I'll put my two cents in here too. First I had to buy a 3A 5V supply because the 2A kept making the lightning bolt show up at the top right corner of the screen. Measured with a 6 digit meter it showed about 4.86V So make sure you have a decent 5V supply. I'd suggest at least 5A and not

Well, the portability is not a must, but the idea of having all the major hardware as compact as possible really tempts me to at least consider the idea. For the other machines I used mini ATX with one PCI express port to accommodate the Mesa board. For this project I'm inclined to use an Ethernet

Why does the control computer need to be portable, unless you are building a portable router and want the whole machine to be easy to move? As for Octoprint, I use a standard PC (an older i5 with about 8 GB RAM.) f In fact, the very same PC runs both LinuxCNC and Octoprint at the same time just

I have several RPI3's and RPI4's.  what I noticed (with the RPI4)  more memory is always better. There are  things they are good at, especially "light-weight" stuff, and other things they are not.   I use one as a datalogger, I tried RPI3 RPI4-1GB/4GB/8GB, and it has timing and temperature

Hello all and thanks again for all the feedback, Well, to clarify a little bit more this is what I have and I what I intend to do: I'm planning to use the router to cut just sheets of MDF and Melamine with compression toolbits mostly, and some drilling too, all carbide off course. I do have a 3

Hello guys, As some of you know, I'm finishing a CNC router and I'm about to purchase all the control hardware. I know Gene, John, and several people here are running LCNC on the PI with success but I would like to know how much of a pain in the ass is to get it running well with a 7i76E for

Hi Rob, I've used my ELS for all sorts of non-ELS projects. Especially since the original had a 3A 55V micro stepping driver on board. Or it could drive external motors. For the longest time it was the power feed for the knee on the mill driving a Gecko and a 1000 oz-in motor with 3:1

Hi John, With regards to the BBB I was running MK (wheezy) on using the PRU, which for my needs seemed to be ok, I didn't notice any graphics issues. The thing that turns me off MK is how it's split and so forth. The reason my interest has piqued is because I have a project on the go that
