CNC Router and Plasma combo

I build a cnc router and plasma combination to save the space for one of them. I used steel pipes to build the frame and the gantry. For the most connections I had used screws to avoid that parts get crooked after welding and so I am able to adjust most of the parts.

Hi, yes I haven't shown my parts until now. There is one part missing I want to make an overview video about the machine but I haven't made it yet (there are so many things to do...).

I'm using an arduino with a shield for estlcam (software), 280Ncm motors, a 48v power supply, modul 1 rack and pinion and linear rails with 20mm (more in the next video I hope I will get it in the next weeks)

1.) I'm using Estlcam (really simple to leran for beginners). Thanks for the tip with MasterCam I will have a lookat it.
2.) I don't have a backlash compensation. I had everything aligned as good as possible and hoped for an acceptable result. And for me the results are good enough for now.
3.) I don't really now It's hard to say but maybe I would spend the money for ball screws to get a more precision (and also a much more quiet) machine if I would build it again.

By the way thank you very much for your comment!

Thanks for getting back with the additional information, Sam. I watched all your videos again and gained better understanding of your build and more confidence in taking on such a project. I appreciate the time you spent in documentation the build and then sharing it with us. The only change I am considering is bending the sides of the sheet metal pan and welding only the corners, saving all that welding. Thanks for the specs on the motors that really helps.

Yes it's much better to bend the sides of the water pan, but I don't have the possibilities to do that, so I welded it. Next time I would only make a few welding points and seal the pan with silicone than the sheet metal would not be so crooked.
