Great animations  :praise2:

I believe that my Alibre is same vintage - but it runs on Windows 10 now. This requires you to get support from Alibre to make it work though - glad they didn't make any fuss about it.

Gerrit I know about Feature-Creep all too well  ;)

Resonance and curing it with a change in Feed-Speed makes sence - nice to hear that it was so easy for you to fix  :ThumbsUp:

Again thank you for sharing  :ThumbsUp:   :ThumbsUp:

If it wasn't for the fact that it looks a bit too clean - you could mistake it for a full size Locomotive  :praise2:

I am using a vary old version of Alibre' 2011 with a free license for non-commercial use, running on an HP 32 bit laptop under Windows 7. I find it easy to use and extremely powerful for a 12 year old free package.  I have refused to upgrade the OS for fear of compatibility issues.  It is fun but it lacks many features of later features.  For example, it has no gear or pulley functions.  in fact, the only means to transmit movement is through cams or levers and no means to set continuous or cyclic motion.  It has no means to provide stop limits or to recognize contact nor does it have a means to define force or direction.  BUT all assembly fits are perfect, no wobbly shafts even if the bearing is oversize or missing.


Therefor, i can't simulate a release mechanism based on a knock off cam or dashpots that work. Maybe I could with a little fancy editing but...... it's what I got. It is really helpful in working out the complicated geometry of the Corliss valve linkage and testing various options. In this assembly, there are over 100 parts and about 250 positional parameters.


This post is getting too long and its getting late.  more tommorow maybe..

I am probably mixing 10:1 isoprop vs oil. To be honest the main goal is to clear chips with the air blast, esp. in aluminum.

One excellent feature of the code is that setting the flow rate pot to zero you can push one of the buttons to reverse the pump and empty the hose of fluid.

Hello Gerrit,

I like your interpretation of the MQL Minimum Quantity Lubrication system. They really are the perfect solution to controlled lubrication and chip control.

Thanks for the tip about using isopropyl with sewing machine oil, in stead of soluble coolant. What is your isopropyl to oil ratio?

I built a similar version using the same peristaltic pump head (e-bay from China) driven by a small stepper motor and also used an airbrush compressor. See build log "Peristaltic Mist coolant pump" post 36 onward.  I run LinuxCNC which we all know is the beating heart of the commercial Pathpilot controller. I hacked the HAL file and added six lines of code to create a 'step gen' signal to drive the pump's stepper, which is controlled by an on/off button on the screen. I have been too lazy to add a relay to control the airbrush pump from another screen button.

I found I was forever knocking the peristaltic pump cover open with my sleeve. The fix was simple; saw off the overhanging end of door opening lever.


Cheers

Mike

Thank you Alex.
The air is my version of a fogbuster. But it was fiddly to get going and then adjsuted so I built an MQL system.
First pic is of my fogbuster head, the others are of the MinimumQuantityLubrication I implemented. The output head for that one is from JBWorx Studio, it mounts using Locline. The code for the MQL is from https://github.com/hausen8/ColdEND32. EndCNC will not sell outside of EU so I made my own board. The bonus is that PathPilot will turn it on and off using gcode. It can run off an airbrush compressor at 15psi (as in the video) but it is now hooked to my larger compressor.

I  used to run soluable coolant but switched to isopropyl with sewing machine oil. Much cleaner.
