Second Build... Voron Switchwire

[Penatr8tor]

Building a bed slinger this time around. Kit is in transit. I went with Frombot3D, they did me right with my 2.4R2 build so I'm going with them again. Would have like to try the LDO kit but price and availability turned me away. I guess I will see if the savings ends up being worth it or not.

So far I'm printing parts. Base parts are Prusament Galaxy Black ASA, Accent parts will be FilamentOne ASA Sky Blue.

[smirk]

Looking forward to seeing how it goes!

[Penatr8tor]

The parts count grows. I'm really liking how the blue parts are turning out. My Stealthburner test build went together nicely. I got rid of the ols CW2 Beta 0 parts and replaced them with the latest revision from Github (The "Are We There Yet Update"). I just checked on my Formbot3D order... It's left the shipper and is enroute to the US. Fingers crossed the wait isn't too long.

Since my kit doesn't come with a wiring harness... I'm going to have to make my own, So I invested $50 in a new P-Touch label printer and bought a couple cartridges with shrink tube to label my wires. I love this thing. No more cheesy tape flags.

Wished I had one of those as I am doing the wiring on the Voron 2.4 now and had to use a marker pen to identify which wire goes where - only so many coloured wires. Going to have a look on amazon now

For next time.

Here's what I bought...

Printer https://www.amazon.com/dp/B00LV8QI9M?psc=1&ref=ppx_yo2ov_dt_b_product_details

Shrink Tube Tape https://www.amazon.com/dp/B097SJV2CR?psc=1&ref=ppx_yo2ov_dt_b_product_details

I went with the smallest tape size, 5.8mm.

[smirk]

Thanks, I was wondering which model you'd bought.

[claudermilk]

Thanks for showing which P-Touch. I don't know why my searches never turned that one up, all I was getting was the multi-hundred-dollar models. I have a borrowed one that I used for my build, but I'll have to return it soon.

[Penatr8tor]

You're welcome. I had to do quite a bit of searching around myself actually. The unit works perfectly with the tape and also has a wall wart too. The tape size kind of threw me off a little as there's no diameter mentioned in the description... only that the tape is 5.8mm wide when flat. I tried pushing a piece of tube over a brass rod to see what the maximum dia. wire I could go over. It fits easily over a 3mm rod but 4mm is too big. 3.5mm dia is max with the 5.8 wide tape. I haven't tried anything larger but I don't think I'll need to go larger for a printer build.

Thanks for this. Ordered and arriving next week here downunder. Tried local shops for tape but none in stock.

[Penatr8tor]

Frame assembled, Check!

Z Axis rails lubed and assembled, Check!

What I learned...

My 2.4 prints awesome parts LOL. The MGN12 alignment parts fit both the rail and extrusion nice and snug providing perfect alignment with zero hassles.

I bought some 1,2,3 blocks and a couple nice precision steel rules for my previous 2.4 build. These were extremely handy with the SW build. When I needed extrusions to be at given distance... Say 90mm from the end... I would clamp the rulers in place at 90mm and the thickness of the rule was thick enough to act as an endstop for the extrusion I was mounting. This trick of clamping the ruler in place at the right dimension saved me a ton of fiddling around. I placed a 123 block in the corner and tightened things down. Couldn't have gone better IMO.

Thanks for the tip. My next build is the Switchwire and have learned quite a few things through following your build. Looks excellent so far.

[Penatr8tor]

Making progress, just taking my time, enjoying the build process. 

So... This is what I really love about this process... I lube up the Y axis rail and get ready to install it and... darn, no 20x20 alignment blocks. No problem, I'll just print a couple. 15 min's later... I pop them off the bed of my 2.4 and... they're perfect. Absolutely love it!

Back to the build. Got the Y axis stepper and idler mounted. The coroplast deck panels are installed (loosely until I take off the protective sheet and secure them later in the build). I also soldered the leads for the Y Endstop switch and installed it onto the Y Belt Holder.

I also printed my first label/s for the Y Endstop and shrunk one of them onto the switch side. That was fun. I'm such a geek LOL.

[Penatr8tor]

Y axis belt is on, finally... What a pain. The Formbot supplied belt was literally the exact length. I mean no extra. I had to unscrew the front idler, loop the belt around the pulley and stretch it to get it in place. But, Hey... That's just part of the process.

I also installed the bed base, Y axis drag chain mounts and front skirts.

