less pulleys, less drag, he put it on his saphire which is the same frame just differences might change results.

Ok cool. I was just curious. Iām going to built this one by the kit for right now and see how that goes. If I feel its lacking Ill sure check that out and see if it makes any difference. Its a 350x350x400 printer. Being able to have anything over 1000 accel will be a MASSIVE improvement over how it is stock LOL

this is my conversation with him yesterday

motors up front the belt only wraps around the pulley. When motors in back there is an extra idler to navigate to the motor pulley. This makes more drag. So in general less friction make less losses.ā
I am going to attempt his design and see what happens. If it fails, Iāll yell at him and tell him to fix it. LOL

Good deal. Let us know how it goes. Will be curious to see it
Well, more test fitting and more waiting on parts.

only half serious about my thoughts, but weāll call this a serious question.
What if instead of waiting for nuts which seem to need to be cast in the fires of Mordor or something with how they are taking, I decided to put heat inserts and loctite? It would certainly be cleaner appearance wise. But 5mm nuts are only available 2 at a time locallyā¦ and good luck finding Nyloc
I would advise against. The 3d parts arenāt designed for it so youād likely get a less than good bond and on top of that heated inserts are weaker as you donāt get the full strength of the PLA.
Can I ask where you are trying to get the nylons from?
Iāve looked at Lowes home depot and ace. I ordered them on Amazon because i canāt find them but they should be here today supposedly.
I was just thinking outside the box and being impatient.

Iām really shocked they didnāt have a bunch. I remember needing more as I used some for other projects and my ace had hundreds on a little bin. Had to buy individually so Amazon was cheaper per unit but I could get it done.
This was 90% of my build. It took me about a year to build mine. Most of that time was spent procrastinating cleaning the garage good enough to do it. Then once I decided to do it I didnāt want to wait 5 minutes before it was done

nobody feels good today in my house. Iām just watching my printer print off parts (for my printer ironically enough) while laying in bed.

These winter colds have been brutal in our house. I had my favorite pond hockey tournament this weekend. The Dr. told me I couldnāt go, so my wife played instead and I had to stay with the kids. Imt ready to be done with this crud.
My daughter is a tutor at the ymca after school program. She works with all the little germ ridden, snot nosed, crotch goblins. We get all of it when she comes home. Seems like this one was just a day of bleh and some time on the can. Everyone was back up and at it this morning.
Todayās updateā¦ no progress made. Amazon canceled my order and issued a refund. Would have been nice to know that. Iām building robots to do my bidding. Geared pullies are important. Grrrrrr
Did work on the printer upgrade a bit. Still waiting on parts for that too.
And progress is being made on the fire place makeover.

so Iām waiting on parts still, but have been reading re-reading and reading the Assembly Instructions tabs on the website. And Iām trying to wrap my brain around how to use my existing 4x8 bench.
what Im thinking is that if I printed the two rail rollers in mirror, I might be able to mover the y rail outside the plates. It wouldnt be a HUGE saver of space, weāre only talking an inch or so.
But my brain then went to "is the rail the limiting factor or does the core touch long before the rail becomes an issue. Thats where the end stop is so that makes sense.
Then I got to thinking right plate vs left plate for the y rail. If it the rail and dust boot get into conflict, or if that could buy that inch just by swapping sides.
Core touches long before the rail becomes an issue.
endstop is on the opposite side
I donāt think there is any extra room to be had from how its currently set up. With your table being 4 wide you will just have to build it a little bit narrower to fit the confines of the table. Or throw a new top on the table thatās a few inches wider to get to that full 4ā wide cutting area. One thing I will say is if you are going for the full 4ā run the calculator at 4ā 2" or so. Always good to be able to get just outside of what you want to be able to cut.
just meant that its on the core. but yes.
or back to the removable wings I mentioned earlier. like so V
this is silly. I might set it on that bench, but I wouldnt even get enough cut volume to make my own struts. Tablesaw/assembly table, or new dedicated table are still my best options. Not worth cutting the belts and rail for 32" of bench which without doing the math means less than 2 feet of travel. And that leaves room for Primo on the other bench 
If the table is 8ā long and only 32" wide then you would have more than enough length to cut any strut you want. Cut it along the Y axis not the X axis, Unless Iām missing something. if the boards you are wanting to slab are less than 26" or so then 32" would work. Idk the actual dimension you would end up with there without looking at the calculator but you could easily make that work. Then when you want to make it wider later it will just be some new EMT pipe and new struts.
That original idea was to make the x full 49" cut size so I could swap it onto the bigger table to get the full Y length, but use it as a stubby Y out of my way. 49" X Cut, is roughly 62" (depending on plates and such) So with that sitting on my more traditional sized garage bench, I could cut roughly 49x and 22y. But then if I swapped it to the bigger assembly table with added wings, I could cut full MDF.
That was the thought process anyway
