So it has been 3 months since we started shipping the MK2. I would similar to give you lot guys a little update and show what we already managed to improve during this short menstruation of time 🙂

We weren’t quite set for this kind of increase in orders.
Thanks guys!
We basically had to double our production charge per unit during one month and together with new printer design, it wasn’t easy. Fortunately nosotros had a new arrival to our squad just in time. Martin, with great experience from large scale manufacturing Foxconn.
Finally, as of now, we were able to lower the atomic number 82 fourth dimension to 0! Yeah!

Just before we commencement, let’s have a look where we already shipped
Original Prusa i3 “MK1”
and
MK2.
90 countries! WOW!

The map shows every ZIP lawmaking with 1 or more Original Prusa i3s MK1 or MK2. The map doesn’t contain whatever sensitive data. If you want to see the map in bigger screen, here’south the

Printed parts

Printed parts were the showtime struggle. You simply can’t increase the speed of printing to produce twice more parts.
This was our limiting factor at the beginning.
Even though we were already examination building MK2s in firm for a couple of weeks prior to the shipping,
we quickly realised that parts that are strong enough for our guys in assembly aren’t always strong enough for existent world builders.

When I noticed couple users having problems with the parts I jumped in and started tweaking. First thing I had to do to exist able to optimise the press procedure was to standardize the print subcontract, we had switched the subcontract to MK2 completely. This took roughly a week and I started to prepare other tricks I had in my sleeve. Before that we had a mix of various 1.75mm revisions fifty-fifty including quondam prototypes and some really really old 3mm versions at the subcontract.

I called our filament manufactory to mix a new colour of
EasyABS
matching our signature orangish. The material has
meliorate layer bonding
and on the MK2 we tin can also push button the temp higher to increase the strength even more. If y’all are curious, we are running them at
270°C
and impress speeds are between 2.v to 3 times faster compared to stock settings in Slic3r.

Another comeback was to make the parts which were breaking selectively stronger. Simplest way is to
place very thin 0.05 mm slits into the problematic area.
This forces every slicing software to fill the area with perimeters and effectively making
100% infill where needed.

The actual print time of i printer is around
20 hours
. That is pretty awesome considering the behemothic parts like PSU and LCD embrace. The farm is at present fully populated with MK2s and the daily yield is around fifty parts sets. Every bit a bonus, we save a lot on the ABS juice at present 🙂

We also had to develop our ain
impress monitoring software monitoring
available print time utilization, farm space utilization and
gcodes success charge per unit
statistics. Simply I’ll write about this sometimes later in a divide article.

Firmware tweaks

We were idealists and idea that users employ our print profiles. Oh boy we were incorrect!

The very first printer which was shipped, the user downloaded a random 2-year old Cura from net and used config for a clone of Prusa i3. This unsurprisingly damaged the printer so we started putting more rubber measures into the firmware. Nosotros managed to patch almost everything during i day even at the toll that printers were running the calibration twice. Twice is meliorate than none at all 🙂 At least for a poor scratched PEI sheet.


We bought all the PEI bachelor in Europe
until the next production run in 4 months and then we have enough for manufacturing and you can buy replacements on our e-shop. Be careful with the PEI though,
no chisels, no knives, no xacto blades, … sharp spatula with round corners is your all-time friend.

With other parts, we don’t have them on the shop every bit we are bound to sell them at MSRP and can offer them cheaper to our customers when contacting u.s. via e-mail or in the instance of the
MK42 heatbed we simply don’t take enough
to sell to full general public and reserve all for production and occasional replacements. This should get better over time as nosotros are getting more suppliers in.



Properly assembled printer

Since and then we are working on a
new firmware, which can
detect the exact position of the calibration point
on the MK42 bed and relieve them for later on calibrations. This means, users tin be less precise during their build!
It is basically a blackness magic!
Cheers to this characteristic we afterwards found out that we can utilise the very same data to compensate for non perpendicular X and Y axes. If you build your printer in a way, that X and Y are non precisely at 90° your objects will exist crooked, simply non with this function on the MK2. Information technology is besides present in the firmware since version
iii.0.6(3.0.8 is the latest at the time article was published) and it is pretty much revolutionary.
Read more virtually the
3.0.6
and the
new calibration period.

We also wrote an

commodity about the magic

how the firmware can correct skewed geometry on imprecisely congenital printers.

Calibration flow

Yous tin can take a look on the whole scale procedure in our latest3D Press Handbook. Next footstep is to design a printer completely out of a cardboard, dental floss, hot gum and let the firmware compensate all the imperfections 😀

Drivers

We applied for
EV code signing certificate, then drivers starting with ane.7.3 will always be signed. No more red screens and warnings, yay! This as well allows us to sign the USB serial driver and later the Win10 3D printing support when MS guys release the new SDK version I developed the printer settings for.

The
Original Prusa i3 MK2
has its own
USB ID, and from drivers
ane.7.3
you tin can see information technology in the device manager under its proper name and on all versions of Windows.

Slicing tweaks

I am continuing to tweak the slicer presets and test objects and we already accept a total time developer on the bodily Slic3r itself.
Vojta is slap-up!
We now have much more than
stable version of Slic3r
that even includes
grid infill!

The 64bit version allows you to print more circuitous models and has faster export times. Equally a trivial bonus, it now has
anti aliasing. Information technology also has fixes for
cut part
and
ship to octoprint
functions.

Scale

Nosotros originally started shipping the printers with
fancy calibration script
printing circles and possibility to
select which turned out the best. This proved to exist
besides complex
for newcomers to 3D press. We eventually created
V2 calibration, where the nozzle just prints a
zig zag pattern
and user
slowly lowers the nozzle
until he achieves the optimal height.
It’s a fleck similar landing a plane. And every bit already mentioned in Firmware chapter, starting withiii.0.6 firmware
(three.0.eight is the latest at the time commodity was published) nosotros created a new calibration flow that should solve all the user problems with calibration. Hopefully everything will exist
smooth from at present on
🙂

I am extremely grateful for the positive attitude towards the MK2.
For case everyone who asks what Prusa i3 to get, getsOriginal Prusa i3 MK2
as an reply from the community. Same happens on the Facebook. All-time thing is, at that place are reviews to back it up. Just check out the

Cheers guys for your standing support!
Every bit a little gift for the delay we added a nice
