@@sbirdranch i agree your videos are great. I am curious if you have a parts list developed. I have tried to find a few of the parts you used but have not been able to. For example the motor standoffs did you manufacture these on your own. I have looked all over for a shouldered threaded standoff/spacer to no avail. Suggestion on where to find these?

Glad your back at it, I've been waiting to see the next step of your build, this is definitely a project I will tackle in the New Year. Right now I'm re-organizing my shop (Making it Ship-Shape) for the coming year, it needs to be clean, neat and presentable so I shoot my videos and not show the clutter i've accumulated over the last 10+ years.. I wish you and yours have a Happy Prosperous New Year.
I love shop organization. I'm doing it now in another area. Some of my best projects are for the shop....come to think of it, most of my projects are for the shop. ~P
I built my pole barn ~ 9 years ago mostly for storage and occasional work, about 5 yrs ago I insulated & heated it to make it a nice workspace with some storage, last summer I decided that It would be a perfect working studio for my new channel but that would require a complete rethink, fortunately, I managed to convince my girls to help me clean and reorganize it; It's going to be a busy winter...
Excellent commentary, especially the 'no I did not drill into the parallel'; sure looked like yo would. Great watching the build, and for the mechanical of us out here nice to NOT watch you true the ends of plates in the mill, or watch tapping; Keeps it moving along. Looks like and excellent build design. When I worked for a 3-D printer company I ran into the pressed on flanges on the timing gears, also. Looking forward to more progress :-)
Thanks for the feedback. I am trying out the `narrated` style of video. My wife says they are my better ones. I try and keep the repetitive tasks to a minimum but be patient...not everyone is a `mech. In my next video I tap holes 3 different ways just so people understand that you don't need a fixture to tap a decent hole.....also in this next video....i do hit a parralel. Damn It! :) ~P
Build is looking nice inspiring very instructional in your explanations that is really helpful as a viewer. The two of us think maybe we can build something we need or just would like to build one of for our shop. You drilled into your parallel I remember cutting into our vise jaw on the CNC mill it was a bad (more made) day for us. We are surprised as well did not see that coming who made a pulley like that anyways? We best take a look around our own shop to see if we have any of these pulleys.
I was just looking at your channel and Instagram. I will sub and follow. You mention having a cnc and I thought as much based on one of your IG pictures. I was thinking with your (both of you) skills you could male a nice 2` square size router for PCB routing and engraving. Now for the side note. I too am a native of So. Cal. Only I escaped LA to the countryside of SW Ohio. ~P

Nice work looks like your really making some good progress and thanks for the update, after months of searching different online stores I found quite a plethora of parts on fasttech (NO AFFILIATION) such as a 2GT Timing Belt and its 6mmx4500mm for $7.52 what is your view on this specific belt ? it seems like a steal for X and Y axis compared to ball screw, screw, and rack and pinion linear motion. I have no personal experience with timing belts but have been a little concerned about possible belt slop or back lash when the weather fluctuates hot seasons to cold and vice versa, any input would be greatly appreciated. I do know for sure I will be going with a 4'x8' table style cnc and primarily be cutting 3-8mm acrylic.
Did you end up using that belt? I'm doing the belt reaserch now, from what I've found GT2 is the way to go, but there are so many parameters and materials etc. to consider that I'm getting confused.
Maybe I missed it in another video, but is there a reason you switched from linear rails and bull screws (on the cnc router) to belt drive? I understand this solution is cheaper, but other than that, is there a compromise of accuracy here, or?
building a CNC plasma using ball screws is a very bad idea it's a nasty environment which will increase the wear and affect the movements of the screws - in my opinion you have to choose one of 3 - rack and pinion drive which is the common used solution - belt drive - and chain drive . chain is not often used but still good solution. remember that plasma or laser cutting doesn't need so much force because there is no reaction forces from the cutting operations compared to any other operation like milling. so these solutions are very accepted .
Would this design work for a CNC Router? I noticed your Router design is much sturdier and with more precise rails. But this one is probably cheaper and simpler to build. I'm looking for the best design (both in money and difficulty) for my first CNC Router. Thanks
It won't work for anything with side pressure on a spindle like a router. A plasma has no side thrust and also isn't as precise a cut as a router so you can do with simpler rails.
Are those belts fiber or steel reinforced? If not look into that. I use the same kind of belt on my Delta. I use the glass fiber version. They settle after 50-60 hours of use and need tensioning again.
They are fiber. I'm not sure I like the size I selected. They seem a little anemic. Time will tell. I will watch the tension and keep them adjusted. Thanks. ~P
afaiu fiber is preferable for open belts because it bonds better to the rubber so it doesn't tear out at the clamping. It also makes sense to double up the belt in the clamp, gt2 meshes with it self
Do you recommend any specific place to buy the GT2 belt? I'm having a hard time at selecting one at SDP (www.sdp-si.com/), they have so many variations and parameters...
How much does your gantry weight and how fast are you driving it? I have trouble imaging those belts / fasteners not having slack. I want to drive a 10 kg load at 1 m/s with 0.1 mm accuracy. Is this realistic with belts?
I have to do a little conversion..... 10kg = 22lbs, 1m/s = 2362.2 IPM. .1mm=~.003' I can't imagine that kind of travel speed. But that isn't your question. My gantry probably weighs about the same, maybe a little more. Lets say 35lbs/15kg. I had some of the same concern, but figured I could always change it later if necessary. So far it has not proven to be an issue. There are steel threads in the belts, so they get tight...very tight if you want and have very little stretch over the 4'/1.8m length of mine. I do not notice any spring on direction change either. Keep in mind this is a plasma so there is no radial load on the cutter. I have tuned acceleration down some so there isn't any hard snaps or movements. The machine is on casters and with acceleration turned up too far I can slosh the water bed pretty bad, even with all casters locked for rotation and pivot. As for accuracy, they will hold it. When it comes to the belts, accuracy would be in back lash and by having significant contact with the drive cog, there is none at that location. I have a little lash in other places but holding .1mm is pretty easy. Again, this is plasma so .1mm is pretty tight to expect from the cutter. Good luck and I hope this helped. ~P
This is one of those videos that deserves WAY more views that it actually has. Very nice job.
Thanks. Very kind. P-
