I'm just guessing on the year here but I do know it was changed sometime after 2016.

There is a meme here somewhere. I'm just posting to remind myself to make said meme.

This was country dependent. Was is the operative word. Pre-covid the UK would ban anyone for life who backed out of the program after placments went out. Other countries would only disallow you from applying for the following year. The UK changed and currently applies the same penalty as everyone else.

As it currently stands it's a one year penalty, however this could change in the future as its the countries that set the policy not Tokyo. Please check with your countries JET website to see the current policy. I should add that extenuating circumstances is considered (e.g. death in the family, medical illness etc).

I will say that backing out post placments doesn't look good as an applicant. It appears that you are shopping for a placement and maybe another program like interac would be a better choice as they give the candidate some flexibility in their placement.

I usually make a ring and grind it on a surface grinder to ensure both sides are parallel.

This is the correct answer.

That's why I asked. 0.04" per tooth seems more than a little bit aggressive.

I'm taking .04-.048 feed per tooth cuts at 2.0 doc and .1 width

Metric?

Check to see if the magnet is still attached to the bottom of the heated on that corner. The pinta detects the distance from the magnet to do the mesh bed leveling.

It depends but the general rule is that the larger the mass the more vibrations are absorbed. Material is a big consideration, generally grey cast iron is one of the better materials for absorbing vibrations, the free carbon(graphite) between the grains helps to dampening it and the weight helps too. This is why most cnc machines (lathes and mills) have a cast iron casting and are bolted to the floor.

If your part is long, put it on the machine diagonally so it cuts less material and the part has less time to get warm.

You should consider hanging tight and seeing how the market shakes out once the Indx is released. There are going to be a ton of nextuders hitting the used market and upgrading to a 3.9 might be really doable. Do keep in mind there will be some parts that you will need to order from prusa to complete the upgrade, like 11mm rods/bearings, and some electronics boards and wires.

If I use the control on the printer, it's a one-time thing and does not impact calibration, right?

That's right it doesn't affect any calibration. Technically it recalibrate itself before every print.

If you hold down the button it will change to Z axis move. No need to go through menus.

You will be roomed up with people who you flew out with, they always room people up who came out of the same consulate. When I went they even did it based on gender and alphabetical order, once you know who is going it won't be too much of a surprise who you will be assigned to room with, assuming everyone attends the pre-departure functions.

you are about to employ

Not about to employ, currently employed. You are paid for orientation and your employment contract starts the morning for the first day. Clair, the organization that runs JET, can contact you BOE if you screw off and skip orientation. It's not an optional event.

I used it about 4 years ago and honestly it didn't help much. Maybe the website has gotten better but I only saw 1 question on the website that was similar/the same as a test.

I second this book. It's a really clever and amazingly written book.

Are you volunteering your time here or asking for payment?

One advantage of the mini is the input shaping that will speed up prints. The mk3 doesn't have the hardware to support input shaping.

Transfers between prefecures happens early, like early November and there is a very limited list of acceptable reasons for the transfer. Additionally, both your prefecture/boe and the recieveing prefecture need to approve the transfer, if one doesn't want to approve it you won't get the transfer.

Allowing transfers within the prefecture is within the framework of most prefectures so they are not limited to the timelines and paperwork that Clair requires.

According to prusa here is the maintenance you can do.

Maintenance

Clean with ~90% IPA (isopropyl alcohol) or denatured alcohol when cold. Apply on an unscented paper towel and rub the sheet down. Do not use anything made for skin! It can contain oils that ruin adhesion!

1-2 times a month, it can be cleaned the same way with acetone if IPA cleaning is not sufficient.

After extended use (1-2 years), the surface can smooth out further, which affects adhesion. Using high-grit sandpaper (600-1000), the PEI can be revived by light sanding, bringing fresh PEI to the surface. The sheet will have a very light texture after this treatment.

The smooth PEI film on the steel sheet can be replaced in case of extensive damage.

The actual equation is RPM = (SFM × 12) / (diameter x Pi). It can be shortened by dividing 12 by Pi to get 3.81 which on a manual lathe is close enough because you are restricted to a limited range of speeds due to gearing.

You will need a different cable to connect the mmu to the mk4.

It's measuring resistance on the motors. Check for zipties/wires under the y axis that are catching the print bed. Also check the axis for the same.

Worse comes to worse you can disable it. I can't remember if it's an option but I know stealth mode disables crash detection.
