I found a good deal for a 5' x 12' Multicam CNC router on Ebay. I have spent the last two weeks completely gutting it and retrofitting it. It had stepper motors and was pretty slow and noisy. I replaced the drive system with clearpath servo motors controlled by UCCNC software with the UC300ETH controller. Here is a quick video of the first test using g-code and air cutting some circles. So far so good. I still have a few things to finish on it like the homing function and spindle control. This video shows how much faster and quieter it is now. I will be posting more on this as I get toward the finish line.

That's pretty sweet.

@ger21 - This is the machine I purchased your 2017 screenset for. I wanted to be able to do the tool height setting easily as the machine came with the height setter sensor plate. I will keep you posted when I get to that point. This is my 7th router and my first using UCCNC and I am extremely impressed so far. I'm using the M45 motherboard with the UC300ETH. I wanted to ask you a question concerning homing, as this is my next step. The home sensors on the x and y axis are pretty far away from the actual "start corner" of the table surface. Is there a way when homing to make x go a certain distance away from the home, set that to zero, and then make y go a certain distance away from its home sensor and define that as zero. As it stands right now, when the homing is done, the machine will have to be jogged the the start corner of the table and then zeroed from there. Any suggestions for this? Thanks for your work!

In the 2017 screenset, Axis setup, by the Homing speed, is Machine Zero Offset, which is the position of the home switch.
The quick answer is to set your home switch positions, like X=96, Y= 48, and set a Park position to 0,0 in Machine coordinates.
Then Home, and Park. You could combine the functions be creating a macro, and editing the button function in the screen editor.
That would be one button click, instead of two.

@ger21, excuse me if my question sounds weird... Let's say the location of the area where I actually want to set to be 0,0 is "forward" of the home sensors. So from that point being 0,0 - my home sensors would be negative of that point, let's say the x home sensor would be -2" and y home would be -1.5" from the actual place I want to call 0,0. Will that be doable, or do I have to think differently here? So basically, when the machine hits the sensors and finds home, the actual start location of where I want 0,0 to be is + 2" from the x home sensor and + 1.5" from my y home sensor. That location needs to be 0,0. Sorry if my description is awkward. Maybe in the video you can see where my y axis (the one going left to right on the gantry in this case) home sensor is way to the right of where the actual area is where I can cut material. Its that little round thing toward the right of the gantry about 6 or so inches in from the right.

[ger21]

Yes. Just enter -2 for X, and -1.5 for Y in the Machine Zero Offset. Then set your Park for 0,0, and check Machine Coordinates for the Park position. Then click Home, and then Park when homing is done.

Perfect! Thanks Gerry!!! I will try all this once I figure out why none of my inputs are working. I posted this in a different thread...
