Voron Replicator 2!

  It's been a minute since I had some workshop time. Summer with two little kids is a hoot! 

 I'm back on the Frankenstein build. I had at one point a scaled up V0 Z axis. The printed parts had a good bit of flex with the large bed. But the real issue was how to tie the vertical extrusion to the frame. It was causing interference issue with the carriage and and rear mounted probe.

So I switch gears and printed the Trident Z axis and it works much much better! 

I have an SKR 3 EZ board on hand for the build which is now short stepper drivers. So I took a stab at using a 3 screw belt driven modification. I may need revise the design but it works well for now 

I also dropped the electronics lower to clear the belt and keep it hidden from the main print volume.

I promise I'll get back to wiring soon.

Worst case scenario. I swap the main board and drive 3x motors instead of 1.

Quick update. After a bit of playing electronics Tetris I have a layout that works well with all the connections, SD cards and USB ports. There is room for a wire comb as well.

I reprinted my motor mounts with an access hole for the 40 tooth pulley set screw. This allows you to rough level the gantry without removing the nut.

I'm much happier with this print. I aimed for the flattest part of my build plate and now the screw alignment is spot on. 

Up next cut up some cardboard panels to test fit and firm up the tensioner.PXL_20231020_165621416.thumb.jpg.82ec485d3b6f46a47161fab72e54ebf6.jpg

Ok so things are getting dangerous now..... A mechanical guy is doing wiring diagrams!!!! 

I am getting things ready to start connecting wires. Those who are well verse in the Angry Pixies please take a look at my connections so far. I think I got it right?

I am more of a mechanical guy as well but, looking over your diagram, everything looks right and I don't see any obvious ground loops.

I drew up a concept for a wave Share 7.9" display today while I ran off some calibration prints. It is a work in progress but it looks pretty cool! There allot of balls in the air but its coming together!

Mine Stealth Burner is on the machine after calibration. Let see if there is less fiddling with the fans this time👍

Two steps forward and one back today. I cut down my Y rails to 200mm and even got all fancy and side wheeled them on my surface grinder. But to find out a made a mistake and the the trident gantry has MGN 9 rails in Y and I have 12s !!!!!!

Oh well this is why Fusion 360 has direct modeling right? 

I am very happy with using the side of the wheel on my surface grinder. That was a first👍

Just reading through your build log, very impressed and a little awed.  Happen to have a small Home Shop of my own with a K.O. Lee 718 Surface Grinder and was wondering if you ever thought of mounting a cutting wheel on yours.  I have one setup for use on mine and it works great for cutting everything from extrusions, rails, prehardened stock and even the grooves in my gray cast lapping plates that I made for trying out the "3-plate method".  BTW your machine looks way cleaner than my old one.  Doing a complete teardown is in its future but I'm still able to easily hold a tenth or so tolerance so for my needs its easy to put off.  Love the work you're doing.

Stay safe.

Those WaveShare screens are great! I'm using one for a CyberDeck that I still need to finish. The aspect ratio looks perfect for your printer.

Good luck! I have had one blower that wouldn't spin up until I left a little extra slack in the wire.

Thanks for the kind words. Yeah I need to up my grinder game on the Harig and get a proper cut off wheel on it. I have been using my angle grinder with metabo disks to rough cut the rails. Then I side wheel them to size. I love that someone else on here also has a home machine shop! KO Lee is makes great machines. I have always wanted one of there cutter grinders to play with.

I got the screen rotated in on the Wave Share 7.9" (fully operational now! )

Following the instructions from the site below they neglected to mention that you have to "HDMI-0" and not HDMI-1 on the Pi 4 once I did that all was good. 

https://www.waveshare.com/wiki/7.9inch_HDMI_LCD

Three take aways:

Use HDMI Port 0

Don't edit Config.txt in regular note pad use Nano

Remember to plug in the touch screen USB not just the power (face-palm)

Some small but important victories today. I bored out the stepper housings so I could put a spacer in between the pulley and front bearing. I found that the set screws can follow the thread and really tighten down the pulley to the stepper body....not good.

I also updated my spacer block. The first version causing alignment issues with the small surface area of those pins. Now with a 3rd point of support it bolts up nice and straight.

I think I could easily integrate the spacer blocks and bearings into the main motor mount. But this will do for now.

Quick update. I have the wire raceways securely bolted into the printer and I recessed the adjustable nut into the left / right bed mount. I just need to add some holes for the rear wire exits and tidy up a few more items. Just one bite at a time I keep telling myself.

Progress today. After getting all the linear rails greased and lined up I finally got some wires installed! Everything on the high voltage side and 5V supply works. My screen powers on and no smoke👍.

I'll get the SKR3-EZ board wired up after dinner and get reading the manual.

Question for running the SSR on the bed do I have to do anything special on the board or configs vs just a regular 24v bed?

Just make sure you have a thermal fuse in place on the positive(Live) of the bed going to the SSR. No difference in the configs between 24V or 110V/220V

Quick update. My printer is fully powered. Currently digging into the config files. I need to figure out how to enable the SP_ON pin for my BTT relay. 

Also I picked up on the micro knippex wire strippers for the really small wire my larger auto stripper was have trouble with. It works fantastic! It's all about the right tool for the job.
