What is the project/machine/module?

43 min to drill and tap 5 heatsinks for Universal, starting from 2" stock aluminum

17 minutes to QC one control panel minus extruder. 22 to bag it up. Could be much quicker, possibly 5 minutes, if everything is laid out well. This checks cables, steppers, LCD, power supply, RAMPs drivers, USB power, and upload of firmware.

Control Panel Kit 1-5 being sent to Europe. #1 to Fouad, and #2-5 to Michel. #4 appears to have issue with Y1 driver slot - maybe the capacitor there was damaged upon removing diode for 24V conversion. Also, light on 24v supply does not turn on, but supply works.

Eliminate endsrops and make printer quiet

Get fans and blowers that already have long wires

9 minutes to cut off and bag 6 endstops and repin their wires for D3D Universal

QC of 1 pair of endstops - simply plug in and trigger upon Prepare-Home in Marlin. Takes less than a minute.

42 minutes to make 6 D3D Universal endstops, v20.01

About 1 hour to heat tighten and put heat sink on 4 D3D Universal v20.01 hot ends, ready for mount to extruder.

47 minutes to drill and tap 5 heat sinks, starting from 2" aluminum stock. Includes jig for hole marking with transfer punch,

On home, x homes, then y homes only a little bit before z starts homing.

Move screen over 3/4" and make holes in control panel and run wires from power supply under the panel

temp of 90 set means 63 C with IR thermometer.

Use G92 E0 to zero extruder at beginning of print

Whatever position extruder was in last time, zero it so it doesn't extruder.

Pleurotus Ostreatus self-seeded on pond lumber!

2015 Greenhouse - Temperature in Pond 1 (close to house) - 60F. Pond 2: 62.4F with PV from Faculty house and 4.5 kW heat element, direct DC

Looks like poor load matching of 540V OC of panels to 240V of heat element.

Tine bars are 10.5" on soil mixer.

24 min to poke 200 holes in Keyline for hazels. In loose falling soil

3 hours to plant 175 hazels - or one per minute. Includes Keyline rip plus flail, mulching, spraying, and watering.

Flailed grass is ready and clumped for mulching.

1 minute per plant for poke hole - plant - mulch - spray. 25 plant test.

Mulching with flail mowed hay so far has a 100% effectiveness for rodents when including egg spray. Visual hiding and dry grass is not liked - as opposed to bare ground.

Planted 500 hazels with rod holes into keyline in 8 hours. Egg spray + watering included.

When soil condition was loose so could break up soil in trench easily with hands. Not too wet or dry.

4 hrs for 1 person to install 500 feet of three quarter inch tubing at the ceiling for the 3.5 kilowatt heat exchanger

It took 6 PM to 10 am - 16 hours - about hour per shelf. to install and check 13 bottom watering shelves. 1.5 hours each. Each fitting took 1 hour to print (check Nut Breeding page for details).

Well parallel labor work. Overspill happens with 1/8 HP pump, if watering one at a time - watering 6 banks (of 3) at a time would address the spill. Some weep holes get clogged.

From 5:30 pm to 4 am to set up 68 feet of shelf, including working around 100 nut trays. 1 person.

4 hrs to install all brackets for 20 foot shelf 3 layers - plus one full 20 shelf loaded with plants.

4:30 hours to. Hold a set of shelves from.the point of bracket with 1' of wood, then load with plants.

25 min to put on 15 2x4 one foot stubs for shelves

1:20 HR to put up brackets on one side of greenhouse - 48 feet of shelves.

10 hours to unpack, and 5:45 to further prep the inventory. See http://opensourceecology.org/w/index.php?title=D3D_Inventory

24-28 lb wet weight of 98 tray, sc7 or sc10.

Nursery plantout: dip tank takes a lot of time to fill tub - should have a fatter hose. Soil loading with lever from overhead would help - 2 hands smoothing and foot opening up a valve to deposit soil.

9:08 going right hand planting.

9:20 to seed one tray of s7 hazelnuts

1:23 to fill one s7 trsy with soil

1:23 to fill one s7 trsy with soil

12:50 to seed one tray of hazels with long roots in miracle gro medium

Planted 24 trays in 6 hours, one of these tall. This is hazels, tall is Chestnut. 400 per hour.

14:30 to cut 10 trays - legs on table saw for deepots

15 bales of hay harvested in one cutting at FeF, 2015

Once again extruder mount screws should be 40 mm, not 35.

Once again extruder mount screws should be 40 mm, not 35.

Inventory - cut step - cut belt in 2

Prusa Build 2 - missing one bed spring.

New build data from scratch

2:50 to fill tray with tubes after efficient method

17 minutes to plant one tray of big sorouty chestnuts

6 mn to fill one sc 10 tray without scoop

3:50 to fill one rl98 tray with new sc10l pots

QC - Aluminum bed connection to the linear bearing holders need to be 18mm, not 20 mm. With 20 mm, they bottom out the heated surface, and bed can't be leveled easily.

