I'm interested in one of the delta arm models, like the Rostok, as I think they're cool.

Assembling the Y idler. Here is my first complaint... this step uses 3D printed parts- and the print quality was pretty poor on these two. I'll explain more when we get to the pics.

Parts.



These two slots are supposed to have nuts slid into them- but as you can see the right slot is warped. It took me a bunch of dinking around to carve it out big enough to get the nut to fit (both sides were too small and had to be carved out).





Finally got them in...



This nut went in fine, but the screw wasn't long enough to reach it so I had to drill out the other side.





Once I got it drilled out enough, take the screw out and install the bearings.



Attach the base. The instructions called for M5-8, but they wouldn't reach so I used M5-10.



Install the tensioner nut on the back. This hole had to be carved out too...



And the tensioner screw.



Easiest part- put it on the machine.



Time Spent on this step: 40 min. (should have been like 5...)
Total time so far: 6 hrs 30 min.

Fiddling and tweaking.

Spent some time adjusting things to get everything square and moving as freely as possible. The first order of business was to free up the x-axis- I made the mistake of tightening up the rails too soon. One of the little screws stripped out trying to loosen them, so I had to drill it out, slide the rail out, and replace it.





Once I had that fixed, I just slid the plate back and forth and slowly tightened the screws until they were all tight and the plate slid back and forth freely.

The z axis was similar. Loosened things, and slowly tightened them back up until it seems to move freely. The thing that seemed to make the biggest difference was to not tighten these busing blocks as tightly- they are plenty tight, just not gorilla tight.



The y-axis didn't need and adjusting- it moved very freely.

The last thing I did was fix the x idler- had to add a few washers. Here is the correct assembly.





And installed.



Also went over all of the nuts and bolts and checked and tightened anything I found loose.

Time Spent on this step: 1 hr.
Total time so far: 7 hrs. 30 min.

Finishing Touches.

Parts:



Install the pulleys. They have to be oriented a certain way to line up with the axis and idlers.

Y-axis:



X-axis:



Cut the belts.



Attach one end to the axis plate. Y axis:



Loop it over the pulley



And through the idler



And attach it back to the axis plate.



Obviously the extra belt needs trimmed off still...

Adjust the tension using the idler.



X-axis.











WOOT! Think I'm ready to hook up all the electronics!!!

Time Spent on this step: 30 min.
Total time so far: 8 hrs.

Update but no new pics. Spent some time routing wires and figuring out how to hook things up. When I was talking to the company about what electronics to get, they recommended I get the RUMBA contoller board. It looks like the mounting brackets supplied do not work for my style of board, so I'm going to have to make something up. Same for the power supply. Means it'll take a little longer but I feel like I'm reaaalllly close to firing it up and figuring out the software!

Time Spent on this step: 45 min.
Total time so far: 8 hrs. 45 min.

If you have 3D CAD to design the parts you need, I can build them for you on a Stratasys machine.

So I lied in the last post- here are a few pics.

Electronics bracket... not designed for my electronics.



Rubber feet.



Install one foot, then the bracket, then the other feet.





These should have all been installed while assembling the frame... The instructions have already been fixed to reflect that.

Time to finish up the Plastruder.

Parts.



Install and tighten the nozzle using the 2 lock nuts to hold the tube while tightening the nozzle, then remove the nuts.



Heater.



Mount.



This was kind of tricky. You can barely see the thermistor- it needs to be touching the nozzle and is held on by the "Kapton" tape.



Installed.



Insulation.





Had to install a few connectors, including soldering the teensy bits to the wire first.









Again, if you buy a plastruder, pay the extra $10 and have it pre assembled!

Installation.







Done.



As you can see I pulled the bed back off to run wires. Lots of them going all different directions. I'll have to mount the power supply and RUMBA board, then I can finalize the wire routing, plug everything in, and try it out.

Time Spent on this step: 1 hr.
Total time so far: 9 hrs. 45 min.

Got some bits made and installed. Battery died on my camera, so these were taken with my Ipad- sorry for the quality.

Made an adapter to fit the electronics board to the included mount.



Installed. It's spacered up with washers so the contacts on the back side don't ground out.



Made some temporary mounts for the power supply since mine are missing...





Turns out this piece doesn't need the t-nut, it holds itself in place with the little hook.



Which means, taking off the front plate like this was totally unnecessary.



Power supply and RUMBA board installed.





Spent some MORE time fiddling with axis trying to get them to run smoother and also running wires. Trying different things out as far as routing... still haven't settled on anything but I think I've got it figured out. I'm going to have to extend a few wires to reach the board...

Took some vids today too.



X-axis operation.



I did also run the wires from the power supply to the RUMBA board. Feel like I have a million little things to do still but I think I'm getting close. Was hoping to get more done in the time I spent on it today, but c'est la vie.

Time Spent on this step: 2 hrs.
Total time so far: 11 hrs. 45 min.

More wiring...

Had to lengthen some wires, add some ends, and route a few more pieces.





Put this cover thingy over the wires from the heated bed. No idea if that's what its for, but it looks good to me.



Got everything sorted out and routed where I think it is out of the way of moving parts.









SOOO CLOSE!



It MOVES!



Now time for software.

I made this earlier in the week on a commercial system. It's a "holster" for my snow thrower shear pins.


This is the system making it. You can see how it makes the outer profile, then fills the the inside.


It's more or less like watching paint dry. This part took 26 minutes to build and material was about a dollar.

Yeah, we have a variety of systems at work that print in starch , plastics, and metals with powder, liquid, and spooled materials. I want to see HIM make something with THIS system. :

Tell me about it! I'm itching to make a print, but I have a ways to go. Turns out the first item I need to download is currently unavailable because the website is down. .

This is cool stuff, cant wait to see something made myself. This could have possibilities for the custom bike builder?
