- Original Prusa i3 MK3 has been added to the fleet
- printing of the MK3 enclosure is current priority over further AM8 upgrades
- AM8 works great, often bed-leveling process is 🙁
- noisey AM8 drove me nuts, started ‘blipping’, replaced with Noctua fancy ass thing
- All four(4) of the nuts on the left side z-axis ball-nut carrier fell out, 20 minute fix
- I’ve been printing for the past couple weeks now with this machine, without any problems other than re-leveling the bed every couple days. It appears that the micro-switch is bending and not springing back instantly. So, the bed ends up a bit out of correct. I understand the desire for auto-leveling, and will upgrade to Marlin and a bed-level sensor after printing the enclosure risers, accessories for the MK3.
- The spring nuts on the ball-screw for the Z-axis rattled themselves apart, which required putting that back together, and a re-leveling.
- The Noctura fan makes this printer very quiet, and the linear bearings run smoothly. When/if this one gets noisey I will rebuild it using MGN12 rails.
Project Goal: Cheapest Badass Printer
- Anet A8 off GearBest for $150
- AM8 frame upgrade $50
- mosfet bed heater $8.59
- fiber GT2 belts $10
- Decent Tap
- JST XHP crimp pins and connectors Also, JST Crimp tool
- JST VH pins for the heatbed power upgrade
- Screws assortments are a lifesaver. this and This and This
- microsd-slot extender $10
- PEI sheet for the bed $15
It begins, finally received the AM8 parts.
For ease and cheapness of build, anything that isn’t really under a lot of stress and is a good distance from a heat source, I printed in PLA. Anything important I printed in ABS. Some pieces of the system I will remove from any proximity to the frame anyways, as it’s final home is figured out. So, for 1st assembly, PLA is fine for a lot of this stuff, is what I am figuring. All the 3d printed pieces of this project were printed with a Prusa I3 MK2, I have been printing with the Prusa for a year or so. The Prusa is enclosed, and well sorted machine, easily prints ABS, PETG, PLA whatever.
base frame assembled, still waiting on feet, some minor dissassembly to come, nothing squared up, nothing locked down.
- Y-axis motor mounted
- Y-axis rods and bearings seem ‘good enough’ for now. For a proof of concept, is good enough. Upgrade to H-bed and bearings here
- H carriage mounted, finally found a good and adjustable y-belt holder.
- Frame is squared up
- Feet are mounted, X-axis tomorrow
- Z-axis extrusions have been tapped and mounted
- Z-axis aligned and squared to frame
- Heatbed strain relief printed
- Fan gaurd for the mainboard fan (used an old 80mm computer fan I had laying around)
Why do I have these entries labeled by day?
- Assembled and installed X-axis
- lcd and control mounted
- Power supply switch upgrade
- printed Power supply switch cover
A Week Later:
- Power Supply housing printed for the AM8 frame, switch mounted and wired
- Dual Mosfet Holder for the AM8 frame printed, mosfet mounted and wired
- Wiring and routing has been roughly figured out at this point, at least for calibration phase. A lot of unsupported sharp bends that need solved to become a real printer. Printed wire clips for AM8 frame
- Hotend mounted on X-axis and X-axis belt tensioner printed for Anet A8
- microsd-slot extender ordered
- PEI sheet for the bed ordered
- Power wires added to heat-bed. As pictured here. Crimp connector used. Crimp tool used
- Ikea Lack table ordered for an enclosure
- Printer moved to it’s permanent home
This is basically the step where I think we have exceeded our $250 price target, but given the effort to this point, now this printer is a test mule for upgrades. Yes, linear rails are being figured out. Now. No real hurry due to New Year’s.
- Printed Y-axis belt holder, works great, good geometry.
- mounted x-axis belt tensioner
- Everything works, mosfet for the heatbed works perfect, bed goes to 100, no problem.
- Printing risers for lack enclosure, will be typical perspex stuff, but solving it with 18mmx3mm neodymium magnets for closure. printing new filarment guide and spool holder, hopefully first print wednesday night?
Setup and First Print
- Bed leveled using the method Here
- 1st print achieved on the packing tape the bed came with, good ahesion
- 2nd print, did a benchy, good adhesion, finally tore the packing tape.
- PEI surface applied
1st benchy (2nd print on packing tape)
2nd benchy same .gcode (1st print on PEI)
- Ikea Lack Table
- Lack Table Risers
- Lack Table Filament Guide
- RGB Light Strip kit
- Light strip clips
- Spool holder (Best one I have found)
- Hardiebacker for the floor
- Rubbery spacers between cabinet and hardiebacker floor
Many people have had fires for various reasons with these Anet A8 printers. As a precaution, I have placed beneath my printer on top of some hardiebacker (tile floor underlayment) to provide ‘some’ fire protection. Especially since it is on a wood cabinet. The cabinet itself was previously used to hold a 100 Gallon aquarium. It is basically a 2×4 frame structure lag bolted together. Beneath it is enough space for a CR-10 printer and a couple of 5 gallon buckets for filament storage.
