to verify the stepper does not turn.

After a lot of back and forth in Prusa's support chat the new Z axis motor for the XL arrived yesterday. Turns out the screw is integral to the stepper motor shaft. So.. I wrapped the jaws of a pair of pliers with a microfiber cloth and put some ass on the seized Z axis screw on the XL. Of course it turned. After a couple hours of back and forth with their support chat folks, the XL was up and running. The toolchange setup is REALLY slick. The first print was a small calibration cube:





Coffee cup for scale. I'm not really impressed or happy with the support process. And, initial impressions of the XL are really good! This is where I left it when I went home last night..





This is what I walked in to this morning when I got to the shop.






14" wide, 4" deep, 2" tall. Zero lift in the corners. NONE.





First real print on the XL was as good as I feel a person can hope for.
