I was planning on modifying the bracket to accept the brass nut that comes with my TR8 rod, but there's a screw/nut library on Thingiverse that would enable you to print a nut for any diameter / starts. Dalvlexa 3D printed Screw Library by Syvwlch

These nuts here are for 2 common Acme multistart leadscrew sizes: ACME 8mm Tr8*8-2p + Tr8*4-2p leadscrew nut / 4 and 2 start/ by silyavski.

 

Hello Keith,

I love your design and i want to build one but my need is to have a 40cm x 40cm x 40cm print volume.....So do i need to multiply the size by 2 and using the same stepper motor and electronics or do you know a model like yours with the build volume that i want ??

 

You are awesome . thank you very much

 

True Up Glide completed and bloomin wonderful it is too!!

 

Great looking build! I think I might build one with an extended Y using a 300x200mm heat bed! Also might redesign the glide bodies and print them in nylon. Tap the m8 screw nut into the body and maybe design one of the two bushings into the body as well.

Keith, did you recently say you weren't sold on using full steps on the Z yet? I thought this was crucial part of your design to eliminate micro stepping?

 

Where are you at with the "kit" you are working on?

 

Great, looking forward to seeing it come together.

Now back to licking my wounds.... My furnace quit a week ago and after an emergency repair to get it going, it was also discovered that the heat exchanger was cracked, so a new furnace was the answer. To add to the misery, I figured I might as well replace the air conditioner while we were at it. 2 hit and run damages on my car in a parking lot and new prescription drugs for the Mrs. not covered by our insurance and my financials are bleeding red! <sigh>

Oh well, at least I have the parts for the OneZ that STILL is not finished...... gah!

 

Better you than me, I'd probably choke on it!

 

Keith, I just bought the 8mm threaded rod from my hardware store, They are 8mm x 1mm pitch, If it is 1:1, shouldn't I use the same pulley on each end?
The other 8mm I see listed as "coarse" and is 1:1.25 which makes the 20 tooth / 16 tooth make sense.

 

Not yet, but the steel nuts on my Mendel Max XL have never been an issue.
I am looking to print some nylon and us the treaded shafts as taps, if I can't find premade nuts.
For some reason, the hardware stores around here don't seem to have the1.025 pitch.

 

Any chance the 3 long parts have been remodeled so they will print on most printers? They won't print on a 2800 printable space Rostock V2 delta. If you have done this, can you please post the .stl's. It is holding up our TrueUp build. If you don't have them, I guess we will have to 2D the sketchup models and laser cut acrylc for them.
Piece across the front, with USB
Pieces underneath for PSU and controller

 

Thanks. I will split these and get them printing. I was going to do that, but didn't know if yours was going to have locking tabs or ??

 

Keith, any news on the kit? The Mrs. fell on top of the open door of the dishwasher today (there goes another $500)... I'm running out of funds!!!! <sob>

 

Sigh.... I've been looking at new dishwashers.... the Mrs. is fine, but $500 was overly optimistic. It's going to be more like $800 including taxes and an extended warranty. I don't normally buy extended warranties, but our current dishwasher blew an o-ring just past the 12 month mark. Whirlpool only sells the entire bottom pan including the motor if that o-ring fails, for a measly $480 + labour and taxes. Thankfully, there was a way to work around it.... This time, the bent door is going to make it a replace only sort of thing.

This kit you are planning on... is it a complete "everything you need is in the box" sort of kit, or is it just the basic plastic bits plus the extrusions or something like that?

And yes... there's always "one more thing" you'd like to fix.... Set a date and lock it in.... then, start working on 2.0 while shipping v 1.0. If you come up with something that absolutely should have been done in v 1.0, you could release an upgrade "kit" when you start shipping v2.0 to new customers.

 

" (Only God knows how many 3D printer kits never get finished or never print right when finished. Online forums indicate a high percentage.)"

Keith, you're not outside, peering through my basement window, are you?!?!?

 

I finished my build of the TrueUp Glide. The build went well, will be testing and doing prints this weekend.
It will get a wide range of filament thrown at it including some flexible filaments I've been wanting to use. Will be packing it up for the 8 hour drive to Goshen for the 2017 MRRF. ;-) I'll post pics of competed printer this weekend. Thanks for he help Keith.