It's starting to look like a printer.

[Penatr8tor]

Got a chance to do some more work on the Switchwire build...

Got the X gantry installed along with the X carriage, XZ motors and belts. Going with a klicky probe right from the get go. And I successfully printed what's probably the longest part I've ever printed first time around so I call that a win LOL.

Got my klicky probe robot arm printed assembled and mounted. I'm looking forward to getting this up and running, should be fun.

[Penatr8tor]

Time to resurrect this build...

After dusting off the lint I'm back on the Switchwire. I'm really looking forward to finishing this thing. I'm still going with the klicky probe since the SW is not TAP compatible. I am also going to stick with the RC servo klicky arm, it's just too cool not to have it.

Before I left off and the reason why this project got shelved was that I had the daunting task of wiring everything from scratch. The Formbot kit I bought didn't come with a wiring harness like the 2.4 kit I got from them, it only came with a large coil of green wire. After a while I started searching around for wire kits that had multi-colored insulation to help with organizing. I ended up on Aliexpress and that's when the light bulb lit up... Why not see if there's a harness for sale. Bam! I found a harness and ordered it.

So here we go! On with the build. 

 

Test fitting the CW2 extruder. I'm using a Hartk 2 pc toolhead PCB. 8 pin connector interface to the fan/led pcb in the front cowl makes the install super clean.

 

That's literally it. 2 fans, LED's, Hotend heater and thermistor, stepper motor, x endstop and klicky probe. 8 connections in total and that's all you see. Love it!

 

Nice and tidy. Very pro looking. 

 

 

 

 

[Penatr8tor]

Moving on to wiring.

 

Blurolls Switchwire harness from Aliexpress.

 

Harness installed and routed thru drag chains.

 

A lot of extra wire. WOW! This harness is for both/either a Switchwire and Trident so I'm assuming that's why it's so long for the Switchwire.

 

Harness terminations. Most of the connectors worked, I had to swap out a couple JST connectors but no big deal.

 

Mains wiring.

 

Making progress.

 

Finally got the bulk of the wiring done and routed. Adding cable raceways made all the difference. I printed up a WAGO connector mount and created a 5V and Ground WAGOS for the Pi, Harness 5V and RC Servo.

Next, Install bed and wire up the bed thermistor, heater and Y-Endstop.

 

 

[mvdveer]

I love those ready to go harnesses. The only issue with the ones I ordered before is that they all seem to be for a 350 build and needs shortening. (Or a place to hide the loops) First world problems hey. Looking good.

[Penatr8tor]

@mvdveer Thanks, Yeah it took a good amount of stuffing to get everything into the raceway. I installed some keystone jacks for USB and ethernet into the rear of the chassis and was even able to get the the slack from those two cables stuffed in as well. I had to order some longer ribbon cables as the ones that came with the display are too short. At first the harness threw me for a loop when I saw that most of the connections to the controller from the harness had only 1 lead. I was like... Where's all the ground and power wires and then I realized that the toolhead PCB was taking care of those things because it has it's own +5v, +24v and Gnd wires going to it.

So yeah, Print Bed and a few wires and then comes the scary part. LOL

Burned the midnight oil last night to finish up the wiring. Today is load klipper / mainsail and get things up and running. 

I could have used another 6" of bed heater and thermistor wire. I didn't want to splice but it sure would have looked better than the somewhat taught diagonal run to the controller board. From a routing standpoint... there's just enough slack to not affect performance but no enough to make it look really nice. Can't have everything LOL.

 

Looking clean. I like the way the blue / black color scheme turned out.

Where did you acquire the exp1/exp2 breakout board? I also ran into display cable to short. I ordered a split cable from Ali for the SKR mini v2 but they look short as well.  I may just have to wire one myself.

Build looks great!

Thanks for the kind words... Glad to see another Switchwire builder here on Team FDM.

The breakout PCB I got from Etsy I believe as well as the 2pc Hartk SB PCBs. SKR Mini E3 Screen Adapter

I ordered the longer display ribbon cables from Amazon. Amazon ribbon cables

@Razor1666 Are you using a toolhead PCB with harness?

[mvdveer]

Like the color schem - looks great. Neat wiring, had to search for that extra 6" of wiring you were after. But then we always want more

Good stuff that midnight oil, it does look a nice clean build with good wiring  (I know you'll realy have a new heated bed with longer cable on order ).