QC - D8 connection instructions reverse the heatbed polarity. Wiring (+ and -) is opposite that shown in standard RAMPS wiring diagrams.

QC - make sure the z bearings are all the way in. If not, they prevent endstop from activating.

Endstop mount for x axis is such that end stop body hits the carriage, and end stop does not activate.

QC on inventory - 20 of 18 nylock 3mm nuts were given. Even with this, we are one nylock short. So bom appears to be 3 short. To make up, I used 1 and not 2 nuts on the x end stop.

QC - x end stop has 2 m3 bolts, others have only one.

QC - make sure polarity is correct on fan wire - red to red, and red to positive on power supply.

Qc - Use shrink tube not welfare to do the fan wire connection.

QC - take off power supply to make the proper wiring attachments

Wire length between PS and controller is 200, not 240mm.

Qc - Y motor should have wires facing forward, not up, so they don't get cut by bed.

To attach m3x20 to the end stop after mounting on a rod, drop the nut in the not lock and tighten the screw from the panheads side using a long handle round Allan key

QC - bolts for end stops are m3x20, not 18. The ones provided are 20 and 16, no 18. Packing list is correct, instructions are not.

QC electronics panel - panel orientation matters. To prevent doing it multiple times, attach with 3 screws prior to mounting on frame, with connector on upper right side and wide spaced mounting holes on the left.

QC electronics panel - panel orientation matters. To prevent doing it multiple times, attach with 3 screws prior to mounting on frame, with connector on upper right side and wide spaced mounting holes on the left.

QC - control panel - to assure proper orientation

Make sure you tighten the z axis rod clamp - which you can't see is not tight until mounting the electronics panel, where the z axis top bar lifts up.

QC on heat sink attach - make sure the heat sinks are not so far off the FET that they ride the side pins and don't make good contact with FET.

Make sure pololus are not reversed. What happens if they are reversed? Is it easy to shift their voltage setting by mistake?

QC note - acrylic mount is missing its screws as they were used for power supply corner bracket attachment to the frame.

QC - electronics mount acrylic - do bottom hole first, otherwise you can't get t nut under acrylic.

Qc - for the 4 mm panheads to catch on the corner bracket, the screw must be on the edge of the slot. This means that m4 is foo small for this, screws used should probably be m5. Since there are only 4 of these corner brackets, nobody probobly bothered to notice.t.

QC - it is difficult to attach the power supply using 8mm standard m4 route, because the corner bracket is rotated 90 deg from its usual mounting position, where it no longer sits flat on the 2020 because of protrusions that don't go inside the rail. This, use 4x10 metric panhead screws.

It took me like 10 minutes to stop trying the 8mm, and it worked pretty much immediately with 10 mm.

Front idler bolt too long, in way of wrench.

QC - needs belt tensioning. Belt snapped to looseness when z axis bent in slightly because the y rods can slide a little. Y rods need to be secured in place, possibly cut to exact length.

QC part inventory - the 3 mm screw for the extruder attachment is 35 mm, should be 40 mm. Cant attach extruder now

QC - x axis idler - I put in a washer spacer because of the inside gap

Z axis skew (but still parallel) is seen by bottoming out the z axis motion, and seeing if both right and left carriage sit on bottom frame at the same time.

QC - when mounting the z axis frame, check the 2 perpendiculars after tightening slightly - if OK, tighten firmly. I had to loosen z frame because it was slanting, which became visible only after checking z motion when mounting z motors.

QC - z carriage rides smoothly, moving it up and down without z rods aligns the vertical parallel.

QC - tape up platform wire bunch as soon as platform is made to keep things organized.

Platform bearing screws should be 2 mm shorter, as the heated bed almost touches them. This is critical. I used #8 nuts as spacers.

QC - bed orientation is two bearing side on RHS.

QC - coupler on z motor - tighten 1/8 turn after the round Allen wrench

QC - when attaching z to y, attach gently and then loosen. This will make things adjust.

QC - when attaching z to y, attach gently and then loosen. This will make things adjust.

QC - spool holder on left when connecting z axis to y axis.

Once z axis frame is installed, vertical tolerance is zero, as the other side of the vertical is not yet tightened..

Tech ique for L brackets and set screws - Allan with handle vertically, then lower bracket onto it.

1/3 mm corner offset compensation jig should be created?

Actionable - find out length tolerance of their 2020 cuts.

Member cut length accuracy is +- 1 mm.

Tightening 2020 corner set screw creates linear motion of about 1/2 mm. Keep tightening down to +-200 microns by compensating for this motion.

Corner 2020 GD&T - 1/5 mm or 200 micron for corners
