Yesterday to try and keep out of the heat I stayed inside and tried to get some work done on the CNC Mill. I have tested all of the steppers and everything looks good there. However the Pololu stepper drivers I have only have a fairly small heatsink on them. I am not exceeding the rating that is recommended with the supplied heatsink, but I am at the limit of what can be done there. So with that in mind, I would like a bit more headroom.
That was a good plan. Except for the fact that because I haven't done anything with this for months and months. I couldn't get machinekit to run at all. Then I tried a new, clean image to make sure that there wasn't a setting causing the problem. However then I ran into a problem with my HDMI to VGA adapter. Apparently the Beaglebone Black doesn't supply enough current over the HDMI port to run a passive adapter. So I either have to hook this up to the TV in the loungeroom, buy an active adapter or I can mod the passive adapter. I actually have all the parts I need to be able to regulate the 12V down to 5V needed and wire up the regulator. So I might end up doing that.
So keep an eye out for either a fan installation, or modding a passive HDMI to VGA adapter.
Actually I just remembered that I have a fan in one of my servers that is run from a molex connector for the disk drives. That means it runs from 5 or 12V DC and can be made to work here. Seeing as I am not using the servers anymore I might just re-purpose it for this.
