Well, it took some major work but I got my GRBLDuino Mega working while stacked on top of a Re-Arm board. The wiring is still a mess and I need to mount a few things but it works I had not expected that the Re-Arm board would not have all of the arduino header pins populated. Of course at least 5 of...

After a full day trying to get grbl or marlin to support everything I need I decided to dive into Smmthieware. Because an Arduino will not support Smoothieware firmware I had to swap everything to a BigTreeTech skr 1.3 that I had laying around. Within an hour I had a known good OpenPNP configuration...

I have 5 axis grbl running fine, however it does not really play well output wise. I can only control one spindle related output and one coolant related pin, the m9 or m5 command will kill all pins related to either. This required having a second arduino controlling the multitude relays needed I tri...

I have tuned out some of the motion a bit more. I now have X,Y, Z , and rotation on 2 heads. I also have written code onto an arduino to control a relay board that will activate things such as camera lighting, vacuum solenoids, blow off solenoids and other miscellaneous things. I have also set up a ...

I have not managed to rework grbl yet, but I do have 4 axis coordinated motion. X,Y,Z and A are all moving under the control of OpenPNP. OpenPNP is running via simulated camera input, adding cameras is probably up soon. Once I have cameras set up I can use some component tape to test things as I mak...

My latest project will be to build a Pick-and-place machine based on the IndexPNP design by Stephen Hawes (https://github.com/sphawes/index). I will however be running it on 5/6 axis GRBL instead of Marlin. I am currently printing parts and gathering parts. While I wait for all of the hardware to ar...

It's coming along. At a stop for a bit since it is in a usable state now. My wife wants to make some signs for her work with it. They may take 20 hrs to do with a 5w diode, but they will get done. Then on to buying another k40 to rob the co2 laser components

Well, after a rather long break on this project, I'm back on it. I changed my mind on the kinematics and decided to go back to the traditional cartesian xy, mostly because the belts for corexy were so long that stretch was going to be a problem keeping the laser path true. After getting the 3d print...

Made a little progress the past week or so. Made some pulley brackets, and motor mounts. Laid out the belting and started getting my head around where what will be fitting. Getting closer to hooking up control and seeing if it moves properly https://uploads.tapatalk-cdn.com/20190327/802124e116ff0d72...

Looks good. I usually fly by the seat of my pants when building things, but it helps to at least have a rough plan. I started my journey into cnc work with a mpcnc, it's a good gateway machine. Now I have a 6k lb 7.5hp machininng center in my garage that I use for prototyping miscellaneous projects ...
