00:00:00,120 --> 00:00:07,839
a year ago we took a look at the prusa markv today we're looking at the prusa

2
00:00:04,600 --> 00:00:10,040
Mark 4S which is a big upgrade and for

3
00:00:07,839 --> 00:00:13,920
the same price or if you already have a markv only a $100 upgrade kit so we're

4
00:00:12,679 --> 00:00:20,519
going to take a closer look at some of the upgrades that theyve put into it

5
00:00:17,080 --> 00:00:22,320
we gummy bears as always we use the

6
00:00:20,519 --> 00:00:25,960
crues around the office quite a bit they're one of the workhorses we have

7
00:00:23,800 --> 00:00:29,679
around here and I'm looking forward to adding these

8
00:00:28,199 --> 00:00:33,000
ones to our Arsenal and upgrading the ones we have to

9
00:00:35,559 --> 00:00:42,559
this as always another USB stick

10
00:00:39,079 --> 00:00:45,559
anything else hiding yes many things

11
00:00:42,559 --> 00:00:46,800
hiding more boxes in this box we have

12
00:00:45,559 --> 00:00:53,760
the accessory kit which has a bunch of tools a

13
00:00:50,719 --> 00:00:56,800
filament guide spool holder and some

14
00:00:53,760 --> 00:01:00,120
lube and a couple of other odds and ends

15
00:00:56,800 --> 00:01:02,120
and a spool of filament Galaxy black

16
00:01:00,120 --> 00:01:07,680
always pretty most of the parts of this are similar to The markv but there are

17
00:01:04,680 --> 00:01:10,080
two big improvements one is the part

18
00:01:07,680 --> 00:01:14,759
cooling shroud and fan system which is going to allow for faster Printing and

19
00:01:12,680 --> 00:01:19,080
way better overhangs and something we can't see right now is a new hot end to

20
00:01:16,759 --> 00:01:23,000
allow for way higher flow rates some of the other quality of life upgrades are

21
00:01:21,400 --> 00:01:27,000
the screen cover which is now injection molded and some of the more mechanically

22
00:01:25,320 --> 00:01:31,200
robust parts are printed out of a polycarbonate carbon fiber infused

23
00:01:28,799 --> 00:01:35,920
filament the unit we got was fully assembled so just take it out of the box

24
00:01:33,200 --> 00:01:40,079
put it down plug it in and go they say it would take you about 10 minutes to

25
00:01:37,600 --> 00:01:44,040
get from out of box to your first print let's flick it on one of the other

26
00:01:42,119 --> 00:01:47,600
things they've released is a mobile app and an update to their desktop app this

27
00:01:46,479 --> 00:01:51,840
allows you to browse through your printers start and stop prints and you

28
00:01:50,560 --> 00:01:56,799
can set up print notifications for either failures or successes and other

29
00:01:54,159 --> 00:02:00,360
General printer status information setup pretty straightforward you just tap the

30
00:01:58,439 --> 00:02:06,240
NFC with your app going and scan a QR code to get it set

31
00:02:04,159 --> 00:02:09,520
up as with all PR printers you don't need to have it set up to the Wi-Fi and

32
00:02:07,920 --> 00:02:13,239
you can print completely offline if you want to let's finish up the self tests

33
00:02:11,720 --> 00:02:18,959
and calibrations it's going to go through and just make sure that all the systems are behaving the way it expects

34
00:02:16,480 --> 00:02:23,319
to make sure that it arrived in fully functioning

35
00:02:20,519 --> 00:02:28,239
order hi there o nice and quiet

36
00:02:30,080 --> 00:02:35,040
one of the things I appreciate with the prusa systems is they go through the

37
00:02:33,200 --> 00:02:38,519
self testing calibration right at the start and then after that you pretty

38
00:02:36,879 --> 00:02:41,920
much never have to recalibrate them unlike some of the other systems which

39
00:02:39,879 --> 00:02:45,959
run it before every single print which can take a lot of extra time when you're

40
00:02:43,599 --> 00:02:51,360
running a lot of prints it's all the main axis

41
00:02:47,640 --> 00:02:54,280
done and heat testing this might take a

42
00:02:51,360 --> 00:02:58,920
minute that's probably a good time to cut cut cut cut since we didn't build

43
00:02:57,519 --> 00:03:02,720
this printer ourselves we don't have to deal with the gearbox test but from what

44
00:03:00,959 --> 00:03:05,680
I've seen it's pretty straightforward all right now we're

45
00:03:04,519 --> 00:03:11,879
going to take out the filament and make sure the filament sensor is working correctly insert filament make

46
00:03:09,799 --> 00:03:15,400
sure doing more calibrating and

47
00:03:13,799 --> 00:03:19,599
remove sweet happy printing now that the

48
00:03:17,920 --> 00:03:23,280
printer is all set up and ready to go let's give you a word from our sponsor

of mind they need by heading to the link in the video description to learn more

55
00:03:45,640 --> 00:03:51,400
while this is heating up one of the other changes they made was to put some

56
00:03:49,360 --> 00:03:55,079
more bearing style engineering materials on the inside of the gearbox housing

57
00:03:53,439 --> 00:03:59,879
just to give smoother running in the long term generally speaking prusa

58
00:03:57,720 --> 00:04:04,560
doesn't push printed as fast as you possibly can but one of the things they

59
00:04:01,879 --> 00:04:08,280
did include on this is an 8-minute Beni which I'm very curious to see how that

60
00:04:09,439 --> 00:04:13,239
runs that was really

61
00:04:13,599 --> 00:04:19,639
fast and it looks really good especially

62
00:04:17,120 --> 00:04:25,280
given how quickly it printed obviously not a regulation Beni it's a little

63
00:04:21,320 --> 00:04:27,560
Hollow but still for how quickly that

64
00:04:25,280 --> 00:04:31,039
printed this looks spectacular one of the big things that

65
00:04:29,400 --> 00:04:36,080
they claiming is to be able to handle 75° overhangs without any support

66
00:04:34,120 --> 00:04:40,039
cleanly I've done a couple of test prints on some of the other printers we

67
00:04:37,880 --> 00:04:46,160
have in house we'll start a print here and see how it turns

68
00:04:42,199 --> 00:04:47,759
out overall I'm really excited for the

69
00:04:46,160 --> 00:04:51,960
upgrades that this brings and I'm probably going to reach out to them

70
00:04:49,479 --> 00:04:55,720
today to get a bunch of kits to upgrade all of our printers internally cu the

71
00:04:54,280 --> 00:05:00,360
speed Improvement and the quality improvement looks substantial and all of

72
00:04:58,600 --> 00:05:04,680
these upgrades coming at the same price point as the original printer at $800

73
00:05:02,440 --> 00:05:08,080
for the build your own kit and ,100 for the

74
00:05:05,600 --> 00:05:10,840
pre-built it's pretty compelling if you want to see us talk about other printers
