Check out this beautiful build and control action!
Very awesome build! Really like to see the Pi implemented, nice job
Nice build and video.
Are you concerned about airflow inside the SS case?
Can’t tell if there are fans in there or not.
@cmcgrath5035 not our build sir. One of our customers put this together.
@Brandon_Satterfield I built this. You can get the bulk of the parts from SMW3D.com - I actually had the stainless steel panel in my garage. No I am not worried about heat because there isn’t a lot of heat load there. There are also 3 fans AFAIK, 1 in each power supply for total of 2 and these are often put inside of these panels. The last fan is jerry rigged to a power supply to direct onto the tinyg board. Again, there isn’t a huge amount of power here.
A bit about my background - I come from the Controls Engineering realm of Industrial Automation and Controls. So I have seen drives that power 1/2 horse electric motors in a cabinet not much bigger than this inside of rooms that reach ~120degF. Another good example would be like a lathe. A lathe would have a VFD inside of a cabinet about this size putting a lot more watts out than these two power supplies could ever possible transfer.
But if you are asking me if I did the power consumption and heat dissipation calculations… no I am shooting from the hip on this one.
@TemperedEnterprises I’ll have to go check them out…:-).
It is a great looking build! Really love the rPi interface.
Want to thank you too, you called out Smw3D, OpenBuilds and Chilipeppr in the video, know @jlauer (maker of Chilipeppr) reposted I wouldn’t be surprised if you get flooded with “how’d you do that and where’s the code?” Know @Mark_Carew_OpenBuild gave you props too, he is the original designer of the OX that has been a perfect intro for so many of us to the realm of CNC.
Thanks again, great build and great share, look forward to seeing the awesome things you build with these cool tools!
@TemperedEnterprises I could not see the tinyG fan, that is usually adequate.
Rest state dissipation of tinyG is low.
Running a long Gcode job with 4 NEMA23s will dump a lot of heat into the tinyG PCB via the driver heat slug packages.
Give them a finger test after a long job. Drivers are thermally protected, individually, so overheating a driver will likely ruin a job. Only experimentation will tell what your true range of operation is.
Nice looking build, by the way
@cmcgrath5035 yeah there is more to come…