The story begins in late June, the decision is made to make an effort to shoot the eclipse, the goal being to create a printable work. The scope and scale is determined, we will drive 4-6 hours any direction and chase the sun. Surely, we can get to sunlight given some solid commitment.
In July, a 600/f4 AI-s is aquired, along with a TC-301
Friday (3 days to go)
coordination between the teams, the groups, we have access, and accomodation at sites ranging from Boonville to Cameron to Joplin.
Saturday (2 days to go)
A bit further planning, but the weather is uncertain, at this point, our current available arrangements where we can have Claire entertainment, and a livable situation are Liberty MO, Smithville MO, Weston MO, St. Joseph MO, and Boonville MO. The outlook is iffy at best, but we are hopeful (or delusional).
Everything looks pretty bad, no bright spots unless we were already 6 hours West. Going to bed is ‘Hateful Eight’ level nervous. The sky-cast percentages favor Lee’s Sumit MO by 2-4 percent. At this point, this is all we have to go on, we are chasing a storm, and whatever guys at the National Weather Service or whatever are updating often. Since everywhere is hopeless, we take the best odds we can get. And stay home.
It’s raining. It’s been raining a while. Lynch arrives, we have some breakfast, and unload his gear to the basement.
We’ve committed to the optimism that somehow everything will clear for my house. (last night and still today, we have a 3-4 percent advantage on everywhere we were considering goin to) It’s a thunderstorm, we are running our 200mm lenses with ND16 filters doing lightning shots.
Moral is low. The clouds surround us completely. We have made a bet that this was ‘the’ spot to be, and it is now appearing completely delusional. Skycast continues to waft our dreams of an eclipse shot.
We see blue sky. It’s still slightly sprinkling, we deploy anyways, our cameras have some kind of weather sealing, and we know this 600 has seen much worse. Somehow, against, the greatest of odds, this is suddenly possible. 20 minutes ago, we were hopeless, consoling ourseleves that there is no-where we could have gone to escape this cloud. The eclipse chasers we are talking to are in worse shape, they can’t see any clear sky. And yet, there it is. We see it, it’s going to go over us. just a few minutes before eclipse begins we have a clear view.
This is the Sun, with a Baader Solar filter, one of the first shots we got, eclipse has not begun at this point.
We had both rigs up and operating at this point
The above shot is a bit surprising as the abundant sunspots really only show up since there was so much cloud cover. These pictures are not color ‘adjusted’ at all, the color difference is a result of the types of solar filter being used here. I’ll list complete details of the equipment a bit later on.
The clouds cleared, and the eclipse began. The absolutely tiniest part of moon is encroaching. You can juuuuuuuuuuust see it.
Clouds persisted, for about a 1/3 of the prenumbra
I have no explanation. The sky stayed clear. Great hope lies with us.
And here we are, the greatest conditions possible.
Clouds moved in shortly after totality.

“It is not the critic who counts; not the man who points out how the strong man stumbles, or where the doer of deeds could have done them better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood; who strives valiantly; who errs, who comes short again and again, because there is no effort without error and shortcoming; but who does actually strive to do the deeds; who knows great enthusiasms, the great devotions; who spends himself in a worthy cause; who at the best knows in the end the triumph of high achievement, and who at the worst, if he fails, at least fails while daring greatly, so that his place shall never be with those cold and timid souls who neither know victory nor defeat.”
― Theodore Roosevelt
Team Emery I got an opportunity to shoot, I link my shots here. I will continue to add more pics to the set, as I process them.

This story begins with a roommate I had at Mizzou who used to show anyone he kind of liked his slides. He would project them up on a Kodak projector, and they were mostly amphibians and lizards that he had photographed in his hiking travels. He was talented, and would go on to pursue a lifelong passion of shooting nature and landscapes in exotic places. I think, roughly then, is where this story begins. I was fascinated by the process of this, at first, it seemed to be just a problem of equipment, but, like most passions, this is a thing that cannot be bought.
The story of me shooting film, begins some years later, when I had time and energy to devote to it. I started with an old Pentax ME and a few lenses, and switched quickly to a well beat up Nikon F3. 7 years later, and many rolls later, I picked up a Nikon D40. This was a few months before Claire was born, and I’ve been digital ever since. That was 2013. I recently stumbled across a cache of shot and unshot film, and figured I would take a full manual film camera on a ski trip. So, here we are.
Let me explain this picutre, my favorite. I shot this on the far Earstern side of the mountain, on a run called St. John’s, at the top, looking out over Jackson. The pictures on either side of that shot were both boring crap.
The few rolls, the few moments dedicated to pure indulgence of a nonsensical viewpoint was a rewarding challenge. An effort to get, something better than I expected, to get something through a process that you only have one (1) shot at the moment.
Film still works, it’s till workabable, and it can still be yours.
