Hi Timothy,
I second Gustavo’s reply. 2ftx2ft is a great size ESPECIALLY if you are making the low-rider as well. The biggest part you need to cut for the low-rider is just a tad over 12 inches long.
Just make sure that you download the Lowrider 2 files for the correct tube size and follow the instructions in the materials list of quantities to print. The old version files are not mixed in. You only have the required files to make the version 2.
I think that Michael from Teaching Tech’s method just illustrates that not having a cnc should not stop anyone from trying to make something as the plates could be made by hand IF you do not have access to a CNC, but machining them will always give superior accuracy as Gustavo says. Drilling holes accurately by hand that line up with the 3d printed parts could be an issue if not spot on, not just spacing but angle as well when drilling through thick material if not in a drill press, and you want accuracy for the end results to work properly. (experience talking here, I’ve got the T-shirt and the video. If something can go wrong…)
Some advice from my experience if I may.
Consider size. You have to live with your MPCNC and Low-Rider once they are made and they have to sit somewhere, pretty much permanently. I am talking real estate, space, It’s great when you have a job to do with them, but a pain when you are not using them and trying to use the workshop space for other things (also from experience, I have been living with my MPCNC for a year or two now and know that family (specifically wives!) do not have the same respect for your ‘toys’ as you do. Things WILL get dumped on them and break them. Luckily it will give you the excuse to rebuild them to the latest version. (More life experiences shared)
Also, for the MPCNC use the correct files for the size of tube. Buy the Pipe first. Another lesson I learned. Use a vernier to check the pipe size.
Check your router choice. This will dictate your tool holder which is a sizable print so you only want to do it once. Check the router will work on both the MPCNC and the Low-Rider as its a large expense to buy two. There are two main choices supported.
I build from what ever I could source locally (South Africa). With all the failed prints etc, I should have brought the kit from V1 Engineering. I don’t think I saved anything except the experience and knowing each part intimately… a few times. Do your sums and decide if you are really saving by sourcing parts yourself.
Electronics, I opted for Ramps and have been very happy with that choice but I see a lot of others who are less enchanted. I got a Rambo and had such issues with that so have gone back to Ramps & Marlin.
I would definitely start with the MPCNC (I love my MPCNC) It is just so well designed and documents and supported and if you take it step by step, you will be successful. That would be my advice from my experiences. The MPCNC was my first venture into making anything and the learning curve was well worth it. This forum is also invaluable for support from people who have already been through what you are going to go through.
Then you can try the MPCNC for laser, Plasma cutters, the options are endless.
The MPCNC will be your go-to machine for sure. Good luck and enjoy the experience.
