Prusa Inquiry released version 3.x.0 firmware for their flagship line of 3D printers.

The new firmware targets the MK3, MK3S, MK3S+, MK2.five and MK2.5S platforms, and every bit e’er is released as open source software on GitHub. It’s gratuitous to download and employ for anyone using those platforms, or others, I suppose, who are building Prusa clones.

While a firmware update may seem similar a minor thing, Prusa Enquiry described some of the attempt required to produce 3.x.0:

  • 4500+ printing hours during our in-business house testing
  • 867 commits to the source code
  • fourscore pull requests
  • 11 contributors (5 of them external)

That’s pregnant. Just what did they alter in this version?

A change in the display of time remaining has been implemented. In the past the machines would prove yous the elapsing expected until the entire impress chore completed. That’s fine, just what about planned filament swaps? These crave operator intervention, and if in that location’s merely one deep into the print job, what does an operator do? Exercise they hang effectually the car waiting for the swap to trigger at some unknown fourth dimension?

To salvage everyone some quaternary dimension, the “time remaining” feature now flips every five seconds betwixt “consummate” time remaining and “fourth dimension to adjacent bandy”. That way operators tin far more easily manage their time around the auto.

Another comeback fixes one of the features that always bothered me: boring response fourth dimension for file discovery. When you remember a list of GCODE files on the SD carte, the machine would take enormous amounts of fourth dimension to get through the list. It was so ho-hum that I gained the addiction of quickly deleting every used file on the SD card to minimize delays.

Now that problem could be extinguished by firmware 3.x.0, which speeds upwards alphabetical sorting past 10-15% and past fourth dimension an enormous 2-4X. Sorting by time is my preferred brandish considering the file you only stored on the SD pecker of fare is eastward’er at the summit of the display for easy access.

Prusa Research has besides completed recoded their XYZ scale routine. They say the procedure is now much faster and should event in a more precisely calibrated Original Prusa device.

Support has been added for gigantic 0.8mm nozzles, for those who endeavor to print very large objects speedily on the relatively small device. The 0.8mm nozzle has 4X the area of the standard 0.4mm nozzle, and then in theory impress jobs should take almost ane-quarter of the time. Imagine your seven-hr task completing in only 105 minutes!

1 interesting change has been a serial of minor tweaks that should brand the machines easier to piece of work with remote control systems such every scrap OctoPrint. For case, instead of OctoPrint having to poll the device with M105 commands to discover out the current temperatures, the new M155 control needs to be executed just once and it volition automatically report temperatures periodically.

And there are dozens of other upgrades, enhancements and fixes you can view in the GitHub documentation.

Withal, later on reading through all this it seems to me that these machines are increasingly constrained. Don’t go me wrong, all the Prusa Inquiry devices are outstanding machines, and I recommend them oft. Information technology’south just that the weak indicate of the system design is increasingly looking like the tiny LCD panel through which all information flows.

This tiny console displays merely iv lines of xx characters, and the company has done a terrific chore of squeezing data into that tiny window through the utilise of abbreviations, sliding text and flipping information.

But every bit nigh of the competing machines are now equipped with color touchscreens, a tiny LCD console is likely besides minor to present more than than complex data and functionality.

Prusa Research has delivered a touchscreen of their ain on the Prusa Mini, just their flagship line still uses the tiny LCD console. A potential upgrade for a “plus” version of the machines might include the same color touchscreen, but there’southward no word on that.

Meanwhile, another possibility is to only rely on an external arrangement like OctoPrint to provide a rich interface. I doubtable that’s what many ability users do these days.
