Pondering Phase...Printer almost complete, I need to print a part cooler but don't want to print just one part...pondering for days, when I decided on a 90x90x20 interface plate to raise & mount the bed at the required height...though that was going to triple the print time...then I chopped it down to 50mm wide...before realizing I didnt even need to print anything & could do it better with metal parts, which just so happened to be 20mm high as needed. So far there's 10 or 11 plastic parts, I could have made it just six, or 4 & 2 sheet metal parts, it pay's to ponder longer.


Finally got around to printing the fan duct, the blue tape didnt look good on the pics...I had left holes for one in the future but decided to not use them for this, not sure why I didnt extend it a little further, but it covers what it needs to. Also printed another part cooler duct for the current build, though not put it on yet.

Printing Printer Parts on hold while I plug a few other holes in the shooting armory, manual focus is a pain, dual focus a bigger pain, & close focus with anamorphics another challenge.

Cinelux closest focus is apparently 3 meters and the smaller Ultrastar about 1.2m, I have two Cinelux anamorphics but one is set at infinity and needs to be fixed there, as I I have the VFD focuser that goes on the end of the chain(not pictured), changing focus all the time is not ideal, so I thought I'd setup the other as a closer focus unit, so it's set at it's minimum(not sure if there was more turns available didnt want to break any glass). Using the cheap Tamron 77mm close-up 0.5 diopter get's a more usable range. I found a smaller stronger close up lens and fitted that on the Ultrastar so with that I can go closer again, about 0.75m-1m.

Also needed another mount for the IPIX lens

2021 Now I can release the secret of how to make a kilo of PLA last a year, whilst being locked in a room with only 3D Printers for company. I think I still have half a roll, the race is on to see if I can finish it by 2022. Though if I want to complete the latest gizmo I need to print a couple of 110mm diameter parts which should finish the roll off...so because I hate the long prints, i'll focus on some smaller components for my linear focus assist gizmo, 2 new products for the film maker, can I make this product a reality before it becomes a craze? (there's at least 3 different forks).

I've been thinking about making a mini actuator for many years finally got round to doing it, though it's much cheaper with a standard hex bolt(needs less components) i've not seen any in the camera gear yet, maybe they didnt see a need, but I have a few places to use it. Funny how far you can stretch 20g's of stuff....

Not many parts arriving in the post these days, but when they do it's fun trying to figure out where to use it, spotted a new useful plate,
though they didnt list the dimensions so wasnt exactly sure what i'd do with it, decided to switch out a rather large overkill plate for this new one.
The small cantilever printer seemed a good fit, but now I need to alter the belt path from before, which means a new idler for the 2020 & new cart/hotend holder and new Z nut holder, lucky I already had a similar one printed, finding the orig' project would have been more time consuming than importing the old stl & remaking another to fit better. I could just print a one piece item and do away with the rod holder part, thinking about some POM nuts....or if the profile had of been a tad longer i'd have mounted one of the plastic z nuts on the side of the profile. If I made a backing plate for Z and then placed the new part on top things to neaten things up??? While designing a new hotend holder I've been looking at getting something else that fits with the design better, I really like the Biqu all metal (stainless) vertical heater hotend, cheap enough at the moment...but i'm sure that besides the mounting problem there may be other problems with it, or with me and more exotic materials, and by the time it is mounted and covered in fans, it negates the reason for buying it...I want to see it looking sexy. Not many others at a decent price to choose from so may just keep the v6. China seems to be going premium prices these days...congratulations to our wonderful governments for helping facilitate this. Keeping printed parts to a minimum on this machine, so rather than print an idler for the 2020 or using the method I used on another machine,, I just bought a complete tensioner for £6 almost the same price as the parts for my other method, and much neater to boot. Only 3 printed parts in this machine if I swap out the printed idler for a metal solution...and I just realized dont even need an idler plate to do it, the 45 profile that makes the frame will hold an 8mm stud.

Cheers Mike here's a couple with the lights on.

Printer decided to play space invaders while waiting for the cowl to finish.
Idler for X still on the boat, still undecided on new hotend parts, wondering if doing away with the 3rd Z bearing would be too detrimental, might look better with slight rearrangement, ie one metal bearing housing and the other by the motor 3d printed but with a longer bearing, will get a shorter shaft for the bed idler at some point and if I can find the 8mm flange bearings i'll slip them in.
I wish there was a little more choice on 40mm fans, the standard 40mm has some nice contours that this LED one doesnt have or can't be seen, i'd prefer the outer part black & just the blades glowing some patterns would be cool.....I can wait. I think the slits on the side mount part cooling fans are probably too wide at 4mm was going to go thinner, maybe next time, I doubt i'll be needing them anyway just put them there for a little flexibility in the future. Maybe move filament roll of top of Z, though I can hit the column quite had without any noticeable movement

Tempted to get a little skr board to neaten things up a little more compared to a bulky ramps sandwich.

Decided to buy this sexy stainless hotend(£14) Some Italian trying it on on ebay wanting £46 for this, even though I could see alternate, newer, better options, even though it might bring no end of issues? Mounting a fan & duct not ideal, also the 24v heater I have doesnt fit due to the sleeving over the joins and alternate solution will be needed(got it in, forgot the paste? nothing suitable to hand, no retaining screw), and I suppose a good time to go high temp, M4 thermistor think I need this one....[www.ebay.co.uk]

but not sure I could get that working with the SKR Dip...may decide it's best in the cube printer due to the direct drive making it easier to grip/mount this hotend, but not sure plastic bmg types are ideal either(scratch that it doesnt fit) so might need another metal version.

Idler arrived to tidy the other machine up

Looks like I didnt have to worry about the ship sinking, this little guy must have helped out, it was only after hitting the buy button I realized the DIP was 1.1, not sure what the issues with the board are, or if i'll run into them, let's hope the issues are avoidable, marlin 2 here i come, even had a microsd in the bag.

Suppose by the time I get some 2209's it might be more cost effective to get a better board?

Almost at the end of the roll....don't think I have enough left for the lid, considering I live by the sea & the roll has been out of wrapper for a year, I'd say it performed great to the last drop. Toying with the idea of a base for this case so it could hide some cables, otherwise I could have done more to manage the cables internally, maybe on the back of the lid, could have put a larger fan on the lid as I dont really know what these 24v 40mm's sound like. Wondering about a small silent 24v psu, a little cheaper & smaller than the slim meanwell 350, I dont have any 24v psu's but I suppose one good one is worth investing in, or something even beefier with other stepdown units? Scratch that the smaller the better...maybe a laptop psu, no heatbed at the moment.
